The Google Threat Intelligence Group (GTIG) reports that attackers compromised AOMEI Technology’s update and notification infrastructure in a campaign investigated between April and July. AOMEI Backupper is backup software that the company says is used by more than 100 million people worldwide. It lets users back up files, copy entire drives, and recover data if something goes wrong with their PC. The attackers briefly altered AOMEI’s update and notification infrastructure to make customers’…

[This is a Guest Diary by Zachary Norwood, an ISC intern as part of the SANS.edu BACS program] Crypto mining malware has been active and spreading across the internet for quite some time now. Moreover, the DShield honeypot picked up a worm that self-propagates through a plethora of means. One of them is stealing SSH keys after it gains access to a system. Furthermore, it also leverages a rootkit to maintain access to infected systems. One would hope that threat actors would have moved on past…

Years ago I wrote diary entries about VBA code stored inside AutoCAD drawing files (.dwg). In a nutshell: the VBA code is stored inside an OLE file, that is embedded inside the DWG file. You can do a brute-force search for the embedded OLE file, or you can follow a pointer inside the header of the DWG file. I wrote a small Python script (autocad.py) for this second case. It looks at a 32-bit pointer at position 0x24 inside the DWG file. This points to a 16-byte long header, followed by the…

“AI-analysis evasion” encapsulates the real-world techniques malware authors are developing in attempt to obstruct or defeat any layers of automated AI analysis. This technique is cheap to add but inconsistently impactful — the best techniques steered the outcome in the attacker’s favor in about 35% of test runs. Further, it must always be plaintext and therefore is always detectable. The operators are not wrong to assume AI tools are in the analysis pipeline, but the answer is not to remove…
