Character Addition
Inserts an extra character at every position in the domain. Catches users who accidentally hit an adjacent key.
How It Works
This technique inserts every letter (a-z) at every position in the domain name. It generates a large number of variations (26 × N+1 positions). It catches scenarios where users accidentally press an extra key while typing, or where attackers create plausible-looking extended domain names.
Real-World Examples
- googles.com (adding "s" to google)
- faceboook.com (adding extra "o")
- twitterr.com (adding extra "r")
Prevention Tips
- Due to the high volume of variations, focus on registering additions that form real words or common patterns.
- Monitor for additions that create plural forms or common suffixes (-ing, -ed, -er).
- Use wildcard DNS monitoring to catch any new domains similar to yours.
