All of this happened on 18th November 2020
A person I know sent me a phishing link of Facebook then Google, I entered my credentials however as soon as I found out that its a phishing link, I turned off my mobile WiFi and switched it off and I changed my Google Password immediately from another device which was my iPad, I didn’t change my Facebook password because it didn’t have any information of myself at all, but somehow he got to know my Instagram tag which he claimed to have got to known through Facebook but I never linked it, It just had the same email as my Instagram, so the only way he could’ve got to know my Instagram is if he had my Gmail account.
I downloaded the Google Data of my account and checked the login history of my account
It didn’t show any other IP addresses or other devices rather than mine, there were 4 forgot passwords made on my Instagram which I got through mail but when I checked my Instagram logins there wasn’t any other login either (other than my devices and IP addresses) and my Gmail didn’t have less secure app access turned on
When I booted my Mobile Phone again, the one where I opened the phishing link, I downloaded Bitdefender security and scanned my device and it didn’t find any malware. The browser I used was a Hidden Calculator Browser, the guy who phished claimed that he used Social Engineering Toolkit first when he phished for Facebook and it didn’t work so he tried phishing Google using HiddenEye and it worked.
I did an Nmap scan on my PC and it found an open port number 4445 named upnotifyp but this was only internal because when I told my friend to scan there was no open port on my IP address and I downloaded Avast WiFi inspector on my PC scanned my WiFi and Router and it said no vulnerabilities detected.
Im having severe anxiety since weeks because my Google Photos had sensitive pics which were supposed to be my eyes only but I don’t know whether he logged in or not because there was no IP address or device other than mine in Google Login History but he got to know my Instagram tag when it wasn’t linked to Facebook, but he claimed to get it through Facebook, my Facebook and Insta only shared the same email ID and theres no other way he could’ve got to know my Insta other than having access to my mail, but then again there were no other IP addresses and I can guarantee that this person wasn’t using my WiFi, please help me out.
