Your APRIL 4 Telegram Stealer Log Data May Be at Risk: Here’s What You Need to Know

In December 2023, a Telegram user shared a stealer log file labeled "APRIL 4 - 3429 LOGS," exposing 77,037 compromised records to anyone who happened to be watching the right channel. HEROIC analysts reviewing the file found that each record includes an email address, a plaintext password, and a URL identifying the associated service. This is one of the larger single uploads seen in this range, and the data was free to download the moment it went live.

Why This Is Dangerous

A dump of 77,000 plaintext credentials is not a minor incident. Attackers running automated credential stuffing tools can process tens of thousands of login attempts per hour, meaning active exploitation was almost certainly underway within days of this upload. What sets stealer logs apart from other breach types is that the credentials are captured fresh, straight from an infected device, with no hashing or encryption layer standing in the way.

With over 77,000 records, this single upload likely affected people across dozens of different services and platforms. Attackers do not need all 77,000 credentials to succeed. They only need one that opens the right door to something valuable.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated service URLs

Why This Matters

For the people in this dataset, the immediate concern is credential reuse. Most people use the same or similar passwords across multiple accounts, so if an attacker finds a working combination for one service, they will try it on email providers, banking apps, and work systems as well. One entry in this log file could cascade into a full account compromise across someone's entire digital life.

How Stealer Logs Work

Stealer malware finds its way onto devices through fake software downloads, pirated content, malicious email attachments, and compromised websites. Once installed, it works quickly, scanning the device's browser data for saved passwords and autofill entries, then sending that data back to the attacker.

Collected logs are often bundled together into large files, organized by date or batch number, which is exactly the pattern reflected in the "APRIL 4" naming here. The operator then either sells the file or, as happened in this case, distributes it freely through a public Telegram channel. Once a file like this is live, control over who accesses it is essentially gone, since it can be forwarded, downloaded, and redistributed an unlimited number of times.

Check If You Were Affected

With 77,037 records exposed in this single upload, the chances that someone you know was affected are fairly high. Use HEROIC's free breach checker at heroic.com to search your email address and find out if your credentials appeared in this breach or any other known leak.
