Malware is an inner software created to destroy computers and some other smart devices. There are so many forms of malware and they are: Trojan, spyware, ransomware, viruses, adware, and worms
How do I detect and respond to malware?
Malware will eventually get into systems and network but there must be a security system that notifies when the security of the system and network have been breached. It is important to know the source of the attack so as to effectively manage its impact. Antivirus software alone can secure a system and network against advanced malware attacks.
Types of malware
Viruses are a type of malware designed as malicious software and then attached as a document to emails and other forms of communication with the intention of causing damage. Viruses lay silently until the infected file is downloaded on the system and put to use.
Worms are a form of malware that duplicates itself and spread to all the part of the system and network. Worms can infect a system through a network connection or a downloaded file even without a host.
A trojan is created to look for a software program meant to solve a particular problem. It gains access to the file of the user once it is downloaded on the system. It can edit, delete and block all the data found on the attacked system. Trojan viruses do not duplicate itself.
Spyware is another type of malware that works hiddenly on a system and gives a report of the activities to the spy. Spyware identifies all important information and gives the attacker access to this information. It is used to steal personal information such as passwords and account information.
This is malicious software that is employed to take data from a computer and it advertises products suitable to the user without the consent of the user. Although adware is not harmful it can cause so many issues and disruption to the user of the system when it redirects users to websites that are very harmful.
Ransomware is malicious software that gives cybercriminals access to sensitive information on the system and then demands compensation before decrypting the data on the system. The attacker releases the key to the encrypted data is held hostage.
Fileless malware is a type of malware that lives in the memory of the system. It can be very difficult to detect because the malware hides as soon as the system is rebooted which makes forensic almost impossible to do.
