A large-scale breach of F5 Networks was disclosed after the company discovered long‑term, persistent access by a highly capable nation‑state actor to certain product development and engineering systems. The intruders exfiltrated portions of BIG‑IP source code and undisclosed vulnerability/bug information. Customers are highly recommended to apply the latest patches to F5 appliances. The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. A partial list of potentially affected assets is outlined in this post.
