CryptFile2 Ransomware Returns in High Volume URL Campaigns

概要

Proofpoint researchers originally discovered the CryptFIle2 ransomware in March. At the time, it was spreading via EKs; however, beginning on August 3, 2016, we detected the first large-scale email campaign distributing CryptFIle2, allowing a degree of targeting not generally possible with EKs. This ongoing campaign appears to be targeting primarily state and local government agencies and educational institutions in the United States.
