CCleaner compromised to distribute Floxif malware

Version 5.33 of the CCleaner app offered for download between August 15 and September 12 was modified to include the Floxif malware, according to a report published by Cisco Talos a few minutes ago. Floxif is a malware downloader that gathers information about infected systems and sends it back to its C&C server. The malware also had the ability to download and run other binaries, but at the time of writing, there is no evidence that Floxif downloaded additional second-stage payloads on infected hosts.

The malware collected information such as computer name, a list of installed software, a list of running processes, MAC addresses for the first three network interfaces, and unique IDs to identify each computer in part. Researchers noted that the malware only ran on 32-bit systems. The malware also quit execution if the user was not using an administrator account.
