The popular social media site X, run by billionaire Elon Musk, is the victim of a “massive cyberattack” Monday.

“There was (still is) a massive cyberattack against X,” Elon Musk said in a post at 1:25 p.m. Eastern.

“We get attacked every day, but this was done with a lot of resources. Either a large, coordinated group and/or a country is involved. Tracing …”

Worldwide users of the site formerly known as Twitter, on Monday have been experiencing intermittent outages.

Reports confirmed posts were not loading for users in the United States, United Kingdom, France and India over various time frames.

A report from Newsweek said the hacking group called “Dark Storm Team” reportedly was claiming responsibility for the DD0S attack.

Dark Storm is known, according to the report, “for its sophisticated cyber warfare attacks and successful hacks of high-security systems.”

The report explained, “According to Orange Cyberdefense, the group was formed in 2023 and has a pro-Palestinian focus.”

It recently had promised cyberattacks on various sites involving NATO countries, Israel and nations that support Israel.

Cloudflare said the obvious signs of a DDoS attack, which involves simultaneously directly millions of queries to one website, are “when a website or service suddenly becomes slow or unavailable.”

The Independent described the outage as “major and global.”

The report said, “More than 40,000 users in the U.S. reported having issues at the peak, according to the monitoring website Down Detector. Elon Musk, who bought X in 2022, didn’t mention the outage on his own account. He posted earlier on Monday that X is ‘the top source for news on Earth.'”
