Signature-Base

Signature-Base is the YARA signature and IOC database for our scanners LOKI and THOR Lite

Focus of Signature-Base

  1. High quality YARA rules and IOCs with minimal false positives
  2. Clear structure
  3. Consistent rule format

Directory Structure

  • iocs - Simple IOC files (CSV)
  • yara - YARA rules
  • threatintel - Threat Intel API Receiver (MISP, OTX)
  • misc - Other input files (not IOCs or signatures)

External Variables in YARA Rules

Using the YARA rules in a tool other than LOKI or THOR Lite will cause errors stating an undefined identifier. The rules that make use of external variables have been moved to the following 4 rule set files:

  • ./yara/generic_anomalies.yar
  • ./yara/general_cloaking.yar
  • ./yara/thor_inverse_matches.yar
  • ./yara/yara_mixed_ext_vars.yar

High Quality YARA Rules Feed

If you liked my rules, please check our commercial rule set and rule feed service, which contains better and 20 times the number of rules.
