MalwareMustDie, NPO[1][2] is a whitehat security research workgroup that was launched in August 2012.

MalwareMustDie is a registered nonprofit organization as a medium for IT professionals and security researchers gathered to form a work flow to reduce malware infection in the internet.

[59] Recent activity of the team still can be seen in several noted threat disclosures, for example, the "FHAPPI" state-sponsored malware attack,[60] the finding of first ARC processor malware,[61][62][63] and "Strudel" threat analysis (credential stealing scheme).

MalwareMustDie compares their mission to the Crusades, emphasizing the importance of fighting online threats out of a sense of moral duty.
