cyberbro

Cyberbro is a Python-based open-source application that parses unstructured logs and text to extract indicators of compromise (IoCs)—IPs, domains, hashes, URLs—then queries their reputation across 30+ threat intelligence services. It provides a web UI for analysis, CSV/Excel export, and integrates with EDR tools like Microsoft Defender and CrowdStrike.

What cyberbro is

Flask-based web application with multithreaded IoC extraction, SQLite result caching, and REST API. Supports proxy configuration, reverse DNS/RDAP pivoting, and integrations with VirusTotal, AlienVault, MISP, OpenCTI, and cloud security platforms. Deployed via Docker or direct Python/Gunicorn.

Quickstart

Get the cyberbro source

Clone the repository and explore it locally.

terminalbash

1git clone https://github.com/stanfrbd/cyberbro.git2cd cyberbro3# follow the project's README for install & configuration

Best use cases

Rapid Incident Triage

Security analysts can paste raw logs, alerts, or email content; Cyberbro automatically extracts and cross-checks IoCs against multiple CTI sources in seconds, reducing triage time.

Threat Hunting & OSINT

Teams using DFIR workflows can pivot on domains and IPs, fetch abuse contacts, and correlate observables with external threat reports and EDR data without context switching.

Lightweight CTI Hub for Teams

Organizations seeking an alternative to complex platforms like IntelOwl can deploy Cyberbro in minutes with Docker, manage free/API-keyed services, and share findings via browser extension or API.

Implementation considerations

API keys for multiple services (VirusTotal, AbuseIPDB, etc.) must be stored securely via .env file or external secret manager (Vault, SOPS); README warns against committing .env to version control.
Proxy configuration supported; ensure firewall rules permit outbound HTTPS to all integrated CTI APIs if corporate proxy is required.
SQLite default storage suitable for small-to-medium teams; concurrent access can bottleneck; production deployments should evaluate PostgreSQL migration path.
Multithreading enables fast parallel lookups; tuning thread pool and rate-limit handling depends on API quotas and network latency.
Docker Compose setup simplifies initial deployment; reverse proxy (nginx, Caddy) + WAF strongly recommended before exposing to production networks per README caution.

When to avoid it — and what to weigh

Enterprise-Scale Multi-Tenancy Required — Cyberbro stores results in SQLite and lacks built-in RBAC, audit logging, or multi-tenant isolation. Production teams needing strict data separation should use dedicated CTI platforms.
Real-Time Alert Correlation at Scale — No streaming ingestion, Kafka integration, or horizontal scaling. High-volume SOC environments processing thousands of alerts/min should evaluate specialized SIEM/CTI pipelines.
Offline or Air-Gapped Networks — Cyberbro requires outbound API calls to external threat services. Air-gapped deployments need pre-cached threat data or local mirrors, which are not provided.
Regulatory Compliance Focus — No explicit documentation on data retention, encryption at rest, or compliance controls (HIPAA, PCI-DSS). Teams with strict audit/retention policies should conduct security review.

License & commercial use

MIT License. Permissive OSI-compliant license allowing commercial use, modification, and distribution with minimal restrictions. Requires only retention of license and copyright notices.

MIT is a standard permissive license permitting commercial deployment and use. No license-based restrictions on profit-generating use. However, integrations with third-party SaaS CTI services (VirusTotal, Shodan, etc.) have their own commercial terms and may require paid API subscriptions for production use. Ensure compliance with each upstream service's ToS.

Security considerations

README cautions that production deployments require reverse proxy + WAF and warns that .env containing secrets must never be committed. No explicit mention of input validation hardening, rate limiting, or CSRF/XSS protections. Integration with EDR/MISP requires secure credential storage (third-party secret managers advised). SQLite default storage lacks encryption at rest. Third-party API key exposure risk if Flask debug mode left enabled. Recommend threat modeling before exposing to untrusted networks.

Alternatives to consider

IntelOwl (OSINT Framework)

Heavier, modular framework supporting 200+ analyzers; better for enterprise-scale deployments but steeper learning curve and higher resource footprint.

Cybergordon (Reputation Checker)

Cloud-hosted SaaS alternative; no infrastructure needed, but limited customization, potential privacy concerns, and ongoing subscription costs.

Cortex / MISP Integration

If MISP already deployed, Cortex responder + analyzer jobs offer native CTI enrichment; requires MISP infrastructure and Java runtime.

cyberbro FAQ

Do I need API keys to get started?

No. Free engines (some with rate limits) work without keys. Copy .env.sample to .env and leave optional values blank. Paid/restricted services (VirusTotal, Shodan) require API keys for full functionality.

Can I use Cyberbro offline or air-gapped?

No. Cyberbro queries external CTI APIs by design. Air-gapped networks require local threat intel mirrors or pre-cached data, neither of which is provided.

Is it suitable for a 100+ analyst SOC?

Unknown. SQLite default storage and lack of RBAC/audit logging limit multi-user deployments. Requires testing and likely PostgreSQL migration + reverse proxy hardening for production SOCs.

How do I integrate Cyberbro with my SIEM?

API endpoints available at /api/. REST calls can be triggered from SIEM playbooks or search queries. No pre-built SIEM connectors documented; integration is custom.
