“Oi, China, stop it,” says White House and allies
US, Nato, the EU, the UK, Australia, Canada, New Zealand and Japan made statements this week naming and shaming Chinese state-backed actors as being responsible for the ‘Hafnium’ group attacks on Microsoft Exchange servers that affected over 30,000 organisations (vol. 4, iss. 10). Other groups, such as APT31 (aka Judgement Panda or Zirconium) and APT 40 (aka Jumper or Leviathan) were also tied to the Ministry of State Security and contractors of the Chinese State respectively.
The coordinated press releases coincided with the US Department of Justice charging four Chinese nationals, operating from Hainan Province from a front company, with the Exchange attacks.
While some tactics, techniques and procedures were released by the Cybersecurity and Infrastructure Agency (CISA) the main thrust of this action is strategic diplomacy than tactical cyber defence for organisations.
The US Secretary of State, Antony Blinken, called out irresponsible collaboration with cybercriminals and contractors:
“Responsible states do not indiscriminately compromise global network security nor knowingly harbour cyber criminals — let alone sponsor or collaborate with them,” — Antony Blinken
Much with the NSO Group story this week (see below): Spies gonna spy. It’s the wholesale exploitation of thousands of organisations and turning of a blind eye to criminal activities on the side that is central to the allegations.
Promising action if China doesn’t curb its cyber activity, Dominic Raab, UK Foreign Secretary, said “the Chinese Government must end this systematic cyber sabotage and can expect to be held account if it does not.”
Chinese diplomats dismissed the allegations as “groundless” and a “malicious smear” and urging abandonment of “ideological prejudice”.
Many companies rely on Chinese manufacturing or trade and this can weaken an individual country’s diplomatic position. By making multilateral action it makes it harder for China to counter.

NSO Group’s Pegasus malware tied to attacks on ’50,000’ individuals, but it may not be that clear-cut
Amnesty International, French investigative-journalism outfit Forbidden Stories and 16 media partners made headlines this week with claims of widespread ‘cyber-surveillance weapon abuse’. The claims stem from an investigation into Israeli spyware company NSO Group and their ‘Pegasus’ malware that is sold to government actors around the world.
The reporting centres around three aspects of the investigation:
- A leak of 50,000 phone numbers that may have been targeted
- Details and analysis of infrastructure used to deliver Pegasus malware
- Forensic analysis of the malware obtained from over 30 infected iPhones
Details and confidence in the latter two are strong and independently reviewed however there are questions over the scale of those that may have been targeted. NSO Group has denied the scale, pointed to targeting safeguards and suggested the list is from ‘Home Location Register’ lookups (services from telcos to determine the network and country of registration for a given SIM card).
While that shouldn’t be taken solely at face value, the articles I’ve seen focus much more on the forensic analysis of the malware than on the source and provenance of the leaked phone numbers.
The Guardian reporting on the source of the phone numbers is brief, caveated with “believed to be” language and that they are “people of interest by clients of NSO”. It shouldn’t come as much surprise that NSO clients - primarily government intelligence agencies - would be interested in other world leaders, business executives, union officials, religious leaders and some journalists.
In a recent ‘transparency’ report, NSO Group has claimed to have 45 Pegasus customers and that each targets an average of 112 targets annually. That would put the number at roughly 10% of the ‘bombshell’ 50,000 number that is driving a lot of headlines.
The vast majority of people need not worry: these tools require huge amounts of resources to develop, are expensive to purchase and are unlikely to be used against you except if you’re of interest to international actors or high-level law enforcement agencies.
That’s important context though shouldn’t diminish from the worthwhile discussion about oversight and export control of for-profit spyware.
Mastercard banned from taking on new customers in India
In 2018 India introduced a rule barring payments companies from transferring customer data overseas. Now the central bank the Reserve Bank of India has barred Mastercard from adding new customers.
Data sovereignty rules are becoming increasingly popular, often introduced alongside other data protection legislation and regulation. That’s creating a growing compliance headache for international businesses and especially online/tech businesses: some apply ‘extraterritorially’ meaning the rights are afforded regardless of the business’ established jurisdiction.
Often badged as ‘privacy’ regulations businesses operating internationally may wish to carefully consider the risk scenarios associated with hosting data in different jurisdictions.
Google bricked a load of Chrome OS devices because of a typo in update
Google bricked some Chrome OS devices after pushing out an update with a single-character typo that broke password validation. A simple unit test should have caught the error, plus updates are meant to go through three test channels’ before being considered for prime-time. That they didn’t detect this suggests Google’s code review, quality assurance and release processes are, well, perhaps not consistently up to scratch. Mountain View suggests users ‘not reboot’ their devices. Wonderful.
Respect In Security initiative launches to stamp about harassment and abuse in the cyber industry
Out of a Cyber House Party panel discussion has some a movement to stamp out abuse and harassment in the cyber security profession. A survey of 302 cyber pros has revealed that 32% of them have experienced harassment online, rising to 35% in-person. The Respect In Security initiative stands against harassment both online and in the workplace.
Showing effective risk management adds value
Avoiding the negative consequences of risk events can be something difficult to prove the benefit of. All being well you will have spent the capital and nothing bad will have happened. Would it have not happened without investing the resources: we’ll never know.
However, there is evidence that higher-performing organisations have more mature risk management processes. What’s more, data of large publicly traded companies that suffered data breaches and went on to ‘underperform the market’ (vol. 1, iss. 13) typically were under-performing before their breach. Correlation does not equal causation, though it seems logical that poor governance and risk management may lead to an increased probability of consequential cyber security incidents.
Risk consultancy Broadleaf collated a good summary of the empirical evidence of good enterprise risk management (cyber risk being a component of that) back in 2019. It’s a good read that concludes…
“There is clear evidence that companies with risk management processes generate better financial and business outcomes than those without. There is also clear evidence that companies with higher levels of risk management maturity perform better than those with lower levels of maturity.”

Hiding malware in machine learning models
This is some cool research: it’s possible to hide malware inside machine learning models, while still having them perform their intended task, suggesting they wouldn’t be detected. The study — EvilModel: Hiding Malware Inside of Neural Network Models — by Zhi Wang, Chaoge Liu, Xiang Cui shows that 36.9MB of malware can be embedded into a 178MB-AlexNet model within 1% accuracy loss. It’s not something to run out and start worrying about but an interesting example of steganography.
