There is no timetable for when or if a private key for an OFFLINE ID will be recovered and shared with Emsisoft and no announcement by Emsisoft when they are recovered due to victim confidentiality. For now, the only other alternative to paying the ransom, is to backup/save your encrypted data as is and wait for possible future recovery of a private key for an OFFLINE ID. Thereafter, any files encrypted by the OFFLINE KEY for that variant can be recovered using the Emsisoft Decryptor. When and if the private key for any new variant is obtained it will be pushed to the Emsisoft server and automatically added to the decryptor. ** If there is no OFFLINE ID for the variant you are dealing with, we cannot help you unless a private key is retrieved and provided to Emsisoft. The Emsisoft Decryptor will also tell you if your files are decryptable, whether you're dealing with an "old" or "new" variant of STOP/Djvu, and whether your ID is ONLINE or OFFLINE.Įmsisoft has obtained and uploaded to their server OFFLINE IDs for many (but not all) of the new STOP (Djvu) variants as noted in Post #9297 and elsewhere in the support topic.

ONLINE KEYS are unique for each victim and randomly generated in a secure manner with unbreakable encryption. If infected with an ONLINE KEY, decryption is impossible without the victim’s specific private key. In regards to new variants of STOP (Djvu) cryption of data requires an OFFLINE ID with corresponding private key. Emsisoft can only get a private key for OFFLINE IDs AFTER a victim has PAID the ransom, receives a key and provides it to them.
