LinPeek - Linux Post-Exploitation Toolkit

---

LinPeek is a comprehensive post-exploitation toolkit for Linux systems, designed for security professionals to assess system security, identify privilege escalation vectors, harvest credentials, and establish persistence.

Features

• System Enumeration

  • SUID binary detection with GTFOBins integration
  • Container/Docker environment detection
  • Cron job analysis
  • Host environment detection (WSL, VM, etc.)

• Privilege Escalation

  • Kernel exploit suggester
  • Sudo permission checker
  • Writable system file detection

• Credential Harvesting

  • /proc filesystem scanning for secrets
  • Shell history analysis
  • SSH key discovery

• Persistence

  • Multiple persistence mechanism installation
  • Log cleaning capabilities

Installation

git clone https://github.com/shellkraft/linpeek.git
cd LinPeek
pip install -r requirements.txt

---

Usage

python linpeek.py [options]
python linpeek.py --all --report linpeek-report.json

Options:

--enum: Basic system enumeration

--privesc: Privilege escalation checks

--creds: Credential harvesting

--persist: Persistence module

--all: Run enumeration, privilege escalation, and credential modules in one pass

--skip-gtfo-update: Skip the GTFOBins update prompt/check during enumeration

--report <path>: Export structured findings to a file

--report-format {json,text}: Choose report output format (default: json)

Reporting Improvements

LinPeek now aggregates findings across modules, assigns severities, prints an end-of-run summary table, and can export a structured JSON or text report for later review or automation.
