Credential Holders Beware: The APRIL 2 – 1120 LOGS Leak Dumped 18K Stolen Passwords

HEROIC analysts reviewed a stealer log file uploaded to a public Telegram channel on December 26, 2023, carrying the label "APRIL 2 - 1120 LOGS." The dataset contains 18,535 records collected from compromised endpoints, each exposing an email address, a plaintext password, and associated URLs from API hosts and web services the victims were actively using. The log structure is consistent with credential-harvesting malware output -- the kind that silently copies passwords off infected devices and ships them to a remote server before most victims ever notice anything is wrong.

Endpoint Users Beware: The APRIL 2 - 1120 LOGS Leak Targets Everyday Credentials

The people most at risk from this particular leak are everyday internet users whose devices were silently infected by infostealer malware. With 18,535 sets of plaintext email and password credentials now in the public domain, anyone who downloaded this log from Telegram can immediately attempt to access the accounts listed. The included URLs make the job even easier for attackers -- they show exactly which websites and services each victim was using, removing the need for guesswork. Remote workers, freelancers, and small business employees are frequently targeted by this type of malware because their personal devices often lack the security controls found on corporate networks. If any of the affected users were logging in to workplace systems from infected personal machines, the risk extends beyond individual accounts to organizational data and internal systems.

What Was Exposed in the APRIL 2 - 1120 LOGS Leak

• Email Addresses
• Plaintext Passwords
• URLs (API hosts, login portals, and web services accessed from infected devices)

Why Plaintext Passwords in a Stealer Log Are a Compounding Risk

Plaintext passwords are the most dangerous form of leaked credential because they require zero additional effort to use. No cracking, no decryption -- an attacker just copies the email and password into a login form and tries it. Because the majority of internet users reuse passwords across multiple platforms, a single working credential from this log can unlock email accounts, bank portals, social media profiles, and workplace logins all at once. Attackers often start with the email account itself, since controlling someone's inbox means they can trigger password resets on every other service that sends reset links by email. From there, financial fraud, identity theft, and even corporate network compromise become realistic outcomes. Victims in this dataset may not have realised anything went wrong until weeks or months after the December 2023 upload, giving attackers a long window to cause damage without detection.

How Stealer Log Malware Works

Infostealer malware is a category of malicious software designed specifically to harvest credentials from an infected device without the user noticing. It typically spreads through phishing emails with malicious attachments, fake software installers, cracked applications, or drive-by downloads on compromised websites. Once it takes hold, it scans the device for saved passwords stored in web browsers, extracts session cookies that allow bypassing login pages entirely, and captures credentials from email clients and messaging tools. Everything it finds gets bundled into a log file -- like the one labeled "APRIL 2 - 1120 LOGS" -- and silently sent back to a server controled by the attacker. From there, the attacker may sell the log, share it freely on Telegram, or use the credentials directly in targeted attacks. The December 2023 upload suggests this data sat in criminal hands for some time before being made public, which means it may have already been used for account takeover before anyone outside that circle was aware of the leak.

Check If Your Accounts Were Caught in This Telegram Stealer Log

If you think your device may have been infected or your email could be among the 18,535 records in this leak, HEROIC's free breach scanner at heroic.com can help you find out. HEROIC maintains a database of over 400 billion compromised records sourced from stealer logs, dark web dumps, and major breach compilations. A simple search by email address will show you whether your credentials have appeard in any known leaks, so you can change passwords and lock down accounts before an attacker gets the chance to do real damage.
