Dark Web Intel: 5,152 Credentials From the PegsusCloud Stealer Log

HEROIC analysts identified a stealer log named PegsusCloud uploaded to Telegram in June 2024. The file contains 5,152 records pulled from devices infected with information-stealing malware, including email addresses, plaintext passwords, and the URLs of the sites those credentials unlock. Unlike a single-company data breach, a stealer log is a snapshot of everything saved in an infected browser at the moment the malware ran.

Why the PegsusCloud Stealer Log Is Dangerous

Stealer logs hand attackers working logins, already matched to the exact site they belong to. There's no guessing or cracking involved. Whoever holds the PegsusCloud file can open each URL, drop in the paired email and password, and be logged into a real account in seconds, whether that's email, banking, shopping, or a work login saved in someone's browser.

Because the malware captured whatever was stored on the infected device at that moment, the 5,152 records in this log are current, working credentials rather than old, already-changed passwords.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the accounts and login pages tied to each credential

Why This Matters

Every credential in the PegsusCloud log is a potential account takeover waiting to happen. Because stealer malware grabs everything saved in a browser at once, one infected device can hand attackers access to email, banking, social media, and shopping accounts in a single sweep. That makes stealer logs especially valuable for credential stuffing, financial fraud, and identity theft, since the attacker already knows exactly which site each password unlocks.

How Stealer Logs Work

Information-stealing malware, often called a "stealer," infects a device through a malicious download, cracked software, or a phishing link. Once running, it quietly scrapes passwords and autofill data saved in the browser, along with cookies and the web addresses tied to each login, then sends everything back to the attacker as a single file, or "log." The PegsusCloud log, with 5,152 records, is one infected device's worth of that harvested data, packaged up and sold or shared on Telegram like the countless other stealer logs traded daily on the dark web.

Check If You Are Affected

If you think a device of yours may have been compromised, or you simply want to check whether your email shows up in a log like PegsusCloud, HEROIC's free breach scanner searches a database of more than 400 billion leaked records in seconds. If you find a match, change that password right away, update it anywhere else you reused it, and run a malware scan on the device in question.
