Office 365 Voicemail Phishing Scam Warning

Security company McAfee has reported observing a phishing scam which uses a fake voicemail message to lure victims into entering their Office 365 email credentials into a phishing page.

How The Attack Works

According to McAfee’s blog, the first step in the phishing scam is the victim being sent an email informing them that they have missed a phone call.  The email includes a request to login to their account to access their voicemail.

The email message actually contains an HTML attachment which, when loaded, re-directs the victim to a phishing website. Although there are slightly different versions of the attachment, the most recent examples are reported to contain an audio recording which is designed to make the victim believe they are listening to the beginning of a legitimate voicemail.

Once re-directed to the bogus Microsoft account login page, the victim will see that their email address has already been loaded in the login field, thereby helping to create the illusion that this is their real Microsoft login page.

If the victim enters their password, the deception continues as they are shown a page saying that their login has been successful, and they are being re-directed to the home page.

Three Different Phishing Kits

Cybercriminals frequently buy-in phishing kits to launch their attacks. These are collections of software tools, created by professional phishers, that can be purchased and downloaded as a set. These phishing kits make it much easier for those with limited technical and coding skills or phishing experience to launch a phishing attack.

McAfee reports that as many as three different phishing kits are being used to make the fake websites involved in this scam. These are:

  1. Voicemail Scmpage 2019 – being sold on an ICQ channel, and used to harvest your email, password, IP Address and location details.
  2. Office 365 Information Hollar – similar to Voicemail Scmpage 2019 and used to harvest the same data.
  3. A third unnamed kit, which McAfee says is the most prevalent malicious page they have observed in the tracking of this particular campaign.  McAfee says that this kit appears to use code from 2017 malicious kit that was used to target Adobe users.

File Names For The Attachments

To help you spot this phishing attack McAfee has listed list the file names for attachments in the phishing email as being:

  • 10-August-2019.wav.html [Format: DD-Month-YYYY.wav.html]
  • 14-August-2019.html [Format: DD-Month-YYYY.html]
  • Voice-17-July2019wav.htm [Format: Voice- DD-MonthYYYYwav.htm]
  • Audio_Telephone_Message15-August-2019.wav.html [Format: Audio_Telephone_MessageDD-Month-YYYY.wav.html]

What Does This Mean For Your Business?

Reports indicate that this phishing attack has proved quite successful up until now, partly because the pages and steps appear authentic (and load the users email address as real login page does), and it uses social engineering and urgency (with audio) in a way that may prompt may people to suspend their critical faculty long enough complete the few short actions that it takes to give their details away.

The advice to businesses is, therefore, to be vigilant and to not open emails from unfamiliar sources or with unfamiliar attachments.  You may also want to use Two-Factor Authentication (2FA) where possible, and enterprise users may wish to block .html and .htm attachments at the email gateway level so that they don’t reach members of staff, some of whom may not be up to speed with their Internet security knowledge.

There is also a strong argument for not using the same password for multiple platforms and websites (password sharing).  This is because credentials stolen in one breach are likely to be tried on many other websites by other cybercriminals (credential stuffing) who have purchased/acquired them e.g. on the dark web.

Keeping anti-virus and software patches up to date and making sure that staff receive training and education about cybersecurity risks and what procedures should be followed if suspicious emails or other messages are spotted can also help companies to maintain good levels of cybersecurity.

Tough Questions About Libra Cryptocurrency

Facebook’s CEO, Mark Zuckerberg faced a grilling from the US Congress last week over his company’s ‘Libra’ cryptocurrency plans.

Libra

‘Libra’ is Facebook’s new cryptocurrency and global payment system that’s due to be launched in 2020.  Unlike other cryptocurrencies, Libra is backed by a reserve of cash and other liquid assets.  The idea of Libra is that spending the new currency could be as easy and fast as texting as payments can be made by a special phone app and by messaging services such as WhatsApp.  Also, Libra is intended to be of particular value to the one billion+ people around the world (including 14 million in the US) with no access to a bank account, but who could use a mobile phone-based payment system.

