Krack WiFi Attack: Vulnerabilities in WPA2 Protocol

All Wi-Fi connections are potentially vulnerable to a newly discovered security attack called "Krack", which allows an attacker to listen in on internet traffic (a Man-in-the-Middle Attack) over a wireless network. 

In theory, a hacker could read your web and email communications, and even inject malware like ransomware onto your device. Krack takes advantage of unpatched Apple, Android, and Windows operation systems, while unpatched Wi-Fi access points can be manipulated to orchestrate the man-in-the-middle attack.

The sky is not falling in on WiFi, this is not like the WEP protocol situation of many years ago, WEP is a security protocol fundamentally flawed by design, WPA2 encryption is not broken, the software that uses it needs to be corrected to secure it. Wireless Access Points (APs) and operating systems that use WPA2 are (or soon will be) patchable, which protects them from this attack.

For a video demo of the attack see - https://www.krackattacks.com/#demo 
For the full technical details of the WPA2 flaw and attack method see - https://papers.mathyvanhoef.com/ccs2017.pdf

Wireless Usage Advice
  • Make sure your laptop operating system has the very latest security updates patched (always) i.e. Windows, Linux, Mac. Microsoft said they have already patched Windows systems, but at this time have not confirmed details about which patch it was. Several Linux distributions have released patches for the flaw.
  • Make sure your smartphone and tablet devices have the latest security updates patched, especially Android devices, and Apple, and Windows (if anyone still uses it)
  • As always, if you are going to use public WiFii networks, my first suggestion is to avoid using public WiFi, but if you are, use VPN software. Using a secure VPN will protect you against "Krack exploited" public WiFi access points, regardless of patching and whether AP is exploited. Failing that, if you like to take risks with your personal and confidential information, as a very last resort ensure you use "https://" websites only, and be extra vigilant the "https://" do not revert to "http://".  If it does, it is a clear sign of a compromised wireless network and of your connection to it.

Preventing Your Wireless Access Point from being Exploited
Wireless Access Points (AP) firmware versions are presently being updated and released to fix this WPA2 flaw, apply them with they are released - see https://www.kb.cert.org/vuls/id/228519/. AP firmware patches are often missed, as routers updates tend not to be applied automatically.

Cyber Security Roundup for September 2017

A massive data breach at Equifax dominated the UK media finance headlines this month, after 143 million customer records were compromised by a cyber-attack, 400,000 of which were UK customer accounts. Hackers took advantage of Equifax’s negligence in not applying security updates to servers. The data breach has already cost the CEO, CIO and CISO their jobs. In the UK Equifax faces investigations and the prospect of significant fines by both the Financial Conduct Authority and the Information Commissioner's Office over the loss of UK customer financial and personal data respectively.

Hackers stole a quarter of a million Deloitte client emails, follow the breach Deloitte was criticised by security professional for not adopting two-factor authentication to protect the email data which they hosted in Microsoft’s Azure cloud service.

September was an extremely busy month for security updates, with major patches releases by Microsoft, Adobe, Apache, Cisco and Apple to fix an array of serious security vulnerabilities including BlueBorne, a Bluetooth bug which exposes billions of devices to man-in-the-middle attacks.

UK government suppliers using Kaspersky to secure their servers and endpoints may well be feeling a bit nervous about the security software after Kaspersky was banned by US Government agencies. The US Senate accused the 20-year-old Russian based security company as being a pawn of the Kremlin and posing a national risk to security. Given the US and UK intelligence agency close ties, there are real fears it could lead to a similar ban in the UK as well. A UK ban could, in theory, be quickly extended to UK government suppliers through the Cyber Essentials scheme, given the Cyber Essentials accreditation is required at all UK government suppliers.

While on the subject of the Russia, the English FA has increased its cybersecurity posture ahead of next year's World Cup, likely due to concerns about the Russian Bears hacking group. The hacking group have already targeted a number of sports agencies in recent months, including hacking and releasing football player's world cup doping reports last month. 

In the last couple of weeks, I was Interviewed for Science of Security, and I updated my IBM Developer Works article on Combating IoT Cyber Threats.

Science of CyberSecurity: Latest Cyber Security Threats

As part of a profile interview for Science of Cybersecurity I was asked five questions on cyber security last week, here's question 5 of 5.

