If one of the common uses of XSS is to steal cookies which will be sent to the attacker's server, isn't it so easy to identify the attacker?

This is not like a SQLi for example which you can exploit using VPNs and proxy chains. In this case you have to provide a URL that you can control for retrieve the host, therefore, you can be easily tracked. Am I wrong?

And you base your opinion in? – Ayozint Jun 24 '13 at 11:55
Because you already made your conclusion for one – Lucas Kauffman Jun 24 '13 at 12:25
That's a question, not a conclusion. – Ayozint Jun 24 '13 at 12:26
I have to agree with @LucasKauffman here. This question is rhetorical, and discussing an inherent property of an XSS exploit - that it's cross-site. The XSS hosting server could as well have been exploited, you would have no way of knowing the requests are not forwarded to another server, those to another server, e.t.c. ad infinitum. Assuming the XSS hosting server was not exploited - well then you've already answered your question, attacker's IP would be the one the requests are forwarded to. The answer could then be: It varies from extremely easy to nigh impossible. Not constructive. ;) – TildalWave Jun 24 '13 at 12:47

Only beginners would employ their own domain to execute the cookie-stealing attack described. Most attackers will use a compromised domain, usually vulnerable to a public exploit.

Hence, any tracking activities will almost certainly lead to a compromised web application, without providing information about the real attacker.

Furthermore, an attacker exploititing a Stored XSS vulnerability can do it behind a VPN or a proxy, effectively conceiling his/her own position and identity.
