# Signature-Base

signature-base is the signature database for my scanners LOKI and THOR Lite

## 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](https://github.com/Neo23x0/Loki) or [THOR Lite](https://www.nextron-systems.com/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](https://www.nextron-systems.com/2018/12/21/yara-rule-sets-and-rule-feed/), which contains better and 20 times the number of rules.
