Locky Locker Ransomware

Locky Locker Ransomware Description

The Locky Locker Ransomware Trojan is a data encryption Trojan that was identified on July 30th, 2018. Computer security researchers alerted that the threat payload may be dropped to machines using free software bundles made with InnoSetup, which is a legitimate tool aimed at software publishers. There are reports indicating that the Locky Locker Ransomware is dropped to regular PCs as 'Facture_25.07.2018_991030.exe,' which downloads two other files on the compromised system. The downloader associated with the Locky Locker Ransomware was observed to drop the following objects to the Temp directory on the primary system drive:

  • %TEMP%\is-7RU1O.tmp\lock.exe — it used to encode the user's data
  • %TEMP%\is-2G302.tmp\Facture_25.07.2018_991030.tmp — contains commands that allow the Trojan to delete its files after it has encrypted the user's data

It should be noted that the Locky Locker Ransomware has nothing to do with the infamous Locky RaaS. The Locky Locker Ransomware is an imposter that tries to use the success of another threat to convince users to pay for a decryptor. The Locky Locker Ransomware may run as 'lock.exe' and remove the Shadow Volume snapshots on Windows. This particular Trojan is very similar to the AutoLocky Ransomware and the Locky Diablo6 Ransomware that imitates the real Locky Ransomware. Infected users may find the '.locky' extension attached to their data and find 'LOCKY-README.txt' on their desktops. For example, 'Manu Pilas - Bella Cia.mp3' is renamed to 'Manu Pilas - Bella Cia.mp3.locky.' The ransom note reads:
