CCleaner Hack May Have Been A State-Sponsored Attack On 18 Major Tech Companies

At the beginning of this week, reports emerged that Avast, owner of the popular CCleaner software, had been hacked. Initial investigations by security researchers at Cisco Talos discovered that the intruder not only compromised Avast’s servers, but managed to embed both a backdoor and “a multi-stage malware payload” that rode on top of the installation of CCleaner. That infected software — traditionally designed to help scrub PCs of cookies and other tracking software and malware — was subsequently distributed by Avast to 700,000 customers (initially, that number was thought to be 2.27 million).And while that’s all notably terrible, it appears initial reports dramatically under-stated both the scope and the damage done by the hack. Initially, news reports and statements by Avast insisted that the hackers weren’t able to “do any harm” because the second, multi-stage malware payload was never effectively delivered. But subsequent reports by both Avast and Cisco Talos researchers indicate this payload was effectively delivered — with the express goal of gaining access to the servers and networks of at least 18 technology giants, including Intel, Google, Microsoft, Akamai, Samsung, Sony, VMware, HTC, Linksys, D-Link and Cisco itself.
