What is .cash file virus?

Also referred to as DHARMA ransomware1, it modifies your documents by means of encrypting them and demanding the ransom to be paid allegedly to restore access to them. [cryptocash@aol.com].cash indicates cryptocash@aol.com as a channel for contacting the ransomware authors.

The DHARMA ransomware is active again through its new cryptovirus bearing the name of .cash. This particular virus family modifies all popular file types by means of adding the .cash extension, thus making the data absolutely unavailable. The victims simply cannot open their important documents anymore. The ransomware also assigns its unique identification key, just like all previous representatives of the virus family. As soon the file is encrypted by the ransomware, it obtains a special new extension becoming the secondary one. The file virus also generates a ransom note providing the users want instructions allegedly to restore the data.

What Is It and How Did I Get It?

The .cash ransomware is most commonly spread by means of a payload dropper. It runs the malicious script that eventually installs the file virus. The threat circulates actively on the web, considering the facts about the ransomware mentioned in the VirusTotal database. The .cash ransomware may also promote its payload files through popular social networks and via file-sharing platforms. Alternatively, some free applications hosted on many popular resources may also be disguised as helpful tools, whereas they instead may lead to the malicious scripts that injected the ransomware.
