An Iran-linked cyberattack group is threatening to release a batch of emails stolen from President Donald Trump’s closest associates. The same group distributed a similar trove of hacked emails to journalists prior to the 2024 election.

The group of hackers, which operates under the pseudonym “Robert,” claims it possesses about 100 gigabytes of emails involving Trump associates, including White House chief of staff Susie Wiles and Trump adviser Roger Stone, according to a Reuters report on the threat.
