Hacking has become a spine-chilling menace in the IT world and before we move on to steps to prevent the same we must know about the basics of hacking. The modification of the features of a system is part of what hacking is about. Via technical effort hackers cause manipulation of the standard behavior of a network and the systems which they are connected to. One reason why the cyber criminals hack websites is to have access to a server which is untraceable and what keeps the demand graph going high is the constant detection of hacks by website owners. Mailing out of spam’s through the mail servers of the websites is another reason for hacking.
Then and now
In the good old day’s emails were the whole sole agents from where malicious code was propagated but changing times have taken hacking to an all new level wherein websites are targeted to be the primal agents from where the dirty work is accomplished and the nasty code is distributed. Conventional wisdom may make users think that the plethora of adult or gambling websites floating the world wide web is the hub of such activities but the truth is farfetched from this since nowadays small business enterprises are the ones whose websites are abused the most, and the worst part being that the website owners themselves are unaware of their contribution. Even blogs or news sites are epicenters for nefarious hacker activity.
Modus operandi of hackers
Hackers may be able to enter websites via backdoors like URL querystrings and input forms like search, login or user input textboxes that has communication with a database. Bogus characters can be entered into the URL query strings which can be interpreted as an SQL and execution through an innocent database may result in breakdown of the website. This breakdown could cause error messages which may yield sensitive private information about the database. In this way they can have access to the structure of the database and maps or footprints of the columns’ and tables used in the website can be created. Having access over the database the hacker may erase sensitive information, cause virus infection or even steal sensitive data like credit card numbers. Websites which run by SQL databases are most hacker attack prone.
