Bluesky Hit by Prolonged DDoS Attack Amid Hacktivist Claims
Bluesky, the decentralized social media platform, experienced service disruptions last week following a sophisticated distributed denial-of-service (DDoS) attack. The assault began late on April 15 (Pacific Time) and persisted for roughly 24 hours, causing intermittent outages affecting user feeds, notifications, threads, and search functionality.
The company confirmed that while the attack disrupted operations, there was no evidence of unauthorized access to private user data. Bluesky stated it successfully mitigated the attack, preventing prolonged downtime despite its duration.
A hacktivist group calling itself 313 Team (also known as Islamic Cyber Resistance in Iraq) claimed responsibility for the attack, asserting it would last only three hours a claim that proved inaccurate. The group, which has been active amid geopolitical tensions involving the U.S., Israel, and Iran, has a history of making unverified or exaggerated statements. Security experts note that such groups may sometimes serve as fronts for state-affiliated actors.
The incident follows a recent surge in high-profile DDoS attacks, including law enforcement takedowns of DDoS-for-hire domains and record-breaking botnet-driven assaults on infrastructure targets.
