Few weeks ago, I randomly scanned certain range of IP address.
With normal ping, this would be the result:
| root@X-Program:~# ping 192.168.0.5 PING 192.168.0.5 (192.168.0.5) 56(84) bytes of data. 64 bytes from 192.168.0.5: icmp_seq=1 ttl=250 time=89.3 ms 64 bytes from 192.168.0.5: icmp_seq=2 ttl=250 time=68.2 ms 64 bytes from 192.168.0.5: icmp_seq=3 ttl=250 time=126 ms 64 bytes from 192.168.0.5: icmp_seq=4 ttl=250 time=52.7 ms— 192.168.0.5 ping statistics — 4 packets transmitted, 4 received, 0% packet loss, time 3000ms rtt min/avg/max/mdev = 52.741/84.220/126.547/27.677 ms |
This might look normal for you guys, but to me, IT’S WAY F**KING WEIRD (to respect the Ramadhan month, I censored it).
I shouldn’t have that range of IP address, especially when I’ve configure the router to accept IP address from 192.168.1.2 until 192.168.1.254.
*note: 192.168.1.1 is gateway and 192.168.1.255 is broadcast*
So I’ve decide to enumerate this illegal hosts and this is the result:
| root@X-Program:~# nmap 192.168.0.2-15 -sS -sV -P0 –osscan-guess Starting Nmap 4.20 ( http://insecure.org ) at 2007-09-12 18:09 MYT Stats: 0:00:30 elapsed; 0 hosts completed (5 up), 5 undergoing SYN Stealth Scan SYN Stealth Scan Timing: About 3.49% done; ETC: 18:12 (0:02:19 remaining) All 1697 scanned ports on 192.168.0.2 are filteredAll 1697 scanned ports on 192.168.0.3 are filtered All 1697 scanned ports on 192.168.0.4 are filtered Interesting ports on 192.168.0.5: Interesting ports on 192.168.0.6: Service Info: OS: IOS; Device: router |
Ok, now it’s much more weird and threaten my home network.
Check out the port name: “krb524″ and “kuang2″.
krb524: Kerberos v5/ CrackDown/ Prosiak/ Swift Remote more information
kuang2: Some old virus more information
Also, check out the device info: router.
Dude! It’s a freaking ROUTER with 2 trojan port!
Too weird for this exist at my home network and it’s superbly dangerous if it’s being ignored.
So I block IP address from 192.168.0.2 to 192.168.0.254 with port from 2 until 65530.
Here’s some screenshot of the Nmap.
Just wanna wish all of muslim, happy fasting!
