Your APRIL 30 – 1176 LOGS uploaded by a Telegram User Data May Be at Risk: Here’s What You Need to Know

In December 2023, a Telegram user uploaded a stealer log file to a public channel, releasing 17,259 records from compromised endpoints in the United States. The dataset, labeled "APRIL 30 - 1176 LOGS," contains email addresses, plaintext passwords, and URLs collected from infected machines. This is one of the larger stealer log releases we've seen, and if your credentials were among those captured, they've been freely accessable to bad actors for some time now.

Why This Is Dangerous

At 17,259 records, this is a substantial credential dump. The sheer volume means the malware campaign behind this log was either running for an extended period or had a very high infection rate across a large number of devices. Either way, the result is a dataset large enough to fuel a serious credential stuffing operation targeting dozens of popular platforms simultaneously.

The log was shared on Telegram, which requires no account verification to join channels and allows files to be downloaded by anyone. This means from the moment it was uploaded on December 26, 2023, the data has been freely available. Anyone with internet access could have downloaded it, and many likely did.

The presence of plaintext passwords is the most immediate concern. There is no decryption step, no hash cracking, no technical barrier whatsoever. The credentials are ready to use as-is, which makes this type of breach especially dangerous compared to leaks involving hashed passwords.

What Was Exposed

• Email addresses from a wide range of personal and professional accounts
• Plaintext passwords captured directly from infected user devices
• URLs identifying the websites and services associated with each credential
• API host information from backend endpoints accessed on compromised machines
• Browser-stored login credentials across multiple web platforms
• Session data and cookies from active authenticated sessions
• Endpoint metadata identifying the compromised devices themselves

Why This Matters

With 17,259 records in circulation since late 2023, this data has had over a year to be used, resold, and redistributed across criminal networks. Even if attackers haven't used your specific credentials yet, the window of risk is still wide open. Every day that passes without a password change is another day your accounts are potentially vulnerable to anyone who recieved a copy of this file.

Password reuse amplifies the damage considerably. If the same password from a compromised endpoint is being used on your email, your bank account, or your work systems, a single leaked record can cascade into a full account takeover across multiple platforms. Attackers routinely run credential stuffing attacks against major services using exactly this kind of data.

How Stealer Log Works

Infostealer malware spreads through a variety of methods, including phishing emails with malicious attachments, fake software downloads, and trojanized versions of popular applications shared through unofficial channels. Once installed, the malware operates silently and begins cataloging credentials stored in web browsers, desktop applications, and system keystroke logs.

The data is packaged into a log file and exfiltrated to a remote server. These logs are then organised by the attacker and sometimes sorted by type, country, or service. Collections like "APRIL 30 - 1176 LOGS" often reflect the date of compilation or the number of infected machines involved, in this case possibly 1,176 infected endpoints contributing to the 17,259 total records.

Distribution on Telegram is a common final step in the stealer log pipeline. Some actors sell the logs, others share them for free to demonstrate capability or attract followers to paid channels. Either way, the end result is the same: your credentials are out there, sitting in a file that anyone can beleive is harmless to download and use.
