OpenAI confirms ChatGPT suffered DDoS attack

OpenAI has confirmed that its services have been affected by DDoS attacks since Tuesday 7 November 2023, after experiencing intermittent outages of its APIs and ChatGPT.

Services returned to normal on Thursday 9 November following the resolution of the security incident, which was initially attributed to exceptionally high demand for the service. However, a subsequent investigation confirmed the presence of a DDoS attack that disabled its services for several hours.

In a statement published via Telegram, the hacker group Anonymous Sudan claimed to be responsible for the attack over an allegedly biased stance taken by OpenAI, related to the ongoing military conflict in Israel. The organisation claimed to use the SkyNet botnet to breach the platform's security mechanisms. In June, Anonymous Sudan also claimed responsibility for DDoS attacks against Outlook, OneDrive and Microsoft Azure systems.
