Locker Ransomware Author Allegedly Releases Database Dump of Private Keys

Pierluigi Paganini May 30, 2015

Allegedly, the author of the “Locker” ransomware has uploaded a dump of the C2 server database, releasing private keys of infected hosts to the public.

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.

This is the post made by the alleged author, uploaded to [url=http://pastebin.com/1WZGqrUH] on 05/30/2015 .

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.

Based on a brief analysis, the file seems non-malicious and does contain a large quantity of RSA keys.
The CSV file contains Bitcoin addresses and RSA keys.

Open at your own risk, until further analyses are performed.

 

UPDATE May 31th, 2015

Nathan Scott, an experienced programmer who can often be found developing and releasing decryption utilities and other security-related tools on BleepingComputer.com, has created adecrytpion utility for theLockerransomware.

The decryption utility can be downloaded from the below URL:
