I got a message on Facebook on 21.11.2017 at around 7 pm from a college junior after many years asking for a help. She then asked my mobile number and told me that her phone is not working and her mail got blocked so she needs a code from me which I received over SMS. I sent it to her thinking that she will connect to me over Gmail through this code. Then I asked her what help she requires. She said that is it. I got suspicious and checked my Gmail and realised that my password has been changed and it was being accessed through someone using windows. I has just logged into my account through phone. I immediately changed the password. But by that time more than 1.5 hours had passed by. I changed passwords of all my net banking accounts also. Then I got in touch with that girl and realised that her account was also hacked. Now I'm afraid that what was hacker's intention and what he/she might do in future. Thanks Mehak
