The presidential campaign of former President Donald Trump claimed on Saturday that it had been hacked, with suggestions that Iranian actors were responsible for stealing and disseminating sensitive internal documents. While the campaign did not provide specific evidence linking Iran to the hack, the claim follows a report by Microsoft detailing attempts by foreign agents to interfere in the 2024 U.S. election.

According to the report, an Iranian military intelligence unit sent a spear-phishing email to a high-ranking official of a presidential campaign using a compromised email account of a former senior advisor. The Trump campaign spokesperson attributed the hack to “foreign sources hostile to the United States,” although the National Security Council has not yet responded to these claims.

The hack was first reported by Politico, which received emails from an anonymous account containing what appeared to be a research dossier on Republican vice presidential nominee JD Vance. The documents were dated February 23, prior to Vance’s selection as Trump’s running mate.

Steven Cheung, the campaign spokesperson, condemned the hack as an illegal interference in the electoral process and warned against the dissemination of the stolen documents by media outlets. He referenced the Microsoft report linking Iranian hackers to a high-ranking official on a U.S. presidential campaign in 2024.

Iran’s United Nations mission denied any plans to interfere in the U.S. election, while Microsoft’s analysis suggested that Iranian cyber-attacks have become a recurring feature of recent election cycles in the U.S.

The report detailed how an Iranian military intelligence unit sent a phishing email to an American presidential campaign in June 2024, highlighting the evolving tactics of foreign actors trying to disrupt the electoral process.

As the investigations continue, the cybersecurity measures of all presidential campaigns, including Vice President Kamala Harris’, are under scrutiny in the face of potential foreign interference.
