Why Persistence Matters?
Ever felt like a character in The Matrix, fighting off relentless cyber threats in a digital world? As Blue Team defenders, one of the most elusive challenges we face is detecting and eradicating persistent threats on Windows systems. These threats hide like the villain in a thriller movie, ready to strike at the most inconvenient moment.
Enter PersistenceSniper - a PowerShell module designed to make hunting down these threats as seamless as it could get. If you’re a Blue Teamer, Incident Responder, or System Administrator, this tool might just become your best ally.
What is PersistenceSniper?
PersistenceSniper is a powerful yet user-friendly PowerShell module designed to detect malicious persistence techniques on Windows machines. It’s scalable, efficient, and, most importantly, beginner-friendly. While tools like Sysinternals’ Autoruns offer a Swiss Army knife of options, they can be overwhelming for those just starting out. PersistenceSniper provides a focused approach with several unique advantages:
Efficient Threat Detection: Simultaneously scan multiple hosts without deploying additional code.
Standalone Functions: Each detection technique has its own function, making it easy to add or remove capabilities.
Velociraptor Integration: Compatible with the Velociraptor DFIR Framework for comprehensive forensic analysis.
Zero Deployment Hassle: No need to upload code onto target machines, reducing risk and complexity.

Practical Applications: PersistenceSniper in Action
PersistenceSniper can be used both locally and remotely, thanks to its support for PowerShell Remoting. Here’s how to get started:
Scanning Your Local Machine
Running PersistenceSniper on your machine is as easy as firing up your favorite game. Just execute:
Find-AllPersistenceWant to focus on a specific technique? Use the -PersistenceMethod parameter:
Find-AllPersistence -PersistenceMethod RunAndRunOnceRemote Scanning
Remote scanning requires a bit of setup:
Enable PowerShell Remoting on the target machine.
Ensure your user account has administrative privileges.
The target machine should be a Trusted Host.
Find-AllPersistence -ComputerName TestMachine1
Why Choose PersistenceSniper?
PersistenceSniper shines in scenarios where ease of use and efficient scanning are paramount. Imagine a newly deployed system - you can use the IncludeHighFalsePositivesChecks parameter to generate a baseline and feed that into DiffCSV for future scans.
For forensic investigations, PersistenceSniper’s compatibility with Velociraptor is a game-changer. Velociraptor is an advanced digital forensic and incident response platform that complements PersistenceSniper's capabilities. Together, they form a formidable duo for tackling complex incidents.