Management of the currency, units of which can be purchased via Libra’s platforms and stored it in a digital wallet called “Calibra” will be the responsibility of an independent group of 21 companies and non-profit organisations called the Libra Association, of which Facebook’s subsidiary ‘Calibra’ is a member.

Problems and Criticism

Facebook has, however, found itself coming in for some tough criticism over its involvement with Libra. This includes:

  • Worries about whether Facebook can be trusted with peoples’ financial details in the light of its part in the personal data-sharing scandal with Cambridge Analytica.
  • Concerns from ‘Group of Seven’ democracies finance chiefs about whether Libra could address “serious regulatory and systemic concerns”.
  • President Trump Tweeting that he’s not a fan of Libra, and bank chiefs like Mark Carney also expressing concerns about Libra.
  • Worries that Libra could be used as a means to bypass rules relating to money laundering and tax evasion (which is believed to have led to PayPal leaving the Libra Association recently).
  • Warnings that Libra could be blocked in Europe (especially in France) unless concerns over risks to consumers and to the monetary systems of countries can be addressed.

Congress Grilling

The grilling of Mark Zuckerberg at the US Congress last week at the top of the House Financial Service Committee’s hearing focused on many of the key concerns.  For example:

  • Republican Nydia Velázquez asked Mark Zuckerberg why Facebook should be trusted after the recent privacy scandals and data breaches/data sharing relating to the Cambridge Analytica affair.
  • Republican Joyce Beatty criticised Mark Zuckerberg over an apparent lack of knowledge of diversity and housing advertisement issues and alleged that Zuckerberg hadn’t read her reports.
  • Republican Patrick McHenry criticised the technology industry and highlighted the current anger towards it.

Prepared Statement Covered Many Concerns

Mark Zuckerberg’s prepared statement for the hearing appears have anticipated and answered the main concerns.  For example, as well as stressing how Facebook is committed to strong consumer protections for the financial information they receive, Mark Zuckerberg addressed three main concerns, saying that:

  1. Where people are concerned that Facebook is moving too fast on the Libra project, Facebook is committed to taking the time to get this right.
  2. Where it has been suggested that Facebook could circumvent regulators and regulations with Libra, Facebook won’t actually be a part of launching the Libra payments system anywhere in the world unless all US regulators approve it.
  3. Libra is not an attempt to create a sovereign currency but, like existing online payment systems, it’s simply intended to be a way for people to transfer money.

So What?

Despite the grilling, many commentators have pointed out that the House Financial Service Committee and Congress don’t actually have the power to do much about the introduction of Libra.  Some commentators have also suggested that the hearing was as much about political grandstanding as it was about Libra and that politicians are finding it hard to stay up to speed with information about cryptocurrencies.

No Regulatory Approval = Facebook Leaves the Association

Mr Zuckerberg stressed just how much he intends to play by the rules with Libra by saying that if the Libra Association moved forward without regulatory approval, Facebook “would be forced to leave the Association.”

What Does This Mean For Your Business?

Banks and governments are unlikely to adopt a favourable attitude to a new type of currency that could potentially unbalance monetary systems, and could potentially get around regulations, scrutiny and control, and could even be used for money laundering and tax evasion. That said, the blockchain-anchored Libra is unlikely to suffer many of the huge fluctuations and problems that other cryptocurrencies like bitcoin have because Libra is backed by real assets.  Also, many of the big financial players are part of the Libra Association e.g. Mastercard and Visa, although it’s clear that Facebook needs to make sure that Libra can meet all regulatory requirements and is squeaky clean if the Association wants to keep these important members.

If, as Mr Zuckerberg says, Libra is simply and innocently another way of paying for things that could lead to a more inclusive society e.g. by helping those without bank accounts, this could benefit not just society but whole economies too.  It looks as though Facebook still has some way to go, however, to convince governments, finance chiefs and other critics that it is the right company to be trusted with a new currency and the financial data of those who use it.

