Researchers Track the October 17 – 1002 LOGS Dump to 30,085 Stolen Credentials on Telegram

HEROIC researchers identified a stealer log file on October 25, 2023, surfacing on a public Telegram channel under the file label "OCTOBER 17 - 1002 LOGS." The file held 30,085 records collected by infostealer malware from infected endpoints, covering email addresses, plaintext passwords, and URLs tied to the services those credentials accessed. What researchers noted beyond the raw count was the combination of credential types and associated endpoint data, a pairing that lets attackers move directly from credential theft to system access without additional reconnaissance. The log was posted publicly, meaning it was accessible to any Telegram user at the time of upload.

Why the October 17 - 1002 LOGS Dump Signals a Broader Threat Pattern

Researchers monitoring Telegram channels for stealer log activity have noted that dumps like this one are rarely the work of a single attacker. These logs aggregate data from dozens or hundreds of infected machines, each silently sending back credentials to a central collection point. The presence of both passwords and the URLs where those passwords were used tells researchers that the malware was configured to capture context alongside credentials, making the data far more actionable for buyers or operators who download and exploit these files after they are posted.

What Was Exposed in the October 17 - 1002 LOGS File

• Email addresses from accounts on infected devices
• Plaintext passwords with no encryption or hashing protection
• URLs showing which services and internal systems the credentials belong to
• Endpoint and API host data from compromised machines
• 30,085 total records sourced from stealer malware infections

Why Plaintext Passwords and System URLs Are a Dangerous Combination

Researchers consistently flag plaintext password leaks as the most immediately exploitable type of credential exposure. There is no cracking step required. An attacker downloads the log, runs the email and password pairs through an automated tool, and within hours has a list of accounts that are successfully compromised. When system URLs are included, those same tools can target the exact services the credentials were harvested from, increasing the succes rate of attacks significantly. Identity theft, account takeover, financial fraud, and lateral network movement are all real consequences of this kind of data being loose on Telegram.

How Infostealer Malware Creates These Log Files

Infostealer malware, also called credential stealers, are programs designed to run quietly in the background on an infected device. They scan browser storage for saved passwords, grab cookies and session tokens, pull credentials from email clients and productivity tools, and record the URLs associated with every credential they find. Once the collection is complete, the malware sends the packaged log file to a remote server or directly to a Telegram channel controlled by the operator. The victim's device shows no obvious signs of infection, and many people only discover their data was stolen months later when they see unfamiliar logins or recieve account compromise alerts.
