CryptoKill Ransomware – In-Depth Analysis

CryptoKill is a virus that is of the file encryption kind. Once infected a given system, it makes the files on it no longer able to be opened. It is distributed all over the world, information on infection rate not available.

CryptoKill Ransomware – Infection Process

To cause an infection, CryptoKill ransomware uses different combination of tools. In addition to those tools, this ransomware virus may also use deceptive e-mails or other type of messages which could be used for a very specific purpose – to trick an unsuspecting victim that does not have much experience into opening a malicious web link sent on the mail or an e-mail attachment.

These objects are usually malicious and cause the infection by having a combination of different scripts and tools embedded in them, such as distribution malware (downloader), exploit kits and other type of malware and obfuscators that hide the infection activity from any protection software.

The cyber-criminals also have a pre-chosen list of potential victim e-mails to which the spammed e-mails are sent via spamming software. The spamming software also has a pre-set list of disposable e-mails it uses to avoid being flagged by performing simultaneous spam.

Once the misguided user clicks on an attachment or a URL, by believing the deceitful message on the e-mail, he or she immediately becomes infected and the CryptoKill virus drops the following files on the computer:

  • CryptoKill.exe
  • CRYPTOKILL_README.txt

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
