In order to understand what cookie threats are, first of all, we need to understand what cookies are!
1. What Are Cookies?
2. How Can a Cookie Harm my Computer?
A cookie itself cannot harm the computer, as it does not and cannot hold code (therefore the cookie cannot perform an action itself). However, the cookie can support (help) malicious actions to be taken on the respective system. Even more, being a plain text file, they are vulnerable, meaning that they can be “harvested” by other applications.
3. Why Should I Scan the Cookies?
As already mentioned the cookies themselves cannot harm the computer. However, they can contain certain information to lead a possible attacker to the respective computer. For example, we will consider that an attacker releases a Trojan in the wild in order to gain control over several computers. This Trojan’s payload contains dropping a Backdoor (to open a port), changing the homepage of the browser, and placing a “malicious” cookie in the browser’s cookie area. When the unsuspecting user launches the browser, then it automatically connects to the new homepage (namely the attacker’s website).
Once this is done, the malicious cookie is being read and the attacker becomes aware of the fact that the computer is infected. By knowing this, it becomes a piece of cake to take over the computer using some exploits or the open port.
Let’s say that the user becomes aware of the infection and manages to remove the Trojan and the Backdoor from the computer. However, if the cookie remains on the computer, it can supply the information again to the attacker if the user “manages” to access the untrusted web page again. The computer is therefore exposed once again to a possible attack.
As explained in the above scenario, the cookie is used to provide information about a computer but it is not responsible for the attack itself.
4. Other Types of Malicious Attacks Using Cookies?
5. Are Cookies a Threat for our Privacy?
Cookies are of two types that stored in the system. Session cookies and Persistent cookies. The session cookies don’t have the retention ability after closing the browser and it is stored in temporary memory. When it comes to persistent cookies then it collects the statistical data of the website and user activity. Also, it is used for the provision of customized content. But these cookies create fewer privacy concerns than third-party cookies. It is the main type of cookies that create privacy concerns for users.
When talking about cookies it’s important to know how to protect cookies from other cookies or applications or how to protect a computer against cookie attacks. Due to the fact that internet cookies are necessary for browsing or the fact that the cookie traffic is invisible to the computer user, a “cookie control” module is needed to help the user. That’s why, you need to have good internet security on your computer, which can detect both virus and spyware attacks.
