The I – 242 PCS OCTOPUS Stealer Log Hit Telegram in 2023. The Data Is Still Active.

HEROIC analysts identified the I - 242 PCS - OCTOPUS stealer log during threat intelligence monitoring in August 2023. The file, posted to a Telegram channel by an anonymous actor, contained 6,635 records harvested from infected devices. Each record includes an email address, a plaintext password, and one or more URLs showing which websites and services the victim was accessing when the malware ran on their machine.

Why This Is Dangerous

This is not encrypted data. These passwords are written out in plain text, meaning anyone who downloads this file can read them directly. Combined with the email address and the list of services each victim was using, an attacker has everything needed to attempt immediate account takeovers with no additional tools or technicall knowledge required.

What Was Exposed in the I - 242 PCS OCTOPUS Log

• Email Addresses
• Plaintext Passwords
• URLs (sites and services the victim was accessing)

Why This Matters

The moment a stealer log goes live on Telegram, it is available to anyone in that channel. Attackers immediately begin credential stuffing, using automated tools to test each email and password pair across banking sites, email providers, and e-commerce platforms. A single working login leads to complete account takeover. From a compromised email account, attackers trigger password resets on connected services, enabling identity theft and financial fraud. With 6,635 records in this log, the potential for harm is significant and the window for action is narrow.

How Stealer Log Breaches Work

Stealer logs do not come from company databases. They come from individual devices. Infostealer malware infects a user's computer through a phishing email, a malicious software download, or a compromised website. Once on the device, it silently reads saved browser passwords, harvests active session cookies, and logs the URLs the user visits. It then bundles all of this into a structured log file and sends it to the attacker's server. The log is sorted by region or data type and then sold or shared in private Telegram groups and dark web forums. The entire proccess, from infection to data sale, can happen within a single day.
