How a Stealer Log Led to the Berserklogs October 600 Leak of 10,315

A stealer log titled "berserklogs - 600 LOGS OCTOBER" was uploaded to Telegram on October 15, 2022, and HEROIC analysts traced it back to infostealer malware running on individual victims' computers. The file contains 10,315 records combining email addresses, plaintext passwords, and the URLs those credentials were used on, the direct output of malware quietly siphoning saved logins off infected machines.

Why the Berserklogs October 600 Leak Is Dangerous

Plaintext passwords give attackers a head start most breaches don't: nothing to crack, nothing to decrypt. Add the matching URL for each account and this file becomes a step by step guide to logging into other people's accounts.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each login

Why This Matters

Data like this drives credential stuffing attacks, in which stolen logins are automatically tested against banking, email, and shopping accounts elsewhere. Anyone among the 10,315 people in this leak who reused their password is exposed to account takeover, fraud, or identity theft.

How a Stealer Log Like This One Is Built

It starts with a single infection: a cracked download, a malicious ad, or a booby-trapped attachment installs infostealer malware on a victim's computer. From there, the malware quietly copies saved browser passwords and sends them back to whoever is running it. That person compiles the stolen data into a log file, exactly like the 10,315 record file described here, and distributes it through Telegram channels and dark web forums.

Check If You Are Affected

If you were online around October 2022, take a moment to check whether your credentials appear in this leak. HEROIC's free breach scanner checks your email against more than 400 billion exposed records, including stealer logs like this one, so you can act fast and change any passwords that were compromised.
