100 Days of YARA (#100DaysofYARA)

An annual YARA challenge started by Greg Lesnewich in 2022, inspired by #100DaysOfCode and taking place in the first 100 days of the year. The goal is to contribute daily to the YARA community through rule creation, source code contributions, or generally teaching/help your colleagues. Other key contributors include Wesley Shields and Steve Miller. For a list of all participants in the first two years of the challenge, see our Twitter List.
