## MITRE ATT&CK Mapping
*Since the context describes a **defensive tool** against scareware, direct offensive TTP mappings are descriptive of the threat being countered rather than the tool itself. Scareware often falls under the execution and initial access phases targeting user deception.*
- TA0001 - Initial Access (Scareware often relies on tricking users into granting access)
- T1566 - Phishing (Social engineering aspect of scareware)
- T1588 - Obtain Capabilities (If scareware leads to purchasing fake software)
## Functionality
### Core Capabilities
- Detection of common scareware tactics (e.g., fake virus warnings, misleading notifications).
- Providing users with actionable steps or automatic intervention to stop the scareware attempt.
- Blocking fraudulent or manipulative pop-ups and redirects.
### Advanced Features
- Seamless integration within the Microsoft Edge browser environment.
- Focus on user education or explicit warnings regarding deceptive websites or processes associated with scareware.
