Overview

Arachni is a feature-rich, modular, high-performance Ruby framework aimed at helping penetration testers and administrators evaluate the security of modern web applications. Developed with a focus on usability and modularity, Arachni provides comprehensive web application security assessment capabilities through its advanced crawling engine, extensive vulnerability detection modules, and flexible reporting system. The framework is designed to handle complex modern web applications including those with heavy JavaScript usage, AJAX functionality, and dynamic content generation.

The framework distinguishes itself through its intelligent crawling capabilities and comprehensive vulnerability detection. Arachni can effectively analyze single-page applications (SPAs), REST APIs, and traditional web applications with equal proficiency. Its modular architecture allows for easy customization and extension, making it suitable for both automated security testing and manual penetration testing workflows. The platform includes advanced features such as browser clustering for JavaScript-heavy applications, custom payload generation, and sophisticated false positive reduction mechanisms.

Arachni's strength lies in its ability to perform both black-box and gray-box security testing. The framework can operate in various modes, from quick security scans to comprehensive deep-dive assessments. It includes built-in support for authentication, session management, and complex multi-step attack scenarios. The platform's reporting capabilities generate detailed technical reports suitable for developers, executive summaries for management, and compliance documentation for regulatory requirements.

The framework is particularly valuable for organizations requiring regular security assessments of web applications. Its automation capabilities make it suitable for integration into CI/CD pipelines, while its comprehensive manual testing features support detailed penetration testing engagements. Arachni's active development community ensures regular updates to address emerging web application security threats and testing methodologies.

```## Fehlerbehebung

Häufige Probleme und Lösungen

```bash

Issue: Memory errors during large scans

Solution: Increase memory limits and use browser clustering

arachni http://example.com \ --http-request-concurrency=5 \ --browser-cluster-pool-size=2 \ --scope-page-limit=500 \ --timeout=7200

Issue: Timeouts on slow applications

Solution: Increase timeout values

arachni http://example.com \ --http-request-timeout=60000 \ --http-request-delay=2000 \ --timeout=14400

Issue: False positives in results

Solution: Use verification plugins and custom filters

arachni http://example.com \ --checks=xss,sqli \ --plugin=verification:verify_xss=true,verify_sqli=true

Issue: Incomplete crawling of JavaScript applications

Solution: Enable browser clustering and increase wait times

arachni http://example.com \ --browser-cluster-pool-size=3 \ --browser-cluster-job-timeout=60 \ --scope-auto-redundant=10

Issue: Authentication session expires during scan

Solution: Use session management plugins

arachni http://example.com \ --plugin=autologin:url=http://example.com/login,parameters="user=admin&pass=secret" \ --session-check-url=http://example.com/profile \ --session-check-pattern="Welcome"

Issue: Scan getting blocked by WAF/rate limiting

Solution: Implement delays and use proxy rotation

arachni http://example.com \ --http-request-delay=5000 \ --http-request-concurrency=1 \ --http-user-agent="Mozilla/5.0 (compatible; Scanner)"

Issue: Large report files

Solution: Use specific checks and limit scope

arachni http://example.com \ --checks=xss,sqli,csrf \ --scope-page-limit=100 \ --scope-depth-limit=3

Issue: SSL/TLS certificate errors

Solution: Disable certificate verification

arachni https://example.com \ --http-ssl-verify-peer=false \ --http-ssl-verify-host=false ```### Leistungsoptimierung

```bash

Optimize for speed

arachni http://example.com \ --http-request-concurrency=20 \ --http-request-delay=100 \ --scope-page-limit=200 \ --checks=xss,sqli \ --timeout=1800

Optimize for thoroughness

arachni http://example.com \ --http-request-concurrency=5 \ --http-request-delay=1000 \ --scope-page-limit=2000 \ --scope-depth-limit=10 \ --checks=* \ --plugins=* \ --timeout=14400

Optimize for JavaScript-heavy applications

arachni http://example.com \ --browser-cluster-pool-size=4 \ --browser-cluster-job-timeout=30 \ --browser-cluster-worker-time-to-live=200 \ --scope-auto-redundant=15 \ --timeout=10800

Memory optimization for large scans

export RUBY_GC_HEAP_INIT_SLOTS=1000000 export RUBY_GC_HEAP_FREE_SLOTS=500000 export RUBY_GC_HEAP_GROWTH_FACTOR=1.1 export RUBY_GC_HEAP_GROWTH_MAX_SLOTS=1000000

arachni http://example.com \ --http-request-concurrency=10 \ --scope-page-limit=1000 \ --timeout=7200 ```---
