Rather than indicate the name of their ransomware directly, a cybercriminal gang mentions UltraCrypter as the file recovery tool they peddle to victims.
Online extortionists have rebranded their rapidly propagating CryptXXX ransomware. The recent changes have to do with the look and feel of the Trojan’s user interaction components, as well as the denomination of the decrypt solution. Compared to the commonplace offensive tactics, the perpetrators have come to adopt a reverse approach, where they promote something that appears benign instead of casting the whole malevolent stratagem in the victim’s face. When the attack takes place, the infected person will be told to buy UltraDecrypter, a program that supposedly reinstates all the locked files for 500 USD. The unnamed ransomware – perhaps it makes sense dubbing it ‘UltraCrypter’ – appends the .cryp1 extension to the user’s valuable files.
This malicious software expresses its ransom demands in several files that have the following name pattern: ![victim ID].html, ![victim ID].txt and ![victim ID].bmp. The image edition of ransom notes replaces the desktop wallpaper. The HTML and TXT counterparts will appear in all affected folders. As opposed to the previous variants of CryptXXX, the UltraCrypter spinoff is much more concise in terms of the recovery steps. What it says is the phrase “All your files are encrypted”, followed by a unique ID assigned to the victim, a couple of .onion URLs accessible via Tor Browser, and a recommendation to “write down the information to notebook (exercise book) and reboot the computer”. These are the essentials that suffice to explain how the infected user can navigate to the ransomware’s Decryption Service page.
This crypto parasite uses RSA, a hard-to-crack asymmetric cipher, to prevent the victim from opening the .cryp1 files. The above-mentioned Decryption Service site advises on the way to buy UltraDecrypter for 1.2 Bitcoin, which is about $500. The page also accommodates a deadline display feature that shows a digital clock counting down the time left from 96 hours, or 4 days. The ransom will become twice as big after the timer is zeroed out, in which case the victim will be billed $1000 for data recovery.
The best countermeasure for these types of threats is, of course, prevention through good security habits. Do not open and download fishy email attachments, keep the OS and programs up to date, and use a reliable antimalware suite. If the infection happens to be already in, the steps covered below should provide a great deal of recovery assistance.
Automated removal of UltraCrypter virus
Owing to an up-to-date database of malware signatures and intelligent behavioral detection, the recommended software can quickly locate the infection, eradicate it and remediate all harmful changes. So go ahead and do the following:
1. Download and install the antimalware tool. Open the solution and have it check your PC for PUPs and other types of malicious software by clicking the Start Computer Scan button
2. Rest assured the scan report will list all items that may harm your operating system. Select the detected entries and click Fix Threats to get the troubleshooting completed.
Ways of non-ransom recovery of .cryp1 files
Cracking the crypto used by this ransom trojan is more of a science fiction thing rather than an attainable prospect for the masses. This is why the troubleshooting in predicaments of this sort is a matter of two approaches: one is to pay the ransom, which isn’t an option for many victims; and the other is to apply instruments that take advantage of the ransomware’s possible weaknesses. If the latter is your pick, the advice below is a must-try.
Backups can make your day
Not only are you a lucky person in case you’ve been backing up your most important files, but you’re also a wise and prudent user. This isn’t necessarily a resource-heavy activity these days – in fact, some providers of online services are allocating a sufficient size of cloud storage space for free so that every customer can easily upload their critical data without paying a penny. Having removed UltraCrypter ransomware, therefore, all you have to do is download your stuff from the remote server or transfer it all from an external piece of hardware if that’s the case.
Restore previous versions of encrypted files
A positive upshot of using this technique depends on whether or not the ransomware has erased the Volume Shadow Copies of the files on your PC. This is a Windows feature that automatically makes and keeps the backups of data elements on the hard drive as long as System Restore is enabled. The cryptoware in question is programmed to switch off the Volume Shadow Copy Service (VSS), but it has reportedly failed to in some cases. Checking one’s options regarding this workaround is doable in two ways: through the Properties menu of each file or by means of the remarkable open-source tool called Shadow Explorer. We recommend the software-based way because it’s automated, hence faster and easier. Just install the app and use its intuitive controls to get previous versions of the encrypted objects reinstated.
Data recovery toolkit to the rescue
Some strains of ransomware are known to delete the original files after the encryption routine has been completed. As hostile as this activity appears, it can play into your hands. There are applications designed to revive the information that was obliterated because of malfunctioning hardware or due to accidental removal. The tool called Data Recovery Pro by ParetoLogic features this type of capability therefore it can be applied in ransom attack scenarios to at least get the most important files back. So download and install the program, run a scan and let it do its job.
Revise your security status
Post-factum assessment of the accuracy component in malware removal scenarios is a great habit that prevents the comeback of harmful code or replication of its unattended fractions. Make sure you are good to go by running an additional safety checkup.
