uTorrent – one of the most popular BitTorrent apps – is vulnerable, due to multiple security flaws.

The problem was reported by the security experts from Google Project Zero team. The discovered flaws are easy to exploit, and make it possible for criminals to control key functions, including viewing downloaded files and downloading malware that will become active after PC reboot.

According to the researchers the security flaws impact a new web-based version of the uTorrent BitTorrent client, and the old (and the most popular) uTorrent Classic version.

Dave Rees, vice president of engineering at BitTorrent, claims that the bugs have now been fixed in a beta release of the uTorrent Windows desktop app and urges the users to download the newest version:

"We highly encourage all uTorrent Web customers to update to the latest available build 0.12.0.502 available on our website and also via the in-application update notification," he said in an e-mail to users.
