How the 818 Hotmail Stealer Log Led to 818 Stolen Microsoft Logins on Telegram

HEROIC analysts identified a Hotmail-focused stealer log posted to a private Telegram channel in October 2025. The file, shared under the title 818 Hotmail, contained exactly 818 records pulled from infected devices. Each record consisted of a Hotmail or Outlook email address, a plaintext password, and a URL indicating the specific service where the credential was active. The file's precise focus on Microsoft email accounts makes it a compact but targeted package for anyone intending to access Microsoft services.

Why 818 Stolen Hotmail Logins Give Attackers Direct Access to the Microsoft Ecosystem

Every credential in this file connects to a Microsoft account, which means every record is a potential key to Outlook email, OneDrive storage, Microsoft 365 documents, Xbox gaming accounts, and any other service linked to that identity. Attackers do not need to work hard with files like this. The passwords are plaintext, the email addresses are confirmed Hotmail accounts, and the URLs indicate which services are associated. A criminal downloading this file can begin attempting logins within minutes using basic scripting tools. Accounts that have not been secured with multi-factor authentication are especially vulnerable.

What the 818 Hotmail Stealer Log Exposed

• Hotmail and Outlook email addresses
• Plaintext passwords with no encryption or hashing
• URLs associated with each stolen credential

Why Even a Small Hotmail Stealer Log Creates Serious Risk of Identity Theft and Financial Loss

Files with fewer than a thousand records are sometimes more dangerous than massive combolists because attackers can give individual attention to each account. Rather than bulk testing credentials and moving on, a criminal working through 818 records can manually explore each account, looking for bank connections, saved passwords, recovery emails, and sensitive documents. Comprimised Microsoft accounts are also frequently used to conduct phishing attacks against the victim's contacts, multiplying the damage beyond the original breach. Each person whose credentials appear in this file faces the risk of having their email accessed, their files read, and their identity used without their knowledge.

How Malware Led to 818 Hotmail Logins Being Stolen and Posted to Telegram

The chain that leads from a clean device to a credential appearing in a file like this one typically begins with a phishing email, a fake software installer, or a malicious browser extension. Once the malware is installed, it monitors the browser and operating system for saved credentials. When a user visits hotmail.com or outlook.com and logs in, the malware captures the email address, the password, and the URL in the moment of use, before any hashing can occur. That data is then sent to the attacker's server and eventually compiled into targeted files by email provider. The 818 Hotmail file was almost certainly extracted from a larger raw log and filtered automaticaly to include only Microsoft email accounts. It was then uploaded to Telegram where subscribers could download and use it freely.
