The bit flipped happened in the template I used when I made changes to it in October. It subsequently affected all invoices I sent since that date. Luckily all of these had already been paid by card, so no transactions were made to the incorrect number.

@marver - maybe we should revisit our plans to do bit-flip squatting on the IP addresses of mayor websites and see how we can apply this to financial systems?Show this thread

Wow, I've never seen a bit flip in my life. Was it in a file (what type) or in a database? On a disk or in transit?
-
The first 2 were "in memory" changes to JavaScript during fuzzing; a bit flipped and turned "document" to something like "dpcument". That JS was static and not part of fuzzed data so my fuzzer reported an unexpected error, which is how I found out.

I found out about this latest one because it was in a file. That file was generated from a template file, which also contained the flipped bit. So, it was either flipped on-disk in the template file or in memory when I last edited it and then saved to disk.

From what I understand bit-flips in cheap non-ECC memory are not that uncommon. Especially if you "hammer" the memory :). I guess the high temperatures from fuzzing at 100% 24/7 also does not help. (The later does not apply to my desktop OC).
