GitHub Arsenal: Open Source Tools for Fighting Cybercrime

The fight against cybercrime is a global effort, and the open-source community plays a crucial role. GitHub, as the world's leading platform for software development, hosts a vast array of tools designed to detect, analyze, and combat various cyber threats, including the pervasive menace of phishing.

The Power of Open Source in Cybersecurity

Open-source projects offer unparalleled transparency, allowing security researchers and developers worldwide to scrutinize code, identify vulnerabilities, and contribute to improvements. This collaborative model fosters rapid innovation and creates robust, community-vetted solutions against sophisticated cyberattacks.

Key Resources for Phishing Combat

Beyond general cybersecurity tools, several specialized resources are invaluable for directly combating phishing attempts. These tools range from real-time threat feeds to URL analysis services and community-driven blocklists:

• TweetFeed.live: Provides a live feed of cyber threat intelligence, often including early warnings about phishing campaigns shared on social media.
• Phish.Report: A platform for reporting phishing sites, contributing to a collective database that helps block malicious URLs.
• URLQuery.net: Offers a free service to analyze suspicious URLs, providing detailed reports on their behavior and potential threats.
• ThreatView.io Experimental IOC Tweets: A raw data feed of Indicators of Compromise (IOCs) extracted from tweets, useful for automated threat detection systems.
• Polkadot-JS Phishing Repository: A GitHub repository dedicated to tracking and detecting phishing attempts targeting the Polkadot ecosystem.
• URLAbuse.com Public Data: Provides a public list of reported abusive URLs, which can be used to update blocklists.
• MetaMask/eth-phishing-detect: An open-source project by MetaMask to detect and prevent Ethereum-related phishing attempts.
• Phishing.Army Blocklist: A regularly updated blocklist of known phishing URLs, maintained by the Phishing.Army community.
• VirusTotal URL Analysis: A widely used service that analyzes suspicious files and URLs, providing insights from multiple antivirus engines and blacklisting services.
• Phish Guard Blue: A web application designed to help users identify and avoid phishing links.
• Netcraft Phishing Report: Netcraft's platform for reporting phishing sites, contributing to their comprehensive anti-phishing efforts.
• Seal Phishing Bot (Telegram): A Telegram bot that helps users check links for phishing and report suspicious activity.
• URLScan.io: A free service that scans and analyzes websites, providing detailed reports on their content, technologies, and potential malicious activities.

OSINT Investigators' Toolkit

Beyond block-lists, real investigation requires deeper instrumentation. The following open-source tools form the backbone of any phishing-takedown workflow — each is free, scriptable, and battle-tested by the community:

• urlscan.io — sandboxed URL analysis: full DOM snapshot, screenshots, network calls, certificate details. Indispensable for evidence preservation before takedown.
• VirusTotal — multi-engine reputation lookup for URLs, files, IPs, and hashes. Submitting a phishing URL here propagates detection to dozens of AV/EDR vendors.
• Shodan — internet-of-things and exposed-service search engine. Used to map scammer infrastructure, identify hosting clusters, and discover panels.
• Censys — certificate-transparency & banner search; pivoting from one TLS cert to a hundred related domains is routine here.
• crt.sh — free Certificate Transparency log search, perfect for catching newly-issued look-alike certs against protected brands.
• Wayback Machine — preserves snapshots that survive even after the original site disappears.
• WHOIS & ViewDNS.info — registrant lookups, reverse-IP, and DNS pivoting.
• Maltego CE — graph-based link analysis; ideal for visualizing scammer networks across email, domain, IP, and social-media nodes.
• theHarvester — collects emails, subdomains, hosts, and employee names from public sources.
• Kali Linux — pre-loaded distro with hundreds of OSINT and security tools.

Browser-Side Defenses

Most phishing victims are caught on the click. Browser-layer defenses stop the attack before it ever reaches the wallet:

• MetaMask eth-phishing-detect — domain blocklist that ships with MetaMask and many Web3 wallets, blocking known phishing pages before they load.
• PhishDestroy destroylist — 130K+ curated active scam & phishing domains, multiple formats (DNS, hosts, JSON, CSV) ready for integration with Pi-hole, AdGuard, browser extensions, or corporate firewalls.
• PhishFort lists — community-maintained crypto-phishing blocklists.
• uBlock Origin + Privacy Badger — filter ads and trackers, dramatically reducing exposure to malvertising delivery channels.
• ScamSniffer — Web3 scam-database extension that surfaces drainer-contract risk on-page.

Threat-Intelligence Feeds

If you operate a SOC, CERT, or security stack, ingest these public feeds for active phishing infrastructure:

• destroylist — auto-updated, 130K+ threats, free API, multiple formats.
• OpenPhish — community phishing feed with clean text format.
• PhishTank — verified-phishing URLs (Cisco/OpenDNS).
• URLhaus (abuse.ch) — malware-distribution URLs.
• TweetFeed — IOCs scraped from infosec social media.
• ScamSniffer scam-database — Web3 blacklists.

YARA, Honeypots & Active Defense

• PhishingKit-Yara-Rules — detect known phishing-kit fingerprints in HTML/JS.
• Yara-Rules — community-maintained rule library.
• Honeypots & canary tokens — canarytokens.org, MazeRunner CE.
• Operation-Takedown — our own collection of scripts for active phishing-campaign disruption.

Workflow — From Tip to Takedown

A typical investigation chains these tools together:

1. Receive a lead — a community report (Telegram bot), a paid-ad parser hit, or a CT-log alert.
2. Confirm phishing — sandbox via urlscan.io; cross-check with VirusTotal, OpenPhish, PhishTank.
3. Map infrastructure — pivot via Censys/Shodan to find related domains, IPs, certificates.
4. Preserve evidence — Wayback snapshot, urlscan archive, full HTML/JS capture, screenshots.
5. Notify partners — submit to 50+ AV vendors, file abuse with registrar/host, syndicate to MetaMask & ScamSniffer feeds.
6. Monitor — confirm takedown; watch for resurfacing on neighboring IPs or freshly-registered look-alikes.
