Bluesky Confirms DDoS Attack Caused Day-Long Disruption

Bluesky, the social networking platform, reported a day-long disruption attributed to a distributed denial-of-service (DDoS) attack that inundated the site with junk traffic. The company confirmed the attack occurred over the preceding 24 hours in a statement released on Monday.

In response to the incident, Bluesky stated, “We have upgraded our defenses in response, and we continue to monitor the situation,” though further details regarding the attack were not disclosed.

A spokesperson for Bluesky did not immediately respond to inquiries from TechCrunch regarding the specifics of the attack.

DDoS attacks are characterized by overwhelming a website or server with excessive volumes of traffic, intending to overload resources and force the site offline. These attacks often utilize vast networks of hijacked internet-connected devices, which may include residential proxies or botnets, to redirect their unused bandwidth towards targeted web servers.

Security researchers discussing the incident in the IFIN public forum have indicated that attackers linked to Iran have claimed responsibility. Notably, Iran has escalated its cyber assaults on U.S. companies and critical infrastructure following the onset of the ongoing conflict led by the U.S. and Israel earlier this year.

This incident marks the latest in a series of significant DDoS attacks affecting Bluesky. Previously, in April, the platform experienced a similar series of outages caused by excessive web traffic; however, it remains unclear whether there is a connection between the two events.
