Addition
Extra Character Insertion
Adds duplicate characters to create convincing variations that users might not notice.
How It Works:
Systematically adds extra characters at strategic positions within the domain name.
Real Examples:
- google.com → googgle.com (extra ‘g’)
- facebook.com → facebookk.com (extra ‘k’)
- paypal.com → paypall.com (extra ‘l’)
- amazon.com → ammazon.com (extra ‘m’)
- twitter.com → twitterr.com (extra ‘r’)
⚠️ Why It’s Dangerous:
Users typing quickly often don’t notice the extra character, especially on mobile devices. The additional character appears natural and doesn’t trigger suspicion.
Bitsquatting
Memory Bit-Flip Exploitation
Exploits hardware-level bit-flip errors in computer memory (cosmic rays, hardware defects, electrical interference).
How It Works:
When a single bit flips in memory (0→1 or 1→0), the ASCII character changes. Attackers register domains matching these predictable bit-flip patterns.
Real Examples:
- google.com → gmogle.com (bit flip: o→m)
- amazon.com → amczon.com (bit flip: a→c)
- facebook.com → facebgok.com (bit flip: o→g)
- microsoft.com → microsmft.com (bit flip: o→m)
- apple.com → apple.aom (bit flip: c→a)
⚠️ Why It’s Dangerous:
Happens automatically without user error. Hardware-level errors redirect users to malicious sites without any typographical mistake.
Homoglyph
Visually Similar Characters
Uses characters from different alphabets (Cyrillic, Greek) that look identical to Latin characters.
How It Works:
Replaces Latin characters with visually identical characters from other Unicode character sets.
Real Examples:
- google.com → gооgle.com (Cyrillic ‘о’)
- paypal.com → рaypal.com (Cyrillic ‘р’)
- apple.com → аpple.com (Cyrillic ‘а’)
- microsoft.com → miсrosoft.com (Cyrillic ‘с’)
- amazon.com → аmazon.com (Cyrillic ‘а’)
⚠️ Why It’s Dangerous:
Visually indistinguishable from legitimate domains in browser address bars. Even security-conscious users cannot detect the difference without technical tools.
Hyphenation
Strategic Hyphen Placement
Inserts hyphens between characters to create convincing-looking domains.
How It Works:
Adds hyphens between syllables, words, or characters where users might expect them.
Real Examples:
- google.com → g-oogle.com
- facebook.com → face-book.com
- paypal.com → pay-pal.com
- microsoft.com → micro-soft.com
- youtube.com → you-tube.com
⚠️ Why It’s Dangerous:
Hyphens appear intentional and professional. Many legitimate brands use hyphens, making these variations highly believable.
Insertion
Character Insertion
Inserts additional characters at various positions within the domain.
How It Works:
Adds random but plausible characters throughout the domain name.
Real Examples:
- google.com → googzle.com
- amazon.com → amazxon.com
- paypal.com → paypxal.com
- facebook.com → facebxook.com
- twitter.com → twitxter.com
⚠️ Why It’s Dangerous:
Creates brand-new variations that spelling checkers don’t catch. The inserted characters feel natural and don’t immediately appear malicious.
Omission
Character Removal
Removes characters from the domain name, exploiting common typing errors.
How It Works:
Systematically removes individual characters from the domain.
Real Examples:
- google.com → gogle.com
- facebook.com → faceboo.com
- amazon.com → amzon.com
- microsoft.com → microoft.com
- youtube.com → youtub.com
⚠️ Why It’s Dangerous:
Mirrors common typing mistakes. Users who type quickly often skip characters without noticing.
Repetition
Character Duplication
Repeats existing characters within the domain.
How It Works:
Doubles or triples characters already present in the domain name.
Real Examples:
- google.com → gooogle.com
- twitter.com → twitterr.com
- apple.com → appple.com
- yahoo.com → yaahoo.com
- reddit.com → redddit.com
⚠️ Why It’s Dangerous:
Feels like enthusiastic branding or intentional variation. Some legitimate brands use repeated letters for emphasis.
Replacement
Character Substitution
Replaces characters with visually or phonetically similar alternatives.
How It Works:
Substitutes characters with numbers or letters that look similar (leet speak patterns).
Real Examples:
- google.com → goog1e.com (1 for l)
- microsoft.com → micros0ft.com (0 for o)
- facebook.com → faceb00k.com (0 for o)
- paypal.com → paypa1.com (1 for l)
- amazon.com → amaz0n.com (0 for o)
⚠️ Why It’s Dangerous:
Common in intentional “cool” domain names and brand variations. Users have been conditioned to accept these substitutions as normal.
Subdomain
Malicious Subdomain Creation
Creates fake subdomains that incorporate the legitimate domain name.
How It Works:
Places the target domain as a subdomain of a malicious domain.
Real Examples:
- google.com → google.com-login.phish.com
- paypal.com → secure-paypal.com.scam.info
- amazon.com → amazon.com-account.malicious.org
- microsoft.com → login-microsoft.com.phishing.site
- apple.com → appleid.apple.com-security.bad.com
⚠️ Why It’s Dangerous:
The legitimate domain appears in the URL, fooling users who only glance at the beginning or middle of the address bar. Extremely effective in phishing emails.
Transposition
Adjacent Character Swapping
Swaps adjacent characters, exploiting common typing errors.
How It Works:
Switches positions of neighboring characters.
Real Examples:
- google.com → gogole.com
- amazon.com → amzaon.com
- facebook.com → facebok.com
- paypal.com → paypla.com
- microsoft.com → micrsoft.com
⚠️ Why It’s Dangerous:
One of the most common typing errors. Fingers often hit keys in the wrong order when typing quickly.
Various
Multi-Technique Combinations
Combines multiple fuzzing techniques simultaneously.
How It Works:
Applies 2+ techniques (addition + hyphenation, omission + replacement, etc.) to create sophisticated variations.
Real Examples:
- google.com → goog-le.com (hyphenation + omission)
- facebook.com → fase-book.com (replacement + hyphenation)
- paypal.com → pay-pa1.com (hyphenation + replacement)
- amazon.com → amaz0n-shop.com (replacement + addition)
- microsoft.com → micr0s0ft.com (multiple replacements)
⚠️ Why It’s Dangerous:
Creates highly sophisticated variations that combine the effectiveness of multiple attack vectors. Harder to detect with simple pattern matching.
Vowel-Swap
Vowel Substitution
Replaces vowels with other vowels.
How It Works:
Systematically substitutes a, e, i, o, u with each other.
Real Examples:
- google.com → gaagle.com
- facebook.com → fecebook.com
- amazon.com → amezon.com
- paypal.com → peypal.com
- microsoft.com → macrosoft.com
⚠️ Why It’s Dangerous:
Vowel confusion is common in pronunciation-based typing. Users often remember consonants better than vowels, making these variations believable.
