The PegasusClaud Leak Could Unlock Your Bank, Email, and Social Media

In June 2024, HEROIC analysts identified a stealer log uploaded to Telegram by an anonymous user. The file, named PegasusClaud, contained 3,976 records including email addresses, plaintext passwords, and URLs harvested by infostealer malware from infected devices. The data was distributed in private Telegram channels where threat actors share and trade stolen credentials.

The PegasusClaud Leak Could Unlock Your Bank, Email, and Social Media

When a stealer log exposes your email and plaintext password, the first account to fall is rarely the last. Attackers who obtain a working credential do not stop at one service. They test it against your email provider, your bank, your cloud storage, your social media, and any other platform where you might have reused the same password. A single hit in the PegasusClaud dataset becomes the starting point for a chain of compromises.

The URLs included in this breach accelerate that process. They tell attackers exactly which services each victim was using, letting them skip the guesswork and go directly to the highest-value targets first. Email accounts are particularly valuable because they hold password reset links for everything else.

What Was Exposed in the PegasusClaud Stealer Log

• Email addresses
• Plaintext passwords (no cracking or decryption required)
• URLs (showing exactly which services victims were actively using)

Why the PegasusClaud Breach Creates Cascading Account Risk

The chain risk from a plaintext password breach like PegasusClaud works like this: an attacker gets your email and password, tries it on your email provider, gains access, uses that email inbox to reset passwords on your bank and other connected services, and works outward from there. Each successful account takeover enables the next one.

Even if you do not reuse passwords exactly, variations on the same base password, like adding a number or symbol to the end, are predictable. Credential stuffing tools include rules that test common variations automatically. A credential from the PegasusClaud file could be the first domino in a sequence that results in financiel fraud, identity theft, and months of account recovery work. The sooner you know your credentials were exposed, the sooner you can break the chain.

How the PegasusClaud Stealer Log Was Created and Distributed

Infostealer malware infects computers through phishing emails, fake software installers, and malicious browser extensions. Once active, the malware runs silently in the background, harvesting every password saved in the browser, every URL visited during an authenticated session, and any credentials entered manually into a login form. All of this data is bundled into a structured log and sent back to the attacker's infrastructure.

The PegasusClaud file was then uploaded to Telegram, where it became immediatley available to anyone in the relevant channels. The name suggests it may have been associated with a specific malware operator or reseller who used cloud-themed branding for their stolen log bundles. Regardless of origin, the data is real, the passwords are plaintext, and the risk to affected users is ongoing.
