In this case, the attackers used the keylogger functionality and other analysis features to burrow deep into Piriform's development and distribution systems. The attackers installed malware called ShadowPad, sort of customizable malware platform that can be used for an assortment of attacks from DDoS to keylogging, on the compromised computers. From there, the attackers moved laterally to a second computer, always working outside office hours when it was unlikely that people would be using the machines. Hackers initially got onto Piriform’s London networks by using stolen credentials to log into a TeamViewer remote desktop account on a developer PC.

"As a threat research organization we do analysis like this on a daily basis, it's right in our core competency, so it was sort of ironic to suddenly be in the business of forensically analyzing our own attack." It was an unexpected surprise gift we got as part of the acquisition," Vlcek told WIRED ahead of his talk at RSA. "This thing was a bit, shall we say, black. But the specter of supply chain attacks is difficult to shake. Vlcek says that Avast's quick response and existing goodwill toward CCleaner-which has a sometimes cultish online following-has allowed Avast to learn from the incident and better protect its users. By September, it knew it had a massive security crisis on its hands. On March 11 of last year, attackers compromised the systems Piriform, the company that created CCleaner.

The incident exposed millions of computers and reinforced the threat of so-called digital supply chain attacks, situations where trusted, widely distributed software is actually infected by malicious code.Īt the RSA security conference in San Francisco on Tuesday, Avast executive vice president and chief technology officer Ondrej Vlcek walked through a post-mortem of the attack, which ultimately led to 2.27 million downloads of the corrupt CCleaner version. The software updates users were downloading from CCleaner owner Avast-a security company itself-had been tainted with a malware backdoor.

I'll update this answer with more details as they come in, but for now, that's all we get as outsiders.In September, security researchers at Cisco Talos and Morphisec made a worst nightmare-type disclosure: the ubiquitous computer cleanup tool CCleaner had been compromised by hackers for more than a month. Detecting these threats before they can do real damage is more difficult than it looks though. They could've smuggled in their backdoor through larger commits in internal systems (guessing here) where they'd have likely gone unnoticed once a developer signed off on the code, or they could have patched the binaries themselves on the update server after stealing the signing certificate (which seems more likely). Well, once you've got access to a system, that part is definitely much easier. But how about actually backdooring the code? So far, we've only looked at how someone might've broken into the production servers. In the light of their blog post that claims that the attack was an APT, I'm leaving out other possible vectors such as 'It was an inside job' - the target seems to have been much larger and it's unlikely to have been as small as this might otherwise imply.
