It's not the kind of secret that would keep very well.

There are plenty of reasons for everyone (both the criminals and the
banks) to keep such a success very, very secret.

They might try to, but I'm sure they'd fail. If the criminals and the
banks conspired together such that only the banks saw any financial
loss, then they might get away with it (although it would be simpler for
the banks just to pay the criminals direct). Otherwise there will be
third parties seeing losses, and questions would be asked.
