With the increasing use of technology and computer applications, cases of cybercrime have raised and many people have and others are still falling onto the wrong side of cyber criminals. Most common cybercrimes include cyber extortion, forgery, phishing, cyber terrorism, and online harassments among many others (Al-Alawi, 2014). In order to tackle this rising threat, there was a need to develop a mechanism powerful enough to stop and secure victims before or even after the damage occurs; computer forensics. Computer forensics is a law enforcement field powerful when it comes to combating cybercrimes (Technology First, 2018).
Of all the cybercrimes existing, phishing tends to be the most crucial since it accesses private information such as passwords as well as usernames and details entailed on the credit cards. Cyber criminals do this by disguising themselves as trusted entities (Digital Forensics, n.d). Phishing can be done through emails to the targeted individuals posing as banks or major and highly established institutions or sites. The procedures used in discovering and investigating the evidence of phishing starts the moment computer forensics specialists are informed. The procedures applied in securing the evidence usually require specific techniques as well as tools. Computers and email systems often have a number of software and hardware components, including the server computers and sender’s client as well as the server computer and the receiver’s client having different services and software installed (Banday, 2011).

In addition, the use of various internet services and systems are highly appreciated. As much as the information can be deleted from a computer system, it may not be deleted from the server thus an entry point for the computer forensic technicians. Computer forensics usually involves the utilization of specialized software for the purposes of making “an image of a subject system's” physical memory and hard drive and to parse automatically into formats which are human-recognizable (Francis, 2017). Technology has greatly aided in the rapid search as well as evidence analysis across the computer and network system. Foundation of endpoint detection and response (EDR) is greatly used as it packs a number of capabilities, making forensics work easier (Francis, 2017). Different software’s may be used in investigating phishing and preventing it such as the Mimecast. Mimecast phishing software provides at least three protective layers to protect the people and defend them from the growing phishing danger and other related advanced attacks (Mimecast, 2018).
As the world of technology keeps on growing and expanding dangers in relation to it, cybercrimes which entail cyber extortion, forgery, phishing, cyber terrorism, and online harassments among many others keep rising as well. In order to combat and curb the rising threat of cybercrime then there is a need to develop computer forensics, a perfect tool for dealing with cybercrime.
