This analysis details a malicious campaign dubbed 'FHAPPI' by the researcher, which utilized compromised Geocities Japan accounts to host malware payloads. The campaign leveraged VBScript and PowerShell scripts to execute encoded commands, ultimately delivering the Poison Ivy remote access trojan (RAT) through process injection. The researcher provides a detailed reverse engineering analysis of the malware components, including decoding multiple layers of obfuscation, identifying the use of PowerSploit code, and tracing the malware's behavior and network communications. The report concludes by attributing the campaign to the threat actor APT10 and providing relevant indicators of compromise.
