Generate text that refutes this claim: Cyber attacks are difficult to trace  Cyber attacks are very difficult to trace as cyber attackers hide their digital tracks [20]. Cyber attackers also often launch attacks from poorly protected computers in other countries, which in no way implicates that the state was responsible for attacks – for instance, roughly 10% of spam comes from computers in China, but that is not Chinese spam [21]. The situation is different with traditional warfare, where there is evidence of weapons used, uniforms spotted, and reports of witnesses on site. Of course, we can expect states to lie about launching cyber attacks, thus China and the USA trade accusations about responsibility for cyber attacks, but there is no good way to test the truth. All of this means that an act of war would be judged based on incomplete and misleading information about another state’s involvement, threatening international peace and resulting in the loss of human life for no good reason.

It is unlikely that states would freely attack other states when there is unclear evidence as to who the perpetrator was. In any country that is going to engage in military action regardless of the reason there is intense public debate this would apply all the more if the reason was novel (for instance, those on interfering against Syria's Assad's regime), so we can expect public scrutiny to apply to cyberwarfare as well.  Furthermore, there are also cases when cyber attacks can be traced to a particular country hostile country or even particular group within the country. This can happen when the country or groups within it themselves admit to the attack, as the Syrian Electronic Army, sympathetic to Assad's regime, cyber attacking USA in 2013 [22]. Or through intensive investigation. Tools to track cyber attacks are also constantly being perfected. For example, IPv6 (the latest version of the internet protocol) is the most effective at decreasing anonymity of cyber attackers [23]. So there are scenarios when cyber attackers are known and can be tracked, and the states have a right to treat them as acts of war.
