Telegram Threat Actor Exposes APRIL 9 – 1005 LOGS uploaded by a Telegram User Data: 13,674 Records at Risk

On December 26th, 2023, a Telegram threat actor published a stealer log collection labeled "APRIL 9 - 1005 LOGS," putting 13,674 user records into the open. The exposed data includes plaintext passwords, email addresses, and URLs, all harvested from compromised devices through infostealer malware. Leaks like this one are particularly troubling because the credentials are usually still active when they first surface, giving attackers a narrow but very real opportunity to do serious damage before anyone is notified.

Why This Is Dangerous

This is not a theoretical risk. Plaintext passwords in a stealer log mean attackers have working credentials they can test immediately, without needing to crack anything. When someone recieved malware on their device, the stealer captured everything stored locally, often without triggering any security alerts.

The URLs included in this dataset indicate which services or platforms were accessed from the infected machines. That context lets attackers know exactly where to use the stolen credentials, rather than guessing. It turns a generic credential dump into a targeted attack toolkit.

With 13,674 records distributed freely on Telegram, the data quickly spreads across multiple communities. Threat actors share and redistribute these logs, so the exposure does not end with the original upload.

What Was Exposed

• Email addresses used to log in to various services
• Plaintext passwords harvested directly from infected devices
• URLs showing which sites and services were accessed
• API host endpoints and authentication paths
• Browser autofill and saved credential data
• Session identifiers captured at time of infection
• Device or environment context from the infected endpoints

Why This Matters

A leak of 13,674 records is significant. Password reuse means one compromised credential can unlock email, banking, work accounts, and more. Attackers run automated tools against dozens of platforms at once, so even if you only used the same password on a couple of sites, the risk multiplies quickly.

The fact that this was uploaded publicly on Telegram rather than sold privately means adress verification is nearly impossible. The data has likely been downloaded and redistributed many times over since December 2023, making containment extremely difficult at this stage.

How Stealer Log Works

Stealer log breaches start on the victim's own device, not on a company's server. Infostealer malware, often distributed through phishing links, cracked software downloads, or malicious browser extensions, installs itself silently and begins collecting credentials right away.

Once active, the malware sweeps through browser password managers, saved form data, and active sessions. It bundles everything into a structured log file and sends that file back to the attacker's server. The entire process can occure in minutes, well before any antivirus scan catches it.

From there, the logs are sorted by value, packaged into collections like the APRIL 9 set, and distributed on Telegram channels or sold on dark web forums. Each log file represents a fully compromised device, with everything the user typed or saved potentially captured.

Check If You Were Affected

If your email address or password was among the 13,674 records in this Telegram leak, your accounts may already be at risk. Run a free check at heroic.com using HEROIC's breach checker to see if your credentials appeared in this or any other known data leak, and update your passwords right away.
