Remove Ultracode Ransomware and Restore .ultracode Files

Created around three years ago, Ultracode ransomware is still causing infections. It seems that it locks the user files adding .ultracode file extension to them. The ransomware then leaves a ransom message pointing out the user with “instructions” on how to pay off the cyber crooks in return for the decryption of the data. However, it is strongly advisable not to and try other methods to restore your files instead.

Ultracode Ransomware – How Does It Spread?

This old ransomware is the perfect example that crypto-malware can still spread with the same proportions as a new one. All that is needed is good obfuscation of the payload and a good Trojan horse to drop it onto the computer. These may usually distribute either via drive-by downloads caused by malicious web links or archived attachments in spam email. Such spam mails may pretend to be a legitimate service assisting users with non-existent problems’ like:

  • Their account has been suspended.
  • They have an incoming transfer.
  • They have been banned from a service.

Either way, users should beware, and we strongly advise using malicious URL blocking as well as external mail software that has spam blocking enabled to prevent such attacks in the future.

Ultracode Ransomware In Detail

This ransomware may act in two stages:

Stage 1: Infection and Encryption

Once on the user PC, the ransomware may create one or more files of the following file formats:

  • .dll, .exe, .tmp

The file names may resemble a program, a game or have completely random names:

  • 230rh190h23.exe
  • ET5557293774.dll
  • Notepad.exe
  • steamapps.tmp

In addition to that, the malware may create a registry entry so that the payload starts when you start Windows. The key targeted for that is:

  • HKLM\Software\Microsoft\Windows\CurrentVersion\Run

After doing so, the ransomware may start scanning all of the important user data and encrypt the files adding a .ultracode extension to them:


Stage 2: Notifying the User

Ultracode adds a ransom note in the form of a text file, named “HOW TO DECRYPT FILES.txt”. It has the below-mentioned scareware instructions. Such instructions aim to scare away users into paying ransom money to cyber crooks by extorting them with a deadline and conditions.
