W_bm_s_03.7z
: Hardcoded Command & Control (C2) addresses found in process memory.
In these specific training sets, analysts are usually looking for:
: Prefetch files or Shellbags that show which programs the "suspect" executed. w_bm_s_03.7z
Use tools like file (Linux) or to identify the extracted file type (e.g., a .raw memory dump or a .vmdk virtual disk). Artifact Extraction :
Calculate the MD5 or SHA-256 hash of the .7z file before and after extraction to ensure the evidence hasn't been tampered with. : : Hardcoded Command & Control (C2) addresses found
: If it's a memory dump, use Volatility 3 to list running processes ( windows.pslist ), network connections ( windows.netscan ), or injected code ( windows.malfind ).
While the exact contents can vary based on the specific version of the challenge, archives following this naming convention (e.g., w_bm_s_03 ) usually represent a or a Disk Image segment. Prefix ( w ) : Often denotes a Windows-based system. Artifact Extraction : Calculate the MD5 or SHA-256
Decompress the archive (some challenge files require a password, often provided in the challenge description or "infected"). :
