Mozilla has asked Firefox users to update their browser to the latest version after security researchers found a vulnerability that hackers were actively utilizing to attack against users.
Browser vulnerabilities attract a lot of heat in security circles because they can be used to infect vulnerable computers often silently and without the knowledge of the user and then be used to deliver malware. Browsers are also a big target for nation-states and governments who use it for surveillance.
These vulnerability exploiting tools are also widely used by federal agents to spy on criminals, but there’s also a downside to it as the same vulnerabilities can be used by threat actors if the authorities fail to report the vulnerability to software makers. Users have been asked to update to Firefox 72.0.1 which fixes the issue. Not much information was provided about the bug except that it can take control of the affected system.
