1,435 Plaintext Passwords Were Just Dumped on Telegram

HEROIC's DarkHive intelligence platform detected a stealer log dump titled Hotmail Ubisoft Inboxed Hits 2, containing 1,435 compromised records. Posted to a Telegram channel in November 2024, this dataset includes Hotmail email credentials linked to Ubisoft services, all harvested from devices infected with infostealer malware.

The Danger of Passwords Stored in the Clear

None of the passwords in this breach are encrypted, hashed, or otherwise protected. They sit in the file as plain, readable text. This means anyone who downloads this stealer log — whether a sophisticated cybercriminal or an opportunistic script kiddie — can immediately use these credentials to attempt logins. There is zero barrier between exposure and exploitation.

What Was Exposed

• Email Addresses — Hotmail accounts associated with Ubisoft logins
• Plaintext Passwords — Completely unprotected, usable as-is
• URLs — Targeted service endpoints where the credentials were entered

Credential Stuffing: Why Reused Passwords Multiply the Damage

Attackers do not stop at one service. They feed stolen email-password combinations into automated tools that try those same credentials against hundreds of websites simultaneously. If you used the same password for your Ubisoft account and your bank, email, or work login, a single entry in this stealer log could give an attacker access to all of them. This technique, known as credential stuffing, is one of the most common and effective forms of cyberattack today.

How Stealer Logs Are Created

Stealer logs originate from infostealer malware infections. Programs like Vidar, RedLine, and Aurora are distributed through phishing campaigns, trojanized software, and malvertising. Once installed on a victim's device, the malware silently extracts stored passwords from browsers, grabs session cookies, and captures autofill data. The harvested credentials are compiled into structured log files and sold in bulk on dark web marketplaces or distributed freely on Telegram.
