Ransomcuck Virus – How Does It Infect

To conduct an attack, Ransomcuck’ malicious payload needs to be dropped on the targeted computer. This can happen in two main ways – via a malicious file that is disguised to trick users into opening it or via a malicious URL that may cause automatic download and execution on the victim PC.

Was auch immer der Fall sein kann, the virus may be spread via spam e-mail messages that may contain boththe URLs or malicious attachments. Once it has been sent out massively to a pre-programmed list of e-mail addresses the messages containing the malicious files may vary. Beispielsweise, one spam message may claim that the user has paid for an order and provide an “Invoice” which could be the malicious file. But there may also be messages, saying the user has been added as a friend on Facebook with a fake “See More” button that instead of leading to Facebook, may transfer the user to a malicious web link that can cause the infection

Ransomcuck Ransomware In Detail

Once Ransomcuck has been executed on your computer, it may directly drop and execute it’s files without any permission and without you noticing. The malicious files may be more than just one .exe file, and they may be located in the following key Windows folders:

  • %AppData%
  • %Wandernd%
  • %Temp%
  • %Local%
  • %Systemdrive%
  • %System32%

The malicious files of Ransomcuck may contain different names, beispielsweise:

Once the Ransomcuck virus is on your computer, it may also attack the Run and RunOnce registry keys, creating value strings with the location of the file encryptor and the ransom notes, so that they are executed every time you start Windows.

After the primary encryption module of the Ransomcuck malware infection has been executed, the virus may look for a variety of file types to encrypt. It looks primarily for files that are important and often used, sowie:

  • Unterlagen.
  • Datenbanken.
  • Audiodateien.
  • Video-Dateien.
  • Dateien, die mit häufig verwendeten Programmen, wie Photoshop, beispielsweise.
  • Präsentationen.
  • Bilder.

The Ransomcuck virus is very clever in its actions, skipping important Windows folders to encrypt files in them because this may damage your operating system.

To encrypt the files of it’s victims, the Ransomcuck virus uses the .cuck or .ransomcuck file extensions after the files. Files encrypted by this ransomware, look like the following and cannot be opened by any software:

This is because the Ransomcuck virus uses two of the strongest encryption algorithms out there to scramble the structure code of the files – AES (Advanced Encryption Standard) and RSA (Rivest-Shamir-Adleman) Chiffren. The AES cipher is being used for one and only purpose to encrypt the files themselves, generating a unique decryption key. This decryption key is then saved and encrypted with the RSA algorithm, and then this information is sent either via TCP or UDP traffic to the servers of the cyber-criminals, making them the only ones in power to unencrypt the files.