Amazon Echo and Google Home ‘Smart Spies’

Berlin-based Security Research Labs (SRL) discovered possible hacking flaws in Amazon Echo (Alexa) and Google Home speakers and installed their own voice applications to demonstrate hacks on both device platforms that turned the assistants into ‘Smart Spies’.

What Happened?

Research by SRL led to the discovery of two possible hacking scenarios that apply to both Amazon Alexa and Google Home which can enable a hacker to phish for sensitive information in voice content (vishing) and eavesdrop on users.

Knowing that some of the apps offered for use with Amazon Echo and Google Home devices are made by third parties with the intention of extending the capability of the speakers, SRL was then able to create its voice apps designed to demonstrate both hacks on both device platforms. Once approved by both device platforms, the apps were shown to successfully compromise the data privacy of users by using certain ‘Skills and actions’ to both request and collect personal data including user passwords by eavesdropping on users after they believed the smart speaker has stopped listening.

Amazon and Google Told

SRL’s results and the details of the vulnerabilities were then shared with Amazon and Google through a responsible disclosure process. Google has since announced that it has removed SRL’s actions and is putting in place mechanisms to stop something similar happening in future.  Amazon has also said that it has blocked the Skill inserted by SRL and has also put in preventative mechanisms of the future.

What Did SRL’s Apps Do?

The apps that enabled the ‘Smart Spy’ hacks took advantage of the “fallback intent”, in a voice app (the bit that says I’m sorry, I did not understand that. Can you please repeat it?”), the built-in stop intent which reacts to the user saying “stop” (by changing the functionality of that command after the apps were accepted), and leveraged a quirk in  Alexa’s and Google’s Text-to-Speech engine that allows inserting long pauses in the speech output.

Examples of how this was put to work included:

  • Requesting the user’s password through a simple back-end change by creating a password phishing Skill/Action. For example, a seemingly innocent application was created such as a horoscope.  When the user asked for it, they were given a false error message e.g. “it’s not available in your country”.  This triggered a minute’s silence which led to the user being told “An important security update is available for your device. Please say start update followed by your password.” Anything the user said after “start” was sent to the hacker, in this case, thankfully, SRL.
  • Faking the Stop Intent to allow eavesdropping on users. For example, when a user gave a ‘stop’ command and heard the ‘Goodbye’ message, the app was able to continue to secretly run and to pick up on certain trigger words like “I” or words indicating that personal information was about to follow, i.e. “email”, “password” or “address”. The subsequent recording was then transcribed and sent back to SRL.

Not The First Time

This is not the first time that concerns have been raised about the spying potential of home smart speakers.  For example, back in May 2018, A US woman reported that a private home conversation had been recorded by her Amazon’s voice assistant, and then sent it to a random phone contact who happened to be her husband’s employee. Also, as far back as 2016, US researchers found that they could hide commands in white noise played over loudspeakers and through YouTube videos in order to get smart devices to turn on flight mode or open a website. The researchers also found that they could embed commands directly into recordings of music or spoken text.

Manual Review Opt-Out

After the controversy over the manual, human reviewing of recordings and transcripts taken via the voice assistants of Google, Apple and Amazon, Google and Apple had to stop the practice and Amazon has now added an opt-out option for manual review of voice recordings and their associated transcripts taken through Alexa.

What Does This Mean For Your Business?

Digital Voice Assistants have become a popular feature in many home and home-business settings because they provide many value-adding functions in personal organisation, as an information point and for entertainment and leisure.  It is good news that SRL has discovered these possible hacking flaws before real hackers did (earning SRL some good PR in the process), but it also highlights a real risk to privacy and security that could be posed by these devices by determined hackers using relatively basic programming skills.

Users need to be aware of the listening potential of these devices, and of the possibility of malicious apps being operated through them.  Amazon and Google may also need to pay more attention to the reviewing of third party apps and of the Skills and Actions made available in their voice app stores in order to prevent this kind of thing from happening and to close all loopholes as soon as they are discovered.

