Red Team Blues - Cory Doctorow - Bog

Money-laundering, cyber-knavery and shell-company chicanery: Marty Hench is an expert in them all. He's Silicon Valley's most accomplished forensic accountant and well versed in the devious ways of Fortune 500s, divorcing oligarchs, and international drug cartels alike (and there's more crossover than you might imagine).

In cyber-security, RED TEAM plays attack. BLUE TEAM plays defence.
Marty Hench's career in tech is almost as old as Silicon Valley. He's the most accomplished forensic accountant in town, an expert on the international money-laundering and shell-company chicanery used by Fortune 500s, divorcing oligarchs, and international drug cartels alike (there's more crossover than you might imagine).
Marty was born to play attack. If there's a way to get under the walls and bring the castle down, he's the one to do it. There's no better financial Red Teamer in the Valley.
Now he's on the trail of a stolen key, one that unlocks an illicit backdoor to billions in crypto. More than reputation and fortune is on the line - Marty's adversaries are implacable criminal sadists who will spill oceans of blood to get what they want.
Finding the stolen key is going to be the least of Marty's problems: now he has to save his skin. To do that, he'll have to play defence. And Marty hates playing the Blue Team.
