July 13, 2026: 1,510 Hotmail Passwords Hit Telegram in Plaintext

On July 13, 2026, a stealer log file surfaced on Telegram containing 1,510 records tied to Hotmail accounts. HEROIC analysts confirmed the file includes email addresses, plaintext passwords, and URLs that track the browsing activity of each compromised user. The credentials became available to anyone monitoring these channels the moment the file was posted.

Why the Timing of This Hotmail Leak Matters

Every hour that passes after a stealer log goes public increases the danger to affected users. Once 1,510 plaintext password pairs are available on Telegram, they spread rapidly through criminal networks. Automated tools begin testing these credentials against popular services within minutes. By the time most victims learn their data is exposed, attackers may have already accessed their accounts, changed passwords, and locked out the rightful owners.

The browsing URLs in this log accelerate the attack timeline further. Instead of testing credentials blindly, attackers know exactly which services each victim uses and can prioritize high-value targets like banking portals, corporate email, and e-commerce accounts.

What Was Exposed in the Hotmail Credential Leak

• Email addresses from Hotmail user accounts
• Plaintext passwords with no encryption protecting them
• URLs revealing the specific websites and services each victim frequents

Why Hotmail Users Face Elevated Risk

Hotmail accounts are deeply integrated into the Microsoft ecosystem. A compromised Hotmail password can grant access to Outlook, OneDrive, Skype, and any third-party service where the user registered with their Hotmail address. Credential stuffing attacks exploit this by testing each stolen password across all of these platforms in rapid succession.

Account takeover through Hotmail credentials also opens the door to password reset attacks on other services. An attacker who controls your inbox can reset your passwords on banking, social media, and shopping sites by intercepting confirmation emails, effectively taking over your entire online presence.

How Stealer Logs Are Built and Distributed

Stealer logs begin with malware infection. Information-stealing trojans reach victims through phishing links, fake software updates, cracked applications, and malicious advertisements. Once the malware executes, it silently copies every password saved in the victim's browsers, captures session cookies that allow account access without passwords, and records the complete browsing history.

The stolen data is organized into structured log files, each containing all credentials from a single infected device. These files are then aggregated, sorted by email provider or target service, and distributed through Telegram channels and underground marketplaces. The 1,510 Hotmail records in this file likely represent a filtered subset of a larger collection sorted specifically for Microsoft email accounts.
