Brazil-Based Users Targeted in the 52 Record 270736_BR Stealer Log Leak

HEROIC analysts confirmed the 270736_BR_177.221.132.154_07-06-23 stealer log appeared on Telegram in June 2023, exposing 52 records harvested from machines tied to a Brazil-based IP address. Each record includes an email address, a plaintext password, and URLs of sites the victim was actively using. The log is part of a larger June 2023 campaign that targeted users across multiple countries and distributed stolen credentials through Telegram channels.

Why the 270736_BR Stealer Log Is Dangerous

Each of the 52 records pairs a working email address with a plaintext password. There is no cracking or decoding needed. Attackers can use these credentials immediately to attempt logins on email providers, banking apps, social media, and e-commerce sites. The URLs in the log reveal which services each victim was using, helping attackers pick the most valuable accounts to target first.

What Was Exposed in the 270736_BR Stealer Log

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

People whose credentials appear in a stealer log face immediate risk of account takeover. Once an attacker has your email login, they can reset passwords across every service linked to that address. Banking, investment accounts, work email, and personal data can all be accessed within minutes of a successful takeover. Victims often do not find out until fraudulent charges appear or they are locked out of their own accounts.

How Stealer Logs Like the 270736_BR File Work

Stealer logs are produced by malware that infects individual computers. The malware extracts saved passwords from browsers, records the URLs the user visits, and bundles everything into a structured file. That file is then transmitted to the attacker and distributed through underground Telegram channels. The 270736_BR designation indicates the log was collected from a machine using a Brazilian IP address, making it part of a geographically targeted campaign that spread across multiple countries in the same upload wave.
