About this site

Cold Start Beverage Co. is not a real company. It is a fictional food and beverage manufacturer created as the running scenario for Mike Holcomb’s book on industrial (OT/ICS) penetration testing, written to help defenders understand how attackers approach industrial environments.

The people, plant, products, addresses, phone numbers and events on this site are invented. Any resemblance to real people or companies is coincidental. Phone numbers use the reserved 555-01xx range, and every IP address shown is from ranges reserved for documentation (RFC 5737), so none of them belong to a real system.

Readers are welcome to use this site for the open-source intelligence (OSINT) exercises in the book. Please keep your exercises passive: read the site, view its source and use public search tools. Do not scan, attack or try to log in to anything, including this web server and its hosting provider.
