“We do not know if this was the same actor as before and it is likely we will never know for sure,” she wrote. Dit wil zeggen dat computers van ongeveer 20 miljoen gebruikers wereldwijd overgenomen zijn door hackers. “t is clear that this was an extremely sophisticated attempt against us that had the intention to leave no traces of the intruder or their purpose,” Baloo wrote in a blog post. Avast, which boasts of 400 million users of its products around the world, said it will study its network logs to learn more about the intrusion. Those measures, Avast CISO Jaya Baloo assured customers, were enough to ensure that CCleaner users were unaffected by the attack. Worried that the attackers would manipulate CCleaner again, Avast said it halted an upcoming release of the product, revoked its previous security certificate, and put out a security update to users. Le 13 septembre, Cisco Talos a identifié un exécutable dans le programme dinstallation de CCleaner, qui était livré aux terminaux par les serveurs de téléchargement légitimes de CCleaner. The target of the persistent attack was likely Avast’s software-cleaning tool, CCleaner - the same product that was infiltrated in an infamous 2017 supply-chain attack breach that affected over 2 million computers. Les utilisateurs de CCleaner Cloud version ont reçu une mise à jour automatique », a écrit Yung dans le billet de blog. This is PCMags first CCleaner review since the tune-up utility suffered malware-related issues in 2017. In about half of those cases, says Talos research manager Craig Williams, the hackers successfully found a machine they'd compromised within the company'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.An unidentified attacker used stolen credentials to gain high-level privileges on the network of Czech software security vendor Avast, the company said Monday. CCleaner Professional Plus is a PC-enhancing toolkit that breathes new life into. 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. CCleaner malware outbreak is much worse than it first appeared Microsoft, Cisco, and VMWare among those targeted with additional mystery payload. On Wednesday, researchers at Cisco's Talos security division revealed that they've now analyzed the hackers' "command-and-control" server to which those malicious versions of CCleaner connected. It wound up installed on more than 700,000 computers. 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's security checks. Researchers now believe that the hackers behind it were bent not only on mass infections, but on targeted espionage that tried to gain access to the networks of at least 20 tech firms. But now it's becoming clear exactly how bad the results of the recent CCleaner malware outbreak may be. An anonymous reader shares a report: Hundreds of thousands of computers getting penetrated by a corrupted version of an ultra-common piece of security software was never going to end well.
