What did Stuxnet attack?
Stuxnet infiltrated Windows systems by exploiting various zero-day vulnerabilities such as remote code execution. It employed enabled printer sharing or LNK/PIF vulnerability executing the file when it is viewed in Windows Explorer. This malware accesses both user and kernel levels.
What is a Duqu attack?
Duqu is a remote access Trojan (RAT) that steals data from computers it infects. Duqu has been targeted at industrial equipment manufacturers, illegally collecting information about the manufacturer’s systems and other proprietary data.
What vulnerabilities does the Stuxnet virus exploit?
Zero-day attacks exploit zero-day vulnerabilities. According to Ryan Naraine of ZDNet, the Stuxnet worm—discovered in 2010—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.
Who did Stuxnet affect?
Iran
Stuxnet’s primary victim was Iran–around 60% of the computers it infected were located in the country. Indonesia had 18% and India 8% of Stuxnet infections, and other nations were affected in the low single-digit percents.
Which of the following is a Stuxnet?
Stuxnet is a computer worm (Option 3). The Stuxnet worm was developed under a confidential program called “Operational Olympic Games”.
When did Stuxnet attack happen?
June 2010
Recognition of such threats exploded in June 2010 with the discovery of Stuxnet, a 500-kilobyte computer worm that infected the software of at least 14 industrial sites in Iran, including a uranium-enrichment plant.
What kind of a malware is Duqu?
remote access Trojan
Analysis of the known Duqu variants identifies this malware as a remote access Trojan (RAT). As with other malware of this type, Duqu infects a vulnerable system and inserts itself into memory, giving it the look of a trusted running process.
How was Duqu used?
Similarly to Stuxnet, Duqu was highly targeted (having been discovered on less than 50 systems worldwide), used zero-day Windows kernel vulnerabilities to install itself, and used stolen digital keys to sign its components. Unlike Stuxnet, however, Duqu was not designed to disrupt industrial SCADA systems.
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 devices did Stuxnet infect?
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.
Is Trojan a Stuxnet?
That said, the mainstream news media keeps refering to Stuxnet as a worm. But Stuxnet is actually a Trojan, not a worm. While the words Trojan, worm, and virus are often used interchangeably, they are not exactly the same.
What is the Stuxnet computer virus?
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 torpig virus?
Torpig, also known as Anserin or Sinowal is a type of botnet spread through systems compromised by the Mebroot rootkit by a variety of trojan horses for the purpose of collecting sensitive personal and corporate data such as bank account and credit card information.
What is the Duqu worm?
Duqu is a highly advanced computer worm—first discovered on September 1, 2011, by CrySyS Lab of the Budapest University of Technology and Economics in Hungary—believed to have been created by the same individuals that created the Stuxnet worm that caused Iranian nuclear turbines to malfunction in 2010.
What type of malware is code Red virus?
worm
Code Red is a worm, which is a computer attack that propagates through networks without user intervention. This particular worm makes use of a vulnerability in Microsoft’s Internet Information Services (IIS) Web server software—specifically, a buffer overflow.
Is Stuxnet a rootkit?
The Stuxnet worm is a rootkit exploit that targets supervisory control and data acquisition (SCADA) systems. SCADA systems are used widely for industrial control systems, such as power, water and sewage plants, as well as in telecommunications and oil and gas refining.
Who created Stuxnet virus?
Who created Stuxnet? It’s now widely accepted that Stuxnet was created by the intelligence agencies of the United States and Israel. The classified program to develop the worm was given the code name “Operation Olympic Games”; it was begun under President George W. Bush and continued under President Obama.
What is the Stuxnet virus?
Stuxnet is an example of a virus whose threat goes far beyond the digital sphere. Let’s learn more about the Stuxnet attack crippling Iran’s nuclear facilities. What is Stuxnet?

Is Duqu a Stuxnet-like worm?
Symantec believes that Duqu was created by the same authors as Stuxnet, or that the authors had access to the source code of Stuxnet. The worm, like Stuxnet, has a valid, but abused digital signature, and collects information to prepare for future attacks.
What is Duqu malware?
Duqu is a collection of computer malware discovered on 1 September 2011, thought to be related to the Stuxnet worm and to have been created by Unit 8200. Duqu has exploited Microsoft Windows ‘s zero-day vulnerability.
What do Stuxnet and Duqu have in common?
Because Stuxnet and Duqu were written on the same platform and share many of the same fingerprints in their source code, researchers believe both were developed by the same group of programmers.
