In January 2018 a group of hackers, now thought to be working for the North Korean state-sponsored group Lazarus, attempted to steal $110 million from the Mexican commercial bank Bancomext. That effort failed. But just a few months later, a smaller yet still elaborate series of attacks allowed hackers to siphon off 300 to 400 million pesos, or roughly $15 to $20 million from Mexican banks. Here’s how they did it.

At the RSA security conference in San Francisco last Friday, penetration tester and security advisor Josu Loza, who was an incident responder in the wake of the April attacks, presented findings on how hackers executed the heists both digitally and on the ground around Mexico. The hackers’ affiliation remains publicly unknown. Loza emphasizes that while the attacks likely required extensive expertise and planning over months, or even years, they were enabled by sloppy and insecure network architecture within the Mexican financial system, and security oversights in SPEI, Mexico’s domestic money transfer platform run by central bank Banco de México, also known as Banxico.
