Naz.API Data Breach (2023)
If you are a customer of Naz.API, here’s what’s now in circulation.
In September 2023, over 100GB of stealer logs and credential stuffing lists titled "Naz.API" was posted to a popular hacking forum. The incident contained a combination of email address and plain text password pairs alongside the service they were entered into, and standalone credential pairs obtained from unnamed sources. In total, the corpus of data included 71M unique email addresses and 100M unique passwords.

On September 20, 2023, 70.8 million email addresses and roughly 100 million plaintext passwords tied to the Naz.API corpus appeared in a public hacking forum. The collection, exceeding 100 GB, consists of stealer logs and credential-stuffing lists that pair addresses with passwords and the specific services where those credentials were used. Anyone whose email is among the 71 million unique addresses now faces immediate risk of account takeover wherever the same password was reused.
Reported Details from the Disclosure
The primary listing on Have I Been Pwned states that the Naz.API dataset combines two main types of material: logs from information-stealer malware and large credential-stuffing dictionaries. It contains email-password pairs that include the target service for each pair, plus standalone credential sets whose original sources are not identified. The disclosure does not specify which exact services were most heavily represented or name any particular malware family responsible for the initial theft. What is certain is the scale: more than 70.8 million affected users and a total volume that makes selective targeting straightforward for criminals.

Why This Matters for You and Your Family
If your email address is in the Naz.API dump, every account that shares those passwords is exposed. Criminals do not need sophisticated tools; they simply test the leaked pairs against banks, email providers, social media, shopping sites, and government portals. When a password has been reused across personal, work, and family accounts, one breach quickly becomes many. Children’s accounts, often secured with the same family passwords or slight variations, are especially vulnerable because parents rarely monitor them as closely as their own. The exposure is not theoretical. Credential pairs like these are sold and traded within hours of appearing in forums, turning yesterday’s unnoticed breach into today’s active compromise.
The Doxxing and Identity-Chain Risk
Plaintext passwords paired with emails create direct pathways to doxxing. Once an attacker logs into one service, they can harvest additional personal details—phone numbers, addresses, dates of birth, and linked accounts—then pivot to others. These identity chains grow rapidly: a gaming account leads to a parent’s email, which leads to a family photo repository, which reveals children’s names and schools. The Naz.API material, because it already maps emails to specific services, accelerates this chaining process. What begins as a credential leak can end with full identity exposure, harassment, or targeted scams against every member of a household.
What to Do
- Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup of Warden to remove what you can.
- Rotate every password that appears in the Naz.API corpus anywhere it has been reused and switch to unique, randomly generated passwords managed by a reputable password manager.
- Enable continuous DoxxScan monitoring across 13.1 billion+ breach records and more than 100 platforms so the next time your data surfaces it is caught within hours rather than months.
- Cover the entire household with DoxxScan family protection, which extends to dependents and children’s gaming accounts that often chain back to the same addresses and passwords.
- Let remediation specialists handle takedown requests across data brokers and exposed profiles while you focus on securing the accounts that matter most.
The Naz.API incident is a reminder that credential leaks continue to fuel the majority of account takeovers long after the initial posting. Acting quickly on exposed passwords and establishing ongoing visibility into new leaks is the only reliable defense for ordinary families. DoxxScan by GalaxyWarden delivers that visibility through continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and household coverage that includes children’s gaming accounts.

Each record is labeled: confirmed breach data, or an attacker’s claim no one has verified.
Leaked data cannot be deleted from the internet — anyone claiming otherwise is lying. Broker listings can be removed. We do the second, and show you exactly what to fix from the first.
