The Cdr ransomware is a cryptovirus programmed to encode personal data.

Cdr Virus (STOP Ransomware) – Detailed Description

Analyses of Cdr viru samples indicate that the infection belongs to the well-known

STOP ransomware family. Strains of this threat family have been circling around the web since the end of 2017.

According to security researchers reports, the Cdr STOP ransomware is lurking across the web in active attack campaigns. The attacks can be set against online users worldwide. As of the spread techniques used for the delivery of Cdr malicious samples, they are likely to be malspam, corrupted web pages, software installers, P2P networks and others.

When executed on a target machine the Cdr virus triggers a long sequence of malicious operations that support system security disruption. By affecting system registries, ending essential processes and activating malicious files, the ransomware becomes able to reach the target types of personal files and transform them with the help of two sophisticated cipher algorithm – AES and RSA. To make victims more prone to pay a ransom fee, Cdr virus corrupts files that are likely to store valuable personal information.
