Cisco’s Talos security intelligence and research group has come across a piece of software that installed backdoors on 12 million computers around the world.The software, which exhibits adware and spyware capabilities, was developed by a French online advertising company called Tuto4PC. The firm, previously known as Eorezo Group and apparently linked to another company called Wizzlabs, has been targeted by French authorities over its questionable practices regarding the installation of unwanted software and harvesting of users’ personal details.

Researchers determined that the application, installed with administrator rights, was capable not only of downloading and installing other software, such as a known scareware called System Healer, but also of harvesting personal information. Furthermore, experts found that the software is designed to detect the presence of sandboxes, antiviruses, security tools, forensic software and remote access doors.

These “features” have led Cisco Talos to classify the Tuto4PC software as a “full backdoor capable of a multitude of undesirable functions on the victim machine.”
