    • Stuxnet is a worm that targets industrial control systems, particularly Siemens systems used in nuclear power plants.
    • Stuxnet was one of the first pieces of malware to be discovered in a series of nation-state cyberattacks.
    • Stuxnet caused the destruction of physical hardware such as uranium-enriching centrifuges.
    • Stuxnet's earliest infections occurred around June 2009.
    • Stuxnet is very technically advanced and unique.
    • Stuxnet exploited four Windows Zero-Day vulnerabilities.
    • Stuxnet used 100% reliable exploits that were 100% effective against vulnerable systems.
    • Stuxnet utilized a zero-day exploit in LNK (shortcut) files that allowed arbitrary dynamic link libraries (DLL) to be executed in the security context of the current user.
    • Stuxnet utilized a privilege escalation vulnerability in the task scheduler that affected Windows Vista allowing code to execute as Local System.
    • Stuxnet utilized a privilege escalation vulnerability in keyboard layout files that affected Windows XP allowing code to execute as Local System.
    • Stuxnet utilized a remote exploit that used the print spooler subsystem to send the Stuxnet virus to peers on the network.
    • Stuxnet's creators had a large stockpile of zero-day exploits.
    • Stuxnet included rootkits to conceal its existence and was digitally signed with legitimate certificates.
