Your Passwords May Be in the “2 4” Telegram Stealer Log Breach

Telegram Stealer Log "2 4" Breach: 19,599 Credentials Leaked in the Open

In April 2023, a Telegram user operating under the handle "2 4" shared a stealer log collection containing 19,599 credential records on a public channel. The dataset was harvested from malware-infected devices and includes email addresses, plaintext passwords, and the login URLs where those credentials were actively used. This breach has been circulating in underground channels for over three years, giving attackers ample time to exploit every record in the collection.

Why This Stealer Log Puts You at Direct Risk

If your device was infected by infostealer malware at any point before April 2023, your credentials may already be in the hands of cybercriminals. The "2 4" stealer log is particullarly dangerous because it contains passwords in plaintext, meaning there is zero barrier between an attacker and your accounts. Unlike breaches where passwords are hashed and must be cracked over time, every credential in this dataset was ready to use from the moment it was uploaded. Attackers who obtained this data have had years to test these login combinations against banking sites, email providers, and corporate portals.

What Was Exposed in the "2 4" Stealer Log

Compromised Data Fields

• Email Addresses - Personal and work email accounts linked to saved browser login credentials across dozens of online platforms
• Plaintext Passwords - Fully readable passwords extracted from victims' browsers with no encryption or hashing applied
• URLs - The exact website login pages associated with each credential pair, providing attackers a complete roadmap for account takeovers

Why You Should Be Concerned Right Now

Stealer log data ages differently than traditional breach data. Because these credentials come directly from real browsers on real devices, they often include passwords for services that victims use daily. Even if you have changed some passwords since 2023, attackers use stealer logs to identify patterns in how you create passwords, which services you use, and which email addresses you rely on. This inteligence makes targeted phishing and social engineering attacks far more effective. Corporate security teams face additional risks, as employee credentials found in stealer logs frequently serve as the initial foothold for ransomware operators and business email compromise schemes.

How Stealer Log Attacks Work

Infostealer malware is typically delivered through phishing emails, pirated software, fake browser updates, or malicious advertisements. Once installed on a victim's device, the malware silently extracts saved passwords, session cookies, autofill data, and browser tokens from Chrome, Firefox, Edge, and other applications. The stolen information is structured into log files and exfiltrated to command-and-control servers. Threat actors then compile these individual logs into bulk collections and distribute them through Telegram groups, dark web forums, and underground marketplaces. The "2 4" collection represents credential data harvested from thousands of seperate compromised endpoints.

Check If Your Accounts Were Compromised

With 19,599 records in this stealer log and years of circulation in criminal channels, your data may have already been exploited without your knowledge. HEROIC's data breach scanner searches over 400 billion compromised records, including stealer log collections like the "2 4" dump. Run a free scan with your email address to discover if your credentials were exposed and take immediate action to change passwords and enable two-factor authentication on all affected accounts.
