The newly discovered malware is called " Trojan Yontoo.1 ", warned by Russian security company Doctor Web . According to Slashgear , hackers can trick users into installing plugins into browsers to enable trojans in a variety of disguised ways, for example, plugins for watching movies or even download accelerators.

When enabled, Trojan.Yontoo.1 will ask users to install a software called ' Free Twit Tube ' or similar. If the user clicks agree, the trojan will download and install the malicious code into a web browser such as Chrome, Firefox and Safari.

Then, every time the user browses the web, all the information they use will be sent to the remote server, and the server will send the data to help the trojan can attach malicious code to the website the victim is viewing.
