A digital forensic analysis found the encrypted message to be the source of the malware, making it "highly probable" the intrusion was triggered by the infected video.
Digital forensic experts started examining Bezos's phone following the publication last January by the National Enquirer of intimate details about his private life.
Bin Salman has repeatedly denied he was behind Khashoggi's murder.
The UN special rapporteurs, Agnes Callamard and David Kaye, said on Wednesday that they had information pointing to the "possible involvement" of Crown Prince Mohammed bin Salman in the alleged 2018 cyberattack.
Ms. Callamard, the special rapporteur for extra-judicial killings, and Mr. Kaye, special rapporteur for free expression, said the allegation of Saudi involvement "demands immediate investigation by US and other relevant authorities".

Israeli spyware firm NSO Group's U.S. lobbying campaign just got a lot more complicated after United Nations investigators today concluded that Saudi use of its Pegasus spyware was the "most likely explanation" for a 2018 hacking attack against Amazon CEO and Washington Post owner Jeff Bezos.
The Amazon chief declined to halt the investigation, instead publishing copies of emails from AMI.
The newspaper, while quoting "Saudi experts", which include dissidents, said that the alleged hack may be a result of Bezos' ownership of The Washington Post, which published articles written by slain journalist Jamal Khashoggi, which were critical of the Kingdom.
After Khashoggi's murder, the Washington Post aggressively reported on the circumstances surrounding it and the involvement of Bin Salman.
Last year, Gavin de Becker, a security specialist known for assisting the Central Intelligence Agency and Federal Bureau of Investigation, claimed that the Saudi government had hacked the phone of Jeff Bezos, the world's richest man. "The file, it appears, contained malware, which allowed Bezos' phone to be hacked, leading to leaks of photos created to embarrass him". The Intercept first reported in 2018 that Kushner used the app to communicate with the crown prince, and Kushner attorney Abbe Lowell told the House Oversight Committee that Kushner used the app for official government communications, including with foreign officials.
In March a year ago de Becker said he concluded that Saudi Arabian authorities hacked the Amazon chief's phone to access his personal data.
