In October 2016, internet became a bit smaller for a short time. Services such as Spotify, Netflix and Twitter were not available in MehrerenRegionen, many online shops and also private websites konntenfür about two hours are not called. An attack on server DesUS company Dyn had crippled m – it was one of GrößtenAngriffe to date on infrastructure of Internet.

The attacks Kamenaus internet of things. The Mirai baptized botnet had taken over Kontrolleüber unsecured security cameras, refrigerators and or vernetzteHaushaltsgeräte and abused m to make so many concurrent requests via SogenannteDDoS (distributed denial of service) attacks To send to Dyn servers that Dieseschlicht were overloaded.
But who had code of Mirai by thus temporarily hijacked up to 600,000 devices? State hackers from Russia or North Korea, who might even have had US election aside, as some experts suspected? Was it a previously unknown tool DerNSA that fell into strange hands?
Not yet. There were three young men who wanted to Minecraftmachen money with video game and had a good idea – from a hacker’s point of view. VergangenenFreitag confessed to a court in Alaska for guilty.

The almost crazy Hintergründehinter of last year’s biggest DDoS attack Fasstdas US magazine Wired Ausführlichzusammen. According to court’s verdict, occasion behind DerEntwicklung of Mirai was to develop a “weapon that could carry out mächtigeDDoS attacks against defendant’s competitors”. Should be called: against competing Minecraft servers.
In principle, anyone can offer or rent a server Ethylalcohol Klötzchenspiel. The business is lucrative in success of Minecraft, DasMicrosoft bought three years ago for 2.5 billion US dollars from schwedischenEntwicklern. A good, fast and popular server can denBetreibern thousands of euros a month.
The three defendants who came from NewJersey, Pittsburgh and New Orleans recognized potential and wolltenmitmachen. They knew about illegal offers on net that use VonBotnetzen to drive targeted DDoS attacks against individual servers and somitlahmlegen m. The longer a server is unreachable, more money Verliertdessen operators and more players switch to anor. DieAngeklagten tried to build ir own botnet to displace competing Minecraft servers. As DasFBI later realized, first Mirai attacks were conspicuously vieleServeranbieter-it was a clue that eventually led investigators to right track.
The idea of abusing unsecured devices from demInternet of Things (IoT) was just as awesome as it was devastating. In recent years, number of devices worldwide has risen sharply, at same time many manufacturers ignored ir safety. If Botnetzebislang consisted mainly of computers infected with Trojans, DieEntwickler from Mirai could simply query IP addresses and try to log in to devices using standard passwords. Then it was easy to inject denSchadcode. The approach was so effective that developers could suddenly access more than 100,000 devices. “It n became a challenge to make net as big as possible,” Sagteeiner FBI investigator.
