Naz.API Leak Exposes 70.8 M Email Addresses and Passwords
What Happened — In September 2023, more than 100 GB of stealer logs and credential‑stuffing lists labeled “Naz.API” were posted to a popular hacking forum. The dump contained 71 million unique email addresses paired with 100 million plaintext passwords, along with service identifiers for many of the credentials.
Why It Matters for Trust & Control Assurance
- Continuous credential‑monitoring programs are designed to detect exactly this type of mass exposure and provide auditable evidence that compromised passwords are being revoked.
- Strong identity‑and‑access‑control policies (password complexity, MFA, credential rotation) are core control objectives that map to dozens of framework requirements, giving you a single defensible control signal across ISO 27001, NIST CSF 2.0, and others.
- Demonstrating timely remediation (forced resets, MFA rollout) supplies the documentation needed for audit readiness and reduces downstream breach risk for any downstream services that relied on the same credentials.
Who Is Affected — SaaS platforms, API providers, and any organization whose users may have reused Naz.API credentials (technology, finance, retail, etc.).
Recommended Actions
- Immediately force password resets for any accounts that may have used the exposed credentials.
- Enforce multi‑factor authentication (MFA) for all user logins.
- Deploy credential‑monitoring tools that alert on compromised passwords in real time.
- Document password‑policy enforcement and MFA adoption as part of your continuous control‑assurance evidence. Source: [Have I Been Pwned – Naz.API breach]
Technical Notes
- Data type: email addresses and plaintext passwords.
- No specific vulnerability disclosed; the breach appears to stem from credential‑stuffing activity and unauthorized data exfiltration. Source: [HIBP breach page]
