F5 Cyber Breach: Chinese Hackers Allegedly Swipe Source Code—But No Need to Panic (Yet)
State-sponsored hackers recently infiltrated F5, stealing sensitive information, including BIG-IP source code. Despite the breach, F5 claims their software supply chain remains unmodified. While some customer data was accessed, no critical vulnerabilities were exploited. In a twist worthy of a spy novel, the attack profile hints at Chinese involvement.

Hot Take:
Looks like F5’s systems were as inviting to hackers as a buffet is to a starving college student. Despite the breach, F5 insists it’s not a big deal. But then again, who wouldn’t downplay a break-in when the burglars left the silverware and only took the blueprints? Meanwhile, somewhere in China, a group of hackers are exchanging high-fives and pondering over the borrowed BIG-IP source code like a group of detectives solving a mystery.
Key Points:
- F5’s systems, including its BIG-IP platform, were accessed by state-sponsored hackers.
- Hackers extracted files, including BIG-IP source code and info on undisclosed vulnerabilities.
- No evidence of critical vulnerabilities being exploited or modifications to F5’s software.
- F5 suspects Chinese state-sponsored hackers are behind the attack.
- Attack detected on August 9, but disclosure was delayed with US Justice Department’s permission.
