Once persistently installed on a target machine using separate CIA exploits, the malware scans visible WiFi access points and records the ESS identifier, MAC address and signal strength at regular intervals. To perform the data collection the target machine does not have to be online or connected to an access point; it only needs to be running with an enabled WiFi device. If it is connected to the internet, the malware automatically tries to use public geo-location databases from Google or Microsoft to resolve the position of the device and stores the longitude and latitude data along with the timestamp.
It was a marksman's job. The worm consists of a layered attack against three different systems: Windows infection[ edit ] Stuxnet attacked Windows systems using an unprecedented four zero-day attacks plus the CPLINK The techniques and tactics used in a cyberwar and a vulnerability used by the Conficker worm .
It is initially spread using infected removable drives such as USB flash drives  which contain Windows shortcut files to initiate executable code. Two websites in Denmark and Malaysia were configured as command and control servers for the malware, allowing it to be updated, and for industrial espionage to be conducted by uploading information.
Both of these domain names have subsequently been redirected by their DNS service provider to Dynadot as part of a global effort to disable the malware. Doing so intercepts communications between the WinCC software running under Windows and the target Siemens PLC devices that the software is able to configure and program when the two are connected via a data cable.
In this way, the malware is able to install itself on PLC devices unnoticed, and subsequently to mask its presence from WinCC if the control software attempts to read an infected block of memory from the PLC system.
It only attacks those PLC systems with variable-frequency drives from two specific vendors: Vacon based in Finland and Fararo Paya based in Iran.
The industrial applications of motors with these parameters are diverse, and may include pumps or gas centrifuges. Removal[ edit ] Siemens has released a detection and removal tool for Stuxnet.
Siemens recommends contacting customer support if an infection is detected and advises installing Microsoft updates for security vulnerabilities and prohibiting the use of third-party USB flash drives.
Symantec's Liam O'Murchu warns that fixing Windows systems may not completely solve the infection; a thorough audit of PLCs may be necessary.
Despite speculation that incorrect removal of the worm could cause damage,  Siemens reports that in the first four months since discovery, the malware was successfully removed from the systems of 22 customers without any adverse impact.
Control system security Prevention of control system security incidents,  such as from viral infections like Stuxnet, is a topic that is being addressed in both the public and the private sector.
In JulyINL and Siemens publicly announced flaws in the control system at a Chicago conference; Stuxnet exploited these holes in The basic premise that all of these documents share is that prevention requires a multi-layered approach, often referred to as " defense-in-depth ".

Please update this article to reflect recent events or newly available information. December Experts believe that Stuxnet required the largest and costliest development effort in malware history. The leading force behind Stuxnet is the cyber superpower — there is only one; and that's the United States.
Twenty-seven days later, the worm went back into action, slowing the infected centrifuges down to a few hundred hertz for a full 50 minutes. The stresses from the excessive, then slower, speeds caused the aluminium centrifugal tubes to expand, often forcing parts of the centrifuges into sufficient contact with each other to destroy the machine.
Iranian technicians, however, were able to quickly replace the centrifuges and the report concluded that uranium enrichment was likely only briefly disrupted. Assuming Iran exercises caution, Stuxnet is unlikely to destroy more centrifuges at the Natanz plant. Iran likely cleaned the malware from its control systems.
To prevent re-infection, Iran will have to exercise special caution since so many computers in Iran contain Stuxnet. Although Stuxnet appears to be designed to destroy centrifuges at the Natanz facility, destruction was by no means total. Moreover, Stuxnet did not lower the production of low-enriched uranium LEU during LEU quantities could have certainly been greater, and Stuxnet could be an important part of the reason why they did not increase significantly.
Nonetheless, there remain important questions about why Stuxnet destroyed only 1, centrifuges. One observation is that it may be harder to destroy centrifuges by use of cyber attacks than often believed.
This computer worm is designed to transfer data about production lines from our industrial plants to locations outside Iran. With more than 30, IP addresses affected in Iran, an official said that the infection was fast spreading in Iran and the problem had been compounded by the ability of Stuxnet to mutate.
Iran had set up its own systems to clean up infections and had advised against using the Siemens SCADA antivirus since it is suspected that the antivirus was actually embedded with codes which update Stuxnet instead of eradicating it.
According to Reuters, he told reporters at a news conference in Tehran, "They succeeded in creating problems for a limited number of our centrifuges with the software they had installed in electronic parts.

"Cyber Warfare: Techniques, Tactics and Tools for the Security Practitioners" is a consolidation of the current thinking around the topic of cyber warfare; not the way you hear about in the media where everything is a war of some kind (War on drugs, War on Terrorism, etc) but a discussion about what it means to conduct warfare via cyberspace/5(37).