Q. What keeps you up at night in the context of the cyber environment that the world finds itself in?
The growing dependence and integration of connected computers within our daily lives, means we are embarking on an era where cyber attacks will endanger our lives. Networked and complex IT systems are inherently insecure, meaning it is open season for nation-states, cyber terrorists and the curious to attack these life integrated emerging technologies, from driverless cars and countless new home IoT devices. I fear it will only be a matter time before a cyber attack causes human harm or even loss of life. The impact of the recent NHS ransomware attack serves as a warning, this cyber attack directly caused the closure of accidental and energy departments and the cancellation of operations. The future threats posed artificial intelligence and quantum computing are also growing concerns for cyber security, and well worth keeping an eye as these technologies continue to progress.

Science of CyberSecurity: What Cyber Security Blogs to Follow

As part of a profile interview for Science of Cybersecurity I was asked five questions on cyber security last week, here's question 4 of 5.


Q. Do you recommend a particular cyber security blog that our readers could follow?
Of course, my own IT Security Expert Blog, and my Twitter accounts @SecurityExpert and @SecurityToday are well worth following.  My two favourite blogs are Bruce Schneier’s blog, Bruce is a true rock star of the industry, and Krebs on Security blog is also an excellent read, Brian provides the behind the scenes details of the latest hacking techniques and data breaches, and pulls no punches with his opinions. Both these bloggers have books that are a must read for budding cyber security professionals as well.

Science of CyberSecurity: Where to get CyberSecurity Science

As part of a profile interview for Science of Cybersecurity I was asked five questions on cyber security last week, here's question 3 of 5.

Q. Where do you go to find your “science” of cybersecurity?
While cyber security controls appear simple to follow in policy statements and best practice guides, the reality is they are not always easy to implement across diverse organisations. When attempting to resolve complex security problems it can be easy for security professionals to lose sight of the goal of cyber security. To keep clarity, I think it helps to strips away the technology from the problem, and learn the security science and lessons from history.  So reading military strategy books like Sun Tzu’s “The Art of War” can improve how you think about and assess the cyber adversaries facing the organisation. Delving into the science of psychology is invaluable when seeking to bring about effective and positive staff security awareness and behavioural changes in the workplace.

Science of CyberSecurity: Reasons Behind Most Security Breaches

As part of a profile interview for Science of Cybersecurity I was asked five questions on cyber security last week, here's question 2 of 5.

Q. What – in your estimation – are the reasons behind the many computer security breaches/failures that we see today?
Simply put insecure IT systems and people are behind every breach, insecure IT systems are arguably caused by people as well, whether it is poor system management, lack of security design, insecure coding techniques, and or inadequate support, it all boils down to someone not doing security right. For many years seasoned security experts have advocated that people are the weakest link in security, even hackers say ‘amateurs hack systems, professionals hack people’, yet many organisations still focus most of their resources and funds heavily on securing IT systems over providing staff with sustained security awareness. Maybe this is a result of an IT security sales industry over hyping the effectiveness of technical security solutions. I think most organisations can do more to address this balance, starting with better understanding the awareness level and risk posed by their employees. For instance, the security awareness of staff can be measured by using a fake phishing campaign to detect how many staff would click on a link within a suspicious email. While analysing the root causes of past cyber security incidents is a highly valuable barometer in understanding the risk posed by staff, all can be used as inputs into the cyber risk assessment process.

Science of CyberSecurity: Thoughts on the current state of Cyber Security

As part of a profile interview for Science of Cybersecurity I was asked five questions on cyber security last week, here's question 1 of 5.


Q. What are your thoughts on the current state of cybersecurity, both for organizations and for consumers?
Thanks to regular sensational media hacking headlines most organisational leaders are worried about their organisation’s cyber security posture, but they often lack the appropriate expert support in helping them properly understand their organisation’s cyber risk. To address the cyber security concern, an ‘off the peg’ industry best practice check box approach is often resorted to. However, this one-size-fits-all strategy is far from cost effective and only provides limited assurance in protecting against modern cyber attacks, given every organisation is unique, and cyber threat adversaries continually evolve their tactics and methodologies. In these difficult financial times of limiting cyber security budgets, it is important for the cyber security effort to be prioritised and targeted. To achieve this, the cyber security strategy should be born out of threat intelligence, threat assessing and a cyber risk assessment. This provides organisational leaders with the information to take effective cyber security strategy decisions, and to allocate funding and resources based on a subject matter they do understand well, business risk. Nothing can ever be 100% safeguarded; cyber security is and always should be a continual risk based undertaking, and requires an organisation risk tailored cyber security strategy, which is properly understood and led from the very top of the organisation. This is what it takes to stay ahead in the cyber security game.

