ReimannCloud’s April 5 Dump: 1,915 Stolen Logins

HEROIC discovered 1,915 records exposed in the ReimannCloud 04-07 Stealer log breach on 05-Apr-2023. The log landed in a public Telegram channel that day and bundles endpoints, emails, API hosts, and plaintext passwords lifted from infected machines.

Why This Stealer Log Is Dangerous

Stealer logs hand attackers plaintext passwords paired with the exact URL where each one works. That eliminates any need to crack hashes and lets criminals move straight to account takeover. Accompanying browser cookies can even bypass multi-factor prompts for days after the theft.

What Was Exposed in ReimannCloud 04-07

• 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

Each record maps a victim's identity to the banking, email, and retail services they used.

Why This Matters

Stealer logs from 2023 still fuel attacks today because victims often reuse passwords across many sites. Credential-stuffing bots cycle through old dumps in minutes, and mirror copies of this file continue to circulate on Telegram. Any infected device may also still contain the malware that produced the log.

How a Stealer log Like ReimannCloud 04-07 Works

Infostealer malware such as RedLine, Raccoon, or Lumma scrapes browser logins, cookies, and wallet files the first time a victim runs a cracked installer or malicious attachment. Operators bundle the results and post the archive to Telegram to attract buyers and mirrors. HEROIC ingests these channels so the exposures surface in our breach database.
