What is CryWiper Ransomware

CryWiper is a devastating virus that damages the configuration of data to make it inaccessible and then demands money from victims for fake decryption. CryWiper developers disguise their software as ransomware that encrypts data, however, it is in fact a data wiper that simply corrupts the files. While running “encryption”, the virus deletes all shadow copies from the root drive and appends the new .CRY extension to highlight the files. For instance, a file originally named 1.pdf will turn into 1.pdf.CRY and become permanently damaged. After this, CryWiper creates a file called README.txt with misleading decryption instructions. It is known that CryWiper avoids damaging .exe, .dll, .lnk, .msi, and .sys files and others stored in Boot, System, and Windows directories. In addition, this virus has also been observed getting distributed via the browserupdate.exe malicious file, programmed in C++ language, and targetting organizations that are localized in Russia.

README.txt
All your important files were encrypted on this computer.
You can verify this by click on see files an try open them.
Encrtyption was produced using unique KEY generated for this computer.
To decrypt files, you need to otbtain private key.
The single copy of the private key, with will allow you to decrypt the files, is locate on a secret server on the internet;
The server will destroy the key within 24 hours after encryption completed.
Payment have to be made in maxim 24 hours
To retrieve the private key, you need to pay 0.5 BITCOINS
Bitcoins have to be sent to this address: bc1qdr90p8l5jwen4ymewl7276z45rpzfhm70x0rfd
After you've sent the payment send us an email to : fast_decrypt_and_protect@tutanota.com with subject : ERROR-ID-- (0.5BITCOINS)
If you are not familiar with bitcoin you can buy it from here :
SITE : www.localbitcoin.com
After we confirm the payment , we send the private key so you can decrypt your system.

The note sheds light on what must be done to return the “encrypted” files. It says victims have to pay 0.5 BTC (≈ 8400 USD) within 24 hours, otherwise, the unique decryption key will be deleted from the servers of cybercriminals – de facto making decryption permanently impossible in the future. Once the payment is made, victims are guided to notify the extortionists via e-mail (fast_decrypt_and_protect@tutanota.com) and include the specified text (from the text note) in the subject of an e-mail message. However, please note that CryWiper does not encrypt, but rather damages all the targetted files. This means using any decryption methods (including the payment to cybercriminals) is completely pointless. Those trusting these cybercriminals will most likely be scammed in the end. Users can only recover their data from a backup or shadow copies if Windows did not store them in the system drive (“C:”) at the time of infection. If you do not have any copies of files on external devices or cloud storage, you can still give a try to some third-party recovery tools discussed in our article below. The success will depend on whether you have any shadow copies stored on other non-system drives, which is unfortunately rarely the case. Whatever the case, it is important to make sure CryWiper is deleted from your system – to prevent it from possibly damaging other types of data. Use our guide below to do so with a free dedicated antivirus.

How CryWiper Ransomware infected your computer

As was previously mentioned, CryWiper starts its malicious activity after users initiate the malicious file named “browserupdate.exe”. Numerous reports indicate that this file is likely distributed via a phishing website that claims users’ website is outdated and therefore baits into downloading the malicious file that will ostensibly update it. In fact, it will simply install CryWiper onto a system. This distribution method is not yet verified, however, it is likely that cybercriminals have used it indeed. Alternatively, malicious files that inject various malware can also be spread via e-mail spam letters, trojans, deceptive third-party downloads, fake software updates/installers, backdoors, keyloggers, botnets, and system exploits. Similar to deceptive websites, cybercriminals may send deceptive e-mail letters that trick others into opening some malicious attachment (.DOCX, .XLSX, .PDF, .EXE, .ZIP, .RAR, or .JS extensions). Please note that many such distribution vectors use click-bait tricks to make users believe they are downloading authentic and genuine software. Never trust suspicious/untrustworthy pages that force you to do to something. Always double-check the displayed information and download software solely from official and trusted resources.

CryWiper Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox
