Credential stuffing attacks are one of the most common and successful forms of identity-based cyberattacks. That’s why we’re excited to introduce a major enhancement to Cayosoft Guardian: Password Hash Analysis with Breached Password Detection. This feature helps security teams identify and address compromised credentials inside Active Directory before attackers exploit them.
How Cayosoft Guardian Detects Breached Passwords
The new Password Hash Analysis feature in Cayosoft Guardian compares Active Directory password hashes against a dynamic list of known breached credentials without decrypting them.
With this feature, security teams can:
- Identify compromised passwords in Active Directory
- Detect reused credentials in user and service accounts
- Detect blank and weak passwords
- Gain visibility into password hygiene and credential risks across hybrid identity systems
This allows for proactive Active Directory security, helping teams prevent attacks tied to password reuse and credential leaks.
Why is Password Hash Analysis important?
MFA Doesn’t Stop Credential Stuffing-Especially for Service Accounts
Many organizations rely on Multi-Factor Authentication (MFA) to protect user identities. But MFA isn’t a complete defense, especially when it comes to service accounts. These non-human accounts:
- Usually don’t support MFA
- Often use static passwords that go unchanged for years
- Frequently hold elevated or domain-level privileges
- Are excluded from regular security reviews
- Are therefore ideal targets for credential stuffing attacks and a major blind spot in hybrid Active Directory environments.

Real-World Breaches Power Credential Stuffing Campaigns
Credential stuffing relies on real usernames and passwords exposed in previous data breaches. Attackers compile massive lists and automate login attempts across platforms like Microsoft 365, VPNs, and Active Directory.
Recent breach data highlights the scale of the problem:
- RockYou2024: The largest password leak in history. This file includes 9.9 billion unique passwords, aggregated from over 4,000 data breaches.
- 23andMe Breach (2023): Attackers used credentials from earlier breaches to take over 14,000 accounts accessing personal and genetic data for 6.9 million users through credential stuffing.
- Cybernews Analysis (2024): More than 19 billion passwords analyzed. Only 6% were unique—the rest were reused. The password “123456” appeared over 338 million times.
With usernames often tied to Microsoft 365 email addresses, which are publicly available on LinkedIn and company websites, attackers don’t need to guess, only test.

Strengthen Your AD Security Against Credential-Based Threats
Credential stuffing doesn’t require sophisticated malware, it only needs reused credentials. MFA doesn’t protect service accounts. Traditional monitoring doesn’t catch password reuse. And breach data continues to grow every day.
With Cayosoft Guardian’s new breached password detection, you gain real-time insights into password risk and Active Directory exposure across both human and non-human accounts.

FAQs
Absolutely. Cayosoft Guardian never decrypts or exposes actual passwords. Instead, it securely compares password hashes using industry-standard cryptographic methods, making it a compliant and non-invasive way to detect credential exposure.