Cyber Security Roundup for August 2017

TalkTalk yet again made all the wrong cyber security headlines in the UK this month, after it was handed a £100,000 fine by the Information Commissioner's Office (ICO) for not adequately protecting customer records from misuse by its staff. The ICO investigated the Internet Service Provider after receiving complaints from customers, who said they received cold calls from scammers who knew their TalkTalk account information.

Second-hand goods firm CeX disclosed a compromise of up to 2 million online customer accounts due to a hack, however, CeX has yet to disclose any details about the cyber attack. My blog post and advice about this is here http://blog.itsecurityexpert.co.uk/2017/08/up-to-2-million-cex-customer-account.html

Hackers had a field day taking over social media accounts, from Real Madrid and FC Barcelona to Game of Thrones, much embarrassment could have been avoided if they had adopted multi-factor authentication on the accounts, aside from the spate of Instagram hacks which were caused by the exploitation of a software vulnerability, namely within Instagram's API.

In what looks like a follow on from the UK's Parliament's email brute force email account attack in June, the Scottish Parliament was hit by a very similar cyber attack, it was reported, as per the Westminister attack, many SMPs were found to be using weak passwords. Let's hope the Welsh Assembly have taken note and have learned the password security lessons.

A massive 'spambot' holding 711 million email addresses was found to be spreading malware by a security researcher. It was said to have been put together using stolen data from previous LinkedIn and Badoo data breaches. Using legitimate email addresses helps in the avoidance of anti-phishing and spam filters.

On the ransomware front, LG reported WannaCry caused a two-day shutdown of its business in South Korea. TNT customers were said to be furious after NotPeyta badly affected its ability to deliver hundreds of thousands of items, particularly within in the Ukraine. And Digital Shadows reported a trend in cyber criminals dropping Exploit kits for Ransomware, as there is simply a lot more money to be made out of ransomware attacks.

On the critical security patching, Microsoft released 25, Adobe released 43, and Drupal patched a critical bug. And there was an interesting article posted by Microsoft on Cyber Resilience worth reading.

Up to 2 Million CeX Customer Accounts Compromised by Security Breach

If you are a CeX online customer, change your account password now, as the second hand UK goods chain has been informing over two million of its customers their personal details have been hacked. In a customer email CeX discloses they have been the subject of a security breach by a third party, and that's about as much detail as CeX are presently admitting about the cyber attack at the moment.

Despite the CeX email referring to a "sophisticated breach of security" without any further detail about what happened, it is impossible to judge whether it was actually a sophisticated cyber attack or not. Rather oddly CeX have not forced a password change on their compromised customer accounts despite admitting account passwords were at risk.  

My CeX Customer Advice
  • Change your CeX password straight away. Ignoring the CeX website advice of using a 6 character password, which is too weak - see the Account Password section of this post below.  Alternatively you could also close your CeX account through the website
  • If you have used your old CeX password on any other websites, change those account passwords quickly. 
  • Be vigilant for personalised scam emails from CeX, given cyber criminals might have your email address and know you are a CeX customer.
  • Review your Credit Card statement and Bank Statements for suspicious activity. Note CeX might have put your bank account details and BitCoin address at risk/

Data Compromised
CeX have not been too clear on detailing the customer account data that is at risk, stating  "The data includes some personal information such as first name, surname, addresses, email address and phone number if this was supplied". And "In a small number of instances, it may include encrypted data from expired credit and debit cards up to 2009. No further financial information has been shared."   

Reviewing a CeX website account suggests the following customer account personal data is at risk:
Email Address
BitCoin Address
Full Address
Bank Details - Account Holder Name, Sort Code, Account Number, Roll Number
Phone Number

It is concerning CeX refer to storing debit/credit card details past their expiry dates - why? CeX also appear to be glossing over the significance of compromised customer debit/credit card details in stating " We would like to make it clear that any payment card information that may have been taken, has long since expired".  A rather misleading statement given some payment card issuers use the debit/credit card number when reissuing new cards, and the new expiry date is guessable. Given that statement, you  have to wonder whether the CeX operation was secure enough to handle debit/credit card data, are CeX PCI DSS compliant.? Payment Card Industry Data Security Standard compliance is required for all organisations which process, store and/or transmit debit/credit card details, no PCI DSS compliant organisation ever been successfully breached.

