The method allows hackers to send the virus to large lists of potential victims. The attachments to malicious email spam messages usually have Word documents or other types of files which users open without hesitation.

Another infection tactic related to emails is hyperlink inserted in the content of the messages. The links are usually labeled as leading to a familiar website or a file of user interest.

Computer criminals behind this new ransomware can be using malicious sites or download portals to distribute malware of different kinds, including .puma Ransomware Virus virus. A popular option is the use of infected documents which may be of different types ‒ spreadsheets, rich text documents, presentations and databases. They are modified to initiate the virus once the built-in scripts are run. Usually when the files are opened a notification will ask the users to run the macros (scripts).

Impact of .puma Ransomware Virus Ransomware Virus

The crypto virus associated with the extension .puma has been identified as a strain of STOP ransomware. In case that your system has been infected by this threat, it restricts your access to valuable files and forces you to pay a ransom.

In order to reach the encryption stage of its infection, .puma ransomware establishes several malicious files on your machine. One way to achieve this is by creating these files directly on the system. Another approach is by dropping them after accessing its command and control server. Unfortunately, when the code of the ransomware is designed to access your network it could easily spread its infection payload across all connected devices. That’s why it is recommendable to consider its complete removal from the infected device as soon as possible. The guide at the end of this article will help you to isolate the infection from the network and prevent further compromises.

Soon after .puma ransomware establishes all malicious files needed for the attack, it starts to execute them in a predefined order. Their execution interferes with essential system settings which in turn enable the ransomware to utilize its built-in cipher module and encrypt target files. Among the affected system components is likely to be the Registry Editor. It’s a hierarchical database that stores information on how and when certain files and processes should be loaded in order that the system could operate smoothly. Eventually some of the keys there have functionalities that perfectly match ransomware’s goals.

These keys are Run and RunOnce. Since the key Run manages the automatic execution of all essential system files, objects and processes on each system start, it is often plagued by ransomware infections. When the ransomware adds its malicious values under this key, it becomes able to infect the system each time you turn it on. So when you reach the removal process make sure to check all registries for any present malicious values.

After system changes, .puma virus loads its built-in encryption module to corrupt predefined types of files. The list of corrupted data could include all of the following:

  • Backups
  • Databases
  • Archives
  • Videos
  • Music
  • Images

When a file is encrypted by this ransomware it appears such as it is broken. In addition, its name contains the specific extension .puma.

All of the above mentioned unpleasant consequences enable .puma ransomware to extort a ransom payment from its victims. How the extortion happens is via a ransom note. This note is contained in a file named !readme.txt. It appears on screen at the end of the attack. Here is what it reads:
