Stealing financial information is a lot different than stealing specific financial information. Anyone can dumpster dive, but the trick is knowing what dumpster contains the information on a mark.
I didn't consider dumpster diving when I hear about laptops of millions of customer data stolen and social exploits. Those social exploits are having bank employees put keyloggers indirectly on their own computers and being able to read any kind of information in the system.
Considering that he's doing it from Lagos, it might also mean that security is not very strong.
