UltraDeCrypter Ransomware DOES NOT Decrypt Your Files
KnowBe4 gets regular calls from system admins who found us on the internet that are between a rock and a hard place. Backups failed and they have no way to revert to normal files. Worse, there is now a ransomware strain called UltraDeCrypter which simply does not deliver the unencryption routines after you pay. We have tried this twice, and two out of two they took the money and ran.
I'm sure that these crooks are incurring the wrath of the other criminal players in the ransomware racket, but in the meantime if you see this screen and have no backups, you are truly hosed. Above is what the ransomware looks like that does NOT post the decryption file once you pay.
