Platform Introduction

John the Ripper is a powerful, open-source password cracking tool designed to detect weak credentials across local systems, networked environments, and connected infrastructure. At Cyber Security Testing Pro, we use John the Ripper to audit authentication security within IoT platforms, smart utility portals, and industrial systems. By applying brute-force, dictionary, and rule-based attacks, our experts can identify exploitable credentials that compromise the integrity of critical infrastructure. Based in Canoga Park, CA, Cyber Security Testing Pro helps North American enterprises and municipalities integrate John the Ripper into proactive security assessments, ensuring that password hygiene and access control mechanisms meet today’s cybersecurity standards.

Case Studies

U.S. Electric Grid Operator – Pennsylvania

Cyber Security Testing Pro deployed John the Ripper to audit administrator credentials across 250+ substation control systems. Within one week, 18% of passwords were flagged as weak or default. Policy revisions were implemented immediately, improving NERC CIP audit readiness.

U.S. Transportation Agency – Nevada


Cyber Security Testing Pro integrated John the Ripper into the security test workflow for browser-based dashboards managing smart traffic signals. Several field engineer credentials were cracked using a simple dictionary attack, leading to an agency-wide password reset and MFA enforcement.

Canadian Public Utility – Manitoba


A Canadian water treatment utility used John the Ripper via Cyber Security Testing Pro to assess password strength across remote monitoring equipment. The assessment helped identify legacy authentication systems with outdated hashes, enabling a secure transition to salted SHA-512 policies.
