An analysis conducted by forensic investigators concluded that it was “highly probable” that inside the encrypted message from Saudi Crown Prince Mohammed bin Salman was a malicious file that proceeded to siphon large amounts of data from Bezos's phone, according to the report from The Guardian published Tuesday.

Sources did not detail any specifics about the information taken with The Guardian.

The message was reportedly sent to Bezos after he and the crown prince had a cordial conversation on the messaging app on May 1, 2018.

Nine months after the supposed hack, the National Enquirer published intimate details about Bezos's private life, including an extramarital affair.

The tabloid has claimed it received the information from the estranged brother of Bezos's girlfriend, but the billionaire's private team of investigators has "high confidence" that the Saudis hacked the information from Bezos's phone, The Guardian reported.

Saudi Arabia and American Media Inc. — the then-owner of the National Enquirer — have both denied that the kingdom was involved in the publishing of the story.

The Hill reached out to Amazon for comment.

One of Bezos' lawyers told the Guardian: “I have no comment on this except to say that Mr. Bezos is cooperating with investigations.”

Allegations of a Saudi tie to the hack of Bezos' phone will also raise more questions about the actions of the crown prince ahead of the murder of Washington Post journalist Jamal Khashoggi in October 2018. Bezos is the owner of the Post.

Agnès Callamard, the UN special rapporteur who investigates extrajudicial killings, investigated Khashoggi's murder and found “credible evidence” that the crown prince other senior Saudi officials were responsible for the killing.
