A week ago, we saw a procession of nervous headlines after the Times and then Bloomberg reported that Facebook, its messaging platform WhatsApp and others would now be forced to disclose encrypted messages to law enforcement agencies under a new treaty between the U.S. and the U.K. As I commented at the time, these reports were misleading, mixing up agreements to share data that already exists with changes in the law to break encryption. But now the U.S. and U.K., as well as Australia, are set to write to Facebook to request that the company pauses its plans for cross-platform messaging encryption until backdoors can be added, citing public safety and serious crime as its reasons.EFF described the letter as an “all-out attack on encryption... a staggering attempt to undermine the security and privacy of communications tools used by billions of people,” and urged Facebook not to comply. The organization warned that the move would endanger activists and journalists, and could be used by “authoritarian regimes... to spy on dissidents in the name of combatting terrorism or civil unrest.”

Today, March 31st 2017, WikiLeaks releases Vault 7 "Marble" -- 676 source code files for the CIA's secret anti-forensic Marble Framework. Marble is used to hamper forensic investigators and anti-virus companies from attributing viruses, trojans and hacking attacks to the CIA. Marble does this by hiding ("obfuscating") text fragments used in CIA malware from visual inspection. This is the digital equivallent of a specalized CIA tool to place covers over the english language text on U.S. produced weapons systems before giving them to insurgents secretly backed by the CIA. Marble forms part of the CIA's anti-forensics approach and the CIA's Core Library of malware code. It is "[D]esigned to allow for flexible and easy-to-use obfuscation" as "string obfuscation algorithms (especially those that are unique) are often used to link malware to a specific developer or development shop." The Marble source code also includes a deobfuscator to reverse CIA text obfuscation. Combined with the revealed obfuscation techniques, a pattern or signature emerges which can assist forensic investigators attribute previous hacking attacks and viruses to the CIA. Marble was in use at the CIA during 2016. It reached 1.0 in 2015.

The source code shows that Marble has test examples not just in English but also in Chinese, Russian, Korean, Arabic and Farsi. This would permit a forensic attribution double game, for example by pretending that the spoken language of the malware creator was not American English, but Chinese, but then showing attempts to conceal the use of Chinese, drawing forensic investigators even more strongly to the wrong conclusion, --- but there are other possibilities, such as hiding fake error messages. The Marble Framework is used for obfuscation only and does not contain any vulnerabilties or exploits by itself.

NSO Group, an Israeli vendor of “lawful” hacking tools designed to infect a target’s phone with spyware, is regarded by many as a bad actor. The group claims to be shocked when its products are misused, as they have been in Mexico, Saudi Arabia and the United Arab Emirates. One incident might be excusable, but the group’s continued enabling of misbehavior has resulted in well-earned enmity. Recently, Facebook struck back. NSO Group deployed a weaponized exploit for Facebook’s WhatsApp messenger, integrated it into its Pegasus malcode system, and offered it to its customers (a mix of legitimate government agencies and nefarious government actors) interested in hacking WhatsApp users beginning in April. This was a particularly powerful exploit because it required no user interaction and the only sign of the exploit a user might discover would be a series of “missed calls” received on the user’s phone. Facebook patched the vulnerability on May 13, blocking the NSO campaign. Facebook wasn’t satisfied with simply closing the vulnerability. In cooperation with CitizenLab, Facebook identified more than 100 incidents in which NSO Group’s WhatsApp exploit appeared to target human rights activists and journalists. In total, Facebook and CitizenLab identified 1,400 targets (which apparently also included government officials in U.S. allied governments). They then filed a federal lawsuit against NSO Group, closed NSO Group member accounts, and, most damaging of all to NSO’s customers, sent a notice to all identified victims alerting them of the attack. This meant that all targets, both dissidents and drug lords alike, were notified of this surveillance. The lawsuit will be a case to watch. Facebook has already revealed a large amount of detail concerning NSO Group’s internal workings, including the hands-on nature of its business model: NSO Group actively assists countries in hacking targets. For example, we now know that while an NSO Group employee may not press the “Enter” key for a target, NSO employees do act to advise and consult on targeting; and NSO Group is largely responsible for running the infrastructure used to exploit targets and manage implants. Expect more revelations like this as the case proceeds.

Amidst an escalating trade war and political tensions with the US, Beijing officials have decided to develop a custom operating system that will replace the Windows OS on computers used by the Chinese military.

Beijing officials are well aware of the US' hefty arsenal of hacking tools, available for anything from smart TVs to Linux servers, and from routers to common desktop operating systems, such as Windows and Mac.Since these leaks have revealed that the US can hack into almost anything, the Chinese government's plan is to adopt a "security by obscurity" approach and run a custom operating system that will make it harder for foreign threat actors -- mainly the US -- to spy on Chinese military operations.
