Dark Web Intel: The 166PCSOTTOHELP Stealer Log Exposed 1,725 Logins

HEROIC analysts identified a stealer log file uploaded to a Telegram channel on October 29, 2025, labeled "28-10-2025-166PCSOTTOHELP." The file contained 1,725 records pulled from an infected device, pairing email addresses with plaintext passwords and the API host URLs those credentials unlock. Though smaller in scale than many stealer logs, it carries the same direct risk to the people whose data it contains.

Why This Is Dangerous

Because the passwords in this log are stored in plaintext, an attacker does not need to crack or guess anything. They can pull an email and password pair directly from the file, open the matching URL, and log in immediately as the account owner. The inclusion of API host URLs also raises the risk of unauthorized access to programmatic systems, not just standard login pages.

What Was Exposed in the 166PCSOTTOHELP Stealer Log

• Email addresses
• Plaintext passwords
• API host URLs

Why This Matters

Even a small stealer log like this one feeds credential stuffing attacks, where attackers automatically test stolen email and password pairs against banking sites, email providers, and social media platforms. Anyone among the 1,725 people in this log who reused a password on another account faces a real risk of account takeover, identity theft, and financial fraud.

How the 166PCSOTTOHELP Stealer Log Was Created

A stealer log is produced by infostealer malware that infects a device, usually through a fake download, cracked software, or a phishing link. Once running, the malware quietly copies saved browser passwords and autofill data, bundling everything into a single file. That file then circulates on platforms like Telegram, exactly where this log surfaced, letting anyone who obtains it use the credentials directly without ever needing to breach the services named inside.
