What is the Onion Ransomware or Virus and How to Remove it?

Onion virus is associated with the group of file-encrypting viruses. It encodes files and introduces 72-hour elapsing time clock. According to Kaspersky Lab, this ransomware is called Onion because it uses the Onion Router (TOR anonymous network) to hide its malicious nature and to make it difficult to track the creators behind this malware campaign. The ".onion" is a file extension that belongs to the virus and is an indicator of a compromise which is also associated with the Dharma and CryptoLocker ransomware campaigns. This family of crypto viruses has a solid foundation. Irrespective of the edition, these horrendous viruses have constantly been applying a hearty cryptographic mechanism that obstructs decryption. At the end of the day, your images, files, videos, databases, documents, and other important data are all locked.

How Onion Ransomware works

Just like other viruses, the Onion Ransomware infections are programs and they require some type of authorization to get access to your system. The Onion sneaks into your system with command and control servers located inside the anonymous TOR network. It tricks you into approving it by using many different strategies like spear phishing in online spam messages, fake skype messages, fake software updates, etc.

Cyber criminals can send you a malicious attachment or link and if you are not cautious, you welcome the infection onto your PC. This is the reason you have to be careful and vigilant. Without you being careless, hoodlums won’t succeed; they prey on your carelessness.

    Received via email:

    "There's a nasty virus also known as,"Wana Decrpt0r 2.0," it locks your files with the encryption .WNCRY at the end of every file. It will stealthily infiltrate your device and say,"Ooops, your files have been encrpted!" This is definitely a new type of virus because I haven't been able to get any information about it other than it being stealthy."