Why You May Be Cautious About Installing The Latest Windows 10 Update

Some of Microsoft’s enterprise-based customers may be feeling cautious about installing the latest Windows 10 update because Microsoft warns that it could stop the Microsoft Defender Advanced Threat Protection (ATP) service from running.

The Update and Warning

The update in question is the October 15, 2019 KB4520062 (OS Build 17763.832).  The update contains a long list of improvements and fixes (see here for full details: https://support.microsoft.com/en-us/help/4520062/windows-10-update-kb4520062), but also three known issues, one of which concerns the Microsoft Defender Advanced Threat Protection (ATP) service.

What Is The ATP?

The ATP is a paid-for service, for Microsoft Enterprise customers (not Home or Pro customers) that’s designed to help enterprise networks prevent, detect, investigate, and respond to advanced threats. It offers features like endpoint behavioural sensors embedded in Windows 10, Cloud security analytics and access to threat intelligence generated by Microsoft hunters, security teams, and augmented by threat intelligence provided by Microsoft’s partners.

What’s The Issue With the Update?

In the update’s release notes Microsoft says, “We suggest that devices in an affected environment do not install this optional non-security update”.

The reason given for the warning is that installing the update could mean that the ATP service could stop running and may fail to send reporting data.  This could mean that certain enterprise customers are more exposed to security threats until a solution has been found.

Microsoft also warns that an error (0xc0000409) may be received in MsSense.exe.

Not Fixed Until November

Microsoft says that although it’s working on a resolution it estimates that it won’t have a solution to the problem until November.

One of Several Update Problems Recently

This is one of several updates from Microsoft recently that have come with problems.  For example, an update on the 16th of September was reported to have caused issues with Windows Defender.  Later in September, Microsoft had to issue two emergency Windows updates to protect against some serious vulnerabilities relating to Internet Explorer and Windows Defender (anti-virus software).

Also, the October 3 update is reported to have adversely affected the Start Menu and print spooler, and the Start Menu issues were reported to be still present following the 8 October update.

What Does This Mean For Your Business?

Although Home and Pro customers need not worry about this particular issue, Microsoft’s valued Enterprise customers, who have paid for the ATP service to help stay ahead of the game in security may be a little worried and frustrated at having to either wait until November to enjoy the improvements of the new (optional) update in safety, or install it now and risk the loss of their ATP service and face the associated potential security risks.

Microsoft customers seem to have suffered several problems related to updates in recent months, and Enterprise customers are likely to be those that Microsoft particularly does not want to upset.  It is likely, therefore, that Microsoft will be focusing of getting an appropriate solution to the new update issues before November if possible.

Equifax Hack Inevitable Says Lawsuit

A lawsuit against US Credit Rating Company Equifax relating to the massive 2017 hack alleges that the breaching of Equifax’s systems was “inevitable because of systemic organisational disregard for cybersecurity and cyber-hygiene best practices.”

What Happened

Back in September 2017, US Credit Rating Company Equifax was hacked and, in one of the largest recorded data breaches in history, an estimated 148 million customer details stolen, 44 million of which are believed to have come from UK customers.  Details stolen in the attack included names, US social security numbers, dates of birth, addresses, driver’s license details, and around 209,000 credit card numbers.

Hackers got in through a vulnerability in the website and Equifax was reported to have known about the attack 40 days before informing the public that it had happened.  Another aspect of the case that caused outrage at the time was the fact that three senior executives at the company were believed to have sold-off their shares worth almost £1.4m before the breach was publicly announced.

The Lawsuit

The lawsuit that was filed against Equifax with the Northern District Court of Georgia (Atlanta Division) in the US states that the breach was the “inevitable result of widespread shortcomings in Equifax’s data security systems”.

What Kind of Shortcomings?

