The Malware Analysis Space post examines a Kimsuky/APT43 PowerShell sample associated with ASEC reporting on forceCopy malware used in spear phishing. The sample, identified by MD5 1e9d94d88fdac3c4a0a47a3a1d07e329, uses heavy obfuscation with reversed string ranges, Base64 decoding, and dynamic PowerShell execution. After deobfuscation, the script shows Google Drive interaction, embedded access token material, folder and client parameters, script execution, output handling, and upload behavior. The author could not recover the referenced tmps4.ps1 payload, but the available code indicates a browser-information theft or follow-on malware chain aimed at victim data collection.
