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.
