How was the Stuxnet virus stopped?
On June 24, local time, the replication routines in Stuxnet turned themselves off, effectively halting the spread of the sophisticated cyber weapon. According to researchers who have analyzed Stuxnet code, it was a feature, not a bug.
What type of threat 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.
Is Stuxnet legal?
A cyberattack that sabotaged Iran’s uranium enrichment program was an “act of force” and was likely illegal, according to research commissioned by NATO’s cyber warfare center.
Was Stuxnet successful?
The Stuxnet virus is often held up as a fantastic success. As part of a larger U.S.-Israeli effort to sabotage Iran’s nuclear facilities, Stuxnet is probably the most sophisticated, complex, and powerful cyber weapon ever used. According to Wired magazine, Stuxnet “was unlike any other virus or worm that came before.
Did Stuxnet succeed?
If its goal was to quickly destroy all the centrifuges in the FEP [Fuel Enrichment Plant], Stuxnet failed. But if the goal was to destroy a more limited number of centrifuges and set back Iran’s progress in operating the FEP, while making detection difficult, it may have succeeded, at least temporarily.
What zero-day exploits did Stuxnet use?
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. There is evidence that Stuxnet kept evolving since its initial deployment.
Is Stuxnet ethical?
The paper finds that even a cyber weapon like Stuxnet, which was ostensibly employed for a “good” purpose, presents major ethical concerns since it represented an attack on a sovereign state and led to an escalation of cyber capabilities among countries.
How many computers did Stuxnet infect?
200,000 computers
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.

How many zero days did Stuxnet use?
four zero-day
According to Ryan Naraine of ZDNet, the Stuxnet worm—discovered in 2020—used four zero-day vulnerabilities. The Stuxnet worm is famous for damaging Iran’s nuclear infrastructure. Another famous example would be the Sony Pictures hack in 2014.
How did Iran respond to Stuxnet?
Communications minister says Iranian scientists have created a firewall to block computer viruses from harming infrastructure, like bug that damaged nuclear centrifuges. Iran has developed software to protect its cyber space against attacks like the Stuxnet virus, an Iranian government official said Thursday.
Is Stuxnet still a threat?
The threat of Stuxnet is still alive, thanks to the discovery of new zero-day vulnerabilities connected to an old Microsoft Windows flaw. The Stuxnet used the print spooler flaw, along with other zero-days, to spread through Iran’s nuclear facilities and physically damage uranium enrichment centrifuges.
Why should we worry about Stuxnet?
While ordinary computer users have little reason to worry about these Stuxnet-based malware attacks, they are clearly a major threat to a range of critical industries, including power production, electrical grids, and defense.
How can we protect industrial networks against Stuxnet?
Two important practices that might have helped protect against Stuxnet are virus scanning (or banning) of all USB sticks and other portable media, and endpoint security software to intercept malware before it can travel over the network. Other practices for protecting industrial networks against attacks include the following:
What is the Stuxnet virus?
Stuxnet reportedly destroyed numerous centrifuges in Iran’s Natanz uranium enrichment facility by causing them to burn themselves out. Over time, other groups modified the virus to target facilities including water treatment plants, power plants, and gas lines.
What is the replay attack in Stuxnet?
The replay attack was used by Stuxnet to hide its manipulation of centrifuge behavior. Their method injects a noise signal into the control law u k = L x ˆ k + Δ u k where Δ u k is the noise signal and x ˆ is the state estimate. They compute a residue function where z is the state estimate.
