Password Reusers Beware: The prdscloud 6 Breach Dumped 1,144 Accounts

In August 2023, HEROIC analysts identified the sixth and largest batch in the prdscloud stealer log series being shared on Telegram. Designated prdscloud 6, this file contained 1,144 records with email addresses, plaintext passwords, and service URLs harvested from infected devices. It was distributed freely, meaning any threat actor with access to the right Telegram channel could download 1,144 ready-to-use credentials at no cost. This is the largest single release in the prdscloud series identified to date.

Why the prdscloud 6 Stealer Log Is Dangerous

At 1,144 records, prdscloud 6 is not a small sample. It is a substantial batch of credentials covering a broad range of individuals and services. Every password in the file is stored in plaintext, meaning there is no technical barrier between an attacker and a working login. The included URLs remove the guesswork about which services to target. For anyone whose credentials appear in this file, the risk is not hypothetical. Attackers who download this log can begin attempting account access within minutes.

What Was Exposed in the prdscloud 6 Stealer Log

• Email addresses
• Plaintext passwords (no hashing or encryption, immediately usable)
• URLs (identifying specific services where credentials were captured)
• API host endpoints

Why This Matters

The scale of this log makes it a particularly useful resource for credential stuffing attacks. In a credential stuffing attack, criminals take a list of stolen email and password pairs and test them automatically across dozens of websites and apps. With 1,144 complete sets of email, password, and target URL, the prdscloud 6 log is well suited to that kind of automated abuse. People who reuse the same password across multiple accounts face the greatest risk. A single match in this file could cascade into account takeovers across email, banking, social media, and workplace systems.

How Stealer Logs Like prdscloud 6 Work

Stealer logs like prdscloud 6 do not come from a company being hacked. They come from malware running on individual devices. Infostealer malware spreads through phishing emails, fake software downloads, and malicious browser extensions. Once installed on a device, it harvests saved browser passwords, captures active session cookies, and records keystrokes on login pages. The collected data is packaged into a structured file and sent to the attacker. The prdscloud series shows how a sustained infostealer operation builds up its dataset over time, releasing batches in waves as new devices are infected and credentials are harvested.
