Inside the VENOMLOGSCLOUD Logs: How Malware Stole 7,175 Passwords

In May 2023, HEROIC analysts flagged a stealer log upload on a Telegram channel operating under the name VENOMLOGSCLOUD. The dump, labeled 361 LOGS, exposed 7,175 records belonging to real users whose devices had been silently compromised by infostealer malware. Each record contained an email address, a plaintext password, and the URL of the site where that password was used, giving attackers a ready-made set of working credentials that required no additional processing before use.

Why This Is Dangerous

Most data breaches involve hashed or encrypted passwords that require cracking before they can be used. This breach does not. The passwords in this dump are stored in plaintext, meaning they are immediatly usable with zero additional effort. An attacker who downloads this file can begin attempting logins on the same day it is posted.

The inclusion of specific URLs is what makes this data particularly valuable to criminals. Rather than guessing which services a victim uses, the attacker already knows the exact login page to target. This removes one of the few barriers that slow down credential-based attacks and makes VENOMLOGSCLOUD-style dumps far more dangerous than typical database leaks.

What Was Exposed

• Email addresses tied to real user accounts
• Plaintext passwords (no encryption, no hashing applied)
• URLs identifying the exact login pages each credential belongs to
• Endpoint metadata from 361 infected machines that contributed to the dump

Why This Matters

Credential stuffing is the most immediate threat. Attackers take the email and password pairs from logs like this one and run them against high-value platforms including banking portals, email providers, and e-commerce sites. Because password reuse is extremely common, a single stolen credential often opens multiple accounts simultaneously.

Once inside an email account, an attacker can trigger password resets across every linked service, leading to full account takeover. Financial fraud can follow within hours. In more targeted cases, the attacker may use the compromised email to launch phishing attacks against the victim's contacts. Identity theft is definitly a real risk when the exposed URLs reveal which sensitive services, such as healthcare or government portals, the victim was using.

How Stealer Logs Work

Infostealer malware is the engine behind every dump like this one. The infection typically arrives through phishing emails, cracked software downloads, or malicious browser extensions. Once installed, it quietly scans the device for saved browser passwords, active session cookies, and autofill credentials before packaging everything into a structured log file and transmitting it to the attacker's server.

VENOMLOGSCLOUD is a Telegram-based distribution channel for this type of output. Operators either run their own malware campaigns or purchase logs from other threat actors, then redistribute them to subscribers. The "361 LOGS" label describes 361 separate infected machines whose data was bundled into this single upload. Each machine can contribute credentials from dozens of different websites, which is how a relatively small infection footprint can produce thousands of exploitable records. Victims have no warning during the infection, and the first sign something is wrong is often an unauthorized login notification or unexpected account activity that occured hours or days after the data was already shared.

Check If You Are Affected

HEROIC maintains a breach database of over 400 billion compromised records, including stealer log archives like the VENOMLOGSCLOUD dump. You can search your email address for free to see if your credentials appeared in this breach or any other known exposure.
