Top 12 Biggest Cyber Attacks in The World

Here is the list of top Cyber Attacks that happened in the world.

1.In 1988, a cyber attack had happened on embassies of Sri Lanka with 800 emails a day. The message which was appearing was “We are the Internet Black Tigers and we are doing this to disrupt your communications.” Department of Intelligence characterizes the attack as a terrorist attack on government computer systems.

2.On 3 June 1998, the "mealworm" hacking group attacked Web site of the Indian Bhabha Atomic Research Centre and stole e-mails from the same center. The three anonymous saboteurs through online interviews claimed that.

3.In July 1997, the leader of the Chinese hacker group claimed that temporarily disallowed Chinese satellite and announced that hackers set up a new global organization to protest and prevent investment by Western countries in China.

4.In 1998, at the time of parliamentary elections in Sweden, Anonymous attacked the Web site of the political party pornographic sites. The same month, saboteurs attacked the website of the Mexican government in protest against government corruption and censorship. 

Romanian hackers on one occasion managed to intrude into the computer systems controlling the life support systems at an Antarctic research station, endangering the 58 scientists involved. Fortunately, their activity is stopped before any accident occurred. 

5.During the Kosovo conflict, Belgrade hackers conducted a denial of service attack (DoS) on the NATO servers. They typically used for diagnostic or control purposes or generated in response to errors in IP operations. 

6.During the Palestinian-Israeli cyberwar in 2000, ProPalestinian hackers used DoS tools to attack Israel’s ISP, Netvision managed to resist subsequent attacks by increasing its safety.

7.In late 2008, when a  group of hackers called the “Greek Security Team”, “intrude” into CERN computer systems (European Center for Nuclear Research) so deep, that they were very close to taking control of one of the detectors at LHC (Large Hadron Collider), whose aim was to defame the experts responsible for the computer system, calling them “a group of students.” 

8.In April 2007,  the “Associated Press” reported that cyber attacks on critical information infrastructure on Estonia  DoS attacks carried out by different locations around the world (U.S., Canada, Brazil, Vietnam, and other locations). Of course, the locations of the computers involved in the attack do not always show the location of the direct participants in the attack. It is actually the location of the so-called “zombie” machines that act as intermediaries during the attack, without their knowledge or without any knowledge of the direct attackers. The attack completely put out the function of the Web sites of many governmental, media, and Þ financial institutions and leads to diplomatic talks which were a reason to examine the possibility of creating a NATO-supported research center capable of identifying the source of cyberattacks. In August 2008, a similar attack was conducted against Georgia. It is assumed that the attack was perpetrated by Russian hackers.

9.In 2007, hackers attacked the Ukrainian President Viktor Yushchenko's website. The attack was carried out by the radical Russian nationalist youth group, the Eurasian Youth Movement.

An analyst from the U.S. Central Intelligence Agency (CIA) publicly revealed that in January 2008, hackers successfully stopped power supply networks in several U.S. cities. 

In November 2008, the Pentagon had a problem with cyber attacks carried out by computer virus, prompting the Department of Defense (DoD) to take the unprecedented step of banning the use of external hardware devices, such as flash memory devices and DVDs.Officially, the U.S. never felt a cyber-terrorist attack.
