This came after security researchers at Cisco Systems Inc CSCO.O and Morphisec Ltd alerted Piriform's parent Avast Software of the hack last week. Piriform said it worked with law enforcement and cut off communication to the servers before any malicious commands were detected. More than 2 million people downloaded tainted versions of Piriform’s program, which then directed the computers to get instructions from servers under the hacker’s control, Piriform said.

This article was amended on 20 September to remove references to CCleaner as an “anti-malware program”.

Notoriously, a successful hack on Ukrainian accounting software MeDoc was responsible for seeding the NotPetya “ransomworm” – a self-replicating piece of ransomware – that took down companies including Merck, Maersk and Cadbury’s. In March 2016, a compromised version of BitTorrent client Transmission spread ransomware on Macs for three days, the first functioning ransomware attack on the operating system. The method, known as a “supply chain” attack, works because “the attackers are relying on the trust relationship between a manufacturer or supplier and a customer”, Talos says. Talos recommends that affected systems be restored “to a state before August 15, 2017, or reinstalled”, advice which Piriform does not repeat.Ĭompromising downloads to trusted software is an increasingly common route by which malware authors infect devices. The breach was independently discovered by Cisco’s Talos Intelligence research team, who notified Piriform on 13 September, one day after the clean version of the software had been released in a regularly scheduled update. By taking down the “command and control” server, Piriform may have prevented the infection being used to inflict further damage.

The company says 2.27m users were infected, but added that “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”. “At this stage, we don’t want to speculate how the unauthorised code appeared in the CCleaner software, where the attack originated from, how long it was being prepared and who stood behind it,” the company’s vice president, Paul Yung, said. The data, according to Piriform, included “computer name, IP address, list of installed software, list of active software, list of network adapters”.Īs well as the data leak, however, the infection also resulted in a “second stage payload” being installed on to the affected computer – another piece of malware, which Piriform says was never executed.

In that period, a trojan was loaded into the download package which sent “non-sensitive data” from infected users’ computers back to a server located in the US.
