CryptoWall 5.1 does not cease terrifying the virtual community

CryptoWall 5.1 virus (also called as CryotoLocker) has emerged to accomplish its menacing mission – to encrypt users’ data. This particular group of ransomware emerged in 2014 and throughout these couple of years evolved into a massive ransomware campaign. Its name resonated in the most remote places of the world as corporations or ordinary people having at least reasonable Internet connection risked getting infected with this malware. In the beginning, it started out as ad-based malware [1]. However, soon it shifted from this method to a more exquisite one. Like the original version, the fifth installment employs an AES-256 algorithm to lock out personal users’ data. Comparing it with AES-128, it generates much longer and, thus, less crackable key. Such boost in computer viruses has led companies to reconsider their data security systems [2]. The latest version of this cyber menace should not be underestimated. If it happened to corrupt your files, proceed to CryptoWall 5.1 removal guide. Reimage is a tool which ensures complete elimination of the virus.

Ransomware has remained a hot topic in the past months since every day a new file-encrypting malware emerges. What is more, samples continuously assault medical institution and may even point their attention to medical IoT devices as they are upgraded to the “smart mode” [3]. There are several explanations to such activity. First of all, public exposure of open-source ransomware designed for educational purposes helps hacker-wannabees to learn the basics of this cyber menace. Likewise, within a short period of time, they generate their own virus and unleash it online. What is more, they quickly learn the usage peculiarities of AES and RSA encryption codes. The former usually encrypts the data while the latter encodes the very encryption key. Consequently, such action eliminates all chances of easy data recovery. In relation to this, CryptoWall 5.1 malware, which is alternatively known as Il tuo computer e stato infettato da Cryptolocker! ransomware, also uses the same method to lock out files [4]. Here is a short extract from the ransom note:

All files having the .locked extension have been blocked; you need to unlock the private key.

While the public key и been saved in a directory of your computer system, the private и been sent to our server, to get it you have to pay the amount of 250 €.
As soon as the amount is credited with one of the payment methods, you will receive by mail the private key, and regain access to your data.
Otherwise, at the end of 48h provided for the payment of the ransom, the private key will be deleted, and it will no longer be possible to recover files.
CAUTION: Removing cryptolocker will not restore access to encrypted files.

Even though the original ransom note is displayed in the Italian language, users of other regions should stay alerted. CryptoWall 5.1 ransomware urges its victims to transfer the money within 48 hours. It is a common technique to scare users. Taking into account how much profit all versions of this malware managed to collect [5], do not foster hopes of getting the files back. Instead, remove CryptoWall 5.1 right away.
