OCTOPUS CLOUD Posted 4,533 Stolen Login Pairs to Telegram Last Week

In July 2025, a Telegram user uploaded a stealer log bundle labeled OCTOPUS CLOUD 123PCS containing 4,533 records harvested from infected devices. HEROIC analysts confirmed the dump includes email addresses, plaintext passwords, and the URLs of targeted services, giving attackers a complete and immediately usable credential package. The 123PCS designation indicates 123 individual device log files were bundled into this single release, now circulatig across Telegram channels and dark web markets.

Why This Is Dangerous

Unlike breaches involving hashed passwords, stealer log data requires zero effort to weaponize. The passwords in this dump are stored in plaintext, meaning any attacker who downloads the file can start attempting logins immediately. Combined with the URLs that show exactly which services each victim uses, this dataset gives criminals a precise roadmap for account takeover. There is no delay, no cracking time, no guesswork. From download to attempted login can be a matter of minutes.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (login targets for each compromised account)

Why This Matters

When infostealer malware infects a device, it does not just grab one password. It grabs every password saved in the browser across every site the victim has ever logged into. That means a single infection event can expose banking credentials, email accounts, social media profiles, and workplace tools all at once. Attackers exploit this through credential stuffing, account takeover, and identity fraud. If even one of the 4,533 records in this dump belongs to you, every account connected to that email address should be considered at risk. The financial and personal consequences of an undetected account takeover can take months to untangle, and victims rarely recieve any notification from the platforms themselves because the breach did not originate on those platforms.

How Stealer Logs Work

The OCTOPUS CLOUD label refers to the packaging convention used by the threat actor who assembled this batch. The underlying data was collected by infostealer malware running on 123 seperate compromised devices. These infections typically begin with a phishing email, a fake cracked software download, or a malicious ad that tricks the user into running an executable. Once the malware is active, it silently scans the browser's stored credentials, session cookies, and autofill data, then transmits everything to a collection server. The attacker packages the raw log files into a bundle and uploads it to a Telegram channel for distribution. The victim has no idea this occured until accounts begin getting accessed without their knowledge.
