Consider this my opinion on the latest vulnerability discovered in ICICI's Internet Banking portal that allows anybody to read your bank statement without logging in to your account. Yeah, you read that right, "without" logging in...
OK, A friend of mine pointed out this vulnerability to me... Initially my impression was well it must be another SQL injection as I have always been skeptical about the level of security on the Internet provided by private & public banks.

Disclosed by NDTV to ICICI Bank because the bank didn't bother checking that researcher's email as usual. So much for having those abuse / info e-mail addresses on their website. The banks must start to consider working on a middle-ground with security researchers.
Initially the vulnerability seems innocuous but, when you factor in that a vulnerability like this could lead to money being stolen or could lead to internet fraud. Imagine 20 lakhs get stolen from your bank account straight up by a guy who cons you with an internet scam. Then try to look at this vulnerability in this new light with your money on the table... Scary? Yeah I thought so! ;)
New Delhi-based cyber-security consultant Dominic K. spoke to NDTV Gadgets and discussed the multiple layers of security that banks have in place, which include multi-factor authentication, encryption, secure connectivity - SSL and HTTPS and identity management systems. He added, "We have not heard of any serious attacks that were successful. These are industry practices that meet global standards."SSL - Broken many times
HTTPS - Broken - Can be stripped and/or hijacked
Certificates can be spoofed and/or stolen
How multi-factor authentication or secure connectivity will help when there's no user logged in?
Authentication is the mechanism where a user logs-in to confirm the his / her identity on the bank's website. This is usually achieved with parameters such as Debit card no, Account no, Debit card PIN or Username / Password issued for Internet banking. The authentication mechanism is NOT part of this vulnerability so, all those global standards don't matter in this case.
Our high school teachers have spoiled us by with an example for every damn thing in the world.
