CryptoShadow enters the ransomware market

CryptoShadow virus is presented as a file-encrypting threat. While the first two weeks did not introduce many exceptional viruses, hackers still keep IT experts preoccupied. During the last weeks, Cerber virus kept continuously terrorizing the virtual community. Likewise, many users might have got used to the news about yet another version of this destructive cyber infection [1]. While the gang behind the infamous threats decided to take a short break, other felons do not let the security researchers fade into boredom. Unlike some unsuccessful attempts, such as MerryChristmas ransomware, created to frighten users, this malware should not be taken too lightly. It employs an intricate AES encryption technique to encrypt files. If this misfortune has befallen you, there is no need to give in into despair. Read the article to get acquainted how to remove CryptoShadow. For that purpose, we recommend installing Reimage. It will ensure that CryptoShadow removal will be performed efficiently.

The image of CryptoShadow virus

Regarding the operation and the veneer of this virus, it seems that it has been oriented at Spanish-speaking netizens. Such assumptions have been made from the ransom note of this malware. It presents LEER_INMEDIATAMENTE.txt. The title says “Read immediately.” During the encryption procedure, CryptoShadow malware encrypts a file with AES algorithm. It generates a complex, unique key. The most viable to reclaim the files again is to either obtain the private key or use backup copies [2]. Additionally, the ransomware appends two types of file extensions: .exit and .doomed. These threats vary not only in the external outlook, but operation method, and diverse payment options [3]. Elaborating on CryptoShadow ransomware, it has been detected that it is the version of an infamous HiddenTear virus [4]. It has inspired numerous hacker-wannabees to launch their own crypto-malware. Depending on the complexity and structure, the workaround may take a while. Some threats such as Marlboro virus only took one day to crack [5], but the current malware seems to be a different matter. Lastly, we would like to dissuade you paying the ransom. Ransomware business has been booming since victims have remitted the demanded payment. However, only an astonishing minority retrieved the data back. Concentrate only on the idea how to remove CryptoShadow permanently.

In order to escape them, arm up with effective security application. In this case, we offer the combination of an anti-virus and anti-spyware application.
