Malware

Malware refers to a wide range of malicious software, including viruses and ransomware. Once malware is installed on your computer, it can cause a wide range of problems, including gaining control of your system, monitoring your actions and keystrokes, and covertly transferring sensitive data from your computer or network to the attacker’s home base.

Phishing

An attacker may send you an email that looks to be from someone you know and trust, such as your boss or a company you do business with, in a phishing assault. The email will appear to be real, and it will contain a sense of urgency (e.g. fraudulent activity has been detected on your account). There will be an attachment to open or a link to click in the email.

When you open the fraudulent attachment, malware is installed on your machine. If you click the link, you may be taken to a legitimate-looking website that asks you to check in to view a critical file—except that the website is actually a trap designed to steal your credentials when you try to log in.

SQL Injection Attack

An SQL injection attack works by exploiting any of the known SQL vulnerabilities, allowing malicious code to run on the SQL server. For example, if a SQL server is vulnerable to an injection attack, an attacker may be able to enter code into a website’s search box that causes the site’s SQL server to spill all of the site’s stored usernames and passwords.

Denial-of-Service (DoS)

A denial-of-service (DoS) attack essentially does the same thing to a website. If you flood a website with more traffic than it was designed to manage, the server will become overburdened, making it nearly difficult for the website to serve its content to users.

Session Hijacking and Man-in-the-Middle Attacks

When you use the internet, your computer conducts several small back-and-forth transactions with servers all over the world, informing them of your identity and requesting specific websites or services. If everything goes according to plan, the web servers should respond to your request by providing you with the information you requested. This procedure, often known as a session, happens whether you are simply browsing or when you are logging into a website with your username and password.

An attacker can hijack a session by capturing the session ID and acting as the machine making a request, allowing them to log in as an unsuspecting user and get access to unauthorized information on the webserver.
