BetaNews: Security warning: Hackers compromised CCleaner and installed a backdoor. “Users of cleanup, privacy and optimization tool CCleaner are being warned to update their software after it emerged the tool was compromised by hackers. Security researchers at Cisco Talos say that there are a ‘vast number of machines at risk.’ CCleaner is produced by Piriform, now a subsidiary of security firm Avast, making the compromise not only serious, but also embarrassing.”
