Welcome to your secure FlokiNET C2 Server!
╔═══════════════════════════════════════════════╗
║ OPERATIONAL SECURITY ║
║ ║
║ This server has enhanced security features ║
║ including hardened SSH, Tor routing, and ║
║ zero-logs configuration. ║
╚═══════════════════════════════════════════════╝
The following tools and utilities have been installed:
Apt-Installed Tools:
--------------------
- git, wget, curl, unzip
- python3-pip, python3-venv, pipx
- tmux, nmap, tcpdump, hydra, john, hashcat
- sqlmap, gobuster, dirb, enum4linux, dnsenum, seclists, responder
- golang, proxychains, tor, crackmapexec, jq, unzip
- postfix, certbot, opendkim, opendkim-tools
Pipx-Installed Tools:
---------------------
- NetExec: git+https://github.com/Pennyw0rth/NetExec
- TREVORspray: git+https://github.com/blacklanternsecurity/TREVORspray
- impacket: (various network protocols and service tools)
Custom Tools Installed in ~/Tools:
----------------------------------
- SharpCollection: ~/Tools/SharpCollection
- Kerbrute: ~/Tools/Kerbrute
- PEASS-ng: ~/Tools/PEASS-ng
- MailSniper: ~/Tools/MailSniper
- Inveigh: ~/Tools/Inveigh
- Gophish: ~/Tools/gophish (unzipped here)
Other Installed C2 Frameworks:
------------------------------
- Metasploit Framework: system installed (run 'msfconsole')
- Sliver C2: system installed (run 'sliver')
Security Scripts in /opt/c2/:
-----------------------------
- clean-logs.sh: Securely clears all logs on the system
- secure-exit.sh: Perform secure wipe for termination
- serve-beacons.sh: Hosts generated implants for delivery
Also, remember that many reconnaissance and attack tools are now available system-wide due to the apt and pipx installations.
Once your DNS record points to this server's public IP, you can obtain a Let's Encrypt certificate by running:
sudo certbot certonly --non-interactive --agree-tos --email {{ letsencrypt_email }} --standalone -d {{ c2_subdomain }}.{{ domain }}
**IMPORTANT:**
To route traffic through Tor for additional anonymity, prefix commands with 'proxychains':
proxychains curl ifconfig.me
Don't forget to set up a DMARC record for your domain. Update your DNS provider's dashboard to add a TXT record named `_dmarc` with a suitable DMARC policy (e.g., `v=DMARC1; p=reject; rua=mailto:admin@{{ domain }}; ruf=mailto:admin@{{ domain }}; pct=100`). This ensures better email deliverability and security for your domain.
