Killnet is a recently discovered ransomware infection. It has been causing severe damage and forcing victims to pay ransom money by encrypting their files. It is programmed to encrypt files (rendering them useless) until a certain ransom amount is paid.
This threat can be easily identified by the “.Killnet” extension that it uses to rename files. For example, a file named “photo.jpg” would appear as “photo.jpg.Killnet”, “work.doc” as “work.doc.Killnet”, and so on. It also generates ransom note “Ru.txt” (in Russian language) on infected PC upon successful encryption of all the data.
Unfortunately, Killnet virus infected files are not decryptable by any free software. Attackers force users to pay huge sums of money as ransom fees to buy decryption tools. Read this guide to know how to delete this virus and recover your files.
What is Killnet Ransomware?
Killnet is a powerful crypto locker virus. It uses an advanced encryption algorithm to lock files. It is designed to sneak on the targeted computer and encrypt the user’s data. Then it renames all the files by adding its own extension. Then this nasty virus generates a ransom note after rendering all the files inaccessible. Killnet Ransomware aims to extort money from victims as payment for the decryption tools and private keys.
This nasty .Killnet File Virus can encrypt all types of files (images, videos, music, documents, backups, etc.) on the infected machine. You will not be able to access any of the data without decrypting them. This virus can also affect files on connected USB drives and external hard drives. Ransom note instructs victims to contact attackers and pay the ransom fees through cryptocurrency. However, we strictly advise you not to co-operate with the cybercriminals behind this ransomware virus.
How Does Killnet Virus Attack Users?
Attackers behind Killnet virus use several mass targeting methods. The spam email campaign is one of the most used techniques to spread threats online. Cybercriminals send fake emails containing legit services and company’s names. These emails carry malicious attachments and links to suspicious sites.

Killnet virus could also get distributed via Bundled freeware programs, social media, and peer-to-peer file-sharing services. Downloading pirated software or fake software and illegal patches can bring this threat to your PC. Clicking on misleading pop-up ads, alerts, banners, offers, etc. can redirect the browser to suspicious sites. Those websites could trigger the automatic download and installation of malware secretly. Check important tips at the end of this article to prevent such malware attacks in the future.
