MIGLOGCLEANER

MIGLOGCLEANER is an ELF log-wiping utility for Linux and Unix-based systems. The provided content states it can wipe logs or remove certain strings from logs, and that it has been publicly available on GitHub. It was observed in use by UNC2891 as part of a broader Linux/Unix/Solaris-focused toolkit associated with stealthy post-compromise operations and financial fraud activity, including attacks against ATM switching and related infrastructure. In reporting cited in the content, MIGLOGCLEANER is also referenced as LOGBLEACH/MIGLOGCLEANER, indicating it functions as a log cleaner/wiper used to reduce forensic visibility after intrusion. No specific standalone indicators of compromise for MIGLOGCLEANER are provided in the content.
