Das Aufkommen der Cloak Ransomware

The Emergence of the Cloak Ransomware

First detected around December 2020, Cloak is a ransomware variant that represents a significant level of risk due to its high level of encryption. The implications of a Cloak Ransomware infection are extreme, as it uses an impenetrable algorithm to lock victims‘ files, appending the ransomware file extension „.cloak“ to them. Two publicized incidents involving the Cloak Ransomware include an attack on an unnamed Japanese company, and another on a medical facility, leading to significant losses and extended downtime.

Information on „Cloak Ransomware“

Additional Information

• Cloak Ransomware targets a wide array of file types, ranging from documents, databases, and images to videos and music files.
• Unlike some other ransomware variants, Cloak does not have a known leak site where the actors post information about their victims.
• The Cloak Ransomware operates by first scanning the victim’s computer for certain file types, encrypting them, and then displaying a ransom note.
• Cloak ransomware does not typically attempt to steal data before encrypting the victim’s files. The primary goal of the threat actor appears to be monetization from ransoms paid.
• In some cases, Cloak Ransomware can be decrypted without paying the ransom using sophisticated decryption tools. However, it is always recommended to maintain a regular backup regimen to avoid the loss of important data in the event of a ransomware attack.

Cloak Ransomware represents a formidable threat due to its encryption strength and wide target scope. Organizations must remain proactive in their cybersecurity measures to mitigate potential damage and ensure minimal disruption in the event of an attack.
