I can't tell from your email what indications you currently have thatthis came through the firewall and was not spoofed from the inside in some manner. I've always found the Netscreen to be a pretty secure device and this would be a serious flaw. Are there any other methods onto the network such as dial-in, VPN, or vendor connections? Attacks can originate from any of these without a flaw in the firewall software.
