The 31-second video appears to focus on the outside of the American station and within seconds, 'six large' glowing orbs crept past the camera.
According to the Daily Mail the sighting was originally spotted by Youtube user Streetcap1, who then shared the clip online.
The video was shared with alien conspiracy website SecureTeam and Tyler from group told the website that he believed the items would be "fairly large".
"Much larger than NASA's typical excuse of ice particles, we must be looking at icebergs."
Tyler explained that suspiciously NASA cut the live feed and replaced it with feed from camera showing the inside of a briefing room.
Last month John Craddick, from Wolverhampton in the UK, claimed he spotted another UFO on the ISS live feed.
He told the Mirror: "I've been watching it [the live feed] for years but never seen any UFOs on it before.
"I was showing a friend how it worked at around 11.30pm when the feed cut out, and 35 seconds after it came back on, this object appeared.
"At first it was really small and then it grew bigger, lasting for about 25 seconds," he said.
Mr Craddick claims that it must be alien because "nothing human can fly that high"

The second looks like the Millennium Falcon going into hyper drive or maybe it is a black hole that instantly, upon forming, falls back in on itself.
*sigh* They can send us to the bottom of the Marianas trench, supposedly to the moon, spy on our every uttered word, give us 'smart TV's and I phones but cannot give us a clear picture of a space ship. Therefore, SOTT needs to rely on Secure team 10 to tell us how huge they are. Perhaps they are heading to that 3.4m wide doorway on Mercury Tyler:
Massive 3.4 mile 'doorway' spotted on Mercury allowing 'UFOs' to travel in and out?
A huge door-like object has been spotted on the planet Mercury's surface and UFO hunters are convinced it is a portal for alien spacecraft to travel in and out. The bizarre image - captured on the...We get hazy pics of the moon, mars, ect., conveniently distorting any potential return on our tax dollars. The deep state is a parasite feeding off our livelihood, and any dividends we would benefit from space exploration. I would not be surprised to find out they have a parallel space program that makes the public program look like an outdated joke.
