What is cyberwar?

At its core, cyberwarfare is the use of digital attacks by one country or nation to disrupt the computer systems of another with the aim of create significant damage, death or destruction.

What does cyberwarfare look like?

Cyberwar is still an emerging concept, but many experts are concerned that it is likely to be a significant component of any future conflicts. As well as troops using conventional weapons like guns and missiles, future wars will also be fought by hackers using computer code to attack an enemy's infrastructure.


Governments and nation states are now officially training for cyberwarfare: An inside look

Europe, Canada, USA, Australia, and others are now running training exercises to prepare for the outbreak of cyberwar. Locked Shields is the largest simulation and TechRepublic takes you inside.

Governments and intelligence agencies worry that digital attacks against vital infrastructure -- like banking systems or power grids -- will give attackers a way of bypassing a country's traditional defences.

This is surely no frivolous hacker feud, but an incredibly sophisticated attack on the US cyber-security infrastructure — even though it was meant to look like it was carried out by Guy-Fawkes-mask-wearing ideological warriors, at least a bit. It even features a quasi-illiterate intro/rant railing against “the elites.” It’s a familiar refrain in an American political season dominated by anti-establishment politicians, and it fits well with the stereotype of the libertarian hacker — but it also seems to want to convince these elites not to support the sort of offensive hacking on display in their leak. Emphasis added:

We want make sure Wealthy Elite recognizes the danger cyber weapons, this message, our auction, poses to their wealth and control. Let us spell out for Elites. Your wealth and control depends on electronic data. You see what “Equation Group” can do. You see what cryptolockers and stuxnet can do. You see free files we give for free. You see attacks on banks and SWIFT in news. Maybe there is Equation Group version of cryptolocker+stuxnet for banks and financial systems? If Equation Group lose control of cyber weapons, who else lose or find cyber weapons? If electronic data go bye bye where leave Wealthy Elites? Maybe with dumb cattle?

"We've switched from cyber-espionage to offensive cyber action," Hyppönen told El Reg. "The cyber arms race is just beginning and it's going to get much worse."

Ohne das Internet geht heute fast nichts mehr, nahezu alles hängt irgendwie am Netz. Private, geschäftliche und auch staatliche Kommunikation ist ohne das World Wide Web beinahe undenkbar geworden. Aber auch Straßenverkehr, Handel und Infrastruktur sind ohne das Internet völlig lahmgelegt. Das Internet ist für das Funktionieren eines Landes genauso essenziell wichtig wie das Strom- oder Straßennetz. Und damit ist es ein taktisches Ziel in potenziellen Kriegen. Genau darauf scheint sich ein unbekannter Staat nun intensiv vorzubereiten.

Davor warnt der renommierte Sicherheitsforscher Bruce Schneier. In einem Eintrag des Sicherheitsblogs "Lawfare Blog" berichtet der vom "Economist" schon als "Sicherheits-Guru" gerühmte Schneier über mysteriöse Angriffe auf die Grundpfeiler des Internets an sich. Eine ganze Reihe von sicherheitsrelevanten Firmen und Webseiten sei in den letzten beiden Jahren Opfer gezielter Attacken geworden, erklärt Schneier. Als hätte jemand vor, die Infrastruktur des Internets lahmzulegen.

Der Nachrichtendienst NSA ist offenbar Opfer eines Hackerangriffs geworden. Bereits 2013 erbeutete Überwachungsprogramme wurden jetzt im Internet veröffentlicht. Edward Snowden vermutet russische Hintermänner. Für die NSA könnte der Hack unangenehme Folgen haben.

Last Friday, a mysterious group by the name of “The Shadow Brokers” dumped what appeared to be some of the National Security Agency’s hacking tools online. There was some speculation as to whether the tools were legitimate. According to The Intercept, these tools are mentioned in documents leaked by NSA whistleblower Edward Snowden.
