    So the Secret Service just rolled up a massive SIM farm in NYC, and it looks like a nation-state operation. We're not talking about some small time fraud, but an infrastructure play with 100,000 SIM cards, apparently capable of taking down the city's cellular grid. This feels less like simple espionage and more like preparation for some kind of offensive cyber or information warfare campaign. The fact that it was discovered during an investigation into threats against officials makes you wonder what the primary mission really was.
    TL;DR
    ⚠️ A massive SIM farm with 100,000 cards was seized in New York City.
    🕵️ The operation is believed to be the work of a nation-state actor.
    💥 The setup was powerful enough to potentially disable cell towers and launch denial of service attacks.
    🤔 The ultimate goal is still unclear, but it points toward offensive capabilities, not just simple fraud.
