Fast and customisable parameter based vulnerability scanner based on simple YAML Rules

How • Install • Templates • Interceptor • Usage • Join Discord

Erebus is used to test every parameter across targets based on Yaml templates leading to zero false positives and providing fast scanning on large number of hosts. Erebus offers many useful features including an intercepting proxy which allows researchers to browse the web, click on links and erebus will test every parameter that passes through the proxy.

We have a dedicated repository that houses various types of vulnerability templates.

How templates work

Install Erebus

▶  GO111MODULE=off go get -u -v github.com/ethicalhackingplayground/erebus/erebus

Install Templates

▶  erebus -ut

Erebus Templates

Erebus has had built-in support for automatic update/download templates (https://github.com/ethicalhackingplayground/erebus/releases/latest). Erebus-Templates project provides a community-contributed list of ready-to-use templates that can be used with part of your testing.

You may use the -ut flag to update the nuclei templates at any time.

▶ Settings ▶ General ▶ Network Settings ▶ Manual proxy configuration

type in 127.0.0.1 in HTTP Proxy then for the port type in 8080 make sure to enable Also use this proxy for FTP and HTTPS

Install the SSL Certificates to use HTTPS
