: Ensure systems are patched against known vulnerabilities (e.g., WebLogic exploits) often used to deliver these loaders.
: Disabling of "System Restore" and "Automatic Startup Repair".
: If you are using legitimate backup software like Macrium Reflect , ensure you are running the latest version to avoid DLL loading vulnerabilities . The Evolution Of Evasion - Culbert Report
: Often delivered via a PowerShell stager (e.g., Roduk or Polock ) that downloads Base64-encoded bytes and stores them in memory. Injection Process :
The stager uses Invoke-Expression to run a reflective loader in memory.
: Log and monitor PowerShell execution for common obfuscation flags like -EncodedCommand or -enc .
: Scans UNC network shares to encrypt data on unmapped drives. 3. Artifacts and Indicators
