A hacker gained access to an online secure document-sharing file between attorneys involved in a civil lawsuit brought by a close friend of former Rep. Matt Gaetz, according to sources familiar with the matter.

Documents including unredacted depositions from key witnesses in the case are believed to have been taken, sources said.

Attorneys involved in the civil lawsuit, brought by a close friend of Gaetz, received an email Monday night last night informing them that “confidential” documents had been downloaded by an “unknown and unauthorized third party,” according to an email obtained by ABC.

Gaetz is not a party in the lawsuit, although he was subpoenaed for testimony given that some of the underlying allegations in the civil suit mention him.

On Sunday, a ShareFile link containing 24 exhibits from the civil case was accessed by someone using the name “Altam Beezley.” Those involved in the case believe the name is a pseudonym, and there is an ongoing investigation into the hack.
