On 9 August, QuoIntelligence disseminated a Warning to its government customers about a new APT28 (aka Sofacy, Sednit, Fancy Bear, STRONTIUM, etc.) campaign targeting government bodies of NATO members (or countries cooperating with NATO). In particular, we found a malicious file uploaded to VirusTotal, which ultimately drops a Zebrocy malware and communicates with a C2 in France. After our discovery, we reported the malicious C2 to the French law enforcement as part of our responsible disclosure process.

Zebrocy is a malware used by APT28 (also known as Sofacy), which was reported by multiple security firms[1][2][3][4][5][6] in the last two years.

Finally, our investigation concluded that the attack started on 5 August and targeted at least a government entity located in the Middle East. However, it is highly likely that NATO members also observed the same attack.

Microsoft today said that it worked with the LLVM and Rust development teams to add support for the Windows Control Flow Guard (CFG) platform security feature into the Clang and rustc compilers.

CFG is designed to block malicious code from changing the default control flaw of Windows programs, it extends other exploitation mitigation tech like /GS (Buffer Security Check)Data Execution Prevention (DEP), and Address Space Layout Randomization (ASLR), and it makes it more difficult to run arbitrary code by exploiting memory bugs such as buffer overflows.

CFG was first released with the Windows 8.1 KB3000850 update in November 2014 and is available today on all Windows 10 devices, with the Windows kernel now compiled with CFG support since Windows 10 Creators Update (Windows 10, version 1703).
