Partnership with No More Ransom[edit]

Emsisoft is a member of the No More Ransom project. Headed by the National High Tech Crime Unit of the Netherlands’ police and Europol’s European Cybercrime Centre, the initiative was created to help victims of ransomware recover their data without paying a ransom to cybercriminals.[14]


Emsisoft named in leaked NSA documents

Emsisoft was one of 23 antivirus companies named in National Security Agency (NSA) documents[15] leaked by NSA whistleblower Edward Snowden. Emsisoft found no evidence that the NSA had managed to infiltrate its systems.[16]


In 2016, Emsisoft Chief Research Officer Fabian Wosar cracked many different versions of the Apocalypse ransomware, which resulted in malware authors naming a strain of ransomware after him: Fabiansomware.[17]
