This week's newsletter is hot off the press, get it here: https://opalsec.substack.com/p/soc-goulash-weekend-wrap-up-b16

The #ESXiArgs escapades have gone from bad to okay and back to bad again, after attackers revised their encryption routine to bypass CISA's recovery script, and launched a 2nd wave of attacks that resulted in the reinfection of hundreds of hosts. Worst yet - we don't know how they're doing it, as the OpenSLP service (believed to be their method of ingress) has been disabled in a number of reported infections.

PowerShell isn't dead - The DFIR Report published their analysis of an apparent attack by Iran's Oilrig/APT34, whose initial infection relied exclusively on PowerShell and remained undetected for a significant period of time.

Proofpoint have unveiled #TA866, a savvy threat group that leverages the 404 Traffic Distribution System and little known AutoHotKey scripting language to cherry pick their targets.

#RedTeam members might find the BokuLoader Reflective Loader for #CobaltStrike useful in their next engagements, as well as #LocalPotato - the latest PrivEsc technique to join the Potato family.

#BlueTeam - check out a list of resources that popped up last week to help analyse #ASyncRAT malware and infections, as well as some helpful how-tos on hunting IIS backdoors and DLL abuse techniques

Happy reading, and happy Monday!
