Udla Ransomware

Udla Ransomware Description

A threat belonging to the STOP/Djvu family, the Udla Ransomware can cause significant damage to the system it manages to compromise. Ransomware threats are created with the purpose of encrypting the victim's data and leaving it in an unusable state. Typically, they use strong cryptographic algorithms to ensure that the locked files cannot be recovered without assistance from the attackers.

As part of its actions, the Udla Ransomware will modify the names of all locked documents, PDFs, archives, databases and more. The specific file extension used to mark the encrypted data is '.udla.' In addition, a text file named '_readme.txt' will be created on the breached devices. The file will carry a ransom note with instructions from the cybercriminals.

Ransom Note's Overview

The ransom-demanding message left by Udla doesn't deviate from the established STOP/Djvu pattern. The attackers state that to send a decryptor tool and the necessary decryption key victims must pay them a ransom of $980. That initial sum can apparently be brought down by 50% to $490 if the affected users initiate communication with the hackers in the first 72 hours of the Udla Ransomware infection.

Two email addresses that can be used to message the threat actors can be found in the note. The main one is 'support@sysmail.ch,' while 'supportsys@airmail.cc' is relegated to the role of a backup address. Victims are also told that they can attach a single encrypted file to be decrypted for free.
