Random idea : We can use XSS to exfiltrate passwords by abusing password managers autofill functionality. What we can do is inject a fake login page which gets filled up by a password manager like @LastPass , and our xss can steal them.

Hello @chesscom , I've found a critical vulnerability in your system. Please check the report in your security bug ticketing system.


We've wrapped up our fifth onsite @hackthebox_eu meetup Nepal. It was organized in collaboration with women in cybersecurity for the women's cyber empowerment. We solved a Windows machine to get them started with CTF. Thanks @hackthebox_eu , and my team mates @maskop9 @tnirmalz.

We've wrapped up fourth @hackthebox_eu meetup Nepal. It was an onsite event hosted for the college students. There were around 100+ participants and it was so overwhelming. We solved a medium level box named "interface". Looking forward to upcoming events. Keep hacking !