The lawsuit alleges that Equifax’s data protection measures were “grossly inadequate,” and “failed to meet the most basic industry standards”.  The lawsuit paints a picture of a company with a shockingly simplistic and risky approach to the protection of personal data.  For example, it alleges that Equifax:

  • Failed to implement proper patching protocols and relied upon one individual to manually implement its patching process across its entire network.
  • Didn’t encrypt sensitive information and instead, stored in plain-text, making it easy for unauthorised users to read and misuse.
  • Didn’t encrypt mobile applications, meaning that it failed to encrypt data being transmitted over the internet.
  • Stored sensitive data on public-facing servers and left the keys to unlocking the encryption on those same public-facing servers, making it easy to remove the encryption from any data.
  • Used inadequate network monitoring practices and obsolete software.
  • Failed to implement adequate authentication measures.  This allegedly included using weak passwords and security questions.

Simple Usernames and Passwords Including ‘Admin’

One of the shocking accusations in the lawsuit relates to passwords.  It highlights how the New York Stock Exchange-listed firm responsible for protecting the sensitive personal data of millions of people used four-digit pins (derived from Social Security numbers and birthdays) to guard personal information, even though these weak passwords had already been compromised in previous breaches.

Also, the lawsuit alleges that Equifax relied upon the username “admin” and the password “admin” to protect a portal used to manage credit disputes, thereby making it incredibly easy for any hackers to guess.  For example, many penetration testing companies will use more obvious passwords such as ‘admin’ as a basic part of their testing of company systems.

Simple Passwords Still Widely Used

One of the main ways that we can all leave the door open to security breaches and hacks is by using simple, easy to guess passwords, and by sharing the same password between multiple websites and platforms.

For example, a study by the UK’s National Cyber Security Centre (NCSC) into breached passwords (in April this year) revealed that 123456 featured 23 million times, making it the most widely used password on breached accounts.  The study, which analysed public databases of breached accounts, also found that the second-most popular string was 123456789, and that the words “qwerty” and “password”, and the string 1111111 all featured in the top five most popular breached passwords.

What Does This Mean For Your Business?

The allegations about the apparent organisational disregard for cyber-security at such a big company and the use of simple, default-style passwords such as ‘Admin’ and leaving one person in charge of patching for the whole company are truly shocking.  The case highlights how some organisations may be too casual about how they manage and protect sensitive data, which is a dangerous position to be in, particularly with the possible fines from GDPR. Since most companies still rely upon passwords for many important systems and tools, this case particularly highlights how IT departments may need to implement processes to make sure that default passwords are changed to more secure ones, and that commonly used passwords are blacklisted.  Introducing multifactor authentication (MFA) also adds another important extra layer of security to password-based systems, and many companies are now seeking biometric authentication methods as a way of getting completely away from the whole risky password area.

The Equifax case also highlights how businesses shouldn’t treat database security any differently from other aspects of their cybersecurity, especially by not sharing admin passwords, and if sharing is necessary, by keeping track of who has those passwords and why. Using analytics on a database is also a way in which businesses can track when someone has got into a database using certain admin credentials.

Thomas Cook Customers and Employees Targeted By Phishing Attacks

Security researchers at Skurio Ltd have warned employees and customers of Thomas Cook to be vigilant after it detected the registration of 53 Thomas Cook-related domains in the week after the travel operator went into receivership.

Phishing Risk

The risk is that cyber-criminals may be seeking to exploit a search for information from customers and staff affected by the company’s collapse to launch phishing attacks.  For example, Thomas Cook-related domains that have been registered but don’t have a holding page or landing-page on them could be used to create a legitimate-looking email address as part of phishing attempts.

German Site

One of the Skurio analysts, John Evans, reported finding a .de Thomas Cook-related domain that hosted a page that pretended to be a legitimate business, but was using the Thomas Cook likeness to make money from customer refund claims.

25% Just Piggybacking

The Skurio researchers found that 25% of the domains registered appeared to be just simply piggybacking off the collapse of Thomas Cook, and were using their domains to simply redirect to other websites.

Holding Pages + Advert Clicks

The researchers discovered that 50% of the recently registered domains had holding pages for websites on platforms like Wix or WordPress (awaiting a full live site).  Some other domains were discovered to be used for ad clicks and ad revenue e.g. with adverts for booking a new holiday or finding jobs for Thomas Cook employees.

