NO 3.24 Leak Means 3,993 Accounts Are Ready to Steal

A stealer log file identified as NO 3.24 was uploaded to a Telegram channel in April 2023 and has since circulated among threat actors and data traders. HEROIC analysts confirmed the file contains 3,993 records, each linking an email address to a plaintext password and the URL of the service where the credentials were used.

While 3,993 records may seem modest compared to larger breaches, the nature of this data makes every single record immediately exploitable. These are not hashed or encrypted passwords that require effort to decode. They are ready-made keys to real accounts, sitting in a file that anyone on Telegram can download.

Why Plaintext Passwords Make These Accounts Instant Targets

Every password in the NO 3.24 file is stored in plaintext, exactly as the victim typed it. An attacker does not need to run cracking software or invest computing resources to use these credentials. The path from downloading the file to logging into a victim's account takes seconds.

This level of exposure is the digital equivalent of leaving your house key taped to the front door. There is no lock to pick, no code to guess, and no barrier between the attacker and the account. For the 3,993 people in this file, their credentials have been freely available since the moment the dump was posted.

What Was Exposed in the NO 3.24 Dump

• Email Addresses — The login identifiers for each compromised account, which also serve as a starting point for phishing and social engineering attacks.
• Plaintext Passwords — Unprotected, human-readable passwords extracted from victims' devices by malware, usable without any additional processing.
• URLs — The web addresses of login pages where the credentials were captured, providing attackers a direct map of which services to breach first.

Why Even a Small Leak Carries Outsized Risk

The danger of a credential dump is not measured solely by its size. A file with 3,993 high-quality, plaintext credential sets can be more valuable to an attacker than a million hashed passwords. Every record in the NO 3.24 file is immediately actionable, and the URLs tell attackers exactly where to use them.

Password reuse amplifies the threat dramatically. If even a fraction of these victims used the same password on other services, attackers can pivot from a compromised streaming account to a banking portal, an email inbox, or a corporate VPN. Automated credential stuffing tools make this pivot trivial, testing thousands of login combinations per minute across dozens of platforms.

Smaller dumps also attract less public attention, which works in the attacker's favor. Victims are less likely to hear about the breach and change their passwords, leaving a longer window of opportunity for exploitation.

How Stealer Logs Supply a Steady Stream of Fresh Credentials

The NO 3.24 file is a product of infostealer malware, a category of threats designed to silently harvest credentials from infected devices. These programs typically spread through phishing emails with malicious attachments, fake software download sites, and compromised advertisements on legitimate websites.

Once running on a victim's machine, an infostealer extracts saved passwords from every browser installed, captures credentials from email clients and FTP applications, and records keystrokes during active login sessions. The collected data is structured into log files and sent to a remote server controlled by the attacker.

These individual logs are then aggregated, packaged into compilations like NO 3.24, and distributed on Telegram or sold on dark web marketplaces. The pipeline runs continuously, with new victims feeding fresh data into the system every day.

Check If Your Credentials Appear in This Leak

The NO 3.24 stealer log has been added to the HEROIC breach database. Use HEROIC's free breach scanner to check whether your email address or password appears among more than 400 billion indexed records from this and thousands of other known data breaches.

If your information appears in the results, change your password on every account that shared the compromised credential. Secure your email account first, as it is the gateway to resetting passwords on all your other services. Activate two-factor authentication wherever available, and adopt a password manager to ensure every account has a unique, strong password going forward.
