What is SPAM?

It is really difficult to define spam. But generally speaking, spam is unsolicited information, which is forced upon the reader and is purported to advertise some service or product. The unsolicited information is not provided just once or twice; the reader is, in fact, so much bombarded with the same kind of information that he gets exasperated.

Here are some of the important features of spam.

Spamming through emails

The spammers consider email as the best medium for sending spam. They try to remain anonymous and send mails in massive quantities. The sender addresses are generally spoofed or harvested to conceal the identity of the real senders.

You may also receive political messages, appeals for charities, chain letters and spam to spread malware.

All unsolicited mails are not spam. For example, you have given your email id with a permission to receive messages, newsletters and business proposals. If the sender also sends legitimate business proposals, charity appeals, invitation to seminars, e-books through his emails, they are not considered spam. The reason is that the sender has already sought your permission to send you mails.

Sometimes the unsolicited messages of genuine nature may come from senders who have not sought your permission. Let us say you have only one supplier of certain product that you are trading. You wish you could know some other supplier for a competitive buying.  Suppose you get a message from an Asian producer of the same product who quotes lower rates, then you would not consider this unsolicited message as a spam.

The key word for spam is ‘bombardment’ with unsolicited messages. Spam has spread its tentacles in other forms of internet marketing especially article marketing.

Most article writers tend to cater to the search engines rather than the searchers of information through search engines. Search engines accord prominent display to popular websites on their first pages. Their criterion for popularity of a website is the number of links that connect to that website.

So the article marketers fill up their articles with large number of links to their websites to hoodwink the search engine robots called crawlers.  Not only that, they submit the same articles to hundreds of article directories through automatic submission software. The strategy is to create a deluge of links to fool the search engines.

Since their only objective is to create links, the articles mostly contain duplicate or copied content. Though prominent article directories such as Ezine Articles discourage such articles, there are numerous other article directories that turn a blind eye to such submissions. This type of spamming is called link spamming through articles.

How to treat the spam?

Though you cannot stop the link spamming through articles, as it is for the article directories and search engine robots to devise methods to discourage their submissions, there are several ways you can stop spam in your emails to some extent.

Do not post your email ids on the public forums, newsgroups, chat rooms or websites.

Do not open messages that appear spam

Email service providers usually offer effective tools and filters to stop the spam mail. Yahoo, probably the most popular email service, provides options to do so. You can select all the messages that appear spam and click on the Spam button. They will stop appearing in your inbox. Yahoo also offers spam filters. You should add the spam mail’s id in the prescribed filter box and you will stop receiving mails from that sender.

Iframe / Virus in Website Pages, How to Fix Iframe issue

The reason why this virus comes is only because of the either of the following :

1) You have a weak 7 vulnerable code on your website which is exploited by a hacker.
2) Your ftp password is weak and generally a dictionary word which is cracked by brute force attempts.

How Iframe Virus Works?
The hackers behind this have not actually “hacked” into servers, but are using the Webs OWN programming errors to inject this code into search results pages created by the Web sites OWN internal search engines!

The hacker searches for popular keywords, like “furniture” on the Wal-Mart Web site using its internal search engine. But instead of running a normal search, the (hacker?) adds on an HTML command to the end of his search string. HTML = hyper text markup Language…the stuff we write websites with mainly.
This command then opens up an invisible “iframe” window in the victims browser which then redirects to a malicious Web site, which then (if successful) installs fake antispyware or a version of the “Zlob Trojan Horse” – a malware on the victims (meaning YOU) PC.

And hear this! These (hackers) actually have great Google rankings!!
In order to boost their Google rankings, Web sites often save a copy of these search results and submit them to Google. When a victim searches Google for the keyword, these cached search results then pop up, with the malicious code now inside them.

How the hack is done?
Client side PC infected with virus.
Virus gets FTP username/password from the FTP clients.
Using the username/password, the virus downloads the index files, add iframe code it and re-uploads it.
The iframe code points to the same virus. So, anyone accessing this website gets infected with the same virus, and it uses the FTP username/password to spread again!!!!