Thomas Cook Contracted Skurio

Skurio were monitoring the Thomas Cook-related domain situation because (as reported by Skurio) Thomas Cook, had contracted Skurio, long before its collapse, to monitor surface, deep and Dark Web sources in order to provide early data breach detection services.  It was as part this service Skurio was scanning for new domain registrations relating to Thomas Cook services.   According to Scurio, this scanning involved looking for domains set up with subtle spelling errors or additional terms that a customer may expect to see, in order send phishing emails, create fake social media accounts or capture customer details online.

What Does This Mean For Your Business?

It is not uncommon for cyber-criminals to launch campaigns to take advantage of a popular information search by customers after events such as a high-profile security breach or company collapse.  This is because people may let their guard down and may simply not suspect such an underhand tactic, which is the kind of human error based on emotion that cyber-criminals are counting on.

Phishing attacks are all-too-common, and a recent APWG report showed that phishing attacks continued to rise in summer of 2019, with cyber-criminals focusing branded webmail and SaaS providers.

Companies can help guard against phishing attacks by educating and training all staff to be able to spot possible fraudulent tactics, and by encouraging and empowering them to question and refer any suspicious activity that could help to protect the business. Having clear systems for staff to follow, including carefully verifying any new payment requests before authorising them, and continuously promoting online vigilance can be well worth the effort in the fight against phishing, and the generally increasing number of social engineering attacks that companies are facing.

Deepfake Ransomware Threat Highlighted 

Multinational IT security company ‘Trend Micro’ has highlighted the future threat of cybercriminals making and posting or threatening to post malicious ‘deep fake’ videos online in order to cause damage to reputations and/or to extract ransoms from their target victims.

What Are Deepfake Videos?

Deep fake videos use deep learning technology and manipulated images of target individuals (found online), often celebrities, politicians, and other well-known people to create an embarrassing or scandalous video such as pornography or violent behaviour. The AI aspect of the technology means that even the facial expressions of those individuals featured in the video can be eerily accurate, and on first viewing, the videos can be very convincing.

An example of the power of deepfake videos can be seen on the Mojo top 10 (US) deep fake video compilation here: https://www.youtube.com/watch?v=-QvIX3cY4lc

Audio Too

Deepfake ‘ransomware’ can also involve using AI to manipulate audio in order to create a damaging or embarrassing recording of someone, or to mimic someone for fraud or extortion purposes.

A recent example was outlined in March this year, when a group of hackers were able to use AI software to mimic (create a deep fake) of an energy company CEO’s voice in order to successfully steal £201,000.

Little Fact-Checking

Rik Ferguson, VP of security research and Robert McArdle, director of forward-looking threat research at Trend Micro recently told delegates at Cloudsec 2019 that deepfake videos have the potential to be very effective not just because of their apparent accuracy, but also because we live in an age when few people carry out their own fact-checking.  This means that by simply uploading such a video, the damage to reputation and the public opinion of the person is done.

Scalable & Damaging

Two of the main threats of deepfake ransomware videos is that they are very flexible in terms of subject matter i.e. anyone can be targeted, from teenagers for bullying to politicians and celebrities for money, and they are a very scalable way for cybercriminals to launch potentially lucrative attacks.

Positive Use Too

It should be said that deepfakes don’t just have a negative purpose but can also be used to help filmmakers to reduce costs and speed up work, make humorous videos and advertisements, and even help in corporate training.

What Does This Mean For Your Business?

The speed at which AI is advancing has meant that deepfake videos are becoming more convincing, and more people have the resources and skills to make them.  This, coupled with the flexibility and scalability of the medium, and the fact that it is already being used for dishonest purposes means that it may soon become a real threat when used by cybercriminals e.g. to target specific business owners or members of staff.

In the wider environment, deepfake videos targeted at politicians in (state-sponsored) political campaigns could help to influence public opinion when voting which in turn could have an influence on the economic environment that businesses must operate in.

