Guys rhe issues is not about the password.

The real issue is that our bank information has been leaked , they do not use cimbclicks to hack your money but just through your card info link to paypal.

If it’s not about the password, then why implement the captcha?

Be safe than sorry

I already said, cimb have its fault.

but paypal allowed this to happen. I have 3 other banks in my paypal and they are also treated the same as cimb cards.

You want to blame paypal you go ahead and spam their emails or open up another thread

From some analysis it seems
- hacker create a paypal account n link it to the victim cimb debit card
- it seems it only effected cimb debit card
- paypal transfer/payment does not require sms/otp for debit card linkage
- so hacker should be able to find a loophole or hacking the cimb part that they able to obtain the latest debit card transaction
- to link a debit card in paypal, paypal will debit/credit a small amount of money to the debit card with a 4 pin code for activation
- the hacker requires this 4 pin code to add the debit card into the paypal account
- so highly likely they able to find a loophole to get this latest transaction statement with the attached information as pin code
- and this loophole seems to happen for cimb only, as from the reported case

fixing the cimb webpage with a recaptcha wont solve the prob imo, it's a loophole y paypal can be linked to cimb debit card to begin with!

Exactly

So it is advisable to transfer out all of your money while you still can

Ermmmm. They spoof js var for timestamp and server side never validates and keep track of requests? So that's how they brute force?

Stateless server side request processing? If true, I really don't know what to say....

hence, the recaptcha

why they need the PIN?

To confirm you are the owner of the account

But, the real question is, why on earth would they store customer's ATM PIN on their servers?

If they are doing a mandatory reset, or if you request to reset your password, and in that process, you are required to put in your PIN number for confirmation, it should be done through ATM only, because the encryption happens locally (between your card and the atm machine, encrypted)

But nope, from what the article says, you put in your ATM PIN number, and they verify through their server's side, means, they are storing the most crucial information about your card account, which they shouldn't

it could be

but knowing that CIMB is storing a piece of information that should be privileged for you and your eyes only, is scary

How is this abnormal, you ask? It scares even more that nobody else in our office managed to identify the problem. I’ve been in a lengthy discussion with the good guys at Nasi Lemak Tech and here’s what we have to say about it.

You see, your PIN (Personal Identification Number) is YOUR personal identifier which even the banks are NOT supposed to know.

    When you get your ATM card, you slot the card into the card reader and you set your temporary PIN which you are requested to change it again later at the ATM.
    When you registered e-banking for the first time, you have to pay a visit to the bank, insert your card, validate the PIN and then a temporary PIN is issued for your usage.
    When you do a VISA transaction using wave, you can just tap the card and get done with it, but if you want to use the PIN, you MUST insert the card into the terminal first, before entering the PIN.

As you can see, you can never eliminate the need to have your card physically before using your PIN. This is because, the PIN is stored in the card. When it is needed, the server sends an encrypted string to the machine, requesting the PIN to unlock the secure container. Once the PIN is entered, the validation happens on the machine level itself where it checks against the stored PIN on the card (of course, encrypted). When everything matches, the transaction details are carried with a verified payload back to the servers. This is how the process is supposed to work.

Well, the lowyat article explains things more clearly... But I'm still blur on the credit card and Paypal side.

1. CIMB customers' credit card information and CVV2 could have been compromised in the lost tape or some other way.

2. With this, couldn't the hackers just use this CC information to link up to Paypal and use this directly to steal money?

3. Whilst I understand the hacking attempts to go into CIMB Clicks portal, how does it help them to do no. 2? They could have done so directly, in the first place.

4. Any attempt to transfer will be negated by the need of TAC.

5. Unless the hacking into CIMB clicks is done directly without any information on the customer CC in the first place. After hacking, they obtain the CC details from CIMB Clicks and then proceed to link it to Paypal?

Password issue and Paypal are two separate issues, stacked on top of each other

hackers don't need to go to cimbclicks to link your card info with an unknown paypal account
