Dark Web Intel: 2,369 Credentials From the DuckCloud 300 Dump

HEROIC analysts tracked a stealer log dump known as DuckCloud 300, uploaded to a Telegram channel and dated back to August 2023. The file contains 2,369 records pulled from infected devices, including email addresses, plaintext passwords, and the login URLs tied to each set of credentials.

Why the DuckCloud 300 Dump Is Dangerous

This isn't a database that was hacked and later cracked. It's a raw capture from malware sitting on a victim's computer, which means the 2,369 passwords inside are stored in plaintext exactly as they were typed. Each one is already paired with the website it unlocks, so an attacker can move straight from opening the file to logging into someone's account with no extra work.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Because the credentials are ready to use, this data is a direct path to account takeover for anyone who reused one of these passwords elsewhere. Attackers run credential stuffing scripts that test the same email and password pair against banking sites, email providers, and social media platforms, looking for a match. Once they get in, identity theft and financial fraud usually follow.

How Dark Web Stealer Dumps Like This Circulate

Infostealer malware infects a device, often through a pirated program or a malicious attachment, then quietly copies saved browser passwords, autofill entries, and active login sessions before sending them back to whoever controls the malware. The resulting file gets packaged and posted to Telegram channels and dark web forums like the one where DuckCloud 300 appeared, where it can be shared, traded, or sold to other criminals for further use.

Check If You Are Affected

You don't need to track down every dump that surfaces on Telegram to know if you're at risk. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs like DuckCloud 300, so you can see exposure and reset any affected passwords right away.