Penetration Testing Specialists Who Broke Into US Courthouse Claim It Was Part of Security Assessment

Two security specialists who performed a physical break-in on the US courthouse that hired their company for a penetration test have claimed that their break-in was part of their assessment of security.

What Happened?

Dallas’ State Court Administration (SCA) is reported to have hired security company Coalfire Labs to conduct testing of the security of the court’s electronic records at the Dallas County Courthouse in the town of Adel, around 20 miles west of Des Moines.

The police were called to the courthouse just after midnight on the 11 September where two men, who had been seen walking around on the third floor, came to the door to meet the police.  When the two men, named as Justin Wynn and Gary Demercurio came to the door they were allegedly carrying multiple burglary tools, and allegedly claimed that they had been ‘contracted’ to break into the building and to check courthouse alarm system, and how responsive the police were.  The two men were promptly arrested, jailed and released on a $50,000 bond.

No Knowledge

It has been reported that, at the time, Dallas County claimed to have no knowledge of the security company or their plans, but Iowa’s State Court Administration did later release a statement confirming that it hired the company Coalfire Labs to test the security of the court’s electronic records.

The State Court Administration did, however say that, although it has asked the company to attempt unauthorised access to court records through various means to learn of any potential vulnerabilities, it didn’t intend or expect those means to include forced entry to the building, an act that it couldn’t not condone (certainly for cyber testing!).

Would A Physical Break-In Be Part of a Pen Test?

Some tech commentators have speculated that some cybercrimes require the criminal to be physically close to target devices, which would, therefore, require companies and organisations to perhaps consider investing in physical defences as well as cyber defences.

Coalfire

Coalfire Labs, the global company that was hired to carry out pen testing assessment, and is reported to have carried out hundreds of assessments for government agencies in the past, has been unable to comment on this particular case due to the confidential nature of its work, security and privacy laws, and the fact that a legal case is active.

Similar?

One thing that may not be good news for the two penetration testers is that there have been reports that a break-in at the Polk County Historic Courthouse in nearby Polk County on 9 Sept was apparently similar in nature to the Dallas County Courthouse break-in.

What Does This Mean For Your Business?

Physical security is, of course, an important part of protecting the whole business, but under GDPR data security should not involve leaving personal data anywhere that it could easily be accessed by unauthorised persons, whether its in a physical or virtual location.

Penetration testing is a legitimate and valuable way for companies and organisations to assess where more work needs to be done to ensure the safety of all digital data and information that they hold, but it is unlikely that many UK businesses would consider a physical break-in to be a legitimate part of what is usually and electronic-based assessment.  It remains to be seen what happens in the US court case.

Autonomous AI Cyber Weapons Inevitable Says Security Research Expert

Speaking at a recent CloudSec event in London, Trend Micro’s vice-president of security research, Rik Ferguson said that AI cyberattacks operated autonomously are an inevitable threat that security professionals must adapt to tackling.

If Leveraged By Cybercriminals

Mr Ferguson said that when cybercriminals manage to leverage the power of AI, organisations may find themselves experiencing attacks that happen very quickly, contain malicious code, and can even adapt themselves to target specific people in an organisation e.g. impersonating senior company personnel in order to get payments authorised, pretending to be a penetration testing tool, or finding ways to motivate targeted persons to fall victim to a phishing scam.

AI Vs AI

Mr Ferguson suggested that the inevitability of cybercriminals developing autonomous AI-driven attack weapons means that it may be time to be thinking in a world of AI versus AI.

Example of Attack

One close example given by Ferguson is the Emojet Trojan.  This malware, which obtains financial information by injecting computer code into the networking stack of an infected Microsoft Windows computer, was introduced 5 years ago but has managed to adapt and cover its tracks even though it is not even AI-driven.

AI Launching Own Attacks Without Human Intervention

Theresa Payton, who was the first women to be a White House CIO (under president George W Bush) and is now CEO of security consultancy Fortalice, has been reported as saying that the advent of genuine AI has posed serious questions, that the cybersecurity industry is falling behind, and that we may even be facing a situation where AI will be able to launch its own attacks without human intervention.

