29,729 Plaintext Passwords From the hurricane_cloud Dump Just Surfaced on Telegram

In July 2025, a Telegram user uploaded a stealer log file labelled hurricane_cloud 690count that exposed 29,729 records of stolen credentials harvested from 690 infected devices. The dataset contains plaintext passwords, email addresses, and URLs captured directly from compromised endpoints across the United States. HEROIC analysts confirmed the breach and added it to the database on April 18, 2026. Because the file was distributed freely on a public Telegram channel, any threat actor who downloaded it has had months of unrestricted access to those credentials and can still use them today.

Why This Is Dangerous

The hurricane_cloud dataset is particularly dangrous because every credential in it is paired with the exact URL of the service it belongs to. Attackers do not need to guess which sites a victim uses. They already know. A banking password is listed next to the bank's URL. An email credential can be used to trigger password resets on every other account the victim owns. This combination of plaintext passwords and matched URLs creates a ready-made attack kit that can be deployed without any additional research or preparation. With nearly 30,000 records and months of circulation time, the potential for account takeover, identity theft, and financial fraud is immediate and real.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (browser-saved sites and active service endpoints)

Why This Matters

Credential stuffing attacks powered by plaintext password datasets are automated and fast. Attackers run tools that test thousands of login combinations per minute across banking sites, email providers, and e-commerce platforms simultaneously. For anyone who reused the same password across multiple accounts, a single compromised credential from this file can cascade into full account takeovers across banking, email, and social media in minutes. The hurricane_cloud data has been freely available since July 2025, and victims recieve no formal notification. Without actively checking, there is no way to know whether your credentials are already in the hands of someone who downloaded this file months ago.

How Stealer Logs Work

Infostealer malware runs invisibly in the background of an infected computer, scanning saved browser passwords, session cookies, autofill data, and browsing history. Within seconds of activation, it transmits everything to the attacker's server over an encrypted connection. The attacker bundles the harvested output from multiple devices into a single log file organized by device count, in this case 690count indicating 690 compromised machines, and distributes it through Telegram channels under handles like hurricane_cloud. The infection typically starts with a phishing email, a malicious software download, or a compromised browser extension. Victims almost never recieve any visible indication that their device was infected, and most discover the breach only after an account has allready been taken over.

Check If You Are Affected

HEROIC's free breach scanner searches across more than 400 billion exposed records, including the hurricane_cloud 690count stealer log, to tell you whether your email address or passwords appear in this breach or any other known dataset. Run your free HEROIC scan now, change any compromised passwords immediately, enable two-factor authentication on all accounts, and monitor for suspicious login activity. The sooner you check, the sooner you can close the door on attackers who already have your credentials.
