Ransomware creator apologizes for 'sleeper' attack, releases decryption keys

Last week, a new strain of ransomware called Locker was activated after having been sitting silently on infected PCs. Security firm KnowBe4 called Locker a "sleeper" campaign that, when the malware's creator "woke it up," encrypted the infected devices' files and charged roughly $24 in exchange for the decryption keys.

This week, an internet user claiming to be the creator of Locker publicly apologized for the campaign and appears to have released the decryption keys for all the devices that fell victim to it, KnowBe4 reported in an alert issued today. Locker's creator released this message in a PasteBin post:

"I am the author of the Locker ransomware and I'm very sorry about that [sic] has happened. It was never my intention to release this. I uploaded the database to mega.co.nz containing 'bitcoin address, public key, private key' as CSV. This is a dump of the complete database and most of the keys weren't even used. All distribution of new keys has been stopped."
