How many zero-day vulnerabilities did Stuxnet?
four zero-day vulnerabilities
According to Ryan Naraine of ZDNet, the Stuxnet worm—discovered in 2020—used four zero-day vulnerabilities.
What vulnerabilities does the Stuxnet virus exploit?
Indexed as CVE-2010-2568 by Microsoft, the exploit targets a code execution vulnerability that can be triggered by plugging a malware-laden USB stick into a computer that’s running an unpatched older version of Microsoft Windows, including Vista and XP.
What type of zero days did the Stuxnet malware contain?
Many security companies, including Symantec and Kaspersky have said that Stuxnet was the most sophisticated attack they had ever analyzed. Stuxnet uses four zero-day exploits, a Windows rootkit, the first known PLC rootkit, antivirus evasion techniques, peer-to-peer updates, and stolen certificates from trusted CAs.
What is the meaning of zero-day vulnerability?
A zero-day vulnerability is a vulnerability in a system or device that has been disclosed but is not yet patched. An exploit that attacks a zero-day vulnerability is called a zero-day exploit. Vulnerable systems are exposed until a patch is issued by the vendor.
What type of virus is Stuxnet?
Stuxnet is a computer worm that was originally aimed at Iran’s nuclear facilities and has since mutated and spread to other industrial and energy-producing facilities. The original Stuxnet malware attack targeted the programmable logic controllers (PLCs) used to automate machine processes.
How many computers were infected by Stuxnet?
Stuxnet reportedly ruined almost one-fifth of Iran’s nuclear centrifuges. Targeting industrial control systems, the worm infected over 200,000 computers and caused 1,000 machines to physically degrade.
What type of malware is Stuxnet?
Share: Stuxnet is a computer worm that was originally aimed at Iran’s nuclear facilities and has since mutated and spread to other industrial and energy-producing facilities. The original Stuxnet malware attack targeted the programmable logic controllers (PLCs) used to automate machine processes.
What is the effect of Stuxnet on cyber defense?
Stuxnet successfully targeted each of the three layers of a cyber-physical system. 1) It used the cyber layer to distribute the malware and identify its targets. 2) It used the control system layer (in this case, PLCs) to control physical processes. 3) Finally, it affected the physical layer, causing physical damage.
How does a zero day vulnerability differ from malware?
This is when software has a flaw known to the developer, but the developer does not yet have a patch ready to be released. A zero-day exploit is a software package coded to take advantage of the known zero-day vulnerability. In most cases, a zero-day exploit is packaged as malware.
