Analysts Trace STONE ISLAND FREE LOGS to 4,777 Stolen Credentials

In June 2023, a Telegram user shared a stealer log collection labeled STONE ISLAND FREE LOGS, exposing 4,777 records of compromised user credentials harvested from infected endpoints. HEROIC analysts identified and verified this dataset during routine dark web surveillance, confirming the leaked information included email addresses, plaintext passwords, and URLs from real victim sessions. These records have now been available to criminals for nearly three years, giving attackers ample time to exploit the exposed data across credential stuffing campaigns, phishing operations, and direct account takeover attempts. Long-standing leaks like this are among the most insidious because most victims never recieve any notification and may still be using the same compromised passwords today.

Why This Is Dangerous

Long-standing data leaks are particulary treacherous because victims may have never changed affected passwords, leaving accounts vulnerable for years. Criminals often revisit older datasets when credential stuffing new targets, knowing that many users still haven't acted on breaches from 2023 or earlier. Plaintext passwords in this collection require zero technical effort to exploit -- any criminal with access to this dataset can attempt to log in to your accounts imediately. The combination of a verified email address and its associated plaintext password is the most dangerous credential pair that can appear in a breach dataset.

What Was Exposed

• Email Addresses -- Your email address is the linchpin of your online presence, used to verify identity and reset access to every service you use. It is also the primary vector for follow-on phishing attacks after initial credential theft.
• Plaintext Passwords -- These passwords require no decryption and are ready to use immediately, making them the most dangerous form of exposed credential data. Password reuse means a single stolen password can open many accounts.
• URLs -- The included site URLs and endpoint data map out which online services and platforms the victims were using at the time of compromise, enabling targeted attacks against the most valuable accounts.

Why This Matters

Credential stuffing attacks using data from this breach may have already been running for nearly three years against targets like banking portals, social media, and streaming services. Attackers purchase or freely download datasets like this and feed them into automated bots that test each pair across thousands of sites simultaneously. A single matching password on a financial account can result in drained funds, fraudulent transfers, or identity theft. Victims who recieved no notification of this breach are especially at risk -- this is precisely why HEROIC tracks datasets like STONE ISLAND FREE LOGS as part of its 400 billion record database.

How Stealer Log Works

Stealer malware is a category of malicious software designed specifically to extract credentials from browsers, password managers, and active sessions on a victim's device. The malware typically spreads via fake software cracks, phishing links, or malicious email attachments. Once installed, it silently sweeps the device for login data and transmits it to the attacker's server, where it is compiled into structured log files containing email, password, and URL fields for each captured login. These logs are then redistributed through Telegram channels -- as occurred here with STONE ISLAND FREE LOGS -- often shared for free as a way to build credibility within criminal communities.

Check If You Are Affected

HEROIC's free dark web scanner searches more than 400 billion records, including legacy stealer log datasets dating back to 2023 and earlier. Visit heroic.com to scan your email for free and determine if your credentials appear in the STONE ISLAND FREE LOGS breach or any other known leak. Acting now -- even years after the initial exposure -- can help you change compromised passwords and secure accounts before further damage is done.
