In late October 2024, a government website was discovered hosting malware targeting multiple government entities. The malware, dubbed TOUGHPROGRESS, utilized Google Calendar for command and control. Attributed to APT41, a PRC-based actor, the campaign targeted global organizations in various sectors. The malware infection chain involved three modules: PLUSDROP, PLUSINJECT, and TOUGHPROGRESS, employing stealth and evasion techniques. TOUGHPROGRESS used encrypted Calendar events for communication. Google Threat Intelligence Group disrupted the campaign by developing custom fingerprints, terminating attacker-controlled infrastructure, and updating Safe Browsing. APT41 has been observed using free web hosting tools and URL shorteners for malware distribution since August 2024.
