virustotal 0.6.0

Breaking Changes

• Removed VirusTotal API v2.0 Support: Completely removed all v2.0 API functions (virustotal2_GET(), virustotal2_POST()) and deprecated functions (add_comments()). The package now exclusively uses VirusTotal API v3.0.

New Features

• Analysis Endpoint: Added get_analysis() to retrieve analysis results by ID.

• File Behaviour Endpoints: New functions for sandbox analysis:

  • get_file_behaviour_summary(): Summary of all behaviour reports
  • get_file_behaviour_mitre_trees(): MITRE ATT&CK technique mappings
  • get_file_behaviours(): All behaviour reports for a file

• Sandbox Report Endpoints: Access individual sandbox artifacts:

  • get_behaviour_report(): JSON behaviour report
  • get_behaviour_html(): HTML report from sandbox
  • get_behaviour_evtx(): Windows Event Log file
  • get_behaviour_pcap(): Network capture file
  • get_behaviour_memdump(): Memory dump file

Package Simplification

• Streamlined Architecture: Simplified codebase by removing dual API support.
• Enhanced Documentation: Updated all documentation for v3.0-only support.

Migration Guide

Users upgrading from versions that used v2.0 functions should ensure their code uses the equivalent v3.0 functions.

virustotal 0.5.0

Major Updates

• Modernized Package Architecture: Complete modernization of the virustotal package with enhanced security, error handling, and user experience.

New Features

• Structured Error Handling: New S3 error classes (virustotal_error, virustotal_auth_error, virustotal_validation_error, virustotal_rate_limit_error) provide detailed error information and better debugging.

• S3 Response Classes: All API responses now return structured S3 objects (virustotal_file_report, virustotal_domain_report, etc.) with custom print() and summary() methods for better user experience.

• Modern Rate Limiting: Replaced environment variable-based rate limiting with a sliding window implementation that properly manages the 4 requests/minute VirusTotal API limit.

• Comprehensive Input Validation: Added robust input validation using the checkmate package with security-focused sanitization functions.

• Enhanced Security Utilities: New security functions for safe file operations and input sanitization to prevent common security issues.

Infrastructure Improvements

• Updated CI/CD: Migrated from Travis CI/AppVeyor to GitHub Actions with comprehensive testing matrix (R oldrel-1, release, devel).

• Modern Dependencies: Updated minimum R version to 4.0.0, migrated from plyr to dplyr, added modern packages (checkmate, jsonlite, rlang).

• Enhanced Documentation: Improved documentation with roxygen2 markdown support and comprehensive examples.

• Test Coverage: Expanded test suite with proper mocking support and comprehensive error handling validation.

API Enhancements

• Improved Domain Processing: Enhanced domain cleaning logic that properly handles URLs with protocols, www prefixes, and paths.

• Better Error Messages: More informative error messages with parameter context and suggested fixes.

• Response Formatting: Rich response formatting with detection summaries, file metadata, and threat intelligence display.

Breaking Changes

• Minimum R version increased from 3.3.0 to 4.0.0
• Some internal functions have been refactored (not user-facing)
• Error objects now use structured S3 classes instead of simple character strings

Bug Fixes

• Fixed rate limiting edge cases and timing issues
• Improved handling of malformed API responses
• Enhanced validation precedence for better test compatibility
• Fixed Unicode character encoding in utility functions

Development Tools

• Added virustotal_info() function for package configuration diagnostics
• Enhanced rate limit status reporting with get_rate_limit_status()
• Improved temporary file management with security-focused utilities

New Features

• Enhanced input validation for all functions
• Automatic URL encoding for v3 API compatibility
• Improved error messages with actionable guidance
