Quanta ransomware attack and questions to ask of supply chain security
Quanta Computer, a Taiwanese tech manufacturer has recently become a victim of the REvil ransomware group. The reason behind their targeting offers a glimpse at how ransomware groups are evolving their tactics.
Supply chains have been the security theme-de-jour since the Solarwinds attack in December 2020. That hasn’t escaped enterprise cyber-criminals either. While big brands like Apple may spend significant budgets on securing their networks, those of their suppliers may not be afforded the same luxury. Businesses benefit from outsourcing certain tasks (like manufacturing) and that naturally requires the exchange of information. While you may not have heard of Quanta before, you almost certainly have experienced their products. They employ 70,000 staff and makes over 30% of the world’s laptops. Their customers include Dell, HP, Amazon, Cisco, Microsoft and Facebook alongside Apple and a slew of other technology heavyweights.
In defence supply chain problems have been on the radar for some time: BAE Systems for example cites over 20,000 organisations in its supply chain. Some of them make nuts and bolts, others supply software and technology that controls sonar on submarines deep under the ocean surface. Understanding the provenance of what’s gone into a warship, fighter jet, or other ‘mission critical’ system is clearly desirable. Efforts have been underway to ensure these supply chains adhere to the U.K. government’s Cyber Essentials standard, as a minimum.
Other large, listed companies will have similarly sized supply chains of their own. That presents a great opportunity for criminals: extort the victim, then, or addition to, extort the victim’s customers too. Particularly secretive companies, like Apple, may be seen as particularly vulnerable or willing to pay up to keep innovations under wraps.
The scale of the problem is massive and it would be foolish to attempt to solve that independently. That is what lots of company supply chain security programmes currently do though: send out questionnaires asking tens, or even hundreds of questions that take ages to answer that may not discernibly improve the security posture of either organisation.
Promoting investment to raise the bar across your industry is a good first step. Basic cyber hygiene often gets overlooked in favour of newer, shinier technologies, but is critical to preventing these type of attacks. Ransomware groups are still getting in by using Administrator/123456 on Remote Desktop servers.
That just should be a thing, but without the right incentives from buyers or government-at-large, then supply chains may see it as a distraction as the same customers demand lower prices. Before commissioning a supply chain security programme businesses would be wise to get their basics in order (you are an important part of someone else’s supply chain, after all!) and consider the price that you are willing to pay for security.

Facebook wants to ‘normalise’ scraping, similar issue found that reveals private email addresses
Facebook accidentally (or, if you’re being cynical, deliberately) emailed an internal memo to a journalist in response to questions surrounding the social media network’s response to recent news that 533 million people’s personal data had been ‘scraped’ from their platform. Facebook is seeking to frame this as a regular industry occurrence. “Assuming press coverage continues to decline” reads the memo, “we’re not planning on additional statements on this issue.” The firm hopes that the public will move on and that it won’t have to answer more questions on why it was possible to upload address books containing every possible phone number on the planet that Facebook’s systems dutifully matched to personal profiles as friend suggestions. zdnet.com, theregister.com,
A similar issue in the way that the firm handles email addresses also surfaced this week after a security researcher was frustrated that the firm closed their vulnerability report and refused to patch the issue, despite it returning profiles where a user’s had set their email address information to private. wired.com
‘Moment of reckoning’ over ‘global operating system,’ says GCHQ
Widely reported interview with GCHQ director Jeremy Flemming this week covering the national security risks of not engaging in the development of new technology standards, such as 5G. The concerns are not new: ‘the West’ is giving up ground on the standards behind crucial new technology infrastructure implicitly to China, and they may not implement the same ideals of privacy or security (though the meaning of those terms doesn’t necessarily mean your privacy and security.)
The ‘Balkanisation of the Internet is progressing quite rapidly. Russia can ‘disconnect’ from the ‘net. China and other regimes have Great Firewalls that can control access. It is a far cry from the utopian vision that early academics had in mind of shared and open access to information.
The benefit of open over closed standards is obvious. This is about competing standards, their interoperability, and how the potential for misuse is minimised. The stakes are high - economically in terms of friction and market-size, ethically what is acceptable, as well as from a broader ‘security’ perspective - and it is easy to see why the sheer momentum of China, with almost one-sixth the world’s population would be a force to be reckoned with.

Signal strikes back at Cellebrite
Cellebrite offer services to help law enforcement unlock encrypted devices. The firm was involved allegedly involved in unlocking the San Bernardino shooter’s iPhone, ending a legal standoff between the FBI and Apple. Their solution works by identifying and exploiting cryptographic weaknesses, or just brute-forcing the content. At the end of last year, Cellebrite claimed to be able to crack Signal and give law enforcement access to encrypted chat messages. Now the CEO of Signal has hit back, pointing out numerous vulnerabilities in Cellebrite’s platform, including ‘decades old’ open source components, that can be exploited to alter the reports generated by the system. That’s a big deal for Cellebrite’s law enforcement customers who need the integrity of the reports to be iron-clad if they are to be used as evidence in court. The tit-for-tat is sure to be an as unwelcome distraction to Cellebrite as their claims were to Signal. theguardian.com
