"This is professional quality, well-made software. Whoever was behind the attack was well funded and very focused on what they wanted. However that number is likely much higher, “at least in the order of hundreds,” the blog post said.

On Thursday it said it now has evidence that it was sent to 20 machines in eight companies. Those "fish" were then hit with a second piece of malware that was hidden in the first.Īvast had seen the second malware but originally believed that it hadn't been delivered to any customers. "It was kind of like a fisherman throwing his line in the water but only keeping the fish he wanted," said Craig Williams, senior technical leader at Cisco Talos. The attackers assembled all that in a database, which then chose a tiny number of specific targets out of the mix.

Once on a PC, the malware "called home" to the computer that was controlling it, sending information about the machine's Internet Protocol address, its users, the administrator who controlled it and what software was running on it. Talos researchers said of the 2.3 million computers infected with the tainted CCleaner software, more than 700,000 had reported back to the attackers’ servers over the course of the four days Talos researchers were able to track.īut that wasn’t the real thrust, they believe. "At the time the server was taken down, the attack was targeting select large technology and telecommunication companies in Japan, Taiwan, UK, Germany and the U.S.," Avast CEO Vince Stickler and Ondřej Vlček, general manager of Avast's consumer business unit, wrote in a blog post Thursday.Ĭleaner was created by London-based Piriform, which was acquired in July by Avast, a Czech Republic-based security software maker. Hackers had hidden malware in CCleaner, a popular app meant to clean out cookies and junk programs from PCs and Android phones to make them run faster, according to Avast, owner of the app.īut there was a deeper and more insidious attack going on underneath.Īn in-depth analysis first disclosed late Wednesday by Cisco Talos, the security research arm of San Jose, Calif.-based Cisco, found the malware contained a hidden "attack within the attack" that specifically targeted large tech companies, possibly to do commercial or state-level espionage.Īvast, owner of the CCleaner app, concurred. The initial hack was reported on Tuesday. “Piriform believes that these users are safe now as its investigation indicates it was able to disarm the threat before it was able to do any harm,” says an Avast spokesperson.SAN FRANCISCO - That 2.3 million CCleaner app hack reported Tuesday? It turns out the actual end goal may have been a few dozen high-value targets in the tech industry, an example of the lengths sophisticated attackers will go to to gain access to potentially valuable data.

2.27 million users have been affected by the attack, and Avast Piriform believes it was able to prevent the breach harming customers. Dubbed “crap cleaner,” it’s designed to wipe out cookies and offer some web privacy protections. “For a period of time, the legitimate signed version of CCleaner 5.33 being distributed by Avast also contained a multi-stage malware payload that rode on top of the installation of CCleaner,” says the Talos team.ĬCleaner has been downloaded more than 2 billion times according to Avast, making it a popular target for hackers.

Security researchers at Cisco Talos discovered that download servers used by Avast (the company that owns CCleaner) were compromised to distribute malware inside CCleaner. Hackers have successfully breached CCleaner’s security to inject malware into the app and distribute it to millions of users.
