It had been a long fortnight and i have not finished writing my report for various banks. It was really that much report to write and especially for one specific particular bank. I managed to bypass the security control mechanism setup by this bank and steal the username and password of any user.
Most of the banks here in Singapore practised two factor authentication and for most people, they think that it is secure because of the extra added security. However, a PoC was released to the bank depicting to them that it was possible to bypass the security control mechanism and it was possible to capture the username and password of any user. I am sorry guys, i am not supposed to leak out any information here. It is very sensitive from the bank's point of view. The best part of the exploit was there was no XSS or sql injection or any sorts of vulnerability that facilitate this exploit. It was purely just information gathered during the passive information gathering exercise.
I was browsing their site and i discovered a section where some information could help me facilitate the research of writing the exploit. I had an albeit pedantic thought when i saw that particular section. I was thinking that with all that information, i am definitely able to bypass the security mechanism. However to do that, i would require someone else to write the code for me with my ideas. Nevertheless, within a week, i managed to come out with a PoC and display a great deal of demostration. Guys, i know you want to know the details, but i simply can't reveal anything because of the Non Disclosure Agreement I signed. All i can say is passive information gathering is a very important exercise when trying to attack huge organizaton and guys can spend hours and days writing a cool exploit, with me, all i need is total observation and i got the results i want with ease. Why bother to go all the way to do something difficult when something easy can be accomplished faster??
I would love to attach a screenshot of what i managed to captured, but then again, it is too sensitive. I am sorry, but just know that it is possible to bypass 2FA.
