I guessed 3 digits of a colleague's PIN based on his religion - he was a bit taken-aback. He didn't realise that loads of Muslims would pick the same number.
Nice one edlong! That read just like an edition of R4's More or Less 🙂

I'm slightly dubious about his data, because that's what I'd probably use as a test password or where I wasn't at all bothered - and I suspect such sets of passwords may well have made it into his database.
No they weren't. They were on tv raiding the Iranian embassy (in 1980) and there was a siege at the Libyan embassy in 1984, but it didn't end with an SAS raid. And there's only one "i" in "Libyan".
Ah my mistake.
No, then yes (maybe) but no, but then checked, and actually maybe yes after all:10,000 possible combinations, going from 0000 to 9999 inclusive.
Yes it's 10,000 I've no idea if they block any though.

570?
today in 1984, Andy Kaufman (REM's "Man on the Moon") pegged out
or did he?
How is it possible to of not of heard of 1984?
If you want to keep a secret, you must also hide it from yourself.
which leads to another point - close your eyes and make random button presses so not even you know your PIN.
I got a Spectrum in 1984 and learned how to program. Years later I did the coding for how the banks bill each other for when customers from one bank use another bank's ATM - feeds into Oracle EBS, far more complicated than you might imagine....

On that note, here's how to safely write your PIN number on your card so you never forget it:

I "wrote down" my PINs when I first had a bank account, using a similar but slightly different method. Missed the trick of writing the ciphertext on the card though.
