What Are the Most Common Types of Cyber Attacks?

Introduction

Cyber attacks cost $10.5 trillion globally in 2025. Phishing leads at 36%, followed by ransomware at 24%. Every 39 seconds, a business faces an attack. Understanding common threats is the first step to defense. Ethical Hacking Training Institute teaches all attack types in CEH labs with real tools. Webasha Technologies and Cybersecurity Training Institute offer 100% placement after mastering attacks and defenses. This guide covers the top 10 cyber attacks, how they work, real examples, and prevention. No jargon, just facts. Learn to think like a hacker and protect like a pro. Start with phishing and build knowledge. Your security journey begins here. Explore the cybersecurity career path.

Phishing: The #1 Social Engineering Attack

Phishing tricks users into revealing credentials via fake emails, SMS, or websites. In 2025, AI makes phishing hyper-realistic with deepfake voices and personalized messages. 91% of breaches start with phishing. Attackers spoof banks, CEOs, or HR. Ethical Hacking Training Institute demos phishing in labs using SET and Gophish. Victims click malicious links or download malware. Spear phishing targets individuals. Whaling targets executives. Prevention includes email filters, MFA, and user training. Over 300,000 phishing sites appear daily. Real case: Twitter 2020 breach via phone spear phishing. Always verify sender. Never click unknown links. Report suspicious emails. Phishing evolves, but awareness stops it. Find the best local courses for phishing defense.

Ransomware: Encrypt and Extort

Ransomware encrypts files and demands payment in crypto. In 2025, double extortion adds data leaks. Groups like LockBit and Conti dominate. Average ransom: $1.5 million. Attackers use phishing, RDP brute force, or zero-days. Webasha Technologies teaches ransomware simulation in labs. Victims lose access until payment or recovery. Backup is key defense. Real case: Colonial Pipeline paid $4.4M in 2021. Patch systems, disable RDP, use EDR. Ransomware hits hospitals, schools, and governments. Never pay. Report to authorities. Recovery takes weeks. Prevention beats cure. Learn more about the CEH course ransomware module.
