CCleaner a widely-used tool for maintaining computer systems recently got compromised with one severe malware infection. The situation is especially embarrassing because during the summer, Avast Software the anti-virus giant of the world had bought the application.

Owing to the hack, over 2m people downloaded Piriform's infected editions that subsequently commanded the PCs for receiving directions from the hackers' regulated servers.


During attack, hackers after invading CCleaner, injected malware at one particular time when software developers at Piriform busily built the program's latest edition. Consequently, the malware received one digital certificate's signature that showed it as a supposedly genuine program. Those regularly using CCleaner had no doubt about the software upgrade which carried the malware.


In the meantime, Piriform in coordination with law enforcement snapped exchange of messages to and from its servers prior to any malevolent instructions getting detected. The development occurred after Morphisec Ltd. and Cisco Systems Inc. both security companies notified Avast about the security breach past week. News18.com posted this, September 19, 2017.


As per a report by Avast Software, 2.27m users worked with the infected application. These people had deployed v5.33.6162 onto their Windows OS of 32-bit version. Currently, there's a far lower user base of 730,000 running the v5.33.6162. Avast confirmed that end-users were all safe following deactivation of the threat. The security software developer situated in the Czech Republic, which acquired Piriform Ltd. during July, revealed the hack of maintenance tool CCleaner, September 19. According to the company, the software with dual updates that got released during August had become tainted.
