It's not about nric...more of how personal data is so poorly protected and this is making things worse and enabling hackers who already have data containing nric..The NRIC has 7 digits and a checksum.
Unmasking the last 3 digit and checksum, and with the birth year known, we are left with
S/T 79XX123C
The logic for generating the checksum is not a secret. Just Google for it. Now with these information, how many permutations are there in the 3rd and 4th digit that will pass the checksum? Just need to reverse the logic.
And the 3rd and 4th digit is also tied to the person's birth sequence in that year so the later one is born in the year, the higher the number.
The sooner we stop thinking that our NRIC is secret, the better.
