The digital world is fraught with various cyber threats that can compromise your data, privacy, and financial security. Understanding these common threats is the first step toward protecting yourself and your business.
1. Malware (Malicious Software)
Malware is a broad term for any software designed to harm or exploit computer systems. It includes:
- Viruses: Attach to legitimate programs and spread when those programs are executed.
- Worms: Self-replicating malware that spreads across networks.
- Trojans: Disguise themselves as legitimate software but carry out malicious activities in the background.
- Spyware: Secretly monitors and collects information about your computer activity.
- Adware: Displays unwanted advertisements.
2. Phishing
Phishing is a social engineering tactic where attackers attempt to trick individuals into revealing sensitive information (like usernames, passwords, and credit card details) by impersonating a trustworthy entity in electronic communications (e.g., email, text messages).
3. Ransomware
Ransomware is a type of malware that encrypts a victim's files, making them inaccessible. The attacker then demands a ransom payment (usually in cryptocurrency) in exchange for the decryption key. Failure to pay often results in permanent data loss.
4. Man-in-the-Middle (MitM) Attacks
In a MitM attack, an attacker intercepts communication between two parties, often without their knowledge. This allows the attacker to eavesdrop, steal data, or even alter the communication. Public Wi-Fi networks are particularly vulnerable to MitM attacks.
5. SQL Injection
SQL injection is a code injection technique used to attack data-driven applications, in which malicious SQL statements are inserted into an entry field for execution (e.g., to dump database contents to the attacker).
6. Cross-Site Scripting (XSS)
XSS attacks involve injecting malicious scripts into otherwise benign and trusted websites. When a user visits the compromised site, the malicious script executes in their browser, potentially stealing cookies, session tokens, or other sensitive information.
