Anti-Malware — entry 006 of 15
MalShare
MalShare is a community-run, free public malware sample repository: registered users pull hash lists, per-sample metadata, and the raw binaries themselves through a single api.php endpoint, or upload their own finds back to the pool. A live GET against that endpoint with an invalid key returned a plain-text "user specified in api_key GET variable does not exist" error rather than any CORS header, reconfirming API-key auth over HTTPS and reconfirming cors as no. Standard registered keys are free and capped around 2,000 calls a day, a limit MalShare says it will raise on request.
