WannaCrypt virus updated: developers removed ransomware kill-switch
WannaCrypt virus is a malicious computer program that is set to corrupt files on Windows OS except Windows 10[1]. It usually adds .wcry, .wncry, or .wncrypt file extensions to files that it distorts. Although the ransomware hit the headlines after May 12, 2017, when it was used in a massive cyber attack that affected over 230,000 computers[2] worldwide, versions of it were spotted back in February. The virus has quite a lot of different names, including Wcrypt, WannaCryptor, Wana Decrypt0r 2.0 and even more, however, the name that draws everyone’s attention the most is WannaCry and the second version of it. The malicious program is extremely dangerous, and PC users should take whatever it takes to protect their computers because as soon as this virus enters the system, it encrypts files using an AES-128 cipher, meaning it is no longer possible to open or edit them. Although such attack can bring painful consequences, companies affected by it can lose years of work and experience financial losses, because the virus tends to replicate itself on connected computers and damage data stored on them as well[3].
Unfortunately, virus successfully attacked some giant companies such as Telefonica[4], England’s National Health Service, and dozens of other companies. The ransomware typically asks to pay $300 per computer if the ransom is paid within three days or $600 later on. The virus promises to delete all data on the computer if the PC user refuses to pay up or fails to collect the required amount of money in 7 days. However, we do not suggest paying the ransom because the criminals might not help you to restore your data. Besides, if you pay, you would fund further ransomware projects, meaning that you can be infected again. Cyber criminals have already earned a whopping $50k[5], and such sum can be used for evil purposes again. Therefore, if your files were corrupted, we suggest you start thinking about WannaCrypt removal. We usually recommend using anti-malware programs like Reimage or SpyHunter 5Combo Cleaner to delete the malware with ease.
WannaCrypt ransomware infects Windows computers, corrupts files stored on them and then demands $300. We advise victims NOT to pay the ransom because criminals might not help you to restore encrypted data!
Essential facts to know about ransomware distribution
WannaCrypt ransomware differs from typical malware variants because it uses a more sophisticated trick to attack Windows computer systems. The cyber attack launched on May 12, 2017, managed to hit over 150 countries. Experts suggest an explanation why the ransomware has proliferated so rapidly – although the majority of malware samples reached victims with the help of phishing emails, the primary infection vector was EternalBlue exploit combined with DoublePulsar backdoor, which was developed by U.S. NSA. These tools helped the ransomware spread through connected computers and corrupt data stored on them. No matter if you have been infected with this ransomware or not, we highly suggest reading these tips on how to survive the WannaCrypt0r attack. If you are using a computer running Windows 10, most likely you won’t fall victim to this ransomware. However, older versions of the indicated operating system proved to be vulnerable to the ransomware.
