Cyber Threats: What is Malware?

Malware or otherwise Malicious software is a file or code that can typically when delivered cause damage to a system or resource. Malicious coders can write code that can cause harm or infect a system. This program can be used for almost anything, stealing sensitive information, spying on user behavior, or denying access.

Types of malware

Viruses – A virus can be any program that copies itself throughout a computer or network. Viruses can attach themselves to friendly programs and can be activated by an unsuspecting user by opening a file. Once infected, a virus can corrupt, delete or steal data from a system. New viruses are being created every day and antivirus signatures do not always detect them.

Worms – A worm is a form of a virus that self-replicates through systems by using a security vulnerability. Unlike viruses, worms can spread without attaching to files and can infect several systems on a network before being discovered.

Trojans – Unlike viruses and worms, trojans can be easily hidden in a common file type, and once activated cause serious damage to a system. A trojan disguises itself as a harmless file, like the story of the Greek soldiers hidden within a wooden horse. This is how it received its name.

Rootkits – Rootkits can be a very serious concern. They can be written into systems before you ever receive them. They generally operate at a root level and have administrative privileges to your systems. Rootkits are very difficult to detect because they are implanted by coders within programs that we receive.

What can be done to stop Malware?

Antivirus software, with regular updates, can be an effective tool to stop malware. Most leading vendors publish signature updates frequently to detect recent malware. With phishing and social engineering being a primary attack vector, education and strong email security are necessary to prevent malware from getting on a network. Additionally, having endpoint security information event management (SIEM) technology on a network can also provide real-time security to administrators.
