Hackers use PC clean-up tool to spread malware

Well, turns out that the state of cyber-security is only worsening by the day so much so that even anti-virus software could be hijacked to spread malware. Something similar happened recently when hackers used popular PC-cleaning software- CCleaner, owned by antivirus provider Avast to hid a malware that would operate in the background of a user's computer.

CCleaner is a popular file-clean up software available for both Mac and PC. The app features a host of tools that remove old files, clean up fragmented hard drives, and remove junk.

According to security firm, Cisco Talos, hijackers effectively "bundled" malware in with a recent version of CCleaner. The malware allows hackers to potentially get access to the user's computer, and other connected systems, to steal personal data or credentials.

The affected version of CCleaner was released on August 15 this year, with an update following on September 12. The malicious version was active in the several weeks between updates, leaving users vulnerable. According to Avast, around 2.27 million people ran the affected software, however, they were "able to disarm the threat" before it could do any harm" by sending updates of the affected version. Avast CEO Vince Steckler said that they solved the problem "within approximately 72 hours of discovery."

The firm is also working with law enforcement officials to try and identify the source of the attack.
