Slasher - Bulk VirusTotal Indicator Lookups

Slasher is a bulk IOC checker. Paste hashes, IPs or domains, let Slasher query VirusTotal in parallel, watch progress live, then export results as a CSV file — all from a single web interface.

Features

• Bulk look-ups: Drop in MD5 / SHA-1 / SHA-256, FQDNs or IP v4/v6; all are queried concurrently.
• Filter + search: Text search, per-column filters and sorting help you find the needles fast.
• Risk colouring: Badges turn green / amber / red based on how many VT engines flagged the indicator.
• One-click sample download: If VT hosts the file you can fetch it straight from the table.
• CSV export: One button, ready-to-share CSV (server-side stream, no browser freeze).
• Zero-friction setup: `docker compose up --build`` brings up API & UI in one go.

Getting started

Clone

git clone https://github.com/hexastrike/slasher.git

Generate a Django secret:

from django.core.management.utils import get_random_secret_key
print(get_random_secret_key())

Edit .env and set at least:

DJANGO_SECRET_KEY=<your-secret-key>
VIRUSTOTAL_API_KEY=<your-virustotal-key>

Run

docker compose up --build # API on port 8000, UI on port 3000 by default

Roadmap

• XLSX export
• Use cached VirusTotal results
• Export / copy only selected rows
• Additional enrichment sources (Abuse-IPDB, URLhaus, Hybrid-Analysis …)
• Authentication
