What is WannaCry 3.0 ransomware virus?

The third installment of WannaCry finally emerges

WannaCry 3.0 functions as a third version of the notorious WannaCry[1] malware. Almost a month has passed since the world was struck by the malware on May 12th, 2017. It wrecked havoc globally: users who have been using outdated Windows versions have experienced the full assault of this menace. Specifically, the malware exploited the EternalBlue vulnerability in SMB servers. With the assistance of the hacking tool, leaked by Shadow Brokers, who stole the original tool from the National Security Agency, the developers had devised a cyber menace. The malware penetrated into the systems of hospitals, train stations, and other smart devices. Luckily, the malware did not retain the world as a hostage for long – an IT expert[2] purchased an unregistered domain and activated a “kill switch.” Soon after the campaign was launched, its alternative versions have appeared: WNCRY, Wanna Crypt0r 2.0, Wanna Decrypt0r 2.0, etc.[3] Recently, the third version was detected online. In this article, you will discover the options to remove WannaCry 3.0. The picture showing the emrgence of WannaCry 3.0

After the original version has been finally terminated, IT experts joined forced to analyze the threat and come up with countermeasures. Further analysis revealed that some extracts of the source code contained similarities to the viruses created by Lazarus group of hackers suspected to share the support of the North Korea government. While the media quickly picked up the habit to put all the blame on the said government, other IT experts noted that the ransom note seemed to be translated rather than written by a native speaker. They voiced their opinions that the real culprit might have originated from China.[4] While cyber security forces indulged in such speculations, the hackers worked on the third version. The latest edition – WannaCry 3.0 malware. This time the developers made sure to fix any possible flaws. Certainly, they have deleted the main weakness of WannaCry – “kill switch.” It was developed for self-defence purposes. If executed on a virtual machine, in order not to reveal its true origin, the malware would activate a kill switch. However, it also happened to be a weakness which allowed the IT specialist to terminate the attack. Subsequent versions were said to have alternative “kill switch” buttons. However, WannaCry 3.0 ransomware is not supposed to possess this peculiarity. On the other hand, there are higher detection chances. IT specialist Matthieu Suiche confirmed that the latest version of the threat had entered the cyber space. He spotted that the third installment connects to domain. Such valuable discovery would undoubtfully contribute to the prevention of the ransomware. Lastly, cyber security specialists question whether the same felons launched the third version. Wannacry 3.0 and WannaCry ransom notesWannaCry 3.0 technical capabilities are still wrapped in the veil of mystery.

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
