Top 5 Biggest Cyber Attack in History!

 

5 The Estonian Cyberwar

The government of Estonia was subjected to cyber terrorism on April 27, 2007 by the Nashi, a pro-Kremlin group from Transnistria. One of the largest after Titan Rain, they employed a number of techniques such as ping floods and botnets to penetrate and take down key government websites rendering them useless. Their method was so complicated that the Estonian government believed that they might have had aids from the Russian government. What triggered these attacks was an important icon to the Russian people, the Bronze Soldier of Tallinn, an elaborate Soviet-era war grave marker and the war graves that were relocated by the Estonian government.

4 Epsilon

One of the costliest cyber attacks in history, the data breach in Epsilon, the world’s largest provider of marketing and handling services to industry giants such as JP Morgan Chase, Best Buy, and other major financial services, retailers and other major companies in 2011, has an estimated damage cost that ranged from $225 million to $4 billion dollars. The targets of the hackers were email addresses that they can use for their criminal activities, making its implications a lot greater than estimated.

3 Moonlight Maze

One of the earliest forms of major infiltration where hackers penetrated American computer systems at will; Moonlight Maze was an accidental discovery made by the US officials and was believed to be conceived by the Russians although they denied their involvement. In this cyber attack, hackers targeted military maps and schematics and other US troop configurations from the Pentagon, the Department of Energy, NASA and various universities and research labs in unremitting attacks that was discovered in March 1988, but had been going on for nearly two years.

2 Titan Rain

In 2004, Shawn Carpenter discovered a series of coordinated ‘cyber raids’, in what the FBI believed to originated from government-supported cells in China. Dubbed as ‘Titan Rain,’ hackers were able to infiltrate several computer networks including those at NASA and the Lockheed Martin, Redstone Arsenal, and Sandia National Laboratories. Considered as one of the biggest cyber attacks in history, these acts posed the dangers of not only making off with military intelligence and classified data, but also paved the way for other hackers and espionage entities to infiltrate these systems as they leave backdoors or ‘zombify’ these machines.

1 The Original Logic Bomb

During the cold war in 1982, the CIA found a way to disrupt the operation of a Siberian gas pipeline of Russia without using traditional explosive devices such as missiles or bombs. Instead, they caused the Siberian gas pipeline to explode using a portion of a code in the computer system that controls its operation in what they tagged as “logic bomb.” The chaos that ensued was so monumental that the resulting fire was even seen from space.
