A hacker group DieNet has claimed responsibility for the global shutdown social media platform X, formerly Twitter, experienced on Saturday, according to SITE Intelligence Group.

DieNet, per SITE Intelligence, had called the attack a “test” of its so-called Distributed Denial of Service (DDoS) capabilities — flooding the system with online traffic to make it inaccessible to legitimate users.

The new hacktivist group has claimed responsibility for over 60 cyberattacks, using DDoS methods. It has targeted important systems like U.S.

public transport, Iraqi government websites, and services in transportation, energy, healthcare, and online shopping.

DieNet first introduced itself on March 7, 2025, through a Telegram channel that has since been banned.
After the X outage, billionaire owner Elon Musk said he would be more involved in his businesses to forestall recurrence.

The world’s richest person has an extraordinarily full plate as owner/CEO of X, xAI (developer of the AI-powered chatbot Grok), electric-car maker Tesla and rocket builder SpaceX — not to mention his recent polarizing efforts to help Trump slash the size of the US federal government.

“Back to spending 24/7 at work and sleeping in conference/server/factory rooms,” Musk posted on X.

“I must be super focused on X/xAI and Tesla (plus Starship launch next week), as we have critical technologies rolling out.”

The South African-born billionaire has for weeks been signaling that he would reduce his political role to refocus on his businesses.

Early this month, Musk acknowledged that his ambitious effort to slash US federal spending did not fully reach its goals, despite tens of thousands of job cuts and drastic budget reductions.

Before the Saturday attack on X, DieNet had attacked American institutions such as the Los Angeles Metropolitan Transportation Authority, the Port of Los Angeles, the Chicago Transit Authority, and the North American Electric Reliability Corporation.
