The FBI is investigating a potential hacking incident involving the iPhones of two senior officials from a presidential campaign, reportedly linked to a Chinese hacking group. Sources indicate that the phone of Trump's lead defense attorney was compromised, raising concerns about the security of mobile devices used by prominent Americans. The investigation follows evidence suggesting that Chinese hackers had backdoor access to the devices. This incident is part of a broader trend of Chinese cyber operations targeting U.S. officials, which has been described as more pervasive than previously understood. The FBI has been notified and is actively pursuing leads related to this incident.
