A Single Login From UG-137.63.142.87 Quietly Surfaced Online
On 04-Aug-2026, HEROIC analysts logged a small stealer log file uploaded to Telegram and labeled UG - 137.63.142.87 - 20260804_120224. The file is tied to one infected device and contains a single record: an email address, a plaintext password, and the URL of the account it unlocks.
Why This Is Dangerous
A single record from a stealer log is still a fully working login. Because the password was captured directly from the infected device in plaintext and comes paired with the exact site URL, anyone with this file can log into that account right away.
What Was Exposed
- Email address
- Plaintext password
- URL of the affected login
Why This Matters
Stealer log files like this are frequently uploaded one infected device at a time, tagged with the device's IP address and a timestamp. If this credential belongs to you and matches a password you use elsewhere, an attacker could try that same login on your other accounts.
How Stealer Logs Work
This file was produced by information-stealing malware running on a device tied to the IP address 137.63.142.87. The malware copied saved login data from the browser and packaged it with the timestamp 20260804_120224 before it was uploaded to a Telegram channel where stealer logs like this are traded.
Check If You Are Affected
Even one exposed login is worth checking. HEROIC's free breach scanner checks your email against more than 400 billion exposed records, including this log, so you can confirm whether you were affected.
