Revealing Hidden Password Vulnerabilities with Substring Analysis

by | Jan 31, 2025 | Blog

In the rapidly changing world of cybersecurity, one truth remains: passwords continue to be a primary target for attackers. Even as new authentication methods emerge, many organizations still rely on traditional password-based security. That’s why investing in smarter, more comprehensive password analysis is critical to protecting your business from data breaches and cyber threats.

One of the most innovative approaches in this area is substring analysis, a technique designed to expose deeper, often organization-specific password weaknesses that conventional dictionary checks simply miss.

 

Traditional Password Analysis—and Its Gaps

Analysts have used dictionary word analysis to find identify base-words (e.g., “welcome” or “winter”) in passwords for decades. While it’s effective at spotting common English words, these methods rarely detect subtle patterns unique to your organization.

For instance, internal project names, building addresses, product acronyms, or insider terms that employees frequently use all go unnoticed by standard dictionary checks. Similarly, numeric suffixes like `2025##` may be used systematically across employee passwords and remain hidden if you rely on dictionary analysis alone.

 

Why Substring Analysis Matters

Substring analysis zeroes in on any recurring sequence of characters—regardless of whether it’s a recognizable word. This expanded scope helps businesses spot all kinds of “invisible” vulnerabilities:

  • Company-Specific Keywords: Project names, code words, or departmental acronyms that employees often embed in their passwords.
  • Repeatable Patterns: Identical character sequences that recur across large swaths of user accounts—even if they aren’t dictionary words.
  • Multi-Language Insights: Substring analysis doesn’t require multiple dictionaries for different languages, industry jargon, or specialized terms.

By illuminating how users build passwords, organizations gain greater clarity on where they’re most exposed, and how best to fix it.
