Phishing Attack
A phishing attack is a type of cyber scam where attackers try to trick people into giving away sensitive information, like passwords or credit card numbers. They usually do this by sending fake emails, messages, or creating fake websites that appear to be legitimate companies. For example, you may receive an email that looks like it's from your bank, asking you to click a link and log in, but the link will actually take you to a fake site designed to steal your credentials.
Phishing attacks rely on social engineering, meaning they play on human emotions like fear or urgency to get victims to act quickly without thinking carefully. To avoid falling victim to phishing scams, it's important to double-check email addresses, avoid clicking on suspicious links, and use multi-factor authentication wherever possible. It means to think carefully.
Malware Attack
A malware attack is when harmful software is used and designed to damage, disrupt, or secretly access a computer system without permission. "Malware" is short for "malicious software" and can take many forms, including viruses, worms, trojans, and spyware.
Once malware infects a device, it can steal sensitive data, monitor activity, and even disable the system. Malware is often spread through email attachments, infected websites or untrusted software. Using an antivirus program, keeping software updated and avoiding suspicious downloads can help protect against malware.
SQL Injection Attack
SQL injection (SQLi) is a type of cyber attack where attackers exploit vulnerabilities in a web application's database by inserting malicious SQL queries. This occurs when user input is not properly validated, allowing an attacker to manipulate the database. By doing so, they can gain unauthorized access to sensitive information such as usernames, passwords or even change or delete data.
Imagine a login form that directly searches a database using the information provided by the user. If not secured, an attacker could input malicious code instead of valid credentials, spoof databases to reveal personal information, or perform unintended actions. SQL injection is one of the most common and dangerous attacks, but it can be prevented with proper input validation, parameterized queries, and strong security practices.
DoS Attack
A Denial of Service (DoS) attack aims to make an online service, website, or network unavailable by overwhelming it with a flood of requests. In a DoS attack, hackers send a large amount of traffic to a target, causing its servers to slow down or crash, making it not accessible to authorized users.
Think of it like a crowd blocking the entrance to a shop so no one else can get in. These attacks can disrupt services, resulting in loss of revenue and productivity To prevent DoS attacks, organizations use techniques such as traffic filtering, load balancing, and firewalls.
Cross-Site Scripting (XSS) Attack
A Cross-Site Scripting (XSS) attack happens when hackers inject malicious scripts into web pages that other users visit. These scripts can control personal data such as cookies, session tokens or even the user's browser.
For example, if a website doesn’t properly check user inputs, an attacker might insert a harmful script into a comment section and when another visitor views the page, their browser executes the script. XSS attacks can be prevented by sanitizing user input and using safe coding practices.
Ransomware Attack
A ransomware attack is when cybercriminals infect a system with malicious software that locks users out of their own files or devices. The attacker then demands a ransom, often in cryptocurrency, to unlock the data.
Ransomware can spread through phishing emails, compromised websites or software vulnerabilities. Once infected, victims usually see a message demanding payment to restore access to their files. Backing up data regularly and using security software are important steps to protect against ransomware.
Man-in-the-Middle (MiTM) Attack
A Man-in-the-Middle (MiTM) attack happens when a hacker secretly intercepts and alters communication between two parties without them knowing. It's like someone overheard your conversation and is probably exchanging messages without either party realizing it.
This can happen on unsecured networks like public Wi-Fi, where attackers can steal sensitive information like passwords, credit card details or private messages. To protect against MiTM attacks, it is essential to use secure connections (like HTTPS) and encryption.
Cryptojacking Attack
A Cryptojacking attack occurs when hackers secretly use someone else's computer or device to mine cryptocurrency without their knowledge or consent. They do this by injecting malicious code into websites or software, allowing them to hijack the device's processing power to generate digital coins.
This can slow down the device, increase electricity bills and cause overheating. Cryptojacking is particularly stealthy because victims often don't realize their devices are being used for this purpose. Protecting against cryptojacking involves using security software, updating systems, and being careful about what you click.
Insider Threat attack
An Insider Threat attack happens when someone within an organization, like an employee, contractor, or business partner, uses their access to harm the company. This may involve stealing sensitive information, leaking confidential information or hacking systems.
Since insiders already have trusted access, these attacks can be difficult to detect and often cause significant damage. Insider threats can occur intentionally (such as retaliation or financial gain) or unintentionally (due to negligence or mistakes). To prevent these attacks, organizations use strict access controls, monitor activity, and provide security training to employees.
Zero-Day Exploit Attack
A Zero-Day Exploit attack happens when hackers take advantage of a software vulnerability that the software's developers or users don’t know about yet. The term "zero-day" means the developers have had zero days to fix the flaw before it can be exploited by attackers.
Since there are no fixes or patches available at the time of attack, these vulnerabilities are extremely dangerous and can be used to steal data, spread malware, or cause damage. Regular software updates and security practices can help reduce the risk of these attacks.
