A popular tool for cleaning your PC, CCleaner, was hacked to distribute malware directly to its users.

The app is designed to clean up your system for enhanced performance and was infected with a malicious payload that made it possible to download and execute other suspicious software.

Developers, such as Piriform and Avast, have confirmed the attack but luckily there is currently no evidence that the exploit was used to install additional malware. The malware was also programmed to collect user data such as: name of the computer, list of installed software, list of running programs and additional information about the system.

Cisco Talos reports the malware-version of CCleaner was downloaded by 2.27 million users. This report states that the malware was found in CCleaner version 5.33, which was distributed between August 15 and September 12.

If you think you’re one of users that downloaded the infected version of CCleaner, visit the Piriform website and update to the latest version of CCleaner.
