Security & OpSec Manual

Operational security principles for Kerberos darknet market. Protect your identity, secure your XMR wallet, avoid common threats.

Common Threats

Core OpSec Principles (Essential)

Compartmentalization

Never reuse identities. Separate clearnet/darknet personas completely. Different usernames, wallets, emails for each market.

XMR Only

Use Monero exclusively. Bitcoin leaves permanent blockchain signatures. Convert BTC → XMR via non-KYC exchanges only.

PGP Everything

Encrypt all communications. Never send sensitive data in plaintext. Verify all PGP fingerprints before trust.

Threat Model (Active 2026)

┌─ Active Threats ──────────────────────────────┐
│ 1. Phishing mirrors (67% of incidents)        │
│ 2. Malicious exit nodes (ISP level)           │
│ 3. Wallet malware (clipboard hijacking)       │
│ 4. Correlation attacks (timing/longtail)      │
│ 5. Social engineering (support scams)         │
└───────────────────────────────────────────────┘

Phishing Defense

  • Copy onion URLs from Official Mirrors only
  • Verify PGP fingerprint matches master key exactly
  • Never click links from Telegram/Discord "support"
  • Check URL length & formatting (kerberosmarketxyz.onion = 19 chars)

  1. Tails OS (USB boot, amnesic, Tor pre-configured)
  2. Whonix (VM isolation, gateway workstation split)
  3. Qubes OS (VM compartmentalization per market)
