Before malware can do anything, it first has to find a way onto the system. One way to do this is by gaining administrative rights. If someone has gained access to important passwords or accounts via phishing or other malware on another system, they can then install more malware on the new system. The next form of access is social engineering. What social engineering boils down to is tricking the end user into executing the malicious code. If the user can be tricked into installing what they thought was a useful program, the malware can enter the system and execute its duties. The final and most popular form of access is exploiting an existing vulnerability. This is done when there is a bug that has been overlooked by a software developer. When this vulnerability is spotted, malware can be made to exploit the bug and infiltrate the desired system.
