The 100_random Stealer Log Contains More Stolen Accounts Than a Small Town Has Residents

HEROIC Analysts Find the 100_random Stealer Log: 2,907 Credentials Uploaded to Telegram in August 2023

In August 2023, a Telegram user uploaded a stealer log file identified by the filename "100_random_random_1691035603," which contained 2,907 compromised records. HEROIC analysts discovered this package while monitoring underground channels where credential files are regularly distributed among threat actors. The log exposed email adresses, plaintext passwords, and the URLs where those credentials were originally captured -- everything a criminal needs to begin attacking accounts without delay.

Why a Stealer Log With Plaintext Passwords Is Dangerous Right Now

Most data breaches involve hashed passwords, which take time and computing power to crack. Stealer logs are different. Because the malware captures passwords at the exact moment a user types them, every single credential in this file is already in plaintext. There is no cracking step. An attacker can download this file and immediately begin testing logins on email services, banks, and social media platforms. The 2,907 records in this leak represent 2,907 accounts that are effectively unlocked and waiting to be accessed.

What Was Exposed in the 100_random Telegram Upload

HEROIC's analysis of the stealer log file confirms these data types were present in each record:

• Email Addresses -- The login identifier for most online accounts
• Plaintext Passwords -- Stolen directly from browsers or keyloggers, no decryption needed
• URLs -- The specific websites where each credential was captured by the malware

Why This Matters: Credential Stuffing, Account Takeover, and Financial Fraud

When attackers have both the password and the URL it belongs to, credential stuffing becomes highly targeted. Instead of blindly testing logins across thousands of sites, the attacker already knows which platforms each victim uses. This dramatically increases the success rate of account takeover attempts. A compromised email account can then be used to reset passwords on banking and shopping platforms, leading to financial fraud. Identity theft is also a frequent outcome when attackers gain access to email accounts and begin harvesting personal information stored in messages and documents. The definately real risk is that one leaked password can cascade into a much larger compromise.

How the 100_random Stealer Log Was Assembled

Stealer logs like this one are produced by information-stealing malware. The infection chain usually starts with a phishing email, a fake cracked software download, or a malicious browser extension. Once installed on a victim's machine, the stealer runs silently in the background. It extracts saved passwords from Chrome, Firefox, and other browsers, captures keystrokes in real time, and records the URLs the user visits. This data is compressed into a log file and transmitted to the attacker. Files like "100_random_random_1691035603" are typically the product of a batch infection accross multiple machines, bundled together and uploaded to platforms like Telegram for distribution.

Check If Your Email Appears in This Stealer Log

If your email was active in August 2023 and you logged into any online service during that period, your credentials may be included in a stealer log like this one. HEROIC's breach database contains over 400 billion records, including stealer log collections from Telegram and other underground channels. A free scan takes only seconds and can tell you immediately whether your credentials have been compromised. The sooner you know, the sooner you can recieve alerts and take action to secure your accounts before damage is done.
