Locker Ransomware Author Allegedly Releases Database Dump of Private Keys
Allegedly, the author of the “Locker” ransomware has uploaded a dump of the C2 server database, releasing private keys of infected hosts worldwide to the public. The “author” claims that the release was a mistake, that no further keys will be utilized for encryption, and that automatic decryption of all affected hosts will begin on June 2nd.

Hi, I am the author of the Locker ransomware and I‘m very sorry about that 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. hxxps://mega.co.nz/#!W85whbSb!kAb-5VS1Gf20zYziUOgMOaYWDsI87o4QHJBqJiOW6Z4 Automatic decryption will start on 2nd of june at midnight. @devs, as you might be aware the private key is used in the RSACryptoServiceProvider class .net and files are encrypted with AES-256 bit using the RijndaelManaged class. This is the structure of the encrypted files: - 32 bit integer, header length - byte array, header (length is previous int) *decrypt byte array using RSA & private key. Decrypted byte array contains: - 32 bit integer, IV length - byte array, IV (length is in previous int) - 32 bit integer, key length - byte array, Key (length is in previous int) - rest of the data is the actual file which can be decrypted using Rijndaelmanaged and the IV and Key Again sorry for all the trouble.
