A cyber criminal sends a series of maliciously formatted packets to the database server. The server cannot parse the packets and the event causes the server crash. What is the type of attack the cyber criminal launches?

DoS attack

Explanation:

A Denial of Service attack involves the sending of maliciously formatted data packets to a server. The packet can be larger than the allowed IP size such that when it arrives at the server, the server cannot identify the headers in the data packet for it to process and extract data. The server can either freeze or crash, denying allowed users access to its resources and making it unavailable.
