What Happened?
Article content
On October 15, 2025, F5 revealed that it had learned in early August that a “highly sophisticated nation-state threat actor had gained unauthorized access to certain F5 systems.” The Company added, “during the course of its investigation, F5 determined that the threat actor maintained long-term, persistent access to certain F5 systems, including the BIG-IP product development environment and engineering knowledge management platform,” and that “through this access, certain files were exfiltrated, some of which contained certain portions of the Company’s BIG-IP source code and information about undisclosed vulnerabilities that it was working on in BIG-IP.” On this news, the price of F5 shares declined by $35.40 per share, or approximately 10.70%, from $330.75 per share on October 15, 2025 to close at $295.35 on October 16, 2025.
