Thanks a lot who has replied to me. Basically 64.40.117.19 is foreign IP and connection from all over world means I've seen accesses from various different IPs to 64.40.117.119. Before client's connection was without firewall. I put firewall and also notified client's admin and now it seems like everything is fine. Ganbold news () dmcdonald net wrote:Joey, a text book case? Prehaps im missing something, but see nothinginGenbolds email which makes me consider XSS. XSS is often a smallamount oftraffic, with HTML and javascript in post request content or getrequestquery strings. Ganbold, In my opinion, it's more likely it's one of the following * brute force or dictionary attack on a login form, prehapsusing a botnetto mask the actual attacker * DDOS, again prehaps from a botnet * DOS, prehaps creating half open connects using a randomspoofed sourceaddresses (try and check to see if the addresses are random, orcome for afixed set of IPs). * Someone looking for hidden files and directories * An automated script scraping the website for dynamic or alarge amountof content, or some other tool which is malfunctioning * The website is just really popular and your client needs toupgradetheir kit Attempt to find out what kind of requests (if any) are beingsent to theserver, prehaps using a tool like wireshark, and that shouldtell you alittle about what is going on. Best, RenskiGanbold, This sounds like a textbook case of Cross Site Scripting (XSS). Consider filtering user output more carefully.

Connections are coming from all over the Internet (various different IPs) specifically to this IP. Due to this problem (I guess it is DDoS) one of our router'sCPUusage grew up to 100% and stopped a service for a while. What kind of problem this could be? Has anybody seen this kind of attack before? I appreciate if somebody can enlighten me in this regard. thanks in advance, Ganbold -- The more control, the more that requires control. _______________________________________________ Full-Disclosure - We believe in it.