Account Password
CeX also states the account passwords were not been stored in plain text, but have not advised how the passwords were protected. For instance, whether passwords were stored using a unique value (salt) together with the password before being scrambled with an industry recognised one-way hashing algorithm (adequate security protection), or by just using the hashing algorithm on the password (inadequate security protection). 
Change your CeX password

CeX recommends a 6 character password or longer on their website's password change process which is too weak. CeX customers should avoid setting that minimum 6 character strength, go for an at least 8 character password consisting of at least one number, one upper case character, one lower case and one special character (i..e #!"£$%^&). I recommend using a password manager (see advice on https://www.itsecurityexpert.co.uk) to generate a unique and secure random password of at least 12 characters to really be on the safe side.

By the CeX requires you know your old password in order to change it, so you'll have to hope the hacker hasn't changed your password.

CeX also has a "Cancel Your Account Option" which I assume will remove all personal data from CeX, customer's could submit a Data Subject Access Request to CeX after account closure to be certain.

Breach Recovered and Fixed?
CeX say "Our cyber security specialists have already put in place additional advanced measures to fix the problem and prevent this from happening again.", however, without any detail about the hack and the new measures put in place, this statement provides little assurance to CeX customers. The following statement also skirts what customers want to know  "additional measures were required to prevent such a sophisticated breach occurring and we have therefore employed a cyber security specialist to review our processes. Together we have implemented additional advanced measures of security to prevent this from happening ". If this cyber attack turns out not to be sophisticated, CeX can expect heavy criticism by a more cyber entitled media, and interest from the Information Commissioner's Office for violating the Data Protection Act.

CeX Email
Dear Customer,
We are writing to inform you that unfortunately we have recently been subject to an online security breach. We are taking this extremely seriously and want to provide you with details of the situation and how it might affect you. We also want to reassure you that we are investigating this as a priority and are taking a number of measures to prevent this from happening again.
The situation
As a result of a breach of security in which an unauthorised third party accessed our computer systems, we believe that some customer data has been compromised. This includes personal information, and, for a small number of customers, it also includes encrypted data from expired credit or debit cards. As a customer of CeX, there is a possibility this might affect you.
Please note, we did not have any card data stored for your account. We ceased storing customer card details in 2009.
What we’ve done about it
This was a sophisticated breach of security and we are working closely with the relevant authorities to help establish who was responsible. Our cyber security specialists have already put in place additional advanced measures to fix the problem and prevent this from happening again.
What we suggest you do?
  • Although we have put in place additional security measures, we recommend that you change the password for your webuy online account.
  • If you used the same password elsewhere, we also suggest that you change your password for those accounts.
Further details on this issue are provided in a Q&A below. If you have additional questions, please email us at: guidance@webuy.com where we will be compiling the most frequently asked questions, which will then be updated via uk.webuy.com/guidance
We apologise for inconvenience this may cause.
Yours sincerely,
David Mullins
Managing Director


Questions & Answers
How much data has been compromised?
As a precautionary measure we are contacting up to two million of our registered website customers who could potentially be affected.
Does this affect in-store membership personal information?
We have no indication that in-store personal membership information has been compromised.
What does the data include?
The data includes some personal information such as first name, surname, addresses, email address and phone number if this was supplied. In a small number of instances, it may include encrypted data from expired credit and debit cards up to 2009. No further financial information has been shared.
What about financial data?
A small amount of encrypted data from expired credit and debit cards may have been compromised. We would like to make it clear that any payment card information that may have been taken, has long since expired as we stopped storing financial data in 2009.
What has happened to the data that has been compromised?
We are aware that an unauthorised third party has accessed this data. We are working closely with the relevant authorities, including the police, with their investigation.
What should I do?
We advise that you change your webuy.com password, as well as any other online accounts where you may share the same password, as a precautionary measure.
Why do I need to change my passwords?
Although your password has not been stored in plain text, if it is not particularly complex then it is possible that in time, a third party could still determine your original password and could attempt to use it across other, unrelated services. As such, as a precautionary measure, we advise customers to change their password across other services where they may have re-used their WeBuy website password.
Can customers find out exactly what data has been shared about them?
At this stage, it is not possible for us to share this information as we are still undergoing an investigation. At this stage, we are alerting all customers who might have been affected as a precaution.
What security do you have in place to protect this data?
We take the protection of customer data extremely seriously and have always had a robust security programme in place which we continually reviewed and updated to meet the latest online threats. Clearly however, additional measures were required to prevent such a sophisticated breach occurring and we have therefore employed a cyber security specialist to review our processes. Together we have implemented additional advanced measures of security to prevent this from happening again.

Cyber Security Roundup for July 2017

Apologises for the delay in this month's Cyber Security Roundup release, I been away on holiday and taking a breach for monitor screens and keyboards for a couple of weeks.

