CyberDudeBivash Roars: In 2026, your email address is not private — it is currency. Your password is not secret — it is already for sale. Credential stuffing, ransomware initial access, business email compromise (BEC), and targeted spear-phishing all begin with one simple truth: someone, somewhere, already has your credentials.

I ran my own tool on a test email this morning: 271 breaches found. That is not an outlier — it is the norm. The dark web is flooded with billions of exposed records. IOCs (indicators of compromise) are the fingerprints left by attackers. Ignoring them is not negligence — it is surrender.

This is why I built the CYBERDUDEBIVASH IOC & Breach Checker v1.1 — a free, open-source, production-ready security tool designed to give individuals, security teams, and organizations immediate visibility into exposures and active threats.

The Harsh Reality of Credential Exposure in 2026

According to HaveIBeenPwned (HIBP), over 12 billion accounts have been compromised across more than 700 breaches as of early 2026. In India alone, the CoWIN leak (81.5 crore Aadhaar-linked records), Air India breach (4.5 million flyers), and ongoing UPI credential harvesting have created a perfect storm for identity theft and financial fraud.

Credential stuffing attacks — where attackers use leaked username/password pairs to try logging into other services — now account for over 80% of account takeovers in financial and e-commerce sectors (Akamai 2026 State of the Internet Report). Once inside, attackers pivot to ransomware deployment, wire fraud, or data exfiltration.

IOCs (malicious URLs, IPs, file hashes) are the breadcrumbs that lead back to these campaigns. Yet most organizations and individuals have no automated way to continuously check for exposure.

That ends today.

Introducing CYBERDUDEBIVASH IOC & Breach Checker v1.1

This is not another toy script. It is a lightweight, secure, production-grade security tool built with the same rigor I apply to client engagements at CYBERDUDEBIVASH PVT LTD.

Core Capabilities:

Breach exposure scanning for emails and passwords using HaveIBeenPwned (k-anonymity protocol — your full data is never sent)
IOC lookup on VirusTotal for URLs, IP addresses, and file hashes (malware, phishing, suspicious reputation)
Batch scanning — process hundreds or thousands of items via JSON input
JSON output — perfect for SIEM integration, automation pipelines, or reporting
Forensic-grade logging — every scan is timestamped and auditable
100% local execution — zero cloud dependency, zero telemetry, zero risk of data leak

How It Works (Technical Deep Dive)

Email & Password Breach Check Uses the HaveIBeenPwned k-anonymity API — only the first 5 characters of the SHA-1 hash are sent to the server. No full credential is ever transmitted. Returns breach count (if any).
IOC Lookup on VirusTotal Queries VT’s v3 API for reputation, detection ratio, and threat classification. Requires a free/public VT API key (rate-limited to 4 requests/minute — paid keys support higher throughput).
Batch Mode Feed a JSON array — scan dozens or hundreds of emails, passwords, URLs, IPs, hashes in one go. Ideal for red-team exercises, incident response, or employee credential audits.
Security Design Principles
- No credential storage — everything is processed in memory and discarded.
- No telemetry — tool never phones home.
- Open-source with clear proprietary branding — free for personal/research use; commercial licensing available.

Real-World Use Cases

Individual users — Check if your personal email/password has been exposed before changing it.
Security teams — Run batch scans on employee email lists during onboarding/offboarding or after a suspected breach.
Incident responders — Quickly validate IOCs (malicious URLs/IPs/hashes) during live investigations.
Red teams & pentesters — Scan target environments for known compromised credentials.
Fintech & banking — Integrate into CI/CD pipelines to block credential reuse in test environments.

Installation & Quick Start

Bash

			
git clone https://github.com/cyberdudebivash/CYBERDUDEBIVASH-IOC-BREACH-CHECKER.git
cd CYBERDUDEBIVASH-IOC-BREACH-CHECKER
pip install -r requirements.txt

Basic usage examples: Bash

			
# Single email check
python cyberdudebivash_ioc_breach_checker.py --email "yourname@company.com"
# Single password check (hashed – safe)
python cyberdudebivash_ioc_breach_checker.py --password "P@ssw0rd123"
# IOC check (URL example)
python cyberdudebivash_ioc_breach_checker.py --ioc "malicious-example.com" --type url
# Batch scan from JSON file
python cyberdudebivash_ioc_breach_checker.py --batch batch.json --json

		

Sample batch.json JSON

			
[
  {"email": "test1@company.com"},
  {"password": "Summer2025!"},
  {"ioc": "8.8.8.8", "type": "ip"},
  {"ioc": "e99a18c428cb38d5f260853678922e03", "type": "hash"}
]

		

Roadmap & Future Enhancements

Integration with AbuseIPDB, Shodan, GreyNoise for richer IOC context
Dark-web keyword monitoring (domain/email alerts)
Email/SMS/Slack/Telegram alerts on new breaches
Enterprise dashboard (Streamlit or Flask-based)
API wrapper for SIEM/SOAR integration
