...AFAIK when the 2FA option is enabled you don't receive email links to confirm your withdrawal requests...
If what you are saying is true then my freebitco.in account could be more vulnerable to an attack with 2FA enabled.
When 2FA was NOT enabled I was simply able to ignore the unauthorised payment request confirmation email and the bitcoin was refunded back to my account after an hour.
It's important to keep in mind that I had NOT made a payment request, so the attackers were able to trigger a payment request without any action on my part.
This happened immediately after I received an email notification that I had won tenth place in the referral wagering contest. I believe the attackers may have been using the wagering contest results to target contest winners.
Only after changing my password and enabling 2FA did I attempt a withdrawal. The attackers somehow managed not only to change the destination Bitcoin address, but also the withdrawal amount. Additionally, it seems they were able to hide the pending withdrawal notification on the freebitco.in site.
In summary, the attackers can hijack or trigger a payment request with or without any user interaction. They can set or change the destination Bitcoin address and the withdrawal amount with or without any user interaction. With 2FA enabled we do not receive a payment request confirmation email.
Note that if the attackers can change a withdrawal destination address then it is likely that they can also change a deposit destination address too.
Given the current situation, it is no longer safe to deposit or withdraw from freebitco.in
It may seem that my account could be less vulnerable with 2FA disabled as long as I do not attempt a withdrawal or confirm any unauthorised payment requests.
Without any further advice from support I am tempted to consider that my account may be more secure with 2FA disabled. However, this may allow the attackers to change my email or other personal info on my profile.
I'm damned if I do and damned if I don't.
The same thing that happened to @BayAreaCoins also happened to me. I responded to the situation exactly as he did
Until this situation is resolved and in light of other forum topics talking about the possibility that the freebitco.in html code has been infected with a malicious JavaScript (cash travel) I think my only option at this stage is to go to site settings and block JavaScript.
Unfortunately, with JavaScript disabled, i am unable to do anything with the site. The site menu doesn't work. The faucet doesn't work. Nothing works.
I don't have the tools, knowledge or skills to sniff packets, but I'm sure there are members and developers on this forum that do
