The tool was installed on the four Piriform computers on April 12th, 2017, while the preliminary version of stage two had been installed on the computers on March 12th, 2017. ShadowPad is a cyber attack platform that cybercriminals deploy in victimsвЂ™ networks to gain remote control capabilities, and has been analyzed in the past. We consolidated and inspected the Piriform infrastructure and computers, and found preliminary versions of the stage one and stage two binaries on these, and we found evidence of a specialized tool, ShadowPad, which is used by a specific group of cybercriminals, installed on four Piriform computers. To eliminate the threat from the Piriform network, we migrated the Piriform build environment to the Avast infrastructure, replaced all hardware and moved the entire Piriform staff onto the Avast-internal IT system.

However, we have found evidence of activity that could indicate what the intended third stage of the attack could have looked like. Up until now, we donвЂ™t have any evidence that a third stage binary has been downloaded onto the affected computers.

The first stage included downloader capabilities, which were used to download a second stage binary onto just 40 PCs out of the millions of devices infected with stage one, making it a highly targeted attack. The first stage of the malware was designed to collect non-sensitive information from CCleaner users, including, for example, name of the computer, list of installed software, and a list of running processes. The malware was introduced to the build server of Piriform, the company developing CCleaner, some time between March 11 and July 4, 2017, prior to AvastвЂ™s acquisition of Piriform on July 18, 2017.

The altered installation file was downloaded by 2.27 million CCleaner customers worldwide.

To recap, on September 18, 2017, we disclosed that CCleaner had been targeted by cybercriminals, in order to distribute malware via the CCleaner installation file. Activity was found in Piriform network although not on any of the CCleaner customersвЂ™ PCsДЇollowing the CCleaner incident last year, we have continued to investigate what happened and have shared our latest insights at the Security Security Analyst Summit today.
