Us officials say China-backed hackers behind F5 cybersecurity breach, Bloomberg reports

Chinese state-sponsored hackers accessed F5's BIG-IP source code and vulnerability data for over a year, targeting Fortune 500 companies and government agencies, F5 said.

  • On Wednesday, F5 Inc., Seattle-based US cybersecurity company, disclosed a significant cyberattack that gave threat actors long-term, persistent access to its BIG‑IP product development environment used by Fortune 500 companies and government agencies.
  • Sources told Bloomberg that Chinese state-sponsored hackers remained in F5 Inc.'s network for at least a year, and F5 said it first learned of the breach earlier this year.
  • F5 said the attackers exfiltrated files including some BIG‑IP source code and undisclosed BIG‑IP vulnerabilities, and breached the engineering knowledge management platform.
  • F5 Inc. released updates for BIG‑IP, F5OS, BIG‑IP Next for Kubernetes, BIG‑IQ and APM clients and said it has taken `extensive actions to contain the threat`.
  • Federal authorities called the threat `significant` and urged agencies to update F5 devices immediately, the UK's National Cyber Security Centre warned of credential theft risks, and F5 reported no evidence its CRM or financial systems were accessed.
