SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires hashlib, json, sys, pathlib, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides a robust workflow to detect and remove infostealer malware, which steals credentials and sensitive data, protecting users from financial loss and identity theft.

Core Features & Use Cases

Custom Hash-Based Detection: Identifies malware by computing SHA-256 hashes and cross-referencing them with public threat intelligence databases like VirusTotal and MalwareBazaar.
Targeted File Scanning: Efficiently searches for suspicious files in high-risk system locations.
Controlled AV Escalation: Uses platform-native antivirus (like Windows Defender) only as a last resort after custom methods are exhausted, with explicit user confirmation.
Use Case: If a user suspects their passwords are being stolen, this Skill can be activated to scan their system, identify potential stealer malware like RedLine or Vidar, and guide the user through safe removal.

Quick Start

Use the infostealer-malware-detector skill to scan the system for suspicious files and check their hashes against VirusTotal.

FAQPage Schema

How do I detect infostealer malware on my system using file hashing?▼

Infostealer malware detection works by computing SHA-256 hashes of files in high-risk locations and cross-referencing them with VirusTotal and MalwareBazaar databases to identify known threats.

Can I scan for stealer malware like RedLine or Vidar without a traditional antivirus?▼

Yes, you can scan for stealer malware by computing custom SHA-256 hashes and verifying them against threat intelligence APIs, using platform-native antivirus only as a controlled escalation fallback with explicit confirmation.

Do I need admin privileges to run a full system malware scan with Python?▼

Admin privileges and Python 3.8+ are required for full system malware scans. This ensures the script can access all high-risk system locations to compute SHA-256 hashes and verify them against threat databases.

What is the best way to remove infostealer malware after detecting suspicious files?▼

The best way to remove infostealer malware is to first identify it via SHA-256 hash cross-checks with MalwareBazaar, then escalate to platform-native antivirus removal with explicit user confirmation if custom methods fail.

Does this malware detection approach work with VirusTotal and MalwareBazaar APIs?▼

Yes, this malware detection approach works with VirusTotal and MalwareBazaar by verifying computed SHA-256 file hashes against their public threat intelligence databases to identify known infostealer signatures.

When should I escalate to platform-native antivirus instead of custom hash checks?▼

You should escalate to platform-native antivirus only after custom SHA-256 hash cross-checks against threat databases are exhausted, requiring explicit user confirmation before triggering the platform-native AV removal process.
