Takeaways

• 😀 Phishing is a tactic where hackers trick individuals into revealing personal information by pretending to be trusted sources like banks or social media sites.
• 😀 Spear phishing targets specific individuals or companies with personalized messages to increase their chances of success.
• 😀 Whaling focuses on high-profile individuals such as CEOs and executives, crafting highly targeted attacks to steal sensitive information.
• 😀 Malware is harmful software designed to damage computers or steal data, including viruses, Trojans, and ransomware.
• 😀 Ransomware locks up your files or system and demands payment for their release, essentially holding data hostage.
• 😀 Spyware secretly monitors your activities on your computer, including keystrokes, screenshots, and even activating your webcam without permission.
• 😀 A Trojan Horse is a seemingly harmless program that hides harmful malware, taking over your system once installed.
• 😀 Worms are self-replicating programs that spread across networks without user intervention, causing widespread damage.
• 😀 SQL injection allows hackers to insert malicious code into a website's database, enabling them to steal, alter, or delete data.
• 😀 Brute Force attacks involve hackers guessing passwords through every possible combination until they gain access.
• 😀 Social engineering manipulates people into giving away personal information or performing actions that they wouldn't otherwise do, often by creating a sense of urgency.
• 😀 Keyloggers track everything you type on your keyboard, including passwords and sensitive information, without your knowledge.
• 😀 Session hijacking allows hackers to take over a user's session after they've logged into a secure system, gaining unauthorized access to their data.
• 😀 DNS spoofing tricks your computer into visiting a fake website, making it look like you're on a legitimate site when you're not.
• 😀 Clickjacking hides malicious actions under legitimate website buttons or links, leading you to perform unintended harmful actions.
• 😀 Rogue software masquerades as helpful programs, such as fake antivirus, but in reality, it damages your system or steals data.
• 😀 Drive-by downloads occur when visiting a compromised website, which automatically downloads harmful software onto your device.
• 😀 Rootkits are hidden programs that give hackers control over your computer while remaining undetected by antivirus software.
• 😀 Botnets are networks of infected computers controlled by hackers to launch large-scale attacks or send spam emails.
• 😀 Password spraying involves trying a few common passwords across multiple accounts, instead of testing multiple passwords on one account.
• 😀 Cryptojacking secretly uses your computer's resources to mine cryptocurrency, often without the user's knowledge.

Q & A

What is phishing and how does it work?

Phishing is when hackers deceive individuals into providing their personal information by pretending to be someone they trust, such as their bank or a social media site. They often send fake emails or messages that look real but are not.

How is spear phishing different from phishing?

Spear phishing is a more targeted form of phishing. Instead of sending out generic messages, hackers focus on specific individuals or companies, often with prior knowledge about the target to make the attack more convincing.

What does whaling refer to in cyberattacks?

Whaling is a type of phishing aimed at high-profile individuals, such as CEOs or executives. Hackers craft highly personalized messages to trick these individuals into revealing sensitive information.

What is ransomware and how does it work?

Ransomware is a type of malware that locks a victim's files or system and demands money to unlock them. It is similar to a digital kidnapping, where hackers hold your data hostage until a ransom is paid.

What is spyware and how can it affect you?

Spyware is malicious software that secretly monitors your activities on your computer, including tracking keystrokes, capturing screenshots, or even turning on your webcam without your knowledge.

What is a Trojan Horse in the context of cybersecurity?

A Trojan Horse is malicious software that appears useful or harmless but contains harmful code. Once installed, the hidden malware can take control of the victim's computer.

What is an SQL injection attack?

SQL injection is an attack where hackers insert malicious code into a website's database. This can allow them to steal, alter, or delete data from the site, acting like a backdoor into a secure system.

What is the purpose of a Denial of Service (DoS) attack?

A DoS attack floods a website or network with excessive traffic, causing it to crash and stop working. A Distributed Denial of Service (DDoS) attack is a larger-scale version where multiple systems are used to overwhelm the target.

What is a Man-in-the-Middle (MITM) attack?

In a Man-in-the-Middle attack, hackers secretly intercept and alter communication between two parties. This allows them to steal or modify the information being exchanged, like eavesdropping on a phone call and changing what is being said.

What does credential stuffing involve?

Credential stuffing is when hackers use stolen usernames and passwords from one website to attempt to log into other sites. They hope that individuals reuse the same password across multiple platforms.
