ReimannCloud 11-13 Traced to Public Telegram: 2,494 Victims

HEROIC discovered 2,494 records exposed in the ReimannCloud 11-13 stealer log breach on April 5, 2023. The archive was traced to a public Telegram channel, where a user published endpoint data, email accounts, API hosts, and plaintext passwords collected from infostealer victims.

Why This Stealer Log Is Dangerous

Public Telegram channels give anyone with a free account immediate access to credential dumps. No dark-web skill or bitcoin wallet is required, which dramatically lowers the barrier to credential stuffing, SaaS intrusion, and crypto theft.

What Was Exposed in ReimannCloud 11-13

• 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

HEROIC confirmed 2,494 records tied to the 11-13 drop on Telegram.

Why This Matters

When a source is a public channel, the same file circulates across hundreds of mirror bots and resale forums within hours. Victims rarely learn of the exposure until fraudulent transactions or password resets begin. Verifying exposure early shrinks that window.

How a Stealer Log Like ReimannCloud 11-13 Works

Infostealer malware lands on a victim's machine via phishing, malvertising, or trojanized installers. It scrapes credentials, cookies, and wallets, packages them into a dated log, and the operator pushes the archive into a Telegram channel for free distribution or paid resale.
