A different kind of Christmas scan
Those familiar with port scanning tools (like nmap), have probably heard of the Xmas scan option. This scanning strategy sets some unusual TCP flags, as the man page describes it:
Sets the FIN, PSH, and URG flags, lighting the packet up like a Christmas tree.
Yesterday, my firewall was systematically scanned with a combination of IPv4/IPv6 and TCP/UDP — not in Xmas scan mode — but the resulting Fireplot sure set the Christmas mood anyway!
Merry Christmas!
