SSL Search

Hunt SSL Certificates for interesting keywords on major cloud service providers.

Details - https://medium.com/@harsh8v/ssl-search-a-tool-to-identify-infrastructure-and-discover-attack-surfaces-449c83269574

Installation

• install as a CLI tool for quick one-off scans

git clone https://github.com/superbinves/sslsearch.git
cd sslsearch
go install

• run as a docker container

docker run ghcr.io/harshvaragiya/sslsearch:main

Features

• Search Cloud Service Providers IP Ranges / Given IP CIDR for keywords in SSL Certificate Subject / SANs
• Perform JARM fingerprinting of https services identified
• Grab all http response headers for webservers
• Export integrations for Disk (local file), Elasticsearch, Cassandra / ScyllaDB

More details about export targets at : docs/Export.md

Cloud Service Provider	Region String Example	JARM	Server Header
Amazon Web Services	us-east-1	✅	✅
Cloudflare	-	✅	✅
Digital Ocean	NL_NL-NH_Amsterdam	✅	✅
Google Cloud Platform	us-west4	✅	✅
Oracle Cloud Infrastructure	ca-montreal-1	✅	✅
Raw CIDR / IP Range	-	✅	✅

Potential uses

1. Identifying Infrastructure / Attack Surface for a given scope.
2. Bug Bounty recon.
3. Scanning a whole CSP Region & Identifying Servers / Services of interest along with SSL certificate information.
4. Scanning the whole Internet / Country's CIDRs & Collecting JARM fingerprints / Server Headers along with SSL certificate information.
5. Finding Mail / RDP / Other services belonging to a target that use x509 certificates to secure connections.

Future plans (not a roadmap)

• Export integrations for cassandra cluster
• Export integration for elasticsearch
• Grab all HTTPS server response headers
• Added profile guided optimization (PGO)
• Added background worker (job queueing) using redis
• Add k8s example deployments, with cronjob for scheduling tasks, executing them
• CI/CD Setup with docker image
• Export integration to NATS
• QOL - Split codebase into different packages like libexport, libscan for better code quality.
• Certificate information like issuer, signature, chain etc to also be stored for analysis.
• Integration tests with test docker containers??.
