Security researchers at Cisco Talos discovered that download servers used by Avast (the company that owns CCleaner) were compromised to distribute malware inside CCleaner. \u201cFor 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,\u201d says the Talos team.<\/p>\n<p>CCleaner has been downloaded more than 2 billion times according to Avast, making it a popular target for hackers. Dubbed \u201ccrap cleaner,\u201d it\u2019s designed to wipe out cookies and offer some web privacy protections. 2.27 million users have been affected by the attack, and Avast Piriform believes it was able to prevent the breach harming customers. \u201cPiriform 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,\u201d says an Avast spokesperson.<\/p><\/blockquote>\n<p>Source: <a href=\"https:\/\/www.theverge.com\/2017\/9\/18\/16325202\/ccleaner-hack-malware-security\">The Verge<\/a><\/p>\n<script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3033787195489589\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<!-- Darknet Responsive Post Ad Links [previously link ad unit] -->\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-client=\"ca-pub-3033787195489589\"\r\n     data-ad-slot=\"5456620019\"\r\n     data-ad-format=\"auto\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script>\n<p>This CCleaner Hack is a fairly advanced attack with some people making links to the Chinese government, an attack of this scale and focus does feel like a nation-state attack. There is some code reuse from the Group 72 also known as Axiom who are linked to the Chinese Government.<\/p>\n<p>Some of the configuration files are also set in China&#8217;s time zone, which whilst it does indicate it probably is from China &#8211; it doesn&#8217;t link it for certain to the government.<\/p>\n<blockquote><p>Earlier this week, security firms Morphisec and Cisco revealed that CCleaner, a piece of security software distributed by Czech company Avast, had been hijacked by hackers and loaded with a backdoor that evaded the company&#8217;s security checks. It wound up installed on more than 700,000 computers. On Wednesday, researchers at Cisco&#8217;s Talos security division revealed that they&#8217;ve now analyzed the hackers&#8217; &#8220;command-and-control&#8221; server to which those malicious versions of CCleaner connected.<\/p>\n<p>On that server, they found evidence that the hackers had attempted to filter their collection of backdoored victim machines to find computers inside the networks of 20 tech firms, including Intel, Google, Microsoft, Akamai, Samsung, Sony, VMware, HTC, Linksys, D-Link and Cisco itself. In about half of those cases, says Talos research manager Craig Williams, the hackers successfully found a machine they&#8217;d compromised within the company&#8217;s network, and used their backdoor to infect it with another piece of malware intended to serve as a deeper foothold, one that Cisco now believes was likely intended for industrial espionage.<\/p><\/blockquote>\n<p>Source: <a href=\"https:\/\/www.wired.com\/story\/ccleaner-malware-targeted-tech-firms\/\">Wired<\/a><\/p>\n<p>And as a user, it means you should be careful.
