removal by Julie Splinters - - | Type: Ransomware

Besides Windows KillDisk targets Linux OS

The original version of Killdisk virus rampaged on the virtual space as a virus capable of eliminating and altering crucial files. However, the success of several ransomware families, such as CrytpoLocker and Locky, encouraged crooks who specialized in a different type of malware to take up a new sport – modify their malware into file-encrypting threats. Likewise, the developers of notorious KillDisk decided to enter into the market as well [1]. What is more, the crooks decided to play big and demand 222 bitcoins in exchange for the files! Users may dread after finding such cyber-mutant on their operating system. Nonetheless, virus researchers work restlessly to combat the cyber threats. If this menace targeted your computer as well, initiate Killdisk removal. Reimage speeds up the procedure.

The current threat gained its title for its specifications. This malware has been on the market quite for a while. Due to its destructive features paralyzing a system, the felons aimed it at industries and big corporations. KillDisk malware is capable of wreaking an operating system and making a device completely unbootable. It has been combined with other trojans, such as BlackEnergy virtual infection, to deliver a destructive attack on an energy supply company. Such assault ended in the cease of electricity for about 1,4 million of Ukrainian population on December 23rd in 2015 [2]. It seems that such effects did not satisfy the racketeers.

KillDisk now contains ransomware specifications

Now they decided to weave ransomware elements in their virtual infections. Such intentions materialized into Killdisk ransomware. Therefore, the current threat is not only capable of wiping the data on your local drives and but encode them. It also demands an astonishing 222 Bitcoin which is equal to $227 629 100 at the moment [3]. Likewise, the main target is suspected to be companies. However, there is no need to be tech-savvy to anticipate that the cyber criminals soon point their daggers to ordinary netizens. The current threat employs an RSA-1028 algorithm to encode files. In addition, the modified version of the malware encodes local hard-drives and network-mapped folders. Killdisk Wiper malware uses to cover their tracks, but specialists of CyberX suspect that the hackers known as TeleBots might be behind the attacks [4]. The gang has become quite interested in ransomware assaults as it significantly increases the number of their attacks in this specific field [5].

January 2017 update: the malware shifts its attention to Linux 

It seems that turning Killdisk wiper malware into ransomware was only just the beginning. Encrypting Windows users’ data and demanding 222 BTC is not enough. The cyber criminals decided to multiply their profits by developing a version suitable for Linux systems. In comparison with the version devised for Windows OS, its encryption methods differ from the former version. Specifically, the ransomware employs Triple-DES algorithm which runs 4096-byte cipher blocks to generate a unique decryption key. In addition, it targets a wide range, specifically, 17 subfolders to encode files. Killdisk malware, designed for Linux, appends “DoN0t0uch7h!$CrYpteDfilE” extension. However, the improvements do not only encompass modifications regarding encryption methods. The cyber infection modifies boot settings. It results in the ransom message being displayed as a start-up window. It contains the exact information as provided in the malware designed for Windows. Victims are supposed to purchase 122 bitcoins and then transfer them to the indicated address. In addition, the hackers provide an email address – – should the targetted users find any obstacles. In short, do not follow the hackers’ scenario but, instead, opt for the alternative solutions.
