317 Hotmail Passwords Were Just Dumped on a Telegram Channel

A stealer log collection simply labeled "Hotmail" appeared on a Telegram channel in June 2026, containing 317 compromised credential sets. Despite the modest record count, each entry delivers an email address, a plaintext password, and the specific URL where those credentials were saved. For the 317 individuals in this dump, the exposure is total — their login details are circulating in full view of anyone who downloads the file.

Why Plaintext Hotmail Passwords Are Immediately Exploitable

Every one of the 317 passwords in this collection is stored in plaintext — no hashing, no encryption, no barrier between the data and anyone who wants to use it. An attacker does not need specialized tools or computing power to exploit these credentials. They can copy a password directly from the file and log into the victim's account within seconds.

Hotmail and Outlook accounts are particularly valuable targets because they often serve as recovery email addresses for other services. If an attacker gains access to a victim's Hotmail account, they can trigger password resets on banking sites, social media platforms, and workplace tools — effectively cascading a single stolen credential into control over an entire digital identity.

What Was Exposed in the Hotmail Dump

• Email Addresses — 317 Hotmail and associated Microsoft email addresses, each serving as a login identifier across countless online services.
• Plaintext Passwords — Fully readable, unencrypted passwords harvested directly from browser credential stores on infected devices.
• URLs — The exact login pages where each credential pair was saved, providing attackers a precise map of which services each victim uses.

Why 317 Records Deliver Outsized Damage

A 317-record dump may appear negligible compared to million-record breaches, but smaller stealer log collections are often more dangerous in practice. Larger dumps attract security researcher attention and trigger rapid responses from platforms. A compact collection like this one flies under the radar, giving attackers more time to exploit credentials before victims learn they have been compromised.

Furthermore, every record in this dump represents a real, individual device infection. These are not recycled credentials from old breaches — they are freshly harvested logins captured from browsers in June 2026. The hit rate for successful account access is dramatically higher with fresh stealer logs than with aged credential databases, making each of these 317 records highly actionable for attackers.

How Stealer Logs Harvest Email Credentials

Infostealer malware infiltrates devices through phishing emails, malicious downloads, fake software updates, and compromised websites. Once installed, the malware silently extracts every saved credential from the victim's browsers — Chrome, Firefox, Edge, and others all store passwords in databases that infostealers know exactly how to read.

The harvested data is packaged by the malware operator and uploaded to distribution channels like Telegram, where it is sorted and labeled by email provider or region. A collection tagged "Hotmail" signals that the credentials target Microsoft email accounts specifically, making it easy for buyers to find exactly the type of access they are looking for. The entire pipeline from infection to exploitation can happen in days.

Check If Your Hotmail Credentials Were Exposed

If you use a Hotmail or Outlook email account, this leak is a direct signal to verify your exposure. The credentials in this dump were harvested recently, meaning they are almost certainly still active for victims who have not yet changed their passwords.

Use HEROIC's free breach scanner to check whether your email address or passwords appear in this Hotmail dump or across our database of 400B+ compromised records. If your credentials are found, change your Microsoft account password immediately, enable two-factor authentication, revoke any active sessions you do not recognize, and check for unauthorized forwarding rules that attackers commonly set up to maintain access even after a password change.
