## What it is
A community-maintained repository of YARA rules for malware and threat detection, organized into categories like anti-debug/anti-VM, CVEs, crypto, exploit kits, and malicious documents. It provides a curated, up-to-date ruleset that can be used with YARA 3.0+ for scanning files and memory.

## Use cases
- scan files for malware with yara rules
- detect malicious pdf and office documents
- identify exploit kits in web traffic samples
- find crypto algorithm signatures in binaries
- detect anti-debug and anti-vm techniques in samples
- match known CVE indicators in files

## When to choose
- you need a broad, community-curated YARA ruleset to start malware hunting
- you want categorized signatures for documents, exploit kits, and CVEs
- you need an open-source (GPLv2) rules collection for security research

## When to avoid
- you need real-time threat intel feeds with SLAs
- you require mobile malware rules relying on the deprecated Androguard module
- you need a commercial support-backed detection product

## Facets
- artifact type: dataset
- maturity: maintenance
- function: security, vulnerability-scanning
- domain: security, developer-tools
- platform: cross-platform, cli
- tags: yara, malware-detection, signatures, threat-intelligence, ruleset
