Mosqito is a defensi tool for detecting Unicode homoglyph and IDN-based domain impersonation and phishing risks.

---

O

Unicode homoglyphs are frequently abused in phishing and brand impersonation attacks by replacing ASCII characters with similar Unicode characters.

Mosqito helps security professionals:

Detect Unicode-based domain masquerading

Generate potential homoglyph impersonation

Analyze suspicious domains during SOC triage

Understand IDN and Punycode abuse techniques

Mosqito is designed strictly for defensi research, detection engineering, and education.

---

Features

Unicode homoglyph domain generation

Masquerade detection for single domains

normalization and impersonation detection

Risk scoring for prioritization

IDN / Punycode identification

Colorized terminal output

- 🟢 Green: clean / low risk
- 🟠 Orange: suspicious / malicious-looking

Single-file, dependency-free Python tool

---

Installation

Clone the repository:

---
Mosqito requires Python 3.9 or higher.

No additional dependencies are required.
---

Usage

General Syntax

---

Options

| Option | Description | Default |
| ------------------------- | ---------------------------------------------------------- | -------- |
| -m, --max-changes <int> | Maximum homoglyph substitutions per label | 2 |
| --punycode | Display IDNA / Punycode representation | Disabled |
| --check | Analyze a domain for masquerading indicators | Disabled |
| --compare <domain> | Legitimate domain to compare against (used with --check) | None |

---

Examples

Generate Homoglyph

Generates similar Unicode-based of google.com.
---

Limit Substitutions (Higher Realism)

Restricts output to the most realistic impersonation domains.
---

Show Punycode Representation

Displays the IDN / ASCII-compatible encoding used by DNS and browsers.
---

Masquerade Detection Mode

Check whether a domain is likely impersonating another.
---

Compare Against a Legitimate Domain

This flags high-confidence impersonation.
