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. Luckily with tools like AMP the additional visibility can usually help direct attention to the initial vector. Frequently, as with Nyetya, the initial infection vector can remain elusive for quite some time. The Nyetya worm that was released into the wild earlier in 2017 showed just how potent these types of attacks can be. This trust relationship is then abused to attack organizations and individuals and may be performed for a number of different reasons. This is because with supply chain attacks, the attackers are relying on the trust relationship between a manufacturer or supplier and a customer. Supply chain attacks are a very effective way to distribute malicious software into target organizations.

Update 9/20: Continued research on C2 and payloads can be found here: There was no analysis performed on the selected addresses beyond that they could be combined to create the destination. The resulting two A record IP addresses were then assigned to the DNS configuration.
The remaining 16 random bits were combined with the remaining bits of the destination address to create the second A record. 16 bits of that were combined with 16 bits of the destination address to create the first A record. To control the connections Talos has to create two IPs such that they can be fed into the application to resolve to the sinkhole IP.ģ2 bits of random data were generated. The true destination IP is then computed and connected to. 16 bits of the true destination IP are encoded in the first A record, 16 bits are encoded in the second A recordĤ.

The company has already apologized for the incident and says it’s “taking detailed steps internally so that this does not happen again.” At the very least, it would seem adding automatic updates to all future iterations of its products, including the free ones, would go a long way toward mitigating potential future threats.Update 9/19: There has been some confusion on how the DGA domains resolve. The company says the investigation is “still ongoing.” Is there anything else Piriform needs to do? It’s not yet clear, and Piriform is declining to speculate. You can download the newest version here.
Piriform says users should update to CCleaner version 5.34 or higher. In other words, says the company, “to the best of our knowledge, we were able to disarm the threat before it was able to do any harm.” What version of CCleaner eliminates the malware? It has also contacted law enforcement and says it’s “worked with them on resolving the issue.” The company also says 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 v users to the latest version.” The company has already updated both the online and downloadable versions of CCleaner. What is Piriform doing to remedy the problem?

Piriform says it believes the 32-bit Windows version of CCleaner and version of CCleaner Cloud were modified illicitly before their release to users.Īccording to Avast, the malware attempts to transmit information like computer names, IP addresses, installed software, active running software, network adapter information and more, to a server located in the United States. Which versions of CCleaner have the malware? Regardless, if you’re running any version of CCleaner, you’ll want to ensure you’ve updated to the latest version immediately. But since the free version of the tool doesn’t appear to include automatic updates, it stands to reason that anyone running the free version is significantly more at risk, since these users would need to manually download the update. Am I at risk from malware?Īnyone specifically using the 32-bit Windows version of CCleaner is at risk. “There is no indication or evidence that any additional ‘malware’ has been delivered through the backdoor,” it added. “We believe that these users are safe now as our investigation indicates we were able to disarm the threat before it was able to do any harm,” the company said in a press statement. How many people are at risk?Īvast, the multinational cybersecurity firm that recently bought Piriform, says it believes the compromised software was installed on 2.27 million machines. After investigating further, it determined these versions were modified illicitly before their release to users. Piriform says it first detected a problem on September 12, when it noticed an unknown IP address receiving data from software found in recent versions of the software.
