Columbia University was hit by a suspected cyberattack Tuesday morning that knocked its systems offline for several hours, prompting the school to notify authorities, according to sources and reports.

“This morning, Columbia University IT systems experienced an outage affecting systems on our Morningside campus,” the embattled Ivy League school said in a statement to The Post.

“Our IT team has been working to restore services as quickly as possible, and we have notified law enforcement. At this time, no clinical operations at CUIMC have been impacted.”

Sources told The Post that a low-level access control breach brought down Columbia’s systems early Tuesday morning.

The suspected hack triggered bizarre images to display on screens across campus – though officials are unsure whether they’re linked to the broader outage.

At least one dorm TV on Columbia’s Morningside campus flashed an image of President Trump, according to a photo obtained by the Columbia Spectator.

The university newspaper also reported online posts from a group claiming responsibility for the outage – assertions that the Ivy League has since debunked.

Several student services, including the school email system and CourseWorks – a portal used by professors to share student assignments – were impacted by the outage, the Spectator reported.

The Columbia community was first alerted around 7:30 a.m. via email about “widespread system outages,” with efforts underway to restore services.

About three hours later, students and faculty were urged to stay logged into their accounts to maintain access to the university’s online services, the outlet reported.

The NYPD had no knowledge of a potential hack or outage on the Manhattan campus.

It remains unclear which law enforcement agency is investigating.

Americans nationwide have been warned to brace for a potential wave of cyberattacks from Iran following Trump’s historic bombing of three of the country’s nuclear facilities Saturday.
