    CCleaner Hacked


    CCleaner Hacked - Malware Spread to 2.2 Million Users - MajorGeeks

    Here is the official summary and apology:

    "We would like to apologize for a security incident that we have recently found in CCleaner version 5.33.6162 and CCleaner Cloud version 1.07.3191. A suspicious activity was identified on September 12th, 2017, where we saw an unknown IP address receiving data from software found in version 5.33.6162 of CCleaner, and CCleaner Cloud version 1.07.3191, on 32-bit Windows systems. Based on further analysis, we found that the 5.33.6162 version of CCleaner and the 1.07.3191 version of CCleaner Cloud was illegally modified before it was released to the public, and we started an investigation process. We also immediately contacted law enforcement units and worked with them on resolving the issue. Before delving into the technical details, let me say that the threat has now been resolved in the sense that the rogue server is down, other potential servers are out of the control of the attacker, and we’re moving all existing CCleaner v5.33.6162 users to the latest version. Users of CCleaner Cloud version 1.07.3191 have received an automatic update. In other words, to the best of our knowledge, we were able to disarm the threat before it was able to do any harm.

    Technical description
    An unauthorized modification of the CCleaner.exe binary resulted in an insertion of a two-stage backdoor capable of running code received from a remote IP address on affected systems.

    The malware was also programmed to collect a bunch of user data, including:

    Name of the computer
    List of installed software, including Windows updates
    List of running processes
    MAC addresses of first three network adapters
    Additional information whether the process is running with administrator privileges, whether it is a 64-bit system, etc.

    Talos’ report warns that the malware was found in CCleaner version 5.33, which was actively distributed between August 15 and September 12. What is particularly jarring is that it appears the infected app was signed with a valid certificate Symantec issued to Piriform (recently acquired by Avast)."


    Be sure to update your CCleaner immediately with version 5.34.6207 or better yet, get a better drive cleaner and replace it with Wise Disk Cleaner. It would also be a good idea to scan your system with a trusted application like Malwarebytes.

    This is CC Pro version.

    For some easier ID'ing if you've been infected, search in HKEY_LOCAL_MACHINE\SOFTWARE\Piriform\CCleaner\Agomo for the following keys values
    - MUID: randomly generated number identifying a particular system. Possibly also to be used as communication encryption key.
    - TCID: timer value used for checking whether to perform certain actions (communication, etc.)
    - NID: IP address of secondary CnC server
    If they are present, you're infected!

    Addionally, the Agomo key should not be present in your registry.

    HUMPH! My complaint about the last CCleaner update installing AVAST even after I declined pales in comparison to this.

    Probably a good idea.

    Are there any possible downsides to that?

    Wondering if Speccy is next?

    A buyout by Avast can't be good in the long run. Maybe a reduction in the features of the free versions as they attempt to get paid for their buyout.

    Speccy isn't as well known as ccleaner so there won't be so many victims for them.
