The Datacloudspace Stealer Log Quietly Appeared on the Dark Web

In May 2023, a file appeared on Telegram with very little fanfare. It contained 10,971 records tied to datacloudspace, each one a real person's email addres, plaintext password, and the URL of the site where that password was used. No breach notification. No news coverage. Just a stealer log, quietly circulating among the people who know where to look.

Why This Is Dangerous

Stealer logs are built to be silent. The malware that creates them runs in the background, harvesting credentials without triggering alerts or antivirus warnings. By the time a log like this surfaces on Telegram, the data has often been in criminal hands for weeks or months. The victims almost never know their information was taken until accounts start failing or charges appear that they didn't make.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (the exact websites the credentials belong to)

Why This Matters

Plaintext passwords require no cracking. The moment someone downloads this log from Telegram, they have everything needed to log in to your accounts directly. Combined with the URLs showing which sites the credentials belong to, this data enables targeted account takeovers, credential stuffing campaigns, and phishing attacks. The longer this information circulates, the more people who have access to it. Years after a breach like this, the data is still being used.

How Stealer Log Breaches Work

Stealer log breaches don't start with a hacked server. They start with a compromised device. Malware, often delivered through phishing emails, cracked software, or malicious browser extensions, silently scans the infected machine for saved passwords, session cookies, and login credentails. It then packages that data into a log file and sends it back to the attacker. These logs are sold or freely distribted on dark web forums and messaging platforms like Telegram, where they're downloaded by anyone with access.
