1,555 Passwords Exposed in ReimannCloud 07-03 Stealer Log

HEROIC discovered 1,555 records exposed in the ReimannCloud 07-03 Stealer log breach on 05-Apr-2023. The file was posted into a public Telegram channel and packages endpoints, emails, API hosts, and plaintext passwords harvested from infected machines.

Why This Stealer Log Is Dangerous

Stealer logs deliver plaintext passwords straight from victim browsers, so attackers skip any cracking step. Matching URLs reveal exactly which banking, email, or workplace sites to target next. Session cookies in the same archive can also bypass multi-factor prompts until the victim explicitly revokes them.

What Was Exposed in ReimannCloud 07-03

• 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 pairs a victim's identity with the specific services they logged into.

Why This Matters

Even a 1,555-record log can trigger a wave of account takeovers because victims typically reuse the same password across many sites. Criminals feed the file into credential-stuffing tools and sell refined access to targeted services. Exposure lingers because mirror channels keep redistributing the dump long after takedown attempts.

How a Stealer log Like ReimannCloud 07-03 Works

Infostealer malware such as RedLine, Raccoon, or Lumma quietly exfiltrates browser data when victims open cracked software or malicious attachments. The operator aggregates logs and posts them to Telegram channels to advertise fresh data. HEROIC ingests those channels so exposed records land in our breach database within hours.
