Stuxnet worm

A sophisticated worm designed to steal industrial secrets and disrupt operations . the worm was discovered in July when researchers at VirusBlokAda found it on computers in Iran.The worm, was designed to attack Siemens industrial control systems.Stuxnet could be used to cause a significant amount of damage if it is not properly removed.Researchers at Symantec have cracked Stuxnet's cryptographic system, and they say it is the first worm built not only to spy on industrial systems, but also to reprogram them

Once installed on a PC, Stuxnet uses Siemens' default passwords to seek out and try to gain access to systems that run the WinCC and PCS 7 programs -- so-called PLC (programmable logic controller) programs that are used to manage large-scale industrial systems on factory floors and in military installations and chemical and power plants.this malware spreads with the help of us drive or lan

How To Find Vulnerable Web Apps With Google : Web Application Hacking

Search engines index a huge number of web pages and other resources. Hackers can use these engines to make anonymous attacks, find easy victims, and gain the knowledge necessary to mount a powerful attack against a network. Search engines are dangerous largely because users are careless. Further, search engines can help hackers avoid identification. Search engines make discovering candidate machines almost effortless. Listed here are a few common hacks performed with http://www.google.com (which is our favorite search engine, but you can use one of your own choosing if you'd like, assuming it supports all the same features as Google).

To find unprotected /admin, /password, /mail directories and their content, search for the following keywords in http://www.google.com:

• "Index of /admin"
• "Index of /password"
• "Index of /mail"
• "Index of /" +banques +filetype:xls (for France)
• "Index of /" +passwd
• "Index of /" password.txt

To find password hint applications that are set up poorly, type the following in http://www.google.com (many of these enumerate users, give hints for passwords, or mail account passwords to an e-mail address you specify!):

• password hint
• password hint -email
• show password hint -email
• filetype:htaccess user

To find IIS/Apache web servers with FrontPage installed, type the following in http://www.google.com (run the encrypted password files through a password cracker and get access in minutes!):

         administrators.pwd index
         authors.pwd index
          service.pwd index
          allinurl:_vti_bin shtml.exe

To find the MRTG traffic analysis page for websites, type the following in http://www.google.com:

• inurl:mrtg

To get access to unprotected global.asa(x) files or to get juicy .NET information, type the following in http://www.google.com:

• filetype:config web (finds web.config)
• global.asax index (finds global.asax or global.asa)

To find improperly configured Outlook Web Access (OWA) servers, type the following in http://www.google.com:

• inurl:exchange inurl:finduser inurl:root

How To hack A Computer In A LAN By Creating a Null Session

Today,I will write about hacking computer inside the LAN network.

This technique will be taking advantage of Port 139.

Most of the time,Port 139 will be opened.

First of all,I will do a port scanning at the target computer which is 192.168.40.128.

This computer is inside my LAN network.

I will scan it using Nmap.

I get the result and it shows Port 139 is opened up for me.

Now you will need both of these tools:

** USER2SID & SID2USER

** NetBios Auditing Tool

You can get both of them on the Internet.

After you get both of them,put them in the C:\ directory

You now need to create a null session to the target computer.

Now open the Command Prompt and browse to the USER2SID & SID2USER folder.There will be 2 tools inside it,one will be USER2SID and another one will be SID2USER.

We will first using USER2SID to get the ID.

We will test against the Guest account because Guest account is a built in account.

After we get the ID,we need to do some modification on the ID.

We take the ID we get from the guest account and modified it become

"5 21 861567501 1383384898 839522115 500".

Please leave out the S-1-,leave out all the - too.

Now you will see that you get the username of the Administrator account.

In this case,the Administrator account is Administrator.

Create a text file called user.txt and the content will be the username of the Admin account.

Prepare yourself a good wordlist.

  

Now put both of them in the same directory with the NetBios Auditing Tool.

Press on enter and the tool will run through the passlist.

In this case,I have get the password.

In order to proof that I can get access to the target computer using this password.

After you press enter,it will prompt you for the username and password.

Therefore,just input them inside the prompt and continue.

Target C drive will be on your screen.

In order to prevent from this attack,close down port that you do not want to use such as Port 135,Port 136,Port 137,Port 138 and Port 139
