A Telegram Upload Exposed 53 Synology Device Logins Overnight

Picture a small business owner logging into their Synology network storage device on a quiet Friday, unaware that somewhere on Telegram, their credentials just became one of 53 records inside a freshly uploaded stealer log called Good_Synology. The upload occured on October 31, 2025, and it targets exactly the kind of device many small offices trust to hold their backups.

Why This Is Dangerous

Synology devices often store backups, photos, and sensitive business files, all sitting behind a login that many people never bother to change. A stolen credential here is not just an email account, it can be a direct door into a device full of personal or company data kept in one seperate, easy-to-reach place.

What Was Exposed

• Email addresses
• Plaintext passwords
• Device and login URLs
• 53 total records exposed

Why This Matters

A small leak does not mean small consequences. If your Synology login is among these 53, an attacker could access years of stored files, backups, or personal media without you knowing until something goes wrong.

How Stealer Malware Grabs Logins Like These

Info-stealing malware installs itself quietly, often disguised as legitimate software, then scans the infected machine for saved passwords in browsers and apps, including device management tools like Synology's. Everything it finds gets bundled and uploaded, in this case to a Telegram channel, for other criminals to browse through.

Check If You Are Affected

Even with just 53 records, it is worth checking your own email against this leak. HEROIC's free scanner searches more than 400 billion breached records in seconds, giving you a clear answer instead of a guess.
