Hackers backdoored CCleaner for a month: Over 2 million infected with malware

September 18, 2017 – 9:51 AM

Hackers backdoored the popular CCleaner Windows utility; for nearly a month, 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 attacker’s server.

Cisco Talos, which discovered the malware on September 13 while a customer was beta testing new exploit detection technology, warned that the tainted versions of CCleaner were being distributed for nearly a month. CCleaner 5.33 was released on August 15 and a newer version without compromised code wasn’t released until September 12. A cloud version released in August was similarly infected.
