The 'Dalmellington Bug' was particularly interesting: - While transferring £8000 from the main branch to a sub-branch, the system screen froze, the user pressed enter three more times, and each time they user pressed enter the system repeated the £8000 transfer, ending up with £32000 transferred, while the screen remained frozen, hiding what had occurred from the user. - The investigation showed that there were 112 potential occurrences of this bug over 5 years before it was fixed.
Some lightly technical articles that I found interesting: - https://www.theguardian.com/uk-news/2024/jan/09/how-the-post... - https://clarotesting.wordpress.com/2020/05/27/the-post-offic... (plus two following parts)

I'm surprised fraud[1] hasn't been raised more in the Horizon IT scandal, given that some of the bugs involved duplicating transactions, and some of these bugs had been uncovered during testing.
i.e. The Post Office/Fujitsu was claiming money from sub-postmasters based on transaction records that they already had good cause to suspect were potentially bogus.
[1] Edit: I mean fraud perpetrated by the Post Office/Fujitsu, rather than fraud perpetrated by the sub-postmasters.
