What is Pump Ransomware

After Pump Ransomware attacks your system, all data become chained by strong algorithms restricting access to it. The malware appends .pump extension to the files it encodes. For example, a file like 1.mp4 will acquire a new look of 1.mp4.pump and reset its original icon. The extension applied in the end means that your files are under encryption. Such modifications are usually accompanied by the creation of ransom instructions. In our case, the virus drops a text file called README.txt that will help you recover the files.

The content presented inside is short, cybercriminals only attached their e-mail address to call victims into contacting them. Then, they will supposedly give further instructions on how to purchase the decryption software. No matter how far the price goes, complying with the requests of swindlers is risky - they may become foolish in their promises and leave you no tools even after making a payment. Unfortunately, third-party software is not 100% capable of recovering the compromised data, but you should give it a try after removing Pump Ransomware from your computer in our tutorial below. Also, if you have an external copy of encrypted files, it will be helpful in recovering data completely.

How Pump Ransomware infected your computer

Ransomware infections are famously-spread via e-mail spam messages. Cybercriminals send them to millions of people with malicious attachments included inside. The goal is to tempt users into opening/downloading them by marking the letters with labels of high priory and importance. Sometimes the spam messages may be disguised as fake representatives of delivery firms that instruct you to click on links leading to download pages. Beware such content and never interact with it, unless you are sure it is legitimate and safe. Besides that, there are other distribution vectors we have not mentioned just yet - trojans, unprotected RDP configuration, backdoors, keyloggers, fake software cracking tools, and updates. Remember that all of the methods target users with inexperience and uncarefulness during the browsing activity. This is why you should keep track of what you are visiting on the web to not get caught by malware like Puma.
