Indeed, the Secret Service raided the home of the guy who passed the bills and turned him into an informant. From there, they set up wiretaps that eventually led to printing plants in Israel. The Secret Service then watched as the gang moved their operations to New Jersey earlier this year. According to Bloomberg, agents surveilling the New Jersey location actually saw a tractor delivering a printing press.
Details on how the $100 bills were faked is scant, as you might expect, though you can bet it's a whole lot more sophisticated than cleaning product and an inkjet printer. The gang even came close to replicating the 3D security ribbon on the redesigned $100 bill. But eventually, even best counterfeiters seem destined to get caught. Unless there's someone even better out there that we don't even know about yet. [Bloomberg via Quartz]
