A Network hack [Netbios Hacking]

This Netbios Hacking guide will tell you about hacking remote computer and gaining access to its hard disk or printer .Netbios hack is the easiest way to break into a remote computer  

Step 1: Open command prompt

Step 2: In the command prompt use the “net view” command
( OR YOU CAN ALSO USE “NB Scanner” OPTION IN “IP-TOOLS” SOFTWARE BY ENTERING RANGE OF IP ADDRESSS.BY THIS METHOD YOU CAN SCAN NUMBER OF COMPUTERS AT A TIME).

Example: C:>net view \59.43.45.212

The above is an example for operation using command prompt.”net view” is one of the netbios command to view the shared resources of the remote computer.Here “59.43.45.212? is an IP address of remote computer that is to be hacked through Netbios.You have to substitute a vlaid IP address in it’s place.If succeeded a list of HARD-DISK DRIVES & PRINTERS are shown.If not an error message is displayed. So repeat the procedure 2 with a different IP address.

Step 3: After succeeding, use the “net use” command in the command prompt.The “net use” is another netbios command which makes it possible to hack remote drives or printers.

Example-1:
C:>net use D: \59.43.45.212F
Example-2:
C:>net use G: \59.43.45.212SharedDocs
Example-3: 
C:>net use I: \59.43.45.212Myprint


NOTE: In Examples 1,2 & 3, D:,G: & I: are the Network Drive Names that are to be created on your computer to access remote computer’s hard-disk.

NOTE: GIVE DRIVE NAMES THAT ARE NOT USED BY ANY OTHER DRIVES INCLUDING HARD-DISK DRIVES,FLOPPY DRIVES AND ROM-DRIVES ON YOUR COMPUTER.THAT IS IF YOU HAVE C: & D: AS HARD DIRVES, A: AS FLOPPY DIVE AND E: AS CD-DRIVE, GIVE F: AS YOUR SHARED DRIVE IN THE COMMAND PROMPT

F:,”SharedDocs” are the names of remote computer’s hard-disk’s drives that you want to hack. “Myprint” is the name of remote computer’s printer.These are displayed after giving “net use” command. “59.43.45.212? is the IP address of remote computer that you want to hack.

Step 4: After succeeding your computer will give a message that “The command completed successfully“. Once you get the above message you are only one step away from hacking the computer.
[ad code=1 align=center]
Now open “My Computer” you will see a new “Hard-Disk drive”(Shared) with the specified name.You can open it and access remote computer’s Hard-Drive.You can copy files,music,folders etc. from victim’s hard-drive.You can delete/modify data on victim’s hard-drive only if WRITE-ACCESS is enabled on victim’s system.You can access filesfolders quickly through “Command Prompt”.

NOTE: If Remote Computer’s Firewall Is Enabled Your Computer Will Not Succeed In Gaining Access To Remote Computer Through Netbios.That is Netbios Hacking Is Not Possible In This Situation.(An Error Message Is Displayed).So Repeat The Procedure 2,3 With Different IP Address.

10 System Admin Tools to Help You Secure Your Network

System admins are frequently bombarded with security concerns, requests, alerts, news items, “did you see this?!” emails, and more. Keeping up with all the aspects of network security can seem like an overwhelming task, but in this post we’re going to look at ten tools a system admin can use to help secure their network. Some you may be familiar with, like network security software, while others may come as a surprise, like your email client; but all will help you to stay ahead of the bad guys, keep yourself informed of the latest threats, and maintain the security of your network. 

1. Network security software

When we talk about network security software, we’re talking about a class of product more than any specific tool, and how important it is for you to have an application or small group of applications that can help you to accomplish most of your tasks. There are simply too many things for any one admin to do by hand, and network security software applications help to automate the heavy lifting and ensure that you can keep up with the workload. Look for network security software that multitasks. Think about it as a Swiss Army knife of software packages that includes many of the other items on this list.

2. Vulnerability scanner

A good vulnerability scanner is a key part of any toolkit, and should be used by server admins and security engineers alike. The top network security software apps will include a scanner that has a database of the thousands of vulnerabilities that could exist on your network, so that you can quickly, easily and regularly scan your network to ensure you systems are up-to-date, configured properly and secured.

3. Port scanner

A port scanner is another regular tool that should be in your network security software application. Attackers regularly scan your Internet connection looking for ways in and so should you. But you should also scan internally so you can find unauthorized services or misconfigured systems, and to validate your internal firewalls are set up correctly.

4. Patching software

Patching operating systems and third party applications is one of the most important, regularly recurring tasks a sys admin has. Network security software that can automate this, and handle the hundreds of other applications on your network, is the only realistic way you can keep up with this.

5. Auditing software

Auditing software may strike you as a strange recommendation at first, but consider all those apps you are trying to patch. How can you be sure you have no vulnerabilities on your systems if your users can install anything on your systems? How are you going to maintain licensing compliance if you don’t know who has installed what from \software? Network security software may also include software and hardware inventory components to help you stay informed and secure.

6. Secure remote clients

Telnet, older versions of PCAnyWhere and several of the web-based remote access apps that are out there all have a common issue - they’re not secure. Use SSH v2 or later for secure access to all CLI-based systems, and the most secure versions of Remote Desktop Protocol to manage Windows boxes. Using strong encryption, good passwords, lockout policies and, when possible, mutual authentication between client and host, will help to ensure no one sniffs credentials or brute-forces their way into a system. If you have two-factor authentication in your environment, ensure that every system possible uses it to further reduce your risk from unauthorized access.

7. A good network analyzer

Whether you like the open source WireShark, the free Microsoft tool NetMon, or one of the many other commercial network analysis tools, having a good “sniffer” is key to helping secure and analyze systems. There is simply no way that’s more effective to figure out just what is going on between networked systems than to see the traffic first hand.

8. Network tools

Whenever you are dealing with connections from foreign systems, you will find the need to check network addresses, routes and more. Having good tools like DIG, WHOIS, HOST, TCPING and others close at hand makes network evaluation a breeze.

9. Log parsing software

Securing systems means going through logs; lots of them. Web logs, access logs, system logs, security logs, SNMP logs, syslog logs – the list goes on and on. Having software that can quickly and easily parse through logs is critical. Everyone has their favorite. Some install locally like LogParser, while others run on servers like Splunk. Whichever you prefer, get a good log parser to help wade through what can be millions of entries quickly and easily so you can find events you need to check.

10. Your email client

Knowledge is power, and the best way to amass that knowledge is to stay informed. Whether you subscribe to email bulletins, security alerts, or RSS feeds, your email client can provide you the first indications that something new is out there, and also what you need to do to protect your systems from the threat. Zero day exploits, out of band patches, best practices and more, can all be yours if you simply join the right distribution lists and subscribe to the right lists.

These 10 system admin tools are a great start towards building your toolkit for security. Network security software plays a major role in this toolkit, which you supplement with other tools and the information you need to maintain a secure environment.