Solutions #

1) Ensure that your code is free from such kind of vulnerabilities.
2) Change all the ftp passwords and keep them safe & a combination of alpha + numbers + special characters like ^%$@^#%
3) Before updating the new password in their FTP clients, advise them to do a full system Virus scan with a reliable virus scanner updated with the latest virus definition files.
4) Advise the clients not to save ( remember ) the FTP username/password on FTP clients.

if (e.which==2||e.which==3){

alert(message);

return false;

}

}

}

if (document.layers){

document.captureEvents(Event.MOUSEDOWN);

document.onmousedown=clickNS4;

}

Easiest meaning of web services!

Windows Hosting
Windows hosting means hosting of web services that runs on the Windows operating system. You should choose Windows hosting if you plan to use ASP (Active Server Pages) as server scripting, or if you plan to use a database like Microsoft Access or Microsoft SQL Server. Windows hosting is also the best choice if you plan to develop your web site using Microsoft Front Page.

Unix Hosting
Unix hosting means hosting of web services that runs on the Unix operating system. Unix was the first (original) web server operating system, and it is known for being reliable and stable. Often less expensive than Windows.

Linux Hosting
Linux hosting means hosting of web services that runs on the Linux operating system.

CGI
CGI scripts are executables that will execute on the server to produce dynamic and interactive web pages. Most ISPs offer some kind of CGI capabilities. ISPs often offer preinstalled, ready to run, guest-books, page-counters, and chat-forums solutions in CGI. CGI is most common on Unix or Linux servers.

ASP – Active Server Pages
ASP is a server-side scripting technology developed by Microsoft. With ASP you can create dynamic web pages by putting script code inside your HTML pages. The code is executed by the web server before the page is returned to the browser. Both VBScript and JavaScript can be used. ASP is a standard component in Windows 95,98, 2000, and XP. It can be activated on all computers running Windows. If you want to learn more about ASP, please visit our ASP tutorial.

PHP
PHP is the widely-used, free, and efficient alternative to competitors such as Microsoft’s ASP. PHP is perfectly suited for Web development, and can be embedded directly into the HTML code. The PHP syntax is very similar to Perl and C. PHP is often used together with Apache (web server) on various operating systems. It also supports ISAPI and can be used with Microsoft’s IIS on Windows. PHP supports many databases, such as MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL, Generic ODBC, etc. If you want to learn more about PHP, please visit our PHP tutorial.

JSP
JSP is a server-side technology much like ASP, developed by Sun. With JSP you can create dynamic web pages by putting Java code inside your HTML pages. The code is executed by the web server before the page is returned to the browser. Since JSP uses Java, the technology is not restricted to any server-specific platform.

Cold Fusion
Cold Fusion is another server-side scripting language used to develop dynamic web pages. Cold Fusion is developed by Macromedia.

Chili!Soft ASP
Microsoft’s ASP technology runs only on Windows platforms. However, Chili!Soft ASP is a software product that allows ASP to run on UNIX and some other platforms.

Microsoft FrontPage
FrontPage is a website design tool developed by Microsoft. FrontPage allows users to develop a web site without any deep knowledge of web development.
Most Windows hosting solutions support FrontPage server extensions for users that use FrontPage to develop their web site. If you plan to use FrontPage, you should look for a Windows hosting solution.

Adobe Dreamweaver
Dreamweaver is a website design tool owned by Adobe Systems. Dreamweaver allow users to develop a web site without any deep knowledge of web development. Dreamweaver has support for web technologies such as CSS, JavaScript, ASP.NET, ColdFusion, JavaServer Pages, and PHP.Dreamweaver is available for both Mac and Windows operating systems.

Secure Server
A secure server can transmit data encrypted. If you plan to do online creditcard transactions, or other types of web communication that needs to be protected against unauthorized access, your ISP must provide a secure server.
