Bluesky, the decentralized microblogging social media platform, reported service outages last week due to a distributed denial-of-service (DDoS) attack aimed at its systems.
The DDoS attack appears to have started late on April 15 (Pacific Time) and continued into the next day. The company described it as a sophisticated attack that caused intermittent app outages.
“The attack is impacting our application, with users experiencing intermittent interruptions in service for their feeds, notifications, threads and search,” Bluesky said.
“We have not seen any evidence of unauthorized access to private user data,” it added.
The company did not say who was behind the attack. A hacker group called 313 Team took credit for taking down the social media service, but their claims have not been independently verified.
313 Team, also known as ‘Islamic Cyber Resistance in Iraq’, claims to be a pro-Iran hacktivist group. The hackers have been active during the ongoing conflict between the United States, Israel, and Iran.
While these types of groups may be capable of launching disruptive attacks — they are often a persona used by government agencies — they have been known to make exaggerated or false claims.
In the statement announcing the attack, 313 Team said the attack was expected to last for 3 hours, but based on Bluesky’s status updates the DDoS attack lasted for roughly 24 hours.
Bluesky said it managed to mitigate the attack and prevent extended service outages, despite the assault continuing.
