Talos recently observed a case where the download servers used by software vendor to distribute a legitimate software package were leveraged to deliver malware to unsuspecting victims. For a period of time, the legitimate signed version of CCleaner 5.33 being distributed by Avast also contained a multi-stage malware payload that rode on top of the installation of CCleaner. CCleaner boasted over 2 billion total downloads by November of 2016 with a growth rate of 5 million additional users per week. Given the potential damage that could be caused by a network of infected computers even a tiny fraction of this size we decided to move quickly. On September 13, 2017 Cisco Talos immediately notified Avast of our findings so that they could initiate appropriate response activities. The following sections will discuss the specific details regarding this attack.

Don't use registry cleaners. They serve no purpose.

I have been in this business for a long time

What buisness is that? The Computer using business? The sketchy utility business?


I then turned to CCleaner as I had a lot of bloat on my system anyways and sure enough the problem was gone after one CCleaner run.


Uhmm what kinda "bloat", the kind you know you never should have used in the first place? You know what happens when you start trusting shady 3rd party fixing programs? You get malware. So you either fix the problem the right way (TM) or you get malware.
