For developers and software companies, the attack on CCleaner is a reminder of the importance of securing every link of the download supply chain. Like any security decision, this is a trade-off: for every attack that might take advantage of the supply chain, there are one hundred attacks that will take advantage of users not updating their software.įor users, sticking with trusted, official software sources and updating your software whenever prompted remains the best way to protect yourself from software attacks. This and other supply chain attacks should not deter users from updating their software.

But the hackers appear to have penetrated Avast’s download servers before the software update was signed, essentially hijacking Avast’s update distribution process and punishing users for the security best practice of updating their software.ĭespite observations that these kind of attack are on the rise, the reality is that they remain extremely rare when compared to other kinds of attacks users might encounter. Software updates like the one Avast released for CCleaner are typically signed with the developer’s un-spoof-able cryptographic key. Supply chain attacks undermine users’ trust in official sources, and take advantage of the security safeguards that users and developers rely on. The harms of this hack extend far beyond the 2 million users who were directly affected. The goal should be to secure internal development and release infrastructure to that point that no hijacking, even from a malicious actor inside the company, can slip through unnoticed. This means that developers need to get in the practice of “distrusting” their own infrastructure to ensure safer software releases with reproducible builds, allowing third parties to double-check whether released binary and source packages correspond. As more and more users get better at bread-and-butter personal security like enabling two-factor authentication and detecting phishing, malicious hackers are forced to stop targeting users and move “up” the supply chain to the companies and developers that make software. This is often called a “supply chain” attack, referring to all the steps software takes to get from its developers to its users. Avast has advised CCleaner Windows users to update their software immediately. Even worse, CCleaner’s popularity with journalists and human rights activists means that particularly vulnerable users are almost certainly among that number. Avast estimates that over 2 million users downloaded the affected update. Download servers at Avast, the company that owns CCleaner, had been compromised to distribute malware inside CCleaner 5.33 updates for at least a month.

Yesterday, Cisco’s Talos security team uncovered just that kind of attack in the computer cleanup software CCleaner. Some of the most worrying kinds of attacks are ones that exploit users’ trust in the systems and softwares they use every day.
