      This one is kinda interesting. Uses a .ISO file (Defender and possibly others allowlist by default, but Win10 opens natively), inside there's a .exe which is too large for Defender to scan. C2 is via Apple's push infrastructure. https://www.virustotal.com/gui/file/83f99f42880fcbbbe6e810aa8bc498a4318e27fcfb86301c4bd305be9379234e/detection … https://twitter.com/bcrypt/status/1420471176137113601 …

      This isn't RedLine, it's another infostealer called ArechClient. Write-up from Trend: https://www.trendmicro.com/en_us/research/21/b/finding-multi-step-obfuscated-malware.html … It uses RegAsm to load the eventual payload: https://www.virustotal.com/gui/file/059ea6ee0994314502c421d6bab2841593ecaa287538f06a6e2b039fcb95ba6b/detection …

      My pleasure - to help ID the malware, I used @James_inthe_box's excellent Git:https://github.com/silence-is-best/c2db#arechclient2 …
