On September 11, 2017, some customers shared their logs of the prevented attacks with Morphisec, which our team immediately started to investigate.ġ.) Inclusion of Avast reference to Morphisec help.Ģ.) The CCleaner compromised version was discovered and reported by both Morphisec and Cisco in separate in-field cases and reported separately to Avast.Īlthough the executables were signed by the original Piriform company – which was purchased by Avast in July - version 5.33 of CCleaner exhibited internal code injection behavior and reflective DLL loading directly into memory. Morphisec identified and prevented malicious CCleaner.exe installations on August 20 at customer sites. Morphisec was the first to uncover the CCleaner Hack and notify Avast. In addition, the CCleaner cloud version 1.07 was affected. ![]() According to Avast, some 2.27 million users were running the weaponized version 5.33 of CCleaner. Now it's up to you to decide what to do with CCleaner.ĪVAST CCleaner 5.45 and the telemetry thingĬCleaner 5.As widely reported today, the Avast-owned security application CCleaner was illegally modified by hackers. – Re-installs service and persistence every program open – Requires manual service kill and deletion of reg run entry – Doesn't stop/uninstall service when you de-select it Īnd to the nice 'we'll do everything differently' words from the above press release, I add the following tweet.Īlso, latest CCleaner is doing some nasty underhanded stuff: It's 2018, and yearly reminder that you still don't need CCleaner on Windows 7+. The following tweet nails it down to the point: As a Windows user, I would rather avoid such a thing. Within my blog post CCleaner 5.45 pulled and other peculiarities I 've mentioned some more peculiarities to this software. Avast also takes the opportunity to once again try to install its antivirus software on your PC. Today, Avast rolls out a new update to CCleaner which adds a number of privacy settings, and sees certain monitoring features being renamed. Within the press release they wrote a lot of privacy and what they have changed to keep the user's data private. This is a mature performance for a software that no user actually needs. CCleaner is installed more than 23 million times a month. Closing remarksįrom the above press I learned that CCleaner has been downloaded over 2 billion times worldwide (since Piriform was founded in 2004, I guess) and has about 80 million active users. Sounds good? I have shortened the rest of the press releases. These functions can only be restarted when the user activates them again. If the user deactivates Smart Cleaning, CCleaner shuts down the background processes of CCleaner, even if the program is closed and restarted. Smart Cleaning's options are now more specifically explained, making it easier for the user to choose between the available options. In the current version, the monitoring feature, which monitors the junk level of a device to initiate automatic cleaning and notifications of the user, has been renamed to "Smart Cleaning". Now a separate control for the reporting of anonymous data has been introduced in the form of a 'Privacy' tab, which users can also switch off at any time. The current version separates the transmission of anonymous usage data introduced in version 5.45 from the monitoring feature controlled by th e'Active Monitoring' checkbox. The CCleaner product collects anonymous data without personal information for statistical analysis. Piriform has published a new information sheet to help CCleaner users better understand how the software works, privacy settings options, what data is transferred and why this is necessary. ![]() In the version now published, the data settings in particular have been revised. The software cleans and optimizes computers worldwide and runs PCs at peak performance. launches V 5.46, a revised version of CCleaner. ![]() (Source: Talos) CCleaner version 5.46 should do it even betterĪfter the complete revision the CCleaner has now been released in version 5.46. At the beginning of August 2018 Piriform decided to completely withdraw version 5.45 of the CCleaner (see CCleaner 5.45 pulled and other peculiarities). This version led to a huge shit storm among users. This version came with massive telemetry data acquisition capabilities (see AVAST CCleaner 5.45 and the telemetry thing). Piriform, which was acquired in 2017 by Security provider AVAST, has released CCleaner version 5.45 a few weeks ago. ![]()
