(W32 \/ Stuxnet) is a computer worm that runs on Microsoft Windows and was discovered in June 2010. Stand-alone computer systems isolated from the Internet can also be infected by means via USB storage. Therefore, it is shocking that it causes infection and actual harm in industrial control systems that were previously believed to be relatively safe against attacks via the Internet [1], and was discovered in June 2010 in Iran. It became famous for its attacks targeting its nuclear facilities. [1] In addition, the Trojan horse malware that appeared in the fall of 2011, Duqu and Flame, are believed to be derived from Stuxnet.<br \/>\nWith the advancement of technology, cyber attacks are becoming more sophisticated. One of the typical malware in the 2010s is &#8220;Stuxnet&#8221;. Stuxnet is a malware allegedly created by the United States and Israel to attack a system that controls a centrifuge at a nuclear facility in Iran, and became a hot topic around 2010. It is said that the computer virus plan using this extremely advanced malware was called &#8220;Olympic Games&#8221;.<\/p>\n<p>The industrial control system for the uranium enrichment facility in Natanz, Iran, was not connected to the internet. One of the ways to improve security is called &#8220;air gap&#8221;. By using the network in a state of being physically isolated from the network such as the Internet, it can be expected to have the effect of protecting important information from cyber attacks from external networks. In order to break into a system or terminal that is not connected to an external network, a physical connection to an external medium such as a USB memory is required. The air gap was also thorough at the uranium enrichment facility in Natanz, but the industrial control system was infected via a USB memory.<\/p>\n<p>How Stuxnet Invaded Nuclear Facilities<\/p>\n<p>The main purpose of Stuxnet was to take control of the centrifuge used to enrich uranium in the facility and to nullify Iran&#8217;s nuclear tests and developments. Stuxnet exploited the vulnerability of Windows OS and attacked by targeting the vulnerability of the system control software of Siemens of Germany, and the operating conditions were limited, but it is characterized by its high autonomy. there was. Autonomy is one of the properties of AI, but Stuxnet has outstanding autonomy among malware, and it can be said that it is practically advanced AI.<\/p>\n<p>For example:<\/p>\n<p>Automatically checks your computer for zero-day vulnerabilities (security flaws that have not yet been addressed) when attached to your computer via USB<br \/>\nAfter infection, computers on the network are automatically searched for PLCs (programmable logic controllers, industrial automatic controllers) that control centrifuges.<br \/>\nImproperly manipulate the centrifuge settings, disrupt rotating equipment and drastically reduce enriched uranium production<br \/>\nFalsify sensor data such as pressure, rotation, and vibration between the administrator and the centrifuge to keep facility technicians out of the picture.<br \/>\nIssue a command to stop the warning signal issued by the sensor of the targeted device so that the administrator does not notice the malfunction.<\/p>\n<p>Malware with such advanced processing procedures (algorithms) seems to have no problem if there is an air gap, but in reality it is easy to secure security by human error of inserting a USB memory into a computer in the facility. It has been breached. In fact, it&#8217;s still not clear who plugged in the USB, but from a facility feature and security standpoint, it&#8217;s likely an internal person.<\/p>\n<\/section>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; \u30b9\u30bf\u30c3\u30af\u30b9\u30cd\u30c3\u30c8 \u30b9\u30bf\u30c3\u30af\u30b9\u30cd\u30c3\u30c8\uff08W32\/Stuxnet\uff09\u306f\u3001Microsoft Windows\u3067\u52d5\u4f5c\u3059\u308b\u30b3\u30f3\u30d4\u30e5\u30fc\u30bf\u30ef\u30fc\u30e0\u3067\u3042\u308a\u30012010\u5e746\u6708\u306b\u767a\u898b\u3055\u308c\u305f\u3002\u30a4\u30f3\u30bf\u30fc\u30cd\u30c3\u30c8\u304b\u3089\u9694\u96e2\u3055\u308c\u305f\u30b9\u30bf\u30f3\u30c9\u30a2\u30ed\u30fc\u30f3 [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[17,13],"tags":[],"_links":{"self":[{"href":"http:\/\/cyber-price.com\/buddha\/wp-json\/wp\/v2\/posts\/5454"}],"collection":[{"href":"http:\/\/cyber-price.com\/buddha\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/cyber-price.com\/buddha\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/cyber-price.com\/buddha\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/cyber-price.com\/buddha\/wp-json\/wp\/v2\/comments?post=5454"}],"version-history":[{"count":6,"href":"http:\/\/cyber-price.com\/buddha\/wp-json\/wp\/v2\/posts\/5454\/revisions"}],"predecessor-version":[{"id":5474,"href":"http:\/\/cyber-price.com\/buddha\/wp-json\/wp\/v2\/posts\/5454\/revisions\/5474"}],"wp:attachment":[{"href":"http:\/\/cyber-price.com\/buddha\/wp-json\/wp\/v2\/media?parent=5454"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/cyber-price.com\/buddha\/wp-json\/wp\/v2\/categories?post=5454"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/cyber-price.com\/buddha\/wp-json\/wp\/v2\/tags?post=5454"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
