Backdoor Found in CCleaner: Reinforces the Need for Better Data Protection

Users of CCleaner for Windows, a maintenance and file clean-up tool developed by Avast Piriform, are being told to update their software immediately, since it’s been discovered that hackers had installed a backdoor in the official application that would allow additional malware to be added to the infected system.

On September 13, researchers at Cisco Talos found that downloads of CCleaner 5.33 and CCleaner Cloud 1.07.3191 contained more than just the official free versions – a domain generation algorithm (DGA) and hardcoded Command and Control function was incorporated into the software. That means hackers somehow gained access to the official development process and implanted malware designed to steal data from the product’s two million users.

Yes the 5.35 (and 5.34) version of ccleaner is without trojan. More information at this thread https://forum.piriform.com/index.php?showtopic=48869

 

ADVICE FOR USING CCleaner'S REGISTRY INTEGRITY SECTION

DON'T JUST CLEAN EVERYTHING THAT'S CHECKED OFF.

Do your Registry Cleaning in small bits (at the very least Check-mark by Check-mark)

ALWAYS BACKUP THE ENTRY, YOU NEVER KNOW WHAT YOU'LL BREAK IF YOU DON'T.
