The FBI is investigating allegations that Iranian hackers breached the Trump campaign's internal communications, reportedly stealing sensitive documents. The intrusion, detected by Microsoft, involved a spear-phishing email sent from a compromised account linked to a former senior adviser. While Iran has denied involvement, the techniques used closely match those known to be employed by Iranian hackers. The hack has raised concerns about foreign interference in the 2024 U.S. presidential election, with experts warning of increasing cyber threats from Iran, Russia, and China. Trump’s campaign has accused Iran of attempting to influence the election, echoing previous cybersecurity warnings about foreign malign activities targeting U.S. elections. The Biden-Harris campaign was also briefed about similar threats, though they have not reported any breaches.
