Overview
- Bluesky said a roughly 24‑hour distributed denial‑of‑service attack disrupted access across the US, UK and France and confirmed the incident in a post on August 17.
- The company said it upgraded its defenses and is monitoring activity but declined to disclose attack size, traffic origin, or how many users were affected.
- Independent researchers on the IFIN forum reported that the Islamic Cyber Resistance in Iraq‑313 Team claimed responsibility and that attackers appeared to use DiamWall‑based DDoS‑for‑hire infrastructure routed through a China‑based IP reseller.
- Experts warn that DDoS‑for‑hire services and reseller IP chains obscure where traffic actually originates because they route attacks through intermediaries and hijacked devices.
- The strike follows similar large outages in April and highlights operational and resilience challenges for smaller decentralized networks, with the potential for repeated targeting and continued service disruption for users.
