Concealment
An octopus on the sea floor is invisible until it moves. Irregularities inside enterprise records behave the same way: they are shaped to resemble ordinary activity, and they only reveal themselves in motion, across systems, over time.
How it hides
The transaction looks like thousands of legitimate ones around it, because it was built to.
Individually the amount is unremarkable. Only the repetition carries weight, and repetition is invisible per record.
A record exists that permits it. Whether the conditions of that permission were ever met is a separate question.
No single system holds enough of the story for any one team to see a problem in it.

What makes it move
A record only has to be consistent with the system that holds it. It does not have to be consistent with the contract that governs it, the operational log that should support it, or the payment that followed it. We reconcile those against each other, and the combinations that cannot all be true are what we investigate.
Illustrative examples only. Methods, thresholds and detection logic are proprietary and are not published.
After the reveal
Once something surfaces, analysts test the alternative explanations first. What survives that is quantified deterministically and traced back to preserved original evidence, so the finding holds up in front of a board, a regulator, or a counterparty.
