Kerberos Security Guide
OpSec & XMR Safety - 2026

PGP Setup Guide

Kerberos darknet market security framework combines military-grade OpSec protocols with Monero blockchain privacy and PGP encryption workflows. This guide details operational security practices proven effective against 2026 darknet threat landscape including chain analysis, correlation attacks, and phishing operations.

Monero XMR Wallet Security

Kerberos exclusively accepts Monero payments due to ring signatures, stealth addresses, and Dandelion++ propagation providing superior privacy over Bitcoin traceable transactions.

Wallet Setup Rules

  • New wallet per vendor/transaction
  • Generate via CLI v0.18.3.4+ official binary
  • 20-word seed → metal backup (NEVER digital)
  • Primary wallet: air-gapped Linux
  • Spend wallet: fresh per purchase

CLI Wallet Commands

./monero-wallet-cli --generate-new-wallet spend_wallet
./monero-wallet-cli --daemon-address node.moneroworld.com:18089
transfer 4adfhv... 0.15

Transaction Safety

  • Confirm 10+ blocks before finalize
  • Churn coins 3x minimum
  • Never reuse receive addresses
  • Remote nodes → VPN → Tor only
  • Check ring size ≥16

Network Layer Protection

Router/Firewall Rules

iptables -A OUTPUT -p tcp --dport 80 -j DROP
iptables -A OUTPUT -p tcp --dport 443 -j DROP
iptables -A OUTPUT -p tcp --dport 53 -j DROP
iptables -t nat -A OUTPUT -p udp --dport 53 -j DNAT

PGP Operational Security

CRITICAL: Never expose private keys to networked systems. Use YubiKey 5 NFC for key storage with touch-to-sign enforcement.

2026 Threat Landscape

Active Attack Vectors

  • Correlation timing attacks (85% success)
  • Bitcoin chain analysis (full tx history)
  • Malicious Tor bridges/exit nodes
  • Browser fingerprinting (Canvas/WebGL)
  • Social engineering (vendor impersonation)

Mitigation Priority

  1. Whonix Workstation + Gateway
  2. Monero CLI wallet (airgapped)
  3. YubiKey PGP smartcard
  4. Tor Browser Safest mode
  5. Metal seed backups
