Keywords
💡cybercrime
Cybercrime refers to criminal activities carried out through the internet or other computer systems. It is a significant issue that impacts society on personal, financial, and national security levels. In the video, it is mentioned that cybercrime has resulted in the theft of credit card numbers, Social Security numbers, healthcare records, and even attacks on critical infrastructure like nuclear centrifuges and drones.
💡vulnerabilities
Vulnerabilities are weaknesses in hardware or software that can be exploited by cybercriminals to gain unauthorized access or perform malicious actions. The video discusses how cybercriminals often take advantage of these vulnerabilities or human errors to commit crimes, emphasizing the importance of security measures to protect against such threats.
💡cyber army
A cyber army is a group of individuals or a coordinated effort by a nation-state to engage in cyber warfare or cyber espionage. The video suggests that in addition to traditional military forces, countries now maintain a cyber army to defend against or initiate attacks in cyberspace, highlighting the strategic importance of cyber capabilities in modern warfare.
💡computer virus
A computer virus is a type of malicious software that, once installed on a computer, can cause harm by stealing, deleting files, or taking control of the system. The video explains that viruses can spread from one computer to another, often through deceptive means such as disguised security updates, and can be used to create a botnet for launching attacks like distributed denial of service (DDoS).
💡distributed denial of service (DDoS)
A DDoS attack is a malicious attempt to disrupt the normal functioning of a website or a network by overwhelming it with a flood of internet traffic. The video describes how hackers use a botnet of infected computers to generate billions or trillions of requests, causing the target website to become overloaded and cease responding to legitimate users.
💡phishing scam
Phishing is a type of online scam where criminals send seemingly trustworthy emails to trick recipients into revealing sensitive information, such as login credentials. The video provides an example of how a phishing scam might involve an email directing users to a fake website that looks legitimate, but is actually designed to steal their passwords.
💡spam email
Spam email refers to unsolicited messages sent in bulk, often with the intent to advertise products, spread malware, or conduct phishing attacks. In the context of the video, spam emails are used by cybercriminals to attempt to deceive people into sharing personal information, which can then be exploited for fraudulent purposes.
