“Working with US law enforcement, we caused this server to be shut down on the 15th of September before any known harm was done. “We have no indications that any other data has been sent to the server. CCLEANER MALWARE THE HACKER NEWS SOFTWAREThat data includes the user’s computer name, IP address, a comprehensive list of installed software on their machine, a list of active software, and list of network adapters. Hackers appear to have used the malware to harvest what the firm describes as “non-sensitive” data. So far Piriform has been able to ascertain that the malware was communicating with a Command and Control (CnC) server located in the US. We also immediately contacted law enforcement units and worked with them on resolving the issue.” "Non Sensitive" Data Stolen “We found that the version of CCleaner and the version of CCleaner Cloud was illegally modified before it was released to the public, and we started an investigation process. CCLEANER MALWARE THE HACKER NEWS CODEIt is not yet known how hackers managed to hide the malevolent code within the official version of CCleaner. However, other CCleaner users may still be running the compromised version, so updating manually is extremely important for those consumers. ![]() CCLEANER MALWARE THE HACKER NEWS UPDATEIt is worth noting that users of CCleaner Cloud will have received the update automatically. ![]() Piriform is urging all CCleaner users to download version 5.34 or higher as soon as possible. Piriform says that the versions of its software that were compromised are CCleaner and CCleaner Cloud. Since then, research from Cisco has revealed that the true number of infections is lower, at around 700,000 PCs.Īccording to the blog post by Piriform, infected copies of CCleaner were disseminated between 15 August and 12 September. CCLEANER MALWARE THE HACKER NEWS PCSince the story first broke, the computer security firm Avast has announced that up to 2.27 million CCleaner users may have been affected by the malware that was hidden within official versions of the popular PC performance optimization software. The good news is that only people running the CCleaner on 32-bit Windows systems were affected. The revelation first hit the web on Monday morning, when the software’s developer Piriform published a blog post on the subject. CCLEANER MALWARE THE HACKER NEWS ANDROIDOnly the cloud version could be updated automatically to remove the bad code.News has emerged that an infected version of the popular PC and Android optimization software CCleaner has been spreading malware to large numbers of computer users. A new, uncompromised version of CCleaner was released the same day and a clean version of CCleaner Cloud was released on Sept. Piriform said that Avast, its new parent company, had uncovered the attacks on Sept. A spokeswoman said that 2.27 million users had downloaded the August version of CCleaner while only 5,000 users had installed the compromised version of CCleaner Cloud. ![]() It advised users of CCleaner v and CCleaner Cloud v to download new versions. In a blog post, Piriform confirmed that two programs released in August were compromised. “There is nothing a user could have noticed,” Williams said, noting that the optimization software had a proper digital certificate, which means that other computers automatically trust the program. Talos researcher Craig Williams said it was a sophisticated attack because it penetrated an established and trusted supplier in a manner similar to June’s “NotPetya” attack on companies that downloaded infected Ukrainian accounting software. At the time of the acquisition, the company said 130 million people used CCleaner.Ī version of CCleaner downloaded in August and September included remote administration tools that tried to connect to several unregistered web pages, presumably to download additional unauthorized programs, security researchers at Cisco’s Talos unit said. The malicious program was slipped into legitimate software called CCleaner, which cleans up junk programs and advertising cookies to speed up devices.ĬCleaner is the main product made by London’s Piriform, which was bought in July by Prague-based Avast, one of the world’s largest computer security vendors. 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.
