What is Ryuk ransomware?

Ryuk ransomware is a crypto-type virus that encrypts computer system and can be spread by phishing emails, malicious pop-up messages, injected in any third-party files, and more. Once encrypted using the strongest military algorithms RSA4096 and AES-256 by the professional hackers, they demand ransom money, and instead of ransom money, they promise to provide a special digital key to decrypt the data.

So, once the demanding money paid to hackers, they provide the digital key or the way of access all of the hacked data. Hackers mostly choose targetted companies or organizations according to their turn over or value of the data. In that scenario, the organization or company easily accepts the ransom as they don’t want to lose their data and hard work.

• First, hackers send phishing emails or pop-up messages to targetted computers. It also includes infected attachments, text files, Botnet, or Tricknet which gets downloaded.
• Then the virus transfers inside the system data via a connected or sharing network. So, dangerous!
• Finally, the Ryuk can be easily executed into the system in .ryk file extension and professional hackers can easily hack all the data access & encrypt within a couple of minutes or so.
• Once done, the victim will get a ransom note in a text file (.txt format). So, strange!

Hackers also warn victims that the encrypted files can’t be unlocked without their (hackers) special decoder. Photorec, RannohDecryptor, etc repair tools won’t come in handy and these tools can easily damage the files irreversibly. Hackers will demand ransom in Bitcoins as this is illegal.
