Another ransom threat one is to be aware of is the .crypz encryption virus. The plague owes its name to its adding the same-name extension to the files on a computer system. That is a distinct trait, but not the kernel. The greatest damage is, of course, the sophisticated modification that renders your data unreadable.
The variant under review was spotted by malware experts at the beginning of June. So far, there is no ultimate solution to undo the malicious data modification from scratch. Some roundabouts available are likely to enable the data recovery to a satisfactory extent. If that is the case, you are invited to consult the guiding part of this review skipping a couple of paragraphs below.
The .crypz invasion suggests a major problem with overall system security. The ransomware arrives exploiting vulnerabilities in the software installed so that it is good to have the applications updated in a good time.
The ransom amount claimed by the virus is quite high. Moreover, it may be still raised, if a victim refuses to pay until the deadline. As a rule, the amount exceeds USD 500. The payment method required is a Bitcoin transaction. The latter is a crypto currency, and the .crypz is basically a crypto virus.
The discussion is still ongoing whether Bitcoin further contributes to the success of the crooks. It is obvious, though, that the role of cryptocurrency tends to be highly exaggerated when it comes to the crypto-based extortion.
The malware applies a reasonable selection when encrypting the files on your computer system. At least, it spares some essential system files, but only to be able to claim the ransom within the affected computer system. On the other hand, the ransomware propagates over the local network whenever and wherever possible. Thereby the backups to network drives are not deemed to be a proper prevention method.
To notify its victims that they are expected to pay the ransom, the infection creates a reminder. It may overlap the current desktop wallpaper and is dropped for sure into each folder with the files encrypted. The message says the victim is to install a TOR browser and use it to execute the payment.
Any payments to the crooks do not ensure the data decryption. They ensure, however, that the hackers have further incentives to develop their scam schemes. The ransomware victims are advised to get rid of the .crypz virus and apply the recovery steps as outlined below.
Automatic removal of .crypz ransomware
The benefits of using the automatic security suite to get rid of this infection are obvious: it scans the entire system and detects all potential fragments of the virus, so you are a few mouse clicks away from a complete fix.
- Download and install recommended malware security suite
- Select Start Computer Scan feature and wait until the utility comes up with the scan report. Proceed by clicking on the Fix Threats button, which will trigger a thorough removal process to address all the malware issues compromising your computer and your privacy.
Unlock .crypz files
.crypz represents a unique category of malicious software whose attack surface reaches beyond the operating system and its components, which is why removing the virus itself is a part of the fix only. As it has been mentioned, it encrypts one’s personal information, so the next phase of the overall remediation presupposes reinstating the files that will otherwise remain inaccessible.
Launch data recovery software
Similarly to the rest of its fellow-infections, .crypz most likely follows an operational algorithm where it erases the original versions of the victim’s files and actually encrypts their copies. This peculiarity might make your day, because forensics-focused applications like Data Recovery Pro are capable of restoring the information that has been removed. As the virus further evolves, its modus operandi may be altered – in the meanwhile, go ahead and try this.
Take advantage of Volume Shadow Copy Service
This technique is based on using the native backup functionality that’s shipped with Windows operating system. Also referred to as Volume Snapshot Service (VSS), this feature makes regular backups of the user’s files and keeps their most recent versions as long as System Restore is on. .crypz virus hasn’t been found to affect these copies therefore the restoration vector in question is strongly recommended. The two sub-sections below highlight the automatic and manual workflow.
- a) Use Shadow Explorer
Shadow Explorer is an applet that provides an easy way of retrieving previous versions of files and folders. Its pro’s include an intuitive interface where the computer’s entire file hierarchy is displayed within one window. Just pick the hard disk volume, select the object or directory to be restored, right-click on it and choose Export. Follow the app’s prompts to get the job done.
- b) Use file properties
Essentially, what the above-mentioned Shadow Explorer tool does is it automates the process that can otherwise be performed manually via the Properties dialog for individual files. This particular approach is more cumbrous but just as effective as its software-based counterpart, so you can proceed by right-clicking on a specific file, which has been encrypted by .crypz ransomware, and selecting Properties in the context menu. The tab named Previous Versions is the next thing to click – it displays available versions of the file by date of the snapshot creation. Pick the latest copy and complete the retrieval by following the prompts.
Data backups work wonders
Ransomware like .crypz isn’t nearly as almighty and destructive in case you run regular file backups to the cloud or external data media. The virus itself can be completely removed in a matter of minutes, and the distorted information can then be just as easily recovered from the backup. Luckily, this is a growing trend, so ransom Trojans are hopefully going to become less subversive in the near future.
Verify thoroughness of the removal
Having carried out the instructions above, add a finishing touch to the security procedure by running an additional computer scan to check for residual malware activity