Challenge

One challenge to responding effectively to AI cyber-attacks is likely to be that cybersecurity and law enforcement agencies must move at the speed of law, particularly where procedures must be followed to request help from and arrange coordination between foreign agencies.  The speed of the law, unfortunately, is likely to be much slower than the speed of an AI-powered attack.

What Does This Mean For Your Business?

It is a good thing for all businesses that the cybersecurity industry recognises the inevitability of AI-powered attacks, and although it fears that it risks falling behind, it is talking about the issue, taking it seriously, and looking at ways in which it needs to change in order to respond.

Adopting AI Vs AI thinking now may be a sensible way to help security professionals, and those in charge of national security to focus thinking and resources on finding ways to innovate and create their own AI-based detection and defensive systems and tools, and the necessary strategies and alliances in readiness for a new kind of attack.

Joker Malware Found In 24 Apps In Google Play Store

Security researcher Aleksejs Kuprins of CSIS cybersecurity services company has discovered 24 apps which have been available for download in the Google Play Store that contain ‘Joker’ malware.

What Is Joker Malware?

Joker malware is a spy and premium subscription bot that makes money by simulating clicks. If, for example, a Joker infected app is downloaded, the malware delivers a second-stage component which silently simulates the interaction with advertisement websites, and steals the victim’s SMS messages, their contact list and their device information.

One of the silent automated interactions with advertisement websites includes simulation of clicks and entering of the authorisation codes for premium service subscriptions.

One specific example of what Joker can do, given by Mr Kuprins on the CSIS tech blog is that in in Denmark, Joker can silently sign a victim up for a 50 DKK (6,71 EUR) per week service by automating interaction with a premium offer’s webpage, entering the offer code, waiting for a SMS message with a confirmation code and extracting it, and finally submitting the code to the offer’s webpage to authorise the premium subscription.

Which Apps?

The 24 apps harbouring the ‘Joker’ malware, which have been installed more than 472,000 times are: Advocate Wallpaper, Age Face, Altar Message, Antivirus Security – Security Scan, Beach Camera, Board picture editing, Certain Wallpaper, Climate SMS, Collate Face Scanner, Cute Camera, Dazzle Wallpaper, Declare Message, Display Camera, Great VPN, Humour Camera, Ignite Clean, Leaf Face Scanner, Mini Camera, Print Plant scan, Rapid Face Scanner, Reward Clean, Ruddy SMS, Soby Camera and Spark Wallpaper.

Only Targets Certain Countries

The good news is that ‘Joker’ malware only attacks targeted countries and that most of the infected apps contain a list of these targeted Mobile Country Codes (MCC) meaning that the victim has to be using a SIM card from one of these countries to receive the second stage payload.  The bad news is that the UK is one of those targeted countries.

Google On Top Of Things

Despite there being 24 apps identified so far, Mr Kuprins has reported that Google has stayed on top of things during his investigation and has been removing all the offending apps without the need for prompting.

Not The First Time

Back in January last year, Security researchers discovered 36 fake and malicious apps for Android that could harvest data and track a victim’s location, masquerading as security tools in the trusted Google Play Store.

What Does This Mean For Your Business?

Google Play is a trusted source for apps, and it’s worrying that hundreds of thousands of customers may have the affected apps from Google Play.  In this case, Google has responded relatively quickly and has deleted infected apps where they have been found.

The obvious advice to android phone users is to check the list of infected apps and delete any on your phone that match. If you think you may have been affected by Joker via an app it may be a good idea to check your Google Play account for any unauthorised subscriptions, check your credit card or bank statements as far back as June of this year, and let your contacts know that you may have been infected (because Joker steals your phone’s contact list).

To minimise the risk of falling victim to damage caused by fake apps, users should check the publisher of an app, check which permissions the app requests when you install it, delete apps from your phone that you no longer use, and contact your phone’s service provider or visit the high street store if you think you’ve downloaded a malicious/suspect app.

This latest discovery of infected apps on Google’s Play Store should prompt the company to make even greater efforts to police the apps that it offers there.
