CCleaner is a free optimization tool for windows PC and Android mobile. This morning Piriform, the company which makes the CCleaner tool, divulged that specific versions of the software had been piggybacked by hackers.

Affected versions include CCleaner 5.33.6162 and CCleaner cloud 1.07.3191. The malware has a malicious data-harvesting software, compromising sensitive data of those affected.

Piriform is urging everyone to update as soon as possible, to the 5.34 version or higher. ¬†Click here for the link to the update. Users of the CCleaner cloud has been updated automatically so you don’t need to worry there!

The malware’s harvesting capabilities are known to interact with the computers name, IP address, list of installed software, list of active software, and list of network adapters (data which is described as “non-sensitive”), this information is then transferred to a third party computer somewhere in the US.

As of now, there is no other forms of information known to have been sent. The third parties server has been shut down on the 15th with the help of US law enforcement, which has helped mitigate any excess information breaches. The well known security company, Avast, as indicated that users should be safe now, and due to the quick response to shutting down the third party server, there should be little to no harm done.

An estimated 2.27 million users had the affected software installed on the windows 32-bit machines. As a follow up, no users on android devices were affected negatively by the infection.

As a form of protection and precaution for the future, Piriform is moving the entire product build environment to a more robust, secure infrastructure held by Avast.

This is the second large hacking in the past two weeks using malware that has affected millions of users. Be prepared not damage control, ensure your network is secure now before its too late! We at re2tech can help you with that! After all, we make I.T. happen!
