Cybercriminals are becoming smarter every day, and one of the most dangerous tricks in their arsenal is the homoglyph attack. This scam is so subtle that even experts can fall for it — because the fake websites look exactly like the real ones. Let’s break it down step by step.
What Are Homoglyphs?
A homoglyph is a character that looks identical (or very similar) to another character but is actually different in Unicode. For example: Latin "a" and Cyrillic "а". Both look like "a", but the second one is a completely different character from a different script.
"Example: Real vs Fake. At first glance, faceboook.com (fake) looks the same as facebook.com (real). But hidden inside are characters from Cyrillic or Greek alphabets."
Why Are Homoglyph Attacks Dangerous?
- //Phishing: Fake login pages that steal usernames & passwords
- //Credit Card Theft: Fake e-commerce pages that collect payments
- //Malware Delivery: Fake downloads that install spyware or ransomware
- //BEC: Lookalike email domains trick employees into wiring money
- //Brand Reputation: Users believe your company is a scammer
"All it takes is one wrong click on a fake site to compromise your identity, your money, or your entire company."
