14,061 Records from 364PCSGIFTOTTOHELP Leaked in Stealer Log Attack

On December 28, 2023, a Telegram user posted a stealer log file labeled "364PCSGIFTOTTOHELP" containing 14,061 records. The file included email adresses, plaintext passwords, and URLs taken from infected devices, and was made freely available to anyone who could access the channel. This kind of public release means the data spread quickly with no way to contain it after the fact.

Why This Is Dangerous

Stealer log files like this one bypass traditional security controls entirely because the data is recieved straight from the victim's machine. By the time a log file appears on Telegram, the credentials have already been verified as real and working on actual devices, which makes them significantly more dangerous than a typical leaked database.

With 14,061 records exposed, attackers have a large pool of credentials to test against email services, banking platforms, and corporate logins. Automated credential stuffing tools can run through thousands of login attempts per hour, meaning these credentials could be actively abused within hours of the file being posted.

The public nature of the Telegram upload is also important. Unlike private sales on dark web forums, a public post gets downloaded, copied, and redistributed. Once data is out this way, it's essentially permanent and impossible to fully retract.

What Was Exposed

• Email addresses associated with active user accounts
• Plaintext passwords with no hashing or encryption protection
• URLs revealing which websites and apps were in use on infected devices
• API host data indicating connections to application back-ends
• Endpoint identifiers from the compromised machines
• Browser-harvested credentials from saved login data
• Potential session cookie data from active authenticated sessions
• Login patterns that could reveal high-value target services

Why This Matters

Fourteen thousand compromised records is not a small incident. At that scale, the dataset almost certainly includes a mix of personal and professional email accounts, which means workplace systems and corporate networks are also at risk, not just individual users. A single compromised work email can give an attacker a foothold into internal tools, file systems, and communication channels.

The timing of this leak, December 2023, also matters. Many people don't check their accounts closely during the holiday season, and attackers know this. A Telegram upload at that time of year is deliberate, targeting a window when victims are less likely to notice suspicious activity until significant damage has already occured.

How Stealer Log Works

Infostealer malware is one of the most common tools used to build credential databases like this one. It spreads through phishing campaigns, fake software installers, and malicious browser extensions. Once it runs on a device, it scans for and extracts saved passwords from all major browsers, grabs active session cookies, and logs keystrokes to capture anything not stored locally.

The malware then compresses all collected data into a structured log and sends it to an attacker-controlled server. From there, the operator sorts the logs by quality or region and either sells them privately or distributes them on public channels like Telegram. Files shared publicly tend to be part of a reputation-building strategy or a way to flood the market after the best records have already been sold seperately.

The whole process from infection to log upload can happen in a matter of days, which is why checking your email against known breach datasets regularly is important. Waiting for a notification means you may already be behind the attackers by the time you find out.

Check If You Were Affected

The 364PCSGIFTOTTOHELP stealer log has been circulating since late December 2023, and its data may still be in active use by attackers. HEROIC's free breach checker at heroic.com lets you search your email address against a large database of known breach and stealer log records. Check now, and if your information shows up, change your passwords right away and turn on two-factor authentication on every account you can.