The insider threat danger manifested at Bupa where an employee stole and shared 108,000 customer health insurance records. Bupa dismissed the employee and is planning to take legal action. The Bupa data breach was reported both to the FCA and the ICO, it remains to be seen if the UK government bodies will apportion any blame onto Bupa for the data loss. 

The AA was heavily criticised after it attempted to downplay a data compromise of over 13 gigabytes of its data, which included 117,000 customer records. The AA’s huge data cache was incorrectly made available online after an AA online shop server was “misconfigured” to share confidential data backup files.

A customer databreach for the World Wrestling Entertainment (WWE) should serve as a stark warning for businesses to adequately assure third parties and to secure hosted cloud systems. Three million WWE fan records were compromised after a third party misconfigured a cloud hosted Amazon server used by the WWE online shop.

The aftershock of Peyta \ NotPeyta rumbles on with, with malware still reported as disrupting firms weeks after the attack. There there are claims the mass media coverage of the attack have improved overall staff cyber security awareness.

It was found that over 1.6 million NHS patient records were illegally provided to Google's artificial intelligence arm, DeepMind, without patient concern meant the NHS and Google have breached the Data Protection Act.

A 29 year old British hacker named as Daniel K, but better known by his hacker handle "BestBuy" or "Popopret" admitted to hijack of 900,000 Deutsche Telekom routers in Germany after he was arrested at Luton airport in February. He said he made "the worst mistake of my life" when he carried out a failed attack in November for a Liberian client who paid him 8,500 Euros to attack the Liberian's business competitors. BestBuy used a variant of the Mirai malware to take advantage of a security vulnerability in Zyxel and Speedport model routers which were used by Germany Internet Service provider, with his intention to increase his botnet, and so the scale of DDoS attacks he could perform on behalf of clients.

A document from the National Cyber Security Centre (NCSC) was obtained by Motherboard and was verified by the BBC with NCSC as being legitimate. The document states some industrial software companies in the UK are "likely to have been compromised" by hackers, which is reportedly produced by the British spy agency GCHQ. The NCSC report discusses the threat to the energy and manufacturing sectors. It also cites connections from multiple UK internet addresses to systems associated with "advanced state-sponsored hostile threat actors" as evidence of hackers targeting energy and manufacturing organisations.

UniCredit Bank had over 400,000 customer loan accounts accessed through a third party. This is the second security breach at the Italian bank in a year.

Cyber Security Roundup for June 2017

Another large scale ransomware cyber attack caused chaos and dominated the media headlines around the world this month. The Petya ransomware, a copycat of WannaCry, caused major operational impact to organisations neglecting to apply Microsoft Windows critical security updates. There were reports of the malware significantly impacting British marketing firm WPP, a Jewson hardware store, Ukrainian national infrastructure associated firms, and even halting production at a Cadbury chocolate factory in Australia.

Aside from the Peyta ransomware outbreak, it was another busy month of significant cyber security attacks and data compromises across the UK. The UK Parliament's email system was hacked with around 90 email accounts compromised due to the usage of weak passwords by parliament staff, it is not certain how many of 90 were MPs or not, but I wouldn't surprised if there were more than a few using weak passwords. There were further cyber troubles for the UK government after its Digital Service website data.gov.uk data was compromised. Virgin media told 800,000 of its users to change their router passwords after it was discovered that hackers could access Virgin's Super Hub 2 routers. And there was yet more critical security patches released this month, as Microsoft and application vendors fight to stay ahead of cyber criminals and nation-state actors software exploits.

Over in the United States, a US Health Insurer forked out £90 million to cover compensation and legal costs after hackers stolen customer records in its care. We could well see these types of large payouts in the UK soon after the General Data Protection Regulation (GDPR) kicks in May 2018. The GDPR gives the Information Commissioners Office (ICO) new powers to fine up to 10 Million Euros or 2% the previous year global turnover of the company, for any cyber security breaches. Data subjects will also have the right to take companies to court to seek damages as well. The ICO will get double those penalty rates for privacy rights breaches, ouch! Under the GDPR companies are forced to fess up to all security incidents which compromises or places personal data at risk, both to the ICO and to each data subject impacted, so there will be no hiding place for security breaches in the UK after next May.

Finally, US Cert and Incapsula released an interesting advisory about 'Hidden Cobra', a North Korean Cyber Threat group. This nation-state group is seemingly ramping up their capabilities at the moment, and are behind the DeltaCharlie campaign and linked with the WannaCry ransomware outbreak last month, well worth a read.
