A new Malware was revealed this week which spreads via popular performance optimization tool CCleaner was designed to target several major technology firms, it has emerged.
The initial attack affected 2.27 million CCleaner customers, meaning the collateral damage was huge.
Avast, the company which now owns CCleaner developer Periform, refused to name the targets publicly. However, a screenshot provided by Cisco Talos showed a number of domains that the attackers were looking to compromise, including ones linked to Sony, Microsoft, VMware, Vodafone, O2, Singtel, Linksys, Gmail, D-Link, Intel, Samsung, HTC and Cisco itself.
Cisco suggested this evidence reveals “a very focused actor after valuable intellectual property.”
Affected users were urged not merely to remove the CCleaner or update to the latest version, but to restore from backups or re-image systems to ensure that they completely remove both the backdoored CCleaner version and any other malware that may be on the system.
