Software supply chains are particularly vulnerable because modern software is not written from scratch: rather, it involves many off-the-shelf components, such as third-party APIs, open source code and proprietary code from software vendors. Cybersecurity is the method of safeguarding networks, computer systems, and their components from unauthorized digital access. Ransomware attacks are usually launched through malicious links delivered via phishing emails, but unpatched vulnerabilities and policy misconfigurations are used as well. Once inside the system, malware can do the following: Phishing is the practice of sending fraudulent communications that appear to come from a reputable source, usually through email. Any website that is database-driven -- and that is the majority of websites -- is susceptible to SQL injection attacks. Man-in-the-middle (MitM) attacks, also known as eavesdropping attacks, occur when attackers insert themselves into a two-party transaction. Usually, the attacker seeks some type of benefit from disrupting the victims network. Below are some of the most common types of cyber-attacks: Malware Phishing Man-in-the-middle attack (MITM) Distributed Denial-of-Service (DDoS) attack SQL injection Zero-day exploit DNS Tunnelling Business Email Compromise (BEC) Cryptojacking Drive-by Attack Cross-site scripting (XSS) attacks Password Attack Eavesdropping attacks AI-Powered Attacks In a keylogger attack, the keylogger software records every keystroke on the victims device and sends it to the attacker.

According to the Cisco Annual Cybersecurity Report, the total volume of events has increased almost fourfold between January 2016 and October 2017. Software supply chain attacks inject malicious code into an application in order to infect all users of an app, while hardware supply chain attacks compromise physical components for the same purpose. Typically, a user will see scareware as a pop-up warning them that their system is infected. Smishing is the act of sending fraudulent text messages designed to trick individuals into sharing sensitive data such as passwords, usernames and credit card numbers. End-to-end encryption throughout a network stops many attacks from being able to successfully extract valuable data even if they manage to breach perimeter defenses. private data, like cookies or other session information, to the The goal is to steal sensitive data like credit card and login information or to install malware on the victims machine. A brute force attack is uses a trial-and-error approach to systematically guess login info, credentials, and encryption keys.
