Looking forward to presenting at the AUSCert conference tomorrow on the Gold Coast main stage. Putting together a high level talk about denying attackers moves to win the game in-line with the conference theme has been fun.

No detections on this one pretending to be mstsc.exe and signed by "Tencent Technology (Shenzhen)". virustotal.com/gui/file/8bfb…

I've put up a blog on the DigiCert incident as well as the Microsoft definition false positive. This includes some analysis and VT links to samples that have actually been signed by the compromised certificates. airlockdigital.com/airlock-b…

Does anyone know what source of malware samples for the path D:\auto_black_abuse is to VT? Is this a vendor sample share feed?

Signature-based control breaks down with agentic AI. Block one path → it tries another. Different method. Same outcome. That’s why control needs to be on the endpoint - and focus on capability AND execution. My blog (with videos) here: airlockdigital.com/airlock-b…

Yeah okay, that's pretty wild. The attackers only replaced the zip downloads on the site. At first look the included executables are signed, but malware is the additional CRYPTBASE.dll which would side loaded on app startup

CPUID via winget is still legitimate but assuming the attackers control the site they could replace the binary anytime.

We have two choices: We can broadly adopt app control, or we can continue to get our asses kicked. If we keep persisting in choosing the latter course, the only real question is whether the kicking will be about the same as now or whether it will get substantially worse.
Happy Saturday! Exposed attack surface on the internet has been shifting from legacy appliances and Windows boxes directly on the internet into cloud for years now (Thanks Citrix, Fortinet, MoveIt, etc). The excitement around LLMs findin vulnerabilities and the incoming apocalypse is legitimate, however directly exposed attack surface has been decreasing(Thanks App proxy, zscaler, etc) and now you have more eyes on what was already a shrinking target. Bugs found on the cloud side have a shorter life and once identified, generally patched for everyone at once. Down the line from that you can certainly use LLMs to go after endpoint bugs in Microsoft where you generally lack source and it requires a higher level of human directed iteration, on top of dealing with EDR/AV if your target is enterprise. No doubt people can iterate faster and find more bugs, I've found a ton of these personally, but many bugs have limited to no real world impact. Configurations you won't see in the wild, code paths you can't reach without auth you don't have, features that are off by default. Overlooked in all of this is the ease at which you can reverse and dismantle security products, many of which are forced into design choices by the OS, or into exclusions to avoid drowning clients in false positives. Things like extracting the local ML models from products isn't a big leap these days. It certainly makes the case for application control being a bigger priority going forward, even if it doesn't make for a great funding pitch.

Created a short demo showing a simulation of modern day ClickOnce Assembly sideload phishing campaigns we’re seeing targeting finance orgs in the wild. Comments showing ⁦⁦@AirlockDigital⁩ app control on same method in comments.

With @AirlockDigital in Enforcement mode with .NET Assembly reflection protection enabled. It’s also possible to only allow clickonce applications by domain.
