PegasusClaud Stealer Log: 8,669 Plaintext Passwords Exposed

Before PegasusClaud.20 ever existed, there was simply PegasusClaud, a stealer log dated November 27, 2023 that carried 8,669 records of stolen logins. The numbered sequels that came after it, like the .20 version, suggest this was less a single incident and more an ongoing malware operation releasing fresh batches over time.

Why This Is Dangerous

What separates a stealer log from most data breaches is where the information comes from. This wasn't pulled out of a company's server, it was scraped directly from victims' own devices, meaning the emails and plaintext passwords inside reflect exactly what those people were using at that moment. There's no delay and no guesswork for an attacker to deal with.

What Was Exposed

• Email addresses collected from browser sessions
• Passwords stored in plaintext with no protection layer
• URLs showing which services each set of credentials belongs to

Everything a criminal needs to log in somewhere is packaged together in one line per victim, which is what makes even a smaller file like this one worth taking seriously.

Why This Matters

A file under ten thousand records can feel minor next to leaks involving millions, but that thinking is exactly backwards. Smaller stealer logs frequently get less attention from researchers and less coverage overall, wich can mean the people in them stay exposed for longer before anyone flags the danger.

How This Malware Operation Appears to Work

The naming pattern between this file and its later version points to a single piece of malware, likely branded PegasusClaud by whoever built it, being deployed repeatedly against new victims over time. Each infection harvests saved credentials and autofill data, then reports back to the operator, who periodically packages and distributes a fresh log.

Check If You Are Affected

Rather than hoping your details weren't in this batch, check directly. HEROIC's free scanner compares your email against a database of over 400 billion leaked records pulled from breaches and stealer logs alike, giving you a clear result in moments. If you find a match, updating that password right away closes the door before it gets used.
