Trump campaign’s suspected Iranian hack may still be happening

A suspected Iranian hack of Donald Trump's presidential campaign has continued within the last 10 days and may still be happening, according to a journalist who received illegally obtained documents from the Republican nominee's election effort.

Judd Legum, the publisher of the progressive newsletter Popular Information, revealed that he was sent a letter that Trump's lawyer had written to the New York Times on 15 September from a source called "Robert", as well as dossiers on three potential running mates, including JD Vance, the current GOP vice-presidential nominee.

The letter was verified to be authentic. "Robert" appeared to be the same source who had leaked other Trump materials to Politico, the New York Times and the Washington Post in August. The FBI has said it is investigating that leak as a suspected Iranian hack. The source known as "Robert" has been linked by a Microsoft threat analysis to a group within the theocratic regime's Islamic Revolutionary Guard Corps (IRGC), which sent out phishing emails to presidential campaigns.

US intelligence agencies revealed last week that Iranian hackers passed sensitive information stolen from Trump's campaign to Joe Biden's now-defunct presidential campaign in June and July. Legum's disclosure suggests that the breach may have been more extensive than previously known and could still be under way despite the efforts of US security agencies.

Legum said that he received a message from "Robert" on 18 September containing the cover page of a dossier on Vance. "Robert refused to identify himself," Legum wrote, except to suggest it was the same "Robert" from the previous leaks.

Legum - whose own communications were made public after the 2016 Russian hack of Hillary Clinton's then campaign chair John Podesta - described then receiving a 271-page file on Vance, along with thick dossiers on Doug Burgum, the South Dakota governor, and Marco Rubio, the Florida senator, both of whom were considered by Trump as possible running mates. All documents were marked "Privileged & Confidential".

He said he was also sent a dozen emails purporting to be from senior Trump advisers Susie Wiles and Dan Scavino and pollster John McLaughlin, dated from October 2023 until last August.
