What is Efdc ransomware
Efdc is a new variant of STOP (Djvu) ransomware. Efdc may end up on a computer after a user installs some pirated software or opens a file downloaded from an untrustworthy source. Efdc encrypts users’ files and appends .efdc extension to those files. The ransomware also leaves ransom notes called _readme.txt with the users’ unique ID, the ransomware developers’ contact information and the amount of ransom to pay for decryption.
