Redl is another notorious virus that arises from family of STOP ransomware. This computer threat usually targets common user’s files such as documents, spreadsheets, databases, archives, images, drawings, and many more. The objective is to encrypt the files with complex algorithm and then, append them with .redl extensions. Via this method, attackers were able to lock the files and disassociate them with any applications, which denying user’s access to their very own data.

Computers may get infected with Redl ransomware in so many ways. But it was observed that this threat spreads mainly via the internet with means of reaching victims quickly via spam email messages. Authors of Redl are running a mass-mailing campaign that automatically sends the virus to random recipients collected from previous attacks or tons of email addresses being sold by cyber criminals in dark part of the web.

Attackers easily deceived email recipient by creating fake messages purportedly from reputable company or organization. The content messages are in the same pattern, which asks recipient into opening the attached file claiming that full information is inside the document.

Another way that people behind Redl ransomware uses to spread the virus is through file-sharing networks. In this technique, the malicious code is embedded into freeware and shareware and uploads them to insecure servers where users normally download free applications. The mentioned deployment scheme is the same technique that attackers apply to spread older variants as Piny, Nbes, Mkos, and many more.

The execution of Redl ransomware on the computer is not only limited to encryption of files. It also renders the system unstable due to several malicious files integrated onto Windows system that interferes with normal operation. Redl can block access to security sites aiming to prevent victims from downloading removal tools and recovery software. Files that allows Redl to communicate to remote server for further update was also reported to be embedded on the system.
