The E – 226 PCS OCTOPUS Stealer Log Means Someone Could Be Logging Into Your Accounts

HEROIC analysts discovered the E - 226 PCS - OCTOPUS stealer log while tracking threat actor activity on Telegram in August 2023. The file was uploaded by an anonymous user and contained 4,692 records pulled directly from infected endpoints. The data includes email addresses, plaintext passwords, and URLs showing exactly which websites and services the victims were logged into when their devices were compromised.

Why This Is Dangerous

With a plaintext password and an email address in hand, an attacker does not need to guess or crack anything. They simply try those exact credentials on banking sites, email providers, and shopping platforms. The URLs in this log make it even worse by showing which services each victim actually uses, turning a general data dump into a personalized attack guide for the criminal who holds it.

What Was Exposed in the E - 226 PCS OCTOPUS Log

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

Why This Matters

Stealer logs containning plaintext passwords are a direct path to credential stuffing attacks, where automated tools test the stolen login pairs across dozens of popular websites in seconds. A single match means full account takeover. Once an attacker controls an email account, they can reset passwords on every other service linked to it. This chain reaction leads directly to identity theft and financial fraud that can take months to untangle. The inclusion of URLs means attackers already know which services to target first.

How Stealer Log Breaches Work

A stealer log originates on the victim's own device, not on a company server. Infostealer malware is installed without the user knowing, usually through a phishing email, a fake app download, or a drive-by infection from a compromised website. Once running, the malware harvests saved browser passwords, active session cookies, and form autofill data. It bundles everything into a structured log and transmits it to the attacker's server. The logs are then organized by category and sold or traded in private Telegram channels and underground forums. Most victoms never know they were infected until they start seeing unauthorized logins.
