What is WannaCry Ransomware

WannaCry (also referred to as Wcry, Wana Decrypt0r 2.0, WanaDecryptor, and WNCRY virus) is a ransomware infection that encrypts personal files using AES-128 algorithms and demands victims to pay for decryption. The virus was discovered by a security researcher S!Ri and there are a couple of known WannaCry variants. Depending on which variant attacked the system, files affected by encryption will be altered using the .wcry, .wncry, or WNCRYT (for encrypted .bmp files). For instance, a file like 1.pdf will change to 1.pdf.wcry or similarly depending on the ransomware version. Following this, the virus displays decryption instructions in a force-opened pop-up window. One of the variants changes the desktop wallpapers as well. The Wana Decrypt0r 2.0 variant also creates a separate ransom-demanding note called @Please_Read_Me@.txt.

Despite the text of instructions and its visual appearance vary in different WannaCry variants, their essence is more-less the same. Overall, cybercriminals claim they are the only figures able to recover access to data. In order to do so, victims are demanded to pay a certain fee in Bitcoin cryptocurrency to extortionists. Unless victims send the payment within the displayed countdown (usually 3 days), the price for decryption will double and it will cost twice more of the original price. If victims fail to pay within 7 days, the decryption key will be erased and victims will no longer be able to recover their files with the help of the swindlers. Additionally, some WannaCry variants offer to test decryption by sending some encrypted files and getting them unlocked for free. All of these techniques are meant to intimidate/accommodate victims and therefore make them agree to pay the ransom.

As a rule, decryption without the help of cybercriminals is almost impossible when it comes to the majority of ransomware infections. The only free recovery method for victims is usually to use their own backup copies if such are available. However, the good news is that there is actually a third-party decryptor that can be downloaded and used for free decryption – independent of the threat actors. The tool was released in 2017 (the time when WannaCry Ransomware was active the most) on GitHub by Adrien Guinet (tested to work on Windows XP, 7 x86, 2003, Vista and Windows Server 2008). Instructions on how to use it are available on the website, however, you can also check out this video for a better understanding.

Please note that this tool does not have a 100% success rate of decryption. There are cases when it fails. However, if you can neither afford to pay the attackers nor there are any available backups to use, then it is definitely worth giving a try to this tool. After decrypting your files, remember to delete WannaCry Ransomware from your system. Note that WannaCry is also known to sometimes deliver additional malware into the system (such as DOUBLEPULSAR malware). Thus, it is important to not only delete the ransomware but also thoroughly scan it for additional malware. You can follow our guide below to do so. In addition, we also attached information about other general decryption/recovery methods that can sometimes be effective as well.

How WannaCry Ransomware infected your computer

Initially, WannaCry Ransomware succeeded in mass distribution thanks to an NSA vulnerability called EternalBlue in 2017. Cybercriminals exploited this vulnerability in the SMBv1 protocol to get a foothold on vulnerable machines connected online. Although this vulnerability no longer exists, this and other ransomware infecti can still be distributed using other methods as well. Such may include e-mail spam letters, trojans, deceptive third-party downloads, fake software updates/installers, backdoors, keyloggers, botnets, other system exploits, and so forth. Many inexperienced users are fooled into interacting with some malicious content. For instance, ransomware or trojan developers quite often send e-mail letters that are disguised as legitimate companies/entities (e.g., delivery companies, tax authorities, banks, and so forth).

As a rule, such letters use phishing techniques to make users open some phishing link or malicious attachment (.DOCX, .XLSX, .PDF, .EXE, .ZIP, .RAR, or .JS extensions). Once such attachments are opened, the hidden infection will most likely end up installed on the targeted system unless there is special anti-malware software in place. Do not trust such letters and delete them immediately if there is anything that looks suspicious in them. You should also download software only from trustworthy and legitimate websites. Avoid downloading torrents and other files that endorse installers of pirated, cracked, or other illegally distributed software. Read our article below to learn more practical information about how to protect yourself against such and similar threats in the future.

2. Back up your files

idrive backup

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. WannaCry 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
