These types of cyber security threats are made by cybercriminals who set up fake public Wi-Fi networks or install malware on victims’ computer or networks. Not every network attack is performed by someone outside an organization. When calculating the probable cost of SQLI, you need to consider the loss of customer trust in case personal information like addresses, credit card details, and phone numbers are stolen. Spyware is a form of malware used to illicitly monitor a user’s computer activity and harvest personal information. Malware differs from other software in that it can spread across a network, cause changes and damage, remain undetectable, and be persistent in the infected system. It is a slower and less glamorous process. A SQL (Structured Query Language) injection occurs when an attacker inserts malicious code into a server that uses SQL. Phishing is often used to obtain a foothold in governmental or corporate networks as part of a more significant plot such as an advanced persistent threat (APT). Hardware vulnerabilities are exploitable weaknesses in computer hardware. Any device within the transmitting and receiving network is a vulnerability point, including the terminal and initial devices themselves. A threat is a threat which endangers a system or a practice. Brute force attacks reiterate the importance of password best practices, especially on critical resources such as network switches,  routers, and servers. There are several types of cyber threats, as well as varying motives of the attackers. The attack occurs between two legitimate communicating parties, enabling the attacker to intercept communication they should otherwise not be able to access. It can destroy a network and bring a machine’s performance to its knees. Phishing 5. If you have a system’s credentials, your life is even simplified since attackers don’t have these luxuries.
