We had a 5.15 cent charge for "TikTok" on a business card we never used. We have very good password hygene, and we have Ubikey authentication for all our business accounts. The bank initially told us to file a police report (!) for identity theft.

I knew it wasn't identity theft. We got a notice a week later that the charge had been reversed; we never bothered with a police report, we just cancelled the card. It had been flagged as suspicious by the bank when it was initially processed, but I'm not sure what was wrong. Perhaps one factor, like expiration date or zip code wasn't right.

I have a feeling it was stolen with some scheme like this where people just guess numbers by some algorithm.
