    Study Notes

    Stuxnet

    • Stuxnet is a Windows worm that targeted Siemens industrial control systems, specifically those used in nuclear power plants.
    • It was the first malware to be discovered in a series of nation-state sponsored cyber-attacks.
    • It caused physical damage to uranium-enriching centrifuges at the Natanz plant in Iran.

    Stuxnet Specifications

    • The virus was large, approximately 500kb (half a megabyte), and had different attack stages.
    • It was engineered to be reliable and stealthy.
    • The attack was a combination of four Windows Zero-Day exploits:
      • A vulnerability in the processing of LNK (shortcut) files
      • A privilege escalation vulnerability in the task scheduler (Windows Vista only).
      • A privilege escalation vulnerability in keyboard layout files (Windows XP only)
      • A remote exploit that used the print spooler subsystem.

    Stuxnet Operational Facts

    • The virus's authors had a significant stockpile of Zero-Day exploits to choose from for the attack.
    • Stuxnet used rootkits and legitimate certificates to mask its presence.
    • The device drivers used were signed by stolen certificates from JMicron and Realtek, located in Taiwan.
    • Stuxnet originally reported to command and control servers in Malaysia and Denmark.
    • These servers allowed the virus to receive updates and instructions, and send data back to its authors.
    • The malware was designed to target specific Siemens SCADA (Supervisory Control and Data Acquisition) systems.

    Global Points of Interest

    • The malware authors were believed to be located in the United States and Israel.
    • Stolen certificates came from Taiwan.
    • Command and control servers were based in Denmark and Malaysia.
    • The virus targeted the Natanz plant in Iran.
    • The attack was meant to cause physical damage to the uranium-enriching centrifuges at the plant.

    Stuxnet’s Impact:

    • First known instance of nation-state sponsored cyber-attacks inflicting real-world damage.
    • Demonstrated the potential for cyberattacks to disrupt critical infrastructure and cause physical harm.
    • Showcased the growing sophistication of cyberwarfare techniques.

    Nation-State Cyber Attacks

    • Stuxnet, Duqo, and Flame are three prominent cyberattacks attributed to nation-states targeting other nations.

    Stuxnet

    • A Win32 worm targeting industrial control systems, particularly Siemens systems used in nuclear power plants.
    • It was the first malware discovered in a suspected series of nation-state-sponsored cyberattacks.
    • It had a tangible impact, causing the destruction of physical hardware, specifically uranium-enriching centrifuges.
    • Discovered around June 2010, but evidence of infections dates back to at least June 2009.
    • Stuxnet is technically advanced and unique, with 500kb in size, various attack methods, and sophisticated design.

    Stuxnet Specifics

    • Utilizes four Windows Zero-Day vulnerabilities.
    • Exploits did not rely on memory corruption vulnerabilities, making them reliable and effective against vulnerable systems.
    • The creator of Stuxnet did not need to worry about target machines crashing or freezing, resulting in stealthy and reliable attacks.

    Stuxnet’s Four Exploited Windows Vulnerabilities

    • Zero-Day Exploit 1: A vulnerability in LNK (shortcut) file processing allowing execution of an arbitrary dynamic link library (DLL). This DLL executes in the user's security context and is loaded from an infected USB.
    • Zero-Day Exploit 2: A privilege escalation vulnerability in the task scheduler affecting Windows Vista. This vulnerability allows code execution as Local System.
    • Zero-Day Exploit 3: A privilege escalation vulnerability in keyboard layout files affecting Windows XP. This vulnerability allows code execution as Local System.
    • Zero-Day Exploit 4: A remote exploit using the Print Spooler subsystem to send the Stuxnet virus to peers on the network.

    Factual Observations about Stuxnet

    • Authors of Stuxnet had access to numerous Zero-Day exploits.
    • Stuxnet employed rootkits to conceal its presence.
    •  Rootkits were digitally signed using legitimate certificates stolen from JMicron and Realtek, both companies located in the Hsinchu Science Park, Taiwan.
    • Stuxnet reported to two command and control servers in Malaysia and Denmark.
    • These servers facilitated data transfer to the authors and received updates and instructions.

    Stuxnet Operational Facts

    • Malware authors were believed to be based in the United States and Israel.
    • The Natanz plant in Iran was targeted.
    • Command and control servers were located in Denmark and Malaysia.
    • Stolen certificates originated from Taiwan.

    Stuxnet Operational Facts

    • Stuxnet targeted specific Siemens SCADA (Supervisory Control and Data Acquisition) computer systems that control and monitor industrial equipment such as power management and utility systems.

    Stuxnet

    • A win32 worm designed to target industrial control systems, particularly Siemens systems used in nuclear power plants.
    • First malware identified as nation-state sponsored cyberattack with a tangible impact - physical destruction of uranium-enriching centrifuges.
    • Discovered around June 2010, but evidence of infections dates back to June 2009.
    • Technically advanced and unique, with a large size of 500kb (half megabyte) and multiple attack vectors.
    • Utilized four Windows Zero-Day vulnerabilities for exploitation.
    • Exploits were 100% reliable and effective against vulnerable systems, ensuring stealthy and reliable attacks.
    • The malware creators had a vast selection of exploits; chosen based on specific requirements.
    • Included rootkits for concealment, digitally signed using legitimate certificates.
    • Device drivers were signed using stolen certificates from JMicron and Realtek, both located in Taiwan.
    • Originally reported to two command and control servers in Malaysia and Denmark.
    • Servers enabled the virus to send data to authors and receive updates and instructions.
    • Key locations of interest: United States and Israel (malware authors), Nantaz plant in Iran, command and control servers in Denmark and Malaysia, and stolen certificates from Taiwan.
    • Specifically targeted Siemens SCADA systems for controlling and monitoring industrial equipment such as power management and utility systems.
