Social networking site Bluesky announced that a recent day-long service disruption was caused by a distributed denial-of-service (DDoS) attack. The attack flooded the site with junk traffic, leading to an outage over a 24-hour period.
Bluesky stated it has upgraded its defenses in response to the attack and continues to monitor the situation. No further details about the incident or the specific measures taken were disclosed by the company.
Security researchers in the IFIN public forum reported that Iran-backed attackers claimed responsibility for the DDoS attack. This aligns with an increase in attacks by Iran on U.S. businesses and critical infrastructure since the start of the U.S. and Israel-led war earlier this year.
This is not the first large-scale DDoS attack to affect Bluesky in recent months. In April, the platform experienced a prolonged series of outages due to a similar flood of web traffic. It remains unclear if the recent attack is linked to the previous incidents.
