The OCTOBER 17 – 1003 LOGS Dump Contains 22,592 Stolen Credentials

HEROIC analysts documented the OCTOBER 17 - 1003 LOGS stealer dump after spotting it on a Telegram channel in October 2023. The file contained 22,592 records pulled from what appears to be over 1,000 individual infected machines. Each record includes an email address, a plaintext password, and a URL pointing to the service or system where those credentials were stored. The naming convention of the file, referencing 1,003 individual log files, indicates this was a curated compilation rather than a single infection, meaning the attacker gathered output from a large number of compromised endpoints before bundling and distributing the data on Telegram.

Why the Scale of the OCTOBER 17 1003 LOGS Dump Makes It Particularly Dangerous

A dump sourced from more than 1,000 infected machines means the credentials inside came from many different individuals, companies, and systems. This is not a breach of one organization. It is a horizontal slice across many organizations and personal accounts, all collected through the same type of malware campaign.

Because the passwords are stored in plaintext, each record in this dump is immediatly usable. An attacker does not need to invest time in cracking. They can begin attempting logins against the associated URLs and any other platform where the victim may have reused their password. With 22,592 records available, even a low success rate translates into hundreds of compromised accounts.

What Was Exposed in the OCTOBER 17 - 1003 LOGS File

• Email addresses from victims across multiple organizations and services
• Plaintext passwords stored with no hashing or encryption
• URLs identifying the specific services and systems each credential belongs to
• 22,592 total records aggregated from 1,003 individual log files

Why This Matters: What Attackers Can Do With 22,000 Plaintext Passwords

Credential stuffing tools can test thousands of username and password combinations per minute across multiple platforms simultaneously. With 22,592 working credentials, an attacker can automate account takeover attempts against email providers, banking platforms, corporate login portals, and cloud services with minimal effort.

Beyond automated attacks, this data is valuable for targeted intrusions. An attacker who identifies a corporate email address in the dump can use the associated password to attempt access to that company's internal systems. Financial fraud, identity theft, and unauthorized data access all become realistic outcomes. The presence of URLs in the dump means attackers already know where each credential is likely to work, removing the guesswork entirely.

How Stealer Log Compilations Like This One Are Built and Distributed

Infostealer malware operates silently on infected machines, harvesting saved passwords, browser cookies, and system credentials. The output of each infection is a structured log file. Cybercriminals then collect these individual logs, sometimes purchasing them from other actors, and compile them into larger archives for distribution on Telegram and dark web marketplaces.

The OCTOBER 17 - 1003 LOGS dump is a clear example of this process. The file name references 1,003 seperate log files merged into one archive. The October 17 date suggests the collection period ended around that date before the full package was uploaded on October 25. Victims whose machines were infected at any point during that window could find their credentials in this dump, even if they changed their password afterward on a different device.
