Spam Collection and Detection System

As more users are connected to the Internet and conduct their daily activities electronically, computer users have become the target of an underground economy that infects hosts with malware or adware for �nancial gain. Unfortunately, even a single visit to an infected web site enables the attacker to detect vulnerabilities in the user’s applications and force the download a multitude of malware binaries. Frequently, this malware allows the adversary to gain full control of the compromised systems leading to the ex-�ltration of sensitive information or installation of utilities that facilitate remote control of the host. We believe that such behavior is similar to our traditional understanding of botnets. However, the main difference is that web-based malware infections are pull-based and that the resulting command feedback loop is looser. To characterize the nature of this rising thread, we identify the four prevalent mechanisms used to inject malicious content on popular web sites: web server security, user contributed content, advertising and third-party widgets. For each of these areas, we present examples of abuse found on the Internet. Our aim is to present the state of malware on the Web and emphasize the importance of this rising threat. Spamming is the most malicious task which allows the attackers to send the unwanted bulk messages to the users. Spam is flooding the internet with many copies of the same message in an attempt to force the message on people who would not otherwise choose to receive it. Most spam is commercial advertising, often for dubious products. Email spam targets individual users with direct mail messages. Email spam lists are often created by stealing Internet mailing lists, or searching the Web for addresses. Spam costs very little to the sender. Spam collection and detection system prevents in receiving spam messages. It protects email and web based messengers from receiving spam messages. It displays a notification if any spam mail or message received
