Cyberattack is any wrongful activity performed with an aim to alter the functioning or gain unauthorized information from computer networks, computer information systems or personal computer devices. To try and gain unauthorized entry into a computer system, a cyber-attack hacker can try either of the following procedures; denial of services(DOS), malware, phishing, session hijacking, structured query language, and cross-site scripting
For a phishing attack to take place, a dubious email attachment is sent to a computer system and upon opening it a malware is automatically installed into the computer altering the normal performance of the targeted computer. To allow for immediate click on a malicious link sent, an attacker creates a link that is likely to entice the user to click on it as it could create some sense of urgency, confusion or quick gratification which may be in form of a monetary promise.
Spear attacks, pharming, clone phishing, whaling are some of the forms in which phishing can be executed.Whaling attacks are usually focused on high profile targets with the aim of capturing company’s data, company’s intellectual property and personal credential that can be used to blackmail or even sold at black market. Cloning attacks happens when a user receives a clone of a valid message they had received earlier but there is a bit of change made to it by the attacker to trap the user. By getting details such as a company’s email address and website, the company’s logo, an attacker is able to craft an email that looks real to the specific target who happens to be the high profile workers in a company and once clicked a malware is installed therefore altering the normal function of a computer.
To protect hacking into an email a user needs to apply the following; use of strong passwords, spam filters, changing the passwords frequently and use of certified antivirus. A spam filter is a program that detects false emails and ensures that they do not find their way to a user’s inbox. Computer viruses and spam can be stopped from getting into a user’s inbox by email filtering which is the organizing of emails. To help with email filtering, inbound or outbound filtering can be used.
Inbound filtering is where messages from the internet are scanned by the filtering system. Before a message can be delivered to other users over the internet by a local user, outbound filtering is performed. In ensuring that workers observe the code of conduct for email, mail filters can be used and keep a check on the outgoing emails.
