July 3 - Evidence suggests hackers breached Piriform's IT systems. As a result, we saw a significant increase in the amount of requests that were being directed at the failback DGA domains used by the malware.īelow is a simplified timeline of events, based on Avast's recent statement.

After reaching out to Avast we noted that the server was taken down and became unavailable to already infected systems. Note that in on Septemit appears that the DNS activity shifted from the DGA domain previously used in August, to the one used in September, which matches the time-based DGA algorithm described in the 'Domain Generation Algorithm' section of this blog post. The following graph shows a significant increase in the amount of DNS activity associated with the DGA domain used in August 2017 Looking at the DNS related activity observed by Cisco Umbrella for the month of July 2017 (prior to CCleaner 5.33 being released) we observed very little in the way of DNS requests to resolve the IP address for DGA domain associated with this malwareĪs mentioned earlier in this post, the version of CCleaner that included this malware was released on August 15, 2017. While most of the domains associated with this DGA have little to no request traffic associated with them, the domains related to the months of August and September (which correlates with when this threat was active in the wild) show significantly more activity. As these domains have never been registered, it is reasonable to conclude that the only conditions in which systems would be attempting to resolve the IP addresses associated with them is if they had been impacted by this malware.

If you wish to use CCleaner, as it is still technically a good program, I would advise that you always run the advanced installer and check for pre-checked options, or better still wait s week or two after the initial release of a new version and search the CCleaner Site for a Slim version (which should not contain any free addons)

The avast installer does not run if Avast is already installed so they have the code to check for existing AM products so they seem not to be concerned about the potential issues thatthey are invitingĪs I feel that this is a nefarious practice I have stopped using the Avast products including those formerly supplied by Piriform as there are alternatives that can be used Wise Disk Cleaner, Revo Uninstaller (I have Pro which includes Cleaning). Of course standard practice has always been to avoid running two active malware scanners at the same time as they are likely to cause confusion and lead to major issues, this policy by Avast invites this especially for those that do not have a lot of experience. Some cases have also been reported where there is no way to 'uncheck' the offer for the Avast Free AV package, Even if you have another competing product, which in my opinion is the act of Malware.

These 'offers' are often pre-checked so become what the AntiMalware industry, (including Avast), call PUPs, (potentially Unwanted Programs). Since this takeover the installer for CCleaner (and possibly other Piriform Products), have been reloaded with 'offers' for other Avast software. Piriform, the developers have recently been bought by Avast, The anti-Virus Company. I have stopped using CCleaner totally, my reasons are nothing to do with Malware, (well sort of ).
