I trust 404 media more than most sources, but I can’t help but reflexively read every story prominently showcasing the FBI’s supposed surveillance gaps as attempted watering hole attacks. The NSA almost certainly has hardware backdoors in Apple silicon, as disclosed a couple of years ago by the excellent researchers at Kaspersky. That being the case, Lockdown Mode is not even in play.
The NSA is not going to tip its hand about any backdoors it had built into the hardware for something as small as this.
