Ransomware is now a common practice for money-motivated cyber criminals. It's basically a type of software written in any system-based programming language that has the ability to hijack victim’s computer, encrypts files and then ask for a ransom amount to get them back.</div>

One such ransomware dubbed Linux.Encoder targets Linux-powered websites and servers by encrypting MySQL, Apache, and home/root folders associated with the target site and asks for 1 Bitcoin (<b style="border: 0px; font-family: inherit; font-size: inherit; font-stretch: inherit; font-style: inherit; font-variant: inherit; line-height: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;"><i style="border: 0px; font-family: inherit; font-size: inherit; font-stretch: inherit; font-variant: inherit; font-weight: inherit; line-height: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;">$453.99</i></b>) to decrypt those crucial files.</div>

The Malware author released the third version of the Linux.Encoder ransomware, which security researchers from Bitdefender have managed to crack, yet again, after breaking previous two versions.</div>

However, before the team managed to release the Linux.Encoder decryption tool, the third iteration of Linux.Encoder ransomware, which was first discovered by antivirus maker Dr.Web, has infected a nearly 600 servers worldwide.</div>

Ransom32 allows its operators to deploy the malware very quickly and easily. It has a dashboard that enables operators to designate their Bitcoin addresses to which the ransom can be sent. The dashboard also shows stats about how much Bitcoins they have made.</div>

The copy of Ransom32 was first analysed by Emsisoft, which found that the new ransomware family, which embedded in a self-extracting WinRAR archive, is using the NW.js platform for infiltrating the victims' computers, and then holding their files by encrypting them with<b style="border: 0px; font-stretch: inherit; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline;"> 128-bit AES encryption</b>.</div>

The NW.js framework not only allows for cross-platform infections but also is harder to detect because it is a legitimate framework.
