If you are using Internet Explorer, switch browsers immediately. The HP Zero-Day Initiative (ZDI) security division has just published four critical zero-day vulnerabilities (ZDI-15-359, 360, 361 and 362).
HP's ZDI security division has a policy that states that researchers must notify vendors when they discover vulnerabilities in their product, but gives them 120 days to fix the bugs.
If they don't fix them, they will publish the zero-days on the internet, with the aim of mobilizing the company that is indifferent to protecting the public.
According to the information reported by the ZDI department, all vulnerabilities allow remote code execution and attackers could gain the same privileges as logged in users.
What is very important to know is that attackers will have to convince you to click on a malicious link. If you don't, you will be completely safe.
In some cases, however, they might use other scripts and tricks to get you to click on the link.
So security experts recommend that you stop using Internet Explorer immediately until Microsoft fixes the security vulnerabilities.
