Netcraft is a toolbar which helpful for you to secure yourself by Phishing attack.You see a view of toolbar given below...

Why use the Netcraft Toolbar?

• Protect your savings from Phishing attacks.
• See the hosting location and Risk Rating of every site you visit.
• Help defend the Internet community from fraudsters.

The Toolbar community is effectively a giant neighbourhood watch scheme, empowering the most alert and most expert members to defend everyone within the community against phishing attacks. Once the first recipients of a phishing mail have reported the target URL, it is blocked for community members as they subsequently access the URL. Widely disseminated attacks (people construct phishing attacks send literally millions of emails in the expectation that some will reach customers of the bank) simply mean that the phishing attack will be reported and blocked sooner.

Browse in Safety

The Netcraft Toolbar also:

• Traps suspicious URLs containing characters which have no common purpose other than to deceive.
• Enforces display of browser navigational controls (toolbar & address bar) in all windows, to defend against pop up windows which attempt to hide the navigational controls.
• Clearly displays sites' hosting location, including country, helping you to evaluate fraudulent urls (e.g. the real citibank.com or barclays.co.uk sites are unlikely to be hosted in the former Soviet Union).

So download and try out the toolbar now and protect yourself on the web.

SpyDLLRemover Tool

This post about Spy DLL Remover.I am found this tool by my Security partner "SecurityXploded". This tool works very good,it remove all unwanted DLL from your system.

SpyDllRemover is the specialized tool for detecting spyware & hidden Rootkit in the System.It can also detect & remove user-land Rootkit processes as well as other spyware processes using multiple Rootkit detection algorithms coupled with in-house Process Heuristics.This makes it a generic tool for detecting & removing any known as well as unknown threats compared to traditional Antivirus Software which can detect only Know threats.

Though this tool is useful to novice users, it is mainly designed to help the analysts to uncover spyware elements which are missed by Antivirus softwares. So this tool can also be used along side the traditional Antivirus softwares to effectively detect & protect against known as well as unknown threats. In addition to this, to protect your computer from identity theft, learn identity theft facts at lifelock.com, they highly recommend having a strong firewall, and strong passwords to protect your computer from being hacked.

I am given you my personal view,i am very satisfied with this tool and given my thank to SecurityXploded for introduse me with this tool.

How To Stop SQL Injection On Your Website

Website Hacking always hot topic between Hacker,some days before i am tell you how to hack a website by SQL Injection with picture.

For watch old Post Click Here

Today post about How to Safe your site against SQL Injection Attack because security of website too important for save your Data Base by access unauthorised person.

If your site SQL vulnerable then a hacker go to site login page and type tha administrator username and in the password field type or paste like this..

x' or '1'='1

If the site vulnerable then it login and you change all settings but how this code work.If you are able to log in then the code on side ...

$sql=

"SELECT*FROM users

"WHERE username="" . $username .

" AND password="" . $password ."";

then your code work as...

SELECT *FROM users WHERE username='admin' and PASSWORD='HrDe' or '1'='1

Here x' or '1'='1 has injected an extra phrase into the WHERE clause that means WHERE is always true,and this query will return a row contain the user's details.

If single user defined in the DB,then user's details will always returned else multiple users then one of those user will be returned at random.

How to safe website by Deface ?

How to fix vulnerable hole on your website,it's not difficult.Many ways to do it.If you work with MySQL then simply you fix it by using the

mysql_escape_string()

or

mysql_real_escape_string() function for example....

$userid=mysql_real_escape_string($userid);

$password=mysq;_real_escape_string($password);

$sql=

"SELECT*FROM users

"WHERE username="" . $username .

" AND password="" . $password ."";

This work as...

SELECT*FROM users WHERE username='admin' and PASSWORD='x\' or \'a\' =\'a

It backslashes(\) make the DB treat query like a normal character rather than as a delimiter,by it DB no interprets the SQL an OR in the WHERE clause.

This is one method but many ways open for you to protect yourself.

If this information helpful for you,so only enter your name and email id and write down your comment.

So if you are ready so let's start...

STEP 0: First find vulnerable site by use of this given Dorks...

"inurl:admin.asp"

"inurl:login/admin.asp"

"inurl:admin/login.asp"

"inurl:adminhome.asp"

"inurl:newsdetail.php"

"inurl:shop.php"

You search Google Uncle for more Dork.

STEP 1: At first step we check a site vulnerable or not,here i am use some picture for help you to understand all step clear fully,i am access this site DB but not hack it because i am a Ethical Hacker and do everything only for knowledge and save other person by Black site Hacking.well come on our topic,here we test the this site vulnerable or not.For this i am add only ' in end of URL for example...

CODE:

http://www.sitename.com/newsdetail.php?id=10'

You see a error page like given below page,i am show error with red line,if you not find it go to other site and use same step.

STEP 2: After find vulnerable site i am going found number of columns in your site. Add only order by 1,2,.... and -- end of your Site URL like i am check column

http://www.sitename.com/newsdetail.php?id=10 union all 1,@@version,3--

It shown DB and his name like given below...

STEP 4: Here we find table name for it use this code...

http://www.sitename.com/newsdetail.php?id=10 union select 1,table_name,3 from information_schema.table--

This line shown you table name like given below...

STEP 5: Here i am going get the column name of site.For this we use this code...

Complete Tutorial On Sniffing

This tutorial given you a complete introduction about Sniffing.Sniffers mainly developed for debugging network problems.Sniffers could capture,interpret and save packets sent across a network.This helpful for admin to later analyze captured packets and debug or troubleshoot network problems.

In market you found many type of sniffers but most used sniffer is Ethernet-based Sniffer.This Sniffer works with NIC(Network Interface Card).With Ethernet-based Sniffer NIC works in a special state called Promiscuous Mode.This mode ensure that your sniffer receives all the packets within specified range of system.

Sniffers can't catch packets traversing beyond switches and routers.

Sniffer dangerous for you,if an attacker used it against you after install on your system,your all data,password,private messages,e-mail and so on -get captured.

Protocol like FTP,POP,IMAP and HTTP are vulnerable to the sniffers.

Type of Attack:

Sniffer Attack consider as a Passive attack.A passive attack is one that doesn't directly intrude onto a foreign network or computer.

Making Sniffer Hard To Detect:

There is a method to help make it more difficult to detect a sniffer on a network. For this to work, you have to deploy two NICs in on computer. For the first NIC, configure the interface with the address of 0.0.0.0. This will allow the sniffer to monitor traffic but to not be detected. But there is still the issue of messages and alerts which will be handed off from the card the sniffer is on to another card to finish being delivered. The second card has a regular address but is not in promiscuous mode so it will be very hard for someone to detect this type of setup.

Save Yourself:

Kitty Litter The Anti-Sniffer is a handy application that can prevent hackers from capturing logins and passwords and viewing traffic on your wireless network by spamming thousands of false-leads per second that are unidentifiable from your regular browsing habits.
