- What can a hacker do with an IP address? 5 answers
I was chatting to a guy on a site, and the chat went wrong when I wrote a few wrong words by mistake. He then threatened that he will send my every detail to the vigilant team and soon my address will be known. He then showed me my IP address, the Windows version I am using, the browser, and other stuff.
What should I do now to save myself?
