X, the social media platform formerly known as Twitter, was hit by a large-scale cyberattack on Monday, causing widespread disruptions across the platform. Elon Musk, the platform’s owner, described the incident as a “massive cyberattack” and suggested that its scale and sophistication pointed to a well-funded entity, possibly a nation-state.

Reports of outages began surfacing a few hours ago, with Downdetector.com logging more than 40,000 complaints by early evening India Time. Users described an inability to load posts, persistent buffering, and error messages. The disruptions were particularly acute along the U.S. coasts, affecting a significant portion of the platform’s user base.

“This was not a typical attack,” Musk wrote in a post on X. “The magnitude suggests significant resources were involved.”

The attack comes at a time when Musk has been increasingly vocal about geopolitical issues, engaging in high-profile debates over topics ranging from the Russia-Ukraine war to tensions in the Middle East. His recent statements have drawn sharp reactions from various governments and political figures, raising questions about whether the cyberattack could be linked to adversarial forces seeking to retaliate.

The incident underscores the vulnerabilities of modern social media networks, which remain prime targets for cyber threats, from rogue actors to state-sponsored operatives.

X has yet to disclose further details about the origins of the attack or any potential perpetrators. The company has assured users that it is actively investigating the breach and working to reinforce security measures.
