The Secret Service started out as an anti-counterfeiting service, expanded into VIP protection, general national financial system security, and for a while general cybercrime, though the latter (outside of where it touched on the other Secret Sevice functions) fell away.
“We also protect the integrity of our currency and investigate crimes against the U.S. financial system committed by criminals around the world and in cyberspace.” https://www.secretservice.gov/about/overview
I’m also surprised the secret service was involved. I wonder if they suspected foreign involvement or considered it a matter of national security because it was an attack on banking infrastructure?
