The problem of virus and hackers is never ending. The best way to protect your PC is by upgrading it with better security and antivirus programs on regular basis. Talking about the exploitation of usual vulnerabilities by hackers in some applications, you will be shocked to see that even the big companies and government department get hacked. These hackers have a good knowledge on which point should be targeted to break the site. Usually, the attackers get the basic details about the system that needs to be targeted. It focuses on the important details like on which OS does it runs or is there any kind of firewall that protects the OS. Is there any port available? Usually, the attacker gathers most of this information from the social media services like Twitter and Facebook.

SQL Injection:

In this type of attack, the database gets manipulated which is usually sent by the web application. At times, an application can turn to be vulnerable if the right protection is not used. Sometimes it also becomes easy for the attacker to target this application if the parameter value is used without the proper validation process in the database queries. As per the research made in the year 2010, it has been concluded that nearly 14% of the breaches had included the injection of SQL for which the process took pretty much time to get rid of it. The best way to protect this application is to ensure that parameterized SQL is used and libraries are well tested and code reviewed.

Phishing:

It is another common exploitation of usual vulnerabilities by hackers that has been around for quite a long time in some of the applications. The technique is not that difficult. It includes a spam email to be sent to the recipients. Once the user clicks on the link which takes to a malicious site, then the user’s credentials in the login form are captured by the site. If any of the emails that you get says that your passwords need to be reset or the link is being sent to reset the [password, then do not attempt to click on it. Sometimes the email that you get from the people is also hacked. Do not take the risk to click on such email that contains links from people you know.

Taking a right care against the problem:

Other than this malware attacks, spear phishing, weak authentication is some of the usual tricks which a hacker usually uses in some applications. The details about most of the vulnerabilities that have been found in the different applications have already been noted down. Usually, a hacker can successfully attack the applications that are misconfigured or the networks are not properly closed. That is the main reason why you need to always keep the track of different vulnerabilities.
