🔒 On Oct. 15, 2025, F5 disclosed a nation-state compromise that exfiltrated source code and undisclosed vulnerability information from the BIG-IP product development and engineering knowledge platforms. F5 reports no evidence of modification to its software supply chain or access to CRM, financial, support case management, iHealth, NGINX or distributed cloud products. Unit 42 warns the theft could accelerate exploit development and recommends immediate patching, hardening, and targeted threat hunting for anomalous admin activity and configuration changes.

🔒 F5 Networks acknowledged that a highly sophisticated threat actor exfiltrated portions of BIG-IP source code, information about undisclosed vulnerabilities, and configuration data for a small percentage of customers. The company says there is no evidence of modification to its build pipelines or active exploitation of undisclosed critical vulnerabilities. F5 has released security updates for BIG-IP, F5OS, BIG-IP Next for Kubernetes, BIG‑IQ, and APM clients and urges customers to apply them immediately. CISA has directed federal agencies to assess internet-exposed BIG-IP devices, and F5 will provide eligible customers a free subscription to CrowdStrike Falcon EDR.

🔒 F5 has released security updates for BIG-IP products to address vulnerabilities whose details were stolen during a state-linked breach detected on August 9, 2025. The vendor patched 44 issues across BIG-IP, F5OS, BIG-IP Next for Kubernetes, BIG-IQ, and APM clients and says it has not seen evidence the flaws were exploited or publicly disclosed. Customers are urged to apply updates immediately and follow F5's guidance to increase logging and monitoring.

🔒 F5 disclosed that unidentified threat actors accessed its systems and exfiltrated files including portions of BIG-IP source code and documentation on undisclosed product vulnerabilities. The company attributed the intrusion to a highly sophisticated nation-state threat actor, reported detection on August 9, 2025, and said it has contained the activity. F5 engaged Google Mandiant and CrowdStrike, rotated credentials, strengthened controls, and advised customers to apply updates to BIG-IP, F5OS, BIG-IQ, and APM clients.

🔒 F5 disclosed that nation-state attackers breached its systems and exfiltrated portions of BIG-IP source code and information about undisclosed vulnerabilities after gaining persistent access to product development and engineering knowledge platforms. The company says it first detected the intrusion on August 9, 2025, and has found no evidence the stolen data has been exploited or publicly disclosed. F5 reports that its software supply chain was not compromised and no suspicious code modifications were observed, while it continues identifying customers whose configuration or implementation details may have been taken.

🛡️ CISA has issued Emergency Directive 26-01 requiring Federal Civilian Executive Branch agencies to install vendor-provided updates for at-risk F5 devices and software — including F5OS, BIG-IP TMOS, BIG-IQ, and BNK/CNF — by October 22, 2025. The action responds to disclosure that a nation-state actor maintained persistent access to F5 development environments and exfiltrated files containing embedded credentials and API keys. CISA will assess and support agency adherence and urges all entities using these products to apply mitigations immediately.

⚠ CISA issued Emergency Directive ED 26-01 directing Federal Civilian Executive Branch agencies to inventory and secure F5 BIG-IP hardware and software, assess public internet exposure of management interfaces, and apply vendor patches. Agencies must update specified F5 products by Oct. 22, 2025 (other devices by Oct. 31) and submit inventories to CISA by Oct. 29, 2025. The directive responds to a nation-state actor compromise that exfiltrated BIG-IP source code and vulnerability data.

🔒 A Chinese state-sponsored group tracked as RedNovember carried out a global espionage campaign from June 2024 to July 2025, compromising defense contractors, government agencies, and major corporations by exploiting internet-facing network appliances. The attackers rapidly weaponized disclosed flaws in devices from SonicWall, Ivanti, Cisco, F5, Sophos, and Fortinet, often within 72 hours of public exploit code. They deployed Go-based tools including Pantegana, Cobalt Strike, and SparkRAT, and relied on open-source tooling and legitimate services to obfuscate attribution and maintain persistent access.
