If you have ever peeked at your web server logs or run a vulnerability scanner, you have likely encountered a curious request for /vdesk/hangup.php3 . To the uninitiated, it looks like a remnant of the early 2000s web—a .php3 extension in a modern world. But for security researchers and sysadmins, it is the digital signature of the F5 BIG-IP ecosystem. What is it?
