Twitter security team?

Anyone on the list know how to contact the Twitter Security team? Seems the new update allows an attacker to modify other people's tweets. The "Hackerone" form for reporting a vulnerability is the wrong form and the "My account has been hacked" form is also the wrong form. The whole site has been compromised, I have evidence and can't contact anyone due to the lack of an appropriate form and the fact that the security@ email address doesn't work. Thanks!
