How prdscloud 12 Stealer Log Exposed 1,318 Records via Telegram

HEROIC analysts identified this stealer log exposure in August 2023, when a Telegram user uploaded a log file to a dark web sharing channel. The file contained 1,318 records harvested from compromised endpoints, including email addresses, plaintext passwords, and URLs belonging to users of cloud services linked to the prdscloud infrastructure. The logs appear to have been collected by infostealer malware running silently on victim machines before being packaged and distributed freely online.

Why This Stealer Log Dump Is Dangerous

When credentials and endpoint data are freely shared on Telegram, they spread rapidly across criminal networks. Attackers don't need any technical skill to weaponize this data -- the passwords are already in plaintext, ready to be tested across hundreds of popular websites within minutes. The free distribution model actually makes these logs more dangerous than sold data, because many threat actors obtain and act on them simultaneously.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (including API endpoints and cloud service hosts)

Why This Matters

Plaintext password leaks are among the most severe type of credential exposure. Unlike hashed passwords that require cracking, these can be used imediately for credential stuffing attacks against email providers, banking portals, and SaaS platforms. Victims often reuse the same password across multiple services, meaning a single compromised credential can cascade into full account takeover, identity theft, and financial fraud across dozens of platforms.

How Stealer Logs Work

Stealer logs are generated by infostealer malware -- malicious software that silently runs on a victim's computer after being installed through phishing emails, fake software downloads, or malvertising. Once active, the malware harvests saved browser passwords, session cookies, autofill data, and any credentials typed into forms. This data is then bundled into log files and sent to a command-and-control server. Threat actors collect these logs and frequently share them in Telegram channels or dark web forums, sometimes for free to build reputation or attract buyers for premium collections.
