If you believe you're infected, check the SHA256 hash of the CCLeaner installer (and installed binaries, and DLL as well) and verify they aren't in the IOCs (Indicators of Compromise).

REDDIT CCLEANER MALWARE UPDATE

There doesn't seem to be a way to eliminate the threat, until your usual antivirus gets an update to its detection system (malware signatures). It is also worth noting that at the time of this post, antivirus detection for this threat remains very low (The detections are at 1/64 at the time of this writing). CCleaner claims to have over 2 billion downloads worldwide as of November 2016 and is reportedly adding new users at a rate of 5 million a week. The compromised version of CCleaner was released on August 15 and was undetected for four weeks. The impact of this attack could be severe given the extremely high number of systems possibly affected. According to Piriform, the malware was first discovered by Morphisec, an Israeli security company.

We confirmed that this malicious version of CCleaner was being hosted directly on CCleaner's download server as recently as September 11, 2017. During the installation of CCleaner 5.33, the 32-bit CCleaner binary that was included also contained a malicious payload that featured a Domain Generation Algorithm (DGA) as well as hardcoded Command and Control (C2) functionality. We identified that even though the downloaded installation executable was signed using a valid digital signature issued to Piriform, CCleaner was not the only application that came with the download. TALOS (Cisco's cyber sec division) reports some high profile threat that sneaked into CCLeaner 5.33: If you had CCleaner 5.33 on your machine: rollback or wipe period. ( Thanks to Cisco's Warren Mercer for confirming a few details.I will no longer reply to questions on this thread. This is a big challenge, not just for companies in a similar position, but for the security community as a whole. Without knowing anything about the inner workings of either company, it would be reasonable to assume that the security strategy of each was reflective of their respective size, rather than of the much larger footprint they had in the global IT infrastructure. It is easy to pick on Piriform and Avast (which acquired the company less than two months ago) for this serious issue, but it may be more helpful to look at the bigger picture: both Piriform and MEDoc are small companies.

This is true, as is the fact that the only data known to have been exfiltrated from infected machines was "non-sensitive", but it remains important for infected users to follow the advice from Cisco: reinstall machines or roll back to a previous version.

In an announcement, Piriform, the company that produces CCleaner, played down the seriousness of the issue, saying that only a small percentage of its users would have downloaded the malicious version (the product did not install automatic updates). Malware That Spits Cash Out of ATMs Has Spread Across the World. But it is not beyond the realms of possibility that the attackers had specific targets in mind when they spread the malware this would explain why it exfiltrated information about the infected machine. It is unclear whether this has happened, and there is no evidence to suggest that it did. However, should the attackers have used the backdoor as a foothold to install more persistent malware on an infected machine, this malware would likely still be active. The takedown of the C&C servers and the takeover of the relevant domains means that the original malware itself has now been neutralized. In a blog post, the Cisco researchers provide a good overview of the malware and its C&C communication to a hard-coded IP address, with a Domain Generation Algorithm (DGA) as a backup communication channel. Researchers from Cisco Talos found a version of the product that came with a malicious payload added to it, which installed a backdoor on targeted systems.

For the security community, 2017 might well be called the year of the update: two of the biggest security stories – the WannaCry outbreak and the Equifax breach – involved organizations being hit badly as a consequence of not having installed (security) updates, while another major story, that of (Not)Petya, concerned a threat that spread through a compromised update system used by the Ukrainian tax software MEDoc.Ī new story can now be added to the latter category: that of CCleaner, a legitimate tool widely used for cleaning up Windows and OS X computers.
