In the world of hacking, few names carry as much weight—and as much infamy—as Sabu. Once the most feared “rooter” for the hacktivist collective Anonymous, Sabu (Hector Xavier Monsegur) eventually became the central figure in one of the biggest federal takedowns in digital history. In this video, we go beyond the headlines and dive straight into the official court documents of US v. Monsegur. We break down the “Three Acts” of Sabu’s career: from the politically charged “Operation Payback” that hit Visa and Mastercard, to the surgical strikes of the Internet Feds, and finally, the chaotic 50-day spree of LulzSec.
