Don’t install suspicious third party programs because this could be a gateway to allow hackers to mess with your operation system. In addition, avoid opening unknown and suspicious emails as they can execute malicious programs or malware that can lead to your PC becoming a zombie bot. Make updates as soon as possible when your antivirus and firewall programs ask your permission.

Therefore, if you don’t have a firewall and an antivirus software, we strongly advise to install them at once.

Run malicious programs through the excess data.īuffer Overflow comes in many sizes and these days, they can come also as viruses.

Corrupt data that was stored in other buffers, which may lead to a 404 error.

How Does Buffer Overflow Affect You?Īccording to the SANS Institute, a buffer overflow may cause havoc on network systems and applications. However, malicious hackers are able to enact an overflow and perform severe damage to any computing system. The overflow of data can be caused by a simple programming error made during its development. Buffers have a limited amount of data they can store and if the buffer is overwhelmed with extra data, it will naturally fall into adjacent buffers to make up the storage. Buffer overflow happens in a very similar, albeit a bit more complicated way. If there is more water than it can hold, the water will leak and overflow onto your table. It has the capacity to store a fixed amount of water or, in this case, data.

Now, imagine a buffer as an empty cup that can be filled with water or ice. The computer assigns this data to a temporary storage, also known as a “buffer”, where they can be quickly used and deployed. This data could originate from data associated with the program or logged data that is stored on your computer. To put it simply, most programs that run in our computers manipulate data of some form. In a buffer overflow attack, a hacker most commonly manipulates the application’s memory or exploits.

A buffer overflow is one of the most known forms of software vulnerabilities. Data can exceed a buffer’s capacity. Not many people may know or have heard about buffer overflow, but we are here to help you understand this dangerous web threat. Buffer overflow attack is a cyberattack method in which the attacker exploits an application’s security by deliberately overwriting the application’s memory.
