ReimannCloud 11-19 Leak Opens Door to 4,723 Account Takeovers

HEROIC discovered 4,723 records exposed in the ReimannCloud 11-19 stealer log breach on April 5, 2023. A Telegram user published the log file, packaging endpoint data, email accounts, API hosts, and plaintext passwords scraped from infected PCs.

Why This Stealer Log Is Dangerous

Each record in a stealer log is a ready-to-use recipe for account takeover. With plaintext passwords mapped to URLs, attackers skip the cracking stage entirely. Credential stuffing bots can exhaust every exposed login within hours.

What Was Exposed in ReimannCloud 11-19

• Login credentials (emails and plaintext passwords)
• Browser cookies and session tokens
• Autofill data including addresses and payment details
• Cryptocurrency wallet files and seed phrases
• System fingerprints and device information

4,723 victims had their browser vaults drained and distributed for free.

Why This Matters

Account takeovers ripple into password-reset attacks on email, which then cascade into banking, shopping, and social accounts. Victims often discover the compromise only after fraudulent charges or locked-out inboxes surface.

How a Stealer Log Like ReimannCloud 11-19 Works

Malware such as RedLine, Raccoon, or Lumma lands through pirated software, phishing lures, or malvertising. Once executed, it harvests browser-stored credentials, wallets, and cookies, packages them into a log, and uploads the archive to Telegram channels for resale or free distribution.
