CyberSecurity: Someone is trying to take the internet down.

I have been reading a lot of DDOS attacks & recently found that DDOS attack is so powerful that it could take the whole internet down. As per many references & stories, it is already happening. Let me share some of the interesting stories. Things are scary but we all should be aware of the danger. It is not fictional Hollywood movies anymore. It is real now.

Story-1: The internet’s worst-case scenario finally happened in real life: An entire country was taken offline, and no one knows why

Abstract

For years, countries have worried that a hostile foreign power might cut the undersea cables that supply the world with internet service.  Late last month, we got a taste of what that might be like. An entire country, Mauritania, was taken offline for two days because an undersea cable was cut. 

The 17,000-kilometer African Coast to Europe submarine cable, which connects 22 countries from France to South Africa, was severed on March 30, cutting off web access partially or totally to the residents of Sierra Leone and Mauritania.

Story-2: 3 US hackers took out key parts of the internet in 2016 because they wanted to make money on Minecraft

Abstract

Three US hackers have pleaded guilty to creating the Mirai botnet, which took out some of the internet’s biggest sites last year including Reddit, Spotify, and Twitter through distributed denial of service (DDoS) attacks.

The goal of DDoS in Minecraft is to try and frustrate users on a rival server with slow service — so that they end up switching to yours.

Story-3: INSIDE THE CUNNING, UNPRECEDENTED HACK OF UKRAINE’S POWER GRID.

Abstract

One worker was organizing papers at his desk inside the Prykarpattyaoblenergo power grid control center, the cursor on his computer suddenly skittered across the screen of its own accord.

He watched as it navigated purposefully toward buttons controlling the circuit breakers at a substation in the region and then clicked on a box to open the breakers and take the substation offline. A dialogue window popped up on the screen asking to confirm the action, and the operator stared dumbfounded as the cursor glided to the box and clicked to affirm. Somewhere in a region outside the city, he knew that thousands of residents had just lost their lights and heaters

The operator grabbed his mouse and tried desperately to seize control of the cursor, but it was unresponsive. Then as the cursor moved in the direction of another breaker, the machine suddenly logged him out of the control panel. Although he tried frantically to log back in, the attackers had changed his password preventing him from gaining re-entry. All he could do was stare helplessly at his screen while the ghosts in the machine clicked open one breaker after another, eventually taking about 30 substations offline
