Hi dear manager, I know a cyber security team related to military in my country are working on Security holes very badly. In these days there are many trojans and viruses out there. I am using FF latest update all the time & MalwareBytes & Eset both of them licensed latest versions. Just tell me can hackers steal my passwords & cookies and logged in sessions by opening a single web site in these days? Can they install an exe file in my pc through FF in silent mode without my permission? Imagine a news web site has some malicious codes. Can they steal data through this web site by just opening it?
