We've uploaded a preview of our Advanced Malware Binary Triage course where we analyze an example x86-64 binary in Binary Ninja and compare it to x86. Enjoy!
The campaign seems most similar to the classic "Recipe Lister", the original TamperedChef, analyzed by @luke92881 , @InvokeReversing 's community, Dingusxmcgee, others https://t.co/ktTyCT9FXc
Based on the certificate usage, it aligns: again with US, UK, and UA certificates.
7/9
We've uploaded our live stream from October 16th where we analyzed a Rust loader that uses indirect syscall resolution, AES decryption, ETW patching and multiple unpacking steps to load and execute NWHStealer. Enjoy!
We're also seeing fake "RDP OfficeX Manager" and "PLClean Master" as a part of the same campaign. IOCs (including 2FA apps):

Analysts @HuntressLabs have been seeing an uptick of malicious MFA apps from the Microsoft Store the last few days. In some cases, they're being delivered via tech support scams through Teams, in others via malvertizing.
We've been digging into it, and hopefully we'll have more info soon.
We've uploaded our live stream from late September where we explored Detection Engineering with Yara using Assemblyline, CAPEv2, bindiff and mquery. We go over packer detection, unpacked file detection and writing dependable rules that will outlast changes by the malware author and recompilations. Enjoy!
It was an honour to speak with Pablo on the debut episode of the Polo Cyber podcast. We spoke about my early beginnings, career, reverse engineering, malware analysis and Invoke RE. Hope you enjoy it!
