After the rebranding of CryptXXX ransomware into UltraCrypter, the extensions it adds to files have been changing every few days, the latest one being .crypt1 or .cryptz.
Some crypto viruses are created and distributed by people obviously lacking tech skills, but the .crypt1 extension ransomware definitely doesn’t fall under that category. This is an edition of the CryptXXX hoax that superseded TeslaCrypt in the top part of the cyber extortion ‘food chain’. The newest iteration dubbed UltraCrypter features improved user interaction modules, enhanced anti-cracking mechanisms, and one more functionality that’s unique to these types of computer threats. It now contains a component called StillerX, which obtains the victim’s account credentials, including those for online gambling sites, virtual private networking tools, and possibly e-banking dashboards. Consequently, the criminals won’t get too upset if an infected user refuses to pay the file decryption ransom – they can take advantage of the compromise in other ways, too.
It doesn’t take much careless online activity on the average user’s end to become infected with the .crypt1 file virus. The black hats are in cahoots with the operators of the Angler exploit kit, also known as XXX, therefore their loader may be deposited onto PCs in a highly furtive fashion. The attack succeeds if the user visits a site with the Angler code in it, and as long as there are vulnerabilities in outdated software on the computer. Social engineering attacks over attachments in misleading emails are in the perpetrators toolset as well, moreover, these are easier to thwart.
This Trojan thoroughly scans the host machine for a bevy of files to encrypt. In particular, it focuses on locating valuable things, such as personal photos and videos, spreadsheets, text files, databases and the like. The RSA4096 cryptosystem, which the ransomware then uses to mutilate these items, is effectively an unbreakable asymmetric cipher. Meanwhile, it’s easy to tell which objects have been affected in the course of the attack, because they all have the .crypt1 or .cryptz suffixes concatenated to the initial filenames.
CryptXXX demands 500 USD for the unique private key, which will allow the decryption tool to restore all files. The ransom increases to 1000 USD if the victim lingers with the payment for more than 4 days. According to the latest reports, those who paid up are currently unable to download the decryption tool, even though the payment status is ‘completed’. As a response to this, the scammers have added a new Helpdesk tab on the ‘Decryption service’ Tor page, where frustrated victims can describe and submit their problem. However, relying on the criminals’ tech support is a lame approach. Instead, try several methods to recover the data for free without resorting to the assistance of people who caused the issue in the first place.
Automated removal of .crypt1/.cryptz 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 .crypt1/.cryptz 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.
