The 100_random_random_1691212409 Stealer Log Contains More Stolen Logins Than a Small Town Has Residents

What HEROIC Analysts Found in the 100_random_random_1691212409 Stealer Log

In August 2023, HEROIC analysts catalogued a stealer log file shared on Telegram under the filename 100_random_random_1691212409. The file contained 2,366 compromised records, each one harvested from a real person's device by information-stealing malware. The data included email addresses, plaintext passwords, and the URLs of the services those victims were authenticated to at the time of infection.

The filename of this log suggests it was generated automatically by a stealer tool using a timestamp-based naming convention, a common practice among threat actors who distribute large volumes of log files through Telegram. Despite the generic name, each of the 2,366 records represents a real stolen identity with real consequences.

Why Plaintext Passwords in the 100_random_random_1691212409 Log Are a Direct Threat

Plaintext passwords are the most dangerous form of credential data because they require no additional processing to use. An attacker with access to this log file can take any of the 2,366 records and immediately attempt to log in using the captured email, password, and URL combination. Nothing separates them from the target account except perhaps a second factor that many users have not enabled.

These credentials can be used in automated credential stuffing tools that test the same email and password pair across hundreds of other websites simultaneously. If a victim used the same password anywhere else, even once, those accounts become vulnerable the moment this log enters circulation.

What Was Exposed in the 100_random_random_1691212409 Stealer Log

• Email addresses (primary account identifiers across most online platforms)
• Plaintext passwords (fully readable, requiring no decryption or cracking)
• URLs (identifying the specific websites and services each credential belonged to)

Why the 100_random_random_1691212409 Log Connects to Broader Account Takeover Risk

Even a stealer log with a few thousand records carries significent downstream risk when the stolen data includes plaintext passwords. Account takeover fraud starts the moment an attacker successfully logs in. From a compromised email account, they can pivot to banking, shopping, and social media platforms using password reset flows. From a compromised workplace account, they may gain acces to internal documents, client data, and financial systems.

Identity theft is another real outcome. Personal information stored in email accounts, cloud storage, or connected services can be harvested and used to open fraudulent credit lines, file false tax returns, or impersonate the victim in high-value scams. The fact that this log was distributed on Telegram means it was acessed by an unknown number of threat actors, each capable of acting on the data independently.

With only 2,366 records, this is a smaller log, but size is irrelevent to the individual who finds their credentials inside it.

How the 100_random_random_1691212409 File Was Created by a Stealer Tool

The naming convention of this file, using a numeric suffix that corresponds to a Unix timestamp, is a hallmark of automated stealer log generation. Information stealer malware often runs on infrastructure that automatically packages harvested credentials into log files at regular intervals, naming each one with a timestamp to track when the data was collected.

These stealers spread through phishing emails, malicious software downloads, and drive-by browser exploits. Once installed, they harvest saved browser passwords, intercepted login events, and session cookies, then transmit the data back to an operator-controlled server. The resulting files are sorted, named, and distributed through Telegram for sale or free redistribution.

Victims typically have no warning their device was compromised until they experience unauthorized account access.
