Takeaways

• 😀 Cybersecurity threats are attacks aimed at unauthorized access to digital devices, systems, and data.
• 😀 59% of the global population uses the internet, making it crucial to protect electronic devices from cyber threats.
• 😀 Phishing attacks involve impersonating trusted entities to steal personal information like login credentials and card details.
• 😀 Ransomware forces users to pay a ransom in exchange for access to their encrypted data, but payment may not guarantee data recovery.
• 😀 Malware is malicious software created by hackers to damage, steal, or gain unauthorized access to systems and networks.
• 😀 A Man-in-the-Middle (MITM) attack occurs when hackers intercept and manipulate communications between users and servers.
• 😀 Trojan horses are disguised malware programs that deceive users into installing them, allowing unauthorized access to sensitive data.
• 😀 SQL injection attacks manipulate database queries to access confidential information without permission.
• 😀 DoS and DDoS attacks overwhelm websites with fake requests, causing them to crash and disrupt service.
• 😀 Best practices to prevent cyber threats include keeping data private, using strong passwords, updating antivirus software, and scanning emails for malware.
• 😀 Regularly checking privacy settings, ensuring secure website URLs (HTTPS), logging out after use, and respecting others' privacy are key methods to avoid cyber attacks.

Q & A

What are cybersecurity threats?

Cybersecurity threats are offensive actions taken by hackers or unauthorized individuals to exploit vulnerabilities in electronic devices, systems, or networks. These threats aim to steal, damage, or alter sensitive data and information.

How has the rise of internet usage impacted cybersecurity?

With 59% of the global population now connected to the internet, electronic devices are at a higher risk of being targeted by cybercriminals. This makes it increasingly important to implement robust cybersecurity practices to protect sensitive data.

What is phishing and how does it work?

Phishing is a cyberattack where hackers impersonate trusted entities to gain access to personal information such as login credentials and financial details. This is commonly executed through fraudulent emails, phone calls, or messages.

What is ransomware and how does it affect users?

Ransomware is a type of attack where a hacker encrypts or locks a victim's data and demands a ransom to restore access. A famous example is the 2017 WannaCry attack, which exploited a flaw in the Windows operating system.

What is malware and how does it pose a threat?

Malware, short for malicious software, is a program created by hackers to infect, steal, or gain unauthorized access to systems and networks. It is a dangerous type of attack that can cause significant damage to devices and data.

Can you explain a Man-in-the-Middle (MitM) attack?

A Man-in-the-Middle attack occurs when a hacker intercepts communication between two parties, such as a client and server. This allows the hacker to misinform or steal data from both sides without their knowledge.

What is a Trojan Horse cyberattack?

A Trojan Horse is a type of malware disguised as legitimate software. Once executed, it gives hackers unauthorized access to sensitive information, including personal credentials and financial details.

What is SQL injection and how does it work?

SQL injection is a cyberattack where malicious data is inserted into an application’s database to give hackers unauthorized access to confidential information. It targets vulnerabilities in the system’s SQL queries.

What are DoS and DDoS attacks, and how do they disrupt websites?

DoS (Denial of Service) and DDoS (Distributed Denial of Service) attacks overwhelm a website with fake requests to cause it to crash. A DDoS attack uses a network of compromised devices, known as botnets, to flood the server with traffic.

What are the best practices to avoid cybersecurity threats?

Best practices include keeping your data private, using strong passwords, updating antivirus software, scanning emails before opening, checking privacy settings, verifying website URLs, logging out of systems after use, and respecting others' privacy.
