# Havoc C2 Framework (Dev Branch)
|

|

This is an installation of the Havoc C2 Framework using the **dev branch** with enhanced randomization.
|
||||
|
||||
## Important Information
|
||||
|
||||
- **Admin User:** $ADMIN_USER
|
||||
- **Admin Password:** $ADMIN_PASS
|
||||
- **Teamserver Port:** $TEAMSERVER_PORT
|
||||
- **Config File:** $HAVOC_CONFIG_FILE
|
||||
|
||||
## Starting the Server
|
||||
|
||||
The server can be started with:
|
||||
|
||||
\`\`\`
|
||||
$HAVOC_DIR/Teamserver/havoc server -d
|
||||
\`\`\`
|
||||
|
||||
## Implant Mutation
|
||||
|
||||
To randomize implant signatures and avoid detection, use the implant mutator:
|
||||
|
||||
\`\`\`
|
||||
havoc-mutate # Run manual mutation
|
||||
havoc-mutate --auto-schedule # Setup automated mutations
|
||||
havoc-mutate --config-only # Only modify configuration values
|
||||
\`\`\`
|
||||
|
||||
The system is configured to automatically mutate implants every 12 hours via systemd timer.
|
||||
|
||||
## Enhanced Security Features
|
||||
|
||||
This installation includes:
|
||||
- Shellcode randomization
|
||||
- Implant signature randomization
|
||||
- Memory allocation/execution randomization
|
||||
- Stack spoofing and sleep masking
|
||||
- Indirect syscalls
|
||||
- Binary obfuscation techniques
|
||||
- Automated implant mutation
