This traffic just started today for the first time. The reporting device is a router. Nothing inside it has ever had its host file altered in any misguided Nachi defense. These hits are all on the external router interface, at the perimeter. Only one machine has been on that LAN during this period. Any ideas besides the traditional Nachi suggestions? No user activity at all was going on when this started. Notice also that the dest ports don't increment in a pattern that indicates normal human ephemeral port usage, and the intensity is not nearly high enough for anything Nachi-related. Some of the ports appear several times. I have not checked the machine out in person and do not have full packet captures. There could be evil on the LAN, or this could just be some odd probing going on from the outside. 2004-09-22 13:04:41 127.0.0.1 80 xx.xx.xx.xx 1898 2004-09-22 13:20:24 127.0.0.1 80 xx.xx.xx.xx 1530 2004-09-22 13:36:31 127.0.0.1 80 xx.xx.xx.xx 1713 2004-09-22 13:37:22 127.0.0.1 80 xx.xx.xx.xx 1969 2004-09-22 13:52:27 127.0.0.1 80 xx.xx.xx.xx 1841 2004-09-22 13:52:44 127.0.0.1 80 xx.xx.xx.xx 1337 2004-09-22 13:53:18 127.0.0.1 80 xx.xx.xx.xx 1097 2004-09-22 14:34:10 127.0.0.1 80 xx.xx.xx.xx 1237 2004-09-22 15:05:59 127.0.0.1 80 xx.xx.xx.xx 1284 2004-09-22 15:06:16 127.0.0.1 80 xx.xx.xx.xx 1780 2004-09-22 15:21:26 127.0.0.1 80 xx.xx.xx.xx 1653 2004-09-22 15:22:16 127.0.0.1 80 xx.xx.xx.xx 1909 2004-09-22 16:35:07 127.0.0.1 80 xx.xx.xx.xx 1096 2004-09-22 17:40:46 127.0.0.1 80 xx.xx.xx.xx 1530 2004-09-22 17:41:03 127.0.0.1 80 xx.xx.xx.xx 1794 2004-09-22 17:57:13 127.0.0.1 80 xx.xx.xx.xx 1209 2004-09-22 17:57:46 127.0.0.1 80 xx.xx.xx.xx 1969 2004-09-22 18:12:50 127.0.0.1 80 xx.xx.xx.xx 1841 2004-09-22 18:13:07 127.0.0.1 80 xx.xx.xx.xx 1337 2004-09-22 18:13:41 127.0.0.1 80 xx.xx.xx.xx 1097 2004-09-22 18:54:20 127.0.0.1 80 xx.xx.xx.xx 1237 2004-09-22 19:26:12 127.0.0.1 80 xx.xx.xx.xx 1284 2004-09-22 19:26:29 127.0.0.1 80 xx.xx.xx.xx 1780 2004-09-22 19:42:22 127.0.0.1 80 xx.xx.xx.xx 1909 2004-09-22 19:58:24 127.0.0.1 80 xx.xx.xx.xx 1827 2004-09-22 20:15:53 127.0.0.1 80 xx.xx.xx.xx 1898 2004-09-22 20:41:23 127.0.0.1 80 xx.xx.xx.xx 1530 2004-09-22 20:41:40 127.0.0.1 80 xx.xx.xx.xx 1794 2004-09-22 20:57:28 127.0.0.1 80 xx.xx.xx.xx 1713 2004-09-22 20:57:45 127.0.0.1 80 xx.xx.xx.xx 1209 2004-09-22 21:14:10 127.0.0.1 80 xx.xx.xx.xx 1097 2004-09-22 22:26:24 127.0.0.1 80 xx.xx.xx.xx 1284 2004-09-22 22:26:41 127.0.0.1 80 xx.xx.xx.xx 1780 2004-09-22 22:41:42 127.0.0.1 80 xx.xx.xx.xx 1653 2004-09-22 22:42:33 127.0.0.1 80 xx.xx.xx.xx 1909 2004-09-22 23:54:46 127.0.0.1 80 xx.xx.xx.xx 1096 _______________________________________________ Intrusions mailing list [email protected] http://www.dshield.org/mailman/listinfo/intrusions
