Character Transposition
Swaps adjacent characters, mimicking a very common typo where users reverse the order of two nearby keys.
How It Works
This technique swaps each pair of adjacent characters. It exploits the very common typing error where fingers hit keys in the wrong order. For N characters, it produces N-1 variations. Transposition is particularly effective for fast typists who often reverse character pairs.
Real-World Examples
- googel.com (swapping "l" and "e" in google)
- faecbook.com (swapping "c" and "e" in facebook)
- mircosoft.com (swapping "c" and "r" in microsoft)
Prevention Tips
- Register the most likely transposition variants, especially for adjacent vowel-consonant pairs.
- Use DMARC email authentication to prevent phishing from transposed domains.
- Implement automated scanning to detect new transposition registrations.
