Attackers repeatedly changed the files that AOMEI Backupper fetches from the vendor's own update servers, in windows of five to ten minutes at a time between May and July 2026, so that any copy of the Windows backup program that checked for an update during one of those windows would download and run a backdoor.

Nothing in the software was exploited. There was no vulnerability, and no user action was needed beyond having the program installed and running, according to ManageEngine's lab. The attacker only had to change two text files on the server for a few minutes.

DAMN ADAPTIX C2 in action! Clearly sophistication was fairly high for this campaign.
