This element receives packets of data and sends that data out to all of the connected ports. Because a DoS attack can be launched from nearly any location, finding thoseresponsible for them can be difficult. Others are installed by exploiting a known vulnerability in an operating system (OS), network device, or other software, such as a hole in a browser that only requires users to visit a website to infect their computers. These occur when the attacked system is overwhelmed by large amounts of trafficthat the server is unable to handle. Logs show a strong and consistent spike in bandwidth. DoS attacks are used to shut down individual machines and networks so that they cant be used by other users. Popular languages for malicious mobile code include Java, ActiveX, JavaScript, and VBScript.

While some simple ransomware may lock the system in a way that is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral extortion, which encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. Victims of DoS attacks often target web servers of high-profile organizations such as banking, commerce, and media companies, or government and trade organizations. Flood attacks occur when the system receives too much traffic for the server to buffer, causing them to slow down and eventually stop.
