Another Confluence Bites the Dust: Falling to ELPACO-team Ransomware

In June 2024 an unpatched Atlassian Confluence server was exploited via CVE-2023-22527 to deliver Metasploit loaders and Meterpreter, enabling the attacker to install AnyDesk for remote access, escalate to SYSTEM (named pipe/RPCSS impersonation), harvest credentials with Mimikatz/Impacket/ProcessHacker, obtain Domain Admin access, laterally move via WMIXEC and RDP, and ultimately deploy ELPACO-team (a Mimic variant) ransomware to backup and file servers about 62 hours after initial access; the report includes timeline, forensic artifacts, IoCs (IPs, filenames, hashes), detection rules, and mitigation/recovery observations.
