Hackers backdoored the popular CCleaner Windows utility. Two malware-tainted versions collected computer names, IP addresses, lists of installed and active software, as well lists of network adapters before sending the data to the attackers server. A cloud version released in August was similarly infected. Avast says an estimated 2.27 million systems installed the infected versions. Affected systems need to be restored to a state before August 15, 2017, or reinstalled. Users should also update to the latest available version of the utility to avoid infection.”]
