Comprehensive persistence tradecraft for authorized red team engagements covering Windows and Linux mechanisms. Windows techniques include registry Run/RunOnce keys, scheduled tasks, WMI event subscriptions, DLL search order hijacking, COM object hijacking, Startup folder drops, service creation, Security Support Provider (SSP) DLL injection, and Active Directory persistence (AdminSDHolder abuse, DCShadow, Golden Ticket, Silver Ticket, Skeleton Key, SID History injection). Linux techniques…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Offensive Persistence Persistence ensures your access survives reboots, password changes, and routine maintenance. You plant mechanisms that re-establish a session or re-execute your payload without requiring a new initial compromise. The choice of persistence technique depends on your privilege level, the target operating system, the engagement scope, and the detection risk you can tolerate. This skill covers both Windows and Linux persistence methods, from simple registry keys to domain-level Active Directory backdoors. Every technique here assumes you already have code execution on the target. Apply these in authorized engagements only. ## Quick Workflow 1. Assess your current privilege level (user-level vs admin/root vs domain admin). 2. Identify the target OS version and security controls in place. 3. Select a persistence mechanism matching your access level and stealth needs. 4. Validate the persistence survives a reboot or logoff event. 5. Document the exact mechanism and location for cleanup during engagement close. 6. Layer multiple persistence methods at different privilege levels when scope allows. …

How to install
mdr add snailsploit/claude-red/offensive-persistence@sha256:9b571dd2288f56dbThe line at the top of this page pins the label git:20260825.f7a0553, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
