6,011 People’s Credentials Stolen in the berserklogs Stealer log

HEROIC analysts identified a stealer log file, labeled berserklogs - 345 LOGS MAY, uploaded to a Telegram channel by an anonymous user. The file is dated May 18, 2022, and contains 6,011 records tied primarily to accounts in the United States. Each record pairs an email address with a plaintext password and the URL of the site the login belonged to.

Why This Is Dangerous

Every password in this file was captured directly from an infected device, so it sits in plaintext with no encryption for an attacker to break. Because the matching login URL travels with each email and password, a criminal can go straight to the right page and try the credentials without any extra work.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

With 6,011 credential pairs in this file, attackers have a solid pool to hunt for reused passwords. Exposed email-and-password pairs like these routinely get loaded into automated credential stuffing tools and tested against banking sites, email providers, and social media platforms. Anyone whose password shows up here and used it elsewhere faces real risk of account takeover, identity theft, or financial fraud.

How a Stealer Log Like This Gets Made

Stealer logs come from infostealer malware, which infects a device through a phishing link or a bundled fake download and then quietly copies every password saved in the browser along with the web address each one is used on. Once collected, the results get packaged into a file like this one and shared on Telegram, where anyone can download and use it.
