Study Notes
Hacking
- Most hacking attacks utilize public Wi-Fi to stay anonymous.
- Hackers exploit the ease of accessing public Wi-Fi networks to gain unauthorized access to data.
- Public Wi-Fi networks are often unsecured, making it easy for hackers to steal information.
Basic Terminology
- Hackers are categorized into white, gray, and black hat types.
- Denial-of-Service (DoS) attacks overwhelm a server with requests, making it inaccessible.
- Distributed Denial-of-Service (DDoS) attacks originate from multiple sources, making them harder to defend against.
- DDoS attacks require multiple devices/connections to flood a specific target server, making them harder to prevent as compared to DoS attacks. To launch a DDoS attack, perpetrators need sophisticated tools & preparation, and multiple infected devices for making simultaneous attacking requests to a given server.
- Tools like RATs (Remote Administration Tools) are used for controlling infected devices for launching attacks
Phishing Attacks
- Phishing involves creating fake websites and emails that mimic legitimate ones.
- Victims are tricked into entering their login credentials, providing hackers with sensitive data.
- The phishing attack is often used to target sensitive/personal information, including credentials & money transfers.
SQL Injections
- SQL injection attacks target vulnerabilities in web applications to execute malicious SQL commands.
- This technique enables hackers to gain access to an organization's databases.
- This method is also often used for targeting sensitive information through vulnerabilities like data breaching.
Virtual Private Networks (VPNs)
- VPNs create a secure connection to conceal a user's IP address.
- VPNs encrypt data to ensure privacy and security when surfing the internet.
Proxies
- Proxies act as intermediaries to mask a user's IP address.
- They offer a level of anonymity, though not impenetrable.
- Using a proxy can make it harder to track users online.
Tor
- Tor is a free and open-source network that hides a user's location.
- Tor users' IP addresses are difficult to trace, which protects their anonymity.
VPS (Virtual Private Servers) and Keyloggers
- Virtual Private Servers (VPS) can be used to create a secure layer for sensitive online tasks or for accessing confidential data.
- Keyloggers can be used to extract login credentials and other sensitive information.
- Keyloggers are used by hackers to steal personal information and login details from various online sources/accounts.
Precautions
- Be cautious about where you download tools.
- Never download uncompiled binaries.
- Never run suspicious tools or programs on your computer.
- Always use verified tools.
- Use virtual machines for testing suspicious tools.
