: Communication with remote servers to retrieve RSA public keys for file encryption. 4. Mitigation and Defense

: Often delivered via a PowerShell stager (e.g., Roduk or Polock ) that downloads Base64-encoded bytes and stores them in memory. Injection Process :

The payload ( reflect.dll ) is injected into a target process, such as C:\Windows\explorer.exe . : Once active, it typically: reflect.dll

: Use Endpoint Detection and Response (EDR) tools to monitor for Cross-Process Injection , where a process writes to the memory of another.

Malware using reflect.dll typically employs "fileless" execution methods to evade signature-based detection. By loading the payload directly into a legitimate process's memory (like explorer.exe ), the attacker bypasses the need for the file to ever touch the disk in its final executable form. : Communication with remote servers to retrieve RSA

: Log and monitor PowerShell execution for common obfuscation flags like -EncodedCommand or -enc .

Security researchers often identify this threat through the following file paths and behaviors: Injection Process : The payload ( reflect
