This analyzer enables searching for md5 hashes in hash list. It does not download samples for you nor links directly to the sample - the author of virusshare prohibits the automatic download/site scraping and I respect that. It provides a button to start the virusshare search, though, but you need an account for that. You can request an invitation to the platform through contacting the admin via mail, directly.

9.1. Configuration

In order to check md5-hashes against the hash lists, a directory containing the lists must be provided in cortex config:

Virusshare {

9.2. Download the newest hash lists

9.2.1. Usage

In order to download the newest available hash lists from, you can run the script.

./ /path/to/your/download/directory

It takes a lot of time to download. The files are names 000.md5 - xxx.md5 and already available files are skipped.
