13 AUGUST 126PCS OTTOFLOWGIFT 20240813211026 uploaded by a Telegram User

HEROIC analysts identified a stealer log file uploaded to a public Telegram channel in August 2024. The file, labeled "13 AUGUST 126PCS OTTOFLOWGIFT 20240813211026," was shared by an anonymous Telegram user and contained raw credential dumps harvested directly from compromised endpoints. The presence of plaintext passwords confirmed this was the output of infostealer malware, not a database breach or phishing campaign. A total of 166 records were exposed, each representing a distinct compromised device with associated email addresses, plaintext passwords, and URLs.

Why This Is Dangerous

Stealer log data is among the most actionable credential material available on cybercriminal marketplaces. Unlike hashed passwords that require cracking, these credentials are already in plaintext and ready for immediate use. Attackers who acquire this data can:

• Log directly into email accounts, banking portals, or workplace systems using the stolen credentials
• Use the exposed URLs to identify exactly which services the victims were using at the time of infection
• Pivot from personal accounts to corporate systems using the same credentials
• Sell individual credential sets on dark web markets for further exploitation

What Was Exposed

The following data types were confirmed in this stealer log:

• Email Addresses
• Plaintext Passwords
• URLs (API hosts and visited domains)

Why This Matters

Even 166 exposed records can cause significant harm. Stealer logs are frequently used as the starting point for credential stuffing attacks, where automated tools test the stolen email-password pairs across hundreds of popular websites. A single set of reused credentials can unlock banking accounts, cloud storage, corporate VPNs, and social media profiles. Identity theft and financial fraud follow quickly once an attacker gains a foothold. The public availability of this data on Telegram means it was accessible to any threat actor with a basic understanding of where to look.

How Stealer Logs Work

Infostealer malware is a category of malicious software designed to silently harvest credentials and sensitive data from an infected device. It is commonly distributed through phishing emails, trojanized software downloads, or malicious advertisements. Once installed, the malware scans the victim's browser saved passwords, session cookies, clipboard data, and local credential stores, then packages everything into a compressed log file. That log is transmitted back to the attacker's command-and-control server or dropped directly into a Telegram channel for immediate distribution. The victim typically has no idea their device is compromised until the credentials are already being used elsewhere.

Check If You Are Affected

If you believe your credentials may have been captured by infostealer malware, you should act immediately. HEROIC's free breach scanner checks your email address against a database of over 400 billion leaked records, including stealer log data like this.
