WannaCryptor Ransomware (WanaCrypt0r Ransomware) Description
The first major ransomware attack of 2017 involves the use of the WanaCrypt0r Ransomware, an improved version of the '.wcry File Extension' Ransomware which, unfortunately, leverages one of the leaked NSA exploits to exploit vulnerable computers running Windows XP. It is unknown which is the hacking group behind the WanaCrypt0r Ransomware attacks, but one thing is for certain – whoever they are, they certainly know what they are doing. The targets of the WanaCrypt0r Ransomware don't appear to b chosen randomly since most of the infected machines appear to belong to major companies in various industries around the world. However, the biggest victim of the WanaCrypt0r Ransomware appears to be Britain's National Healthcare Service (NHS), as many of the hospitals on the island have had their data locked by this file-encryption Trojan. Apart from the British NHS, the organization behind the WanaCrypt0r Ransomware also has attacked a large number of computers in Taiwan, Russia, Spain and Ukraine.
The initial infection with the WanaCrypt0r Ransomware usually occurs via spam emails that contain an infected attachment. Once the WanaCrypt0r Ransomware is deployed to a computer, it attempts to use the aforementioned NSA exploit named 'EternalBlue' to spread itself to other computers on the same network. The 'EternalBlue' exploit looks for an unpatched vulnerability in the SMB (Server Message Block) service and attempts to use it to spread to other computers on the same network. This worm-like behavior is very threatening as it has allowed the WanaCrypt0r Ransomware to take the medical records and data of entire hospitals as a hostage. It is important to mention that the 'EternalBlue' exploit only affects unpatched and insecure versions of all OSes between Windows XP and Windows 2012. Unfortunately, many hospitals and government institutions worldwide use outdated software, which gives the authors of the WanaCrypt0r Ransomware an opportunity to increase the damage their attacks can cause drastically.
The WanaCrypt0r Ransomware uses a secure encryption, and it is highly unlikely that we'll see a free decryptor anytime soon. When the file-encryption Trojan infiltrates a computer, it will proceed to encrypt data found there by using a combination of AES and RSA keys. Every locked file also will have its extension changed to '.WCRY' or '.WNCRYT.' The threat targets a total of 166 file extensions so that, unfortunately, its attacks are almost guaranteed to leave most files on computers in an encrypted state.
After the encryption routine is completed, the WanaCrypt0r Ransomware will proceed to display the ransom message which is stored in several files:
- @Please_Read_Me@.txt – for a text version of the ransom note.
- @WanaDecryptor@.bmp – image which contains a ransom message and is automatically set as the default Windows background.
- WanaDecryptor.exe – decryption utility which only works if the payment is made, and also contains a ransom message.
- @WanaDecryptor@.exe – an alternative file whose purpose is to acquire the 'WanaDecryptor.exe' file if the victim's antivirus software has removed it.
The ransom note containing more details is found by launching 'WanaDecryptor.exe.' This will spawn a new program window that contains a timer, the message, and buttons used to check the payment status and decrypt the files if the payment has been verified. The authors note that victims have a limited amount of time to pay the ransom sum or they'll suffer different consequences – first, the ransom sum will be increased, and later their decryption key will be deleted. It seems like the WanaCrypt0r Ransomware's ransom sum is fixed to $300 and, naturally, the authors want the money to be transferred via Bitcoins. The ransom note features translations to several languages - Bulgarian, Chinese (Simplified), Chinese (Traditional), Croatian, Czech, Danish, Dutch, English, Filipino, Finnish, French, German, Greek, Indonesian, Italian, Japanese, Korean, Latvian, Norwegian, Polish, Portuguese, Romanian, Russian, Slovak, Spanish, Swedish, Turkish, Vietnamese.

The authors of the WanaCrypt0r Ransomware are probably aware how powerful their crypto-threat is, and that's why they've added several additional features to ensure that attacks will inflict the maximum amount of damage. When launched, the WanaCrypt0r Ransomware will execute several commands, which aim to terminate processes related to popular database servers. This way, the database files will not be locked, and the WanaCrypt0r Ransomware will be able to access and encrypt their contents. In addition to this, the WanaCrypt0r Ransomware will attempt to wipe the Shadow Volume Copies, but this might not always work successfully so that some victims might be able to recover from the attack partially via the Shadow Volume Copies.
Paying the ransom sum that the WanaCrypt0r Ransomware demands is not advised, because the money might be used to fund future projects of the hacking group, therefore making it more likely that you'll end up meeting another one of their sinister cyber threats. The best way to counter threats like the WanaCrypt0r Ransomware is to make sure that they never have a chance to get to your files. In the case of the WanaCrypt0r Ransomware, the best thing to do is to keep your anti-virus software active and updated, as well as to apply the latest security updates for your operating system.
