UltraDeCrypter (updated Dec 2016) - Decryption Steps Included

UltraDeCrypter Removal Guide

What is UltraDeCrypter?

UltraDeCrypter – the tool that no one needs since free CryptXXX decryption tools were released

In June 2016, the cyber security experts have found that CryptXXX virus has changed the user interface (UI) design on its payment site as well as renamed its decryptor to UltraDeCrypter[1]. After a thorough investigation, the specialists have confirmed that actors behind CryptXXX ransomware project[2] are the same ones who are responsible for UltraCrypter ransomware attacks. Apart from a different name, the viruses are entirely identical. They both spread through Angler Exploit Kit, which searches the system for vulnerabilities and uses them to stealthily install the malicious software on the victim’s computer. Once on the system, the virus starts encrypting containing files using an RSA-4096 algorithm[3]. During the encryption, public and private keys are created, first for locking the files and the second, for decrypting them. Unfortunately, the cyber criminals have the private key under their control and demand the victims to pay around 1.2 BitCoin ($567.6 USD) if they want to be able to access their files again. It is not advisable to make any transactions to the accounts of the cyber criminals because that is exactly what they are waiting for. By paying up, you will only encourage the crooks to become even more greedy and continue creating malicious software. Therefore, the security professionals recommend the infected computer users to remove UltraCrypter as soon as possible.

It is understandable that data recovery after the UltraCrypter attack will be the biggest priority among the virus victims. Unfortunately, there is little chance to restore the system to its original state. The criminals will encourage you to purchase the UltraDeCrypter tool, which will supposedly solve all of your problems, but as we already mentioned, it is not safe to collaborate with the criminals on any level. In such a case it is beneficial to have backup copies of your files, but if you do not have such, just use CryptXXX decrypter[4]. This utility helps to recover all of the files. You must remember that before making any recovery steps, you should take care of the full UltraCrypter removal. Otherwise, your decrypted files may soon be locked again. You should use only the reliable anti-malware tools, such as FortectIntego for this purpose.

Updated on December 23, 2016. CryptXXX ransomware seems to be booming at the moment, or at least its developers are very obstinate and refuse to give up in a fight with reverse-malware engineers. Malware researchers are a step forward comparing to CryptXXX virus’ authors because they managed to build even three decryption tools for the first, second, and third CryptXXX version. Surprisingly, authors of this malicious virus feel desperate and seek to collect at least a few ransoms, and recently they crafted a pop-up message to appear in all payment websites, suggesting a Christmas discount and a new price for UltraDeCrypter – 0.5 Bitcoin instead of the previous price of 1.2 Bitcoin. However, at the moment victims can recover corrupted files for free using RannohDecryptor.

Prevent ransomware attacks

The best way to avoid paying for your own files is to equip your computer with a reliable antivirus software, which would warn you about dangerous sites or downloads through which you may have your computer infected. However, security specialists suggest that one layer of protection is never enough[5]. Additionally, you should obtain a powerful firewall and keep an eye on the newest system updates to make sure your system fits the newest security standards. You should also store additional copies of your files on some external storage. This way, in a case of ransomware attack, you will not have to worry about losing your files and safely proceed with the virus removal. Just make sure you choose a reliable software for the job.

Remove UltraDecrypter if you obtained it

UltraDeCrypter removal will not help you to fix your computer as it is not a virus itself. You will have to remove the virus to which it is related first. CryptXXX and Ultra Crypter are the same virus and so they offer the same decrypter, so only a reliable anti-malware software will be able to identify which of these viruses have infected your computer. Virus removal utility will also find all the malicious virus components on your computer and terminate them immediately. However, if, for some reason, you will notice that the antivirus is unable to initiate, or the scan fails, it might be that the virus is blocking the process. If such situation occurs, do not get flustered, disconnect your computer and look up CryptXXX and UltraCrypter viruses on our site. Follow the instructions provided at the end of the virus descriptions closely and then run a scan again.

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
