On Tuesday, a message was posted on a channel on the encrypted messaging app Telegram.
The user referred to Barron as the 'son of the mule of America' and shared a Google Maps image of where he goes to school in Washington DC.
According to AFP, the internet user who posted the threat against him wrote it under the username 'Dak Al-Munafiqeen' which is Arabic for 'striking the hypocrites'.
MEMRI said the post was designed 'to widely disseminate the call for assassination'.
'Several pro-ISIS Telegram channels have shared and forwarded the post,' they said.
The White House has not commented on the threat.
