extracting-config-from-a-running-sample

Extracts an embedded malware configuration (C2 hosts, ports, campaign IDs, keys) from a process memory dump by locating decrypted config structures and decoding common obfuscation layers. Activates for requests to extract malware config from a memory dump, recover C2 settings from a running sample, or decode an in-memory configuration block.

Extracting Config From a Running Sample

When to Use

  • You have a process memory dump of a detonated sample whose config is decrypted in memory.
  • You need to recover C2 endpoints, ports, campaign/botnet IDs, mutexes, and keys.

Do not use this to detonate the sample — it consumes a dump already captured in an isolated sandbox. For static-only config decryption, use the dedicated config-decryptor workflow.

Prerequisites

  • A process memory dump (.dmp/raw region) captured after the config was decrypted.

Safety & Handling

  • Treat the dump as malicious data; read it inertly and defang recovered endpoints.

Workflow

Step 1: Hunt config indicators

python scripts/analyst.py hunt process.dmp

Scans for URLs, IPv4:port pairs, mutex-like tokens, base64 blobs, and printable key/value candidates in decrypted regions.

Step 2: Decode obfuscation layers

For candidate blobs, try common transforms (single-byte XOR brute force, base64) and re-scan the decoded output for endpoints.

Step 3: Structure and validate the config

Assemble recovered fields into a structured config and sanity-check (valid hosts, plausible ports, consistent campaign IDs).

Step 4: Defang and report

Defang hosts/URLs and document the offsets where the config was recovered.

Validation

  • Recovered endpoints are real, parseable hosts/ports — not random byte noise.
  • XOR/base64 decode is confirmed by the decoded output containing new endpoints/strings.
  • The final config is defanged before sharing.

Pitfalls

  • Mistaking unrelated in-memory URLs (browser, OS) for C2 — corroborate with the sample's region.
  • Single-byte XOR brute force producing coincidental strings; require multiple corroborating hits.
  • Reporting raw, live C2 endpoints without defanging.
