They’ll take more manual steps to encrypt servers, exfiltrate data – or do both. And then, instead of encrypting one or two or ten machines, they’ll encrypt everything.” Next, they encrypted servers in the most painful way possible, thus motivating companies to pay tens of thousands of dollars for a decryption key.
And studies have revealed that the newly developed file-encrypting malware is using an Open-source password management library for encryption and is having capabilities of remaining anonymous, ex-filtrate data, and having abilities to give control to remote servers. The third is something astonishing to read!

How WannaCry works This ransomware tries to access a hard-coded URL, and, in case it can’t, it starts to encrypt files in different formats. Once the files are encrypted, the user sees a ransom notification that demands $300 in Bitcoin. This virus can encrypt files on fixed drives, removable drives, network, and RAM disk drives.
It targeted Microsoft Windows operating system by encrypting the data on the victim’s machine and seeking ransom in exchange for a promise to decrypt all the encrypted files and potentially undo the damage, but that’s far from the truth, as we discuss further! We need to unzip the archive to access the executable.
