Our Analysts Found the HelloKittyCloud 130 Stealer Log Circulating on Telegram

HEROIC analysts monitoring Telegram channels for emerging credential leaks identified the HelloKittyCloud 130 file on October 17, 2023. Uploaded by an unidentified Telegram user, the log contained 2,422 records pulled from compromised endpoints. The data inside included email addresses, plaintext passwords, and URLs pointing to the services where those credentials were in use at the time of infection. The naming pattern, combining a recognisable phrase with a batch number, is consistent with how organised stealer log operators label successive releases, suggesting this was one of many drops from the same source.

Why the HelloKittyCloud 130 Plaintext Passwords Are an Immediate Threat

Plaintext passwords require no additional work before they can be used. Unlike hashed passwords, which need to be cracked before they become useful, the credentials in this file are ready to try against any login page the moment someone downloads it. The URLs in the log remove even the guesswork about where to try them. An attacker with access to this file has a direct, labelled set of credentials mapped to specific services and accounts. The only variable is how quickly they act before the affected users change their passwords.

What Was Exposed in the HelloKittyCloud 130 Dataset

• Email addresses
• Plaintext passwords
• URLs (services and login endpoints where credentials were actively in use)
• Endpoint and API host information

Why HelloKittyCloud 130 Matters for Account Security

A batch of 2,422 records may seem small compared to large database breaches, but size is not the relevant measure for stealer logs. What matters is quality, and stealer logs are high quality by design. Every credential in this file was actively in use on a real device at the time it was captured. These are not old, recycled passwords from years-old breaches. They are fresh credentials tied to real, current accounts. If any of those accounts use the same password elsewhere, attackers can chain the compromise across every platform where that password appears. Stealer log data does not degrade in value the way older database dumps do.

How Stealer Log Operations Like HelloKittyCloud Work

Stealer malware is typically distributed through cracked software, malicious ads, or phishing campaigns. Once a device is infected, the malware harvests every credential it can find: browser-saved passwords, session cookies, auto-fill data, and credentials entered into apps while the malware is active. It pairs each credential with the URL of the service it belongs to, then transmits the compiled log to an attacker-controlled server. These logs are then sorted and uploaded to Telegram, sometimes under branded names like HelloKittyCloud, which function as a kind of subscription service where subscribers recieve batches of fresh logs on a regular schedule. Victims typically have no way of knowing their credentials were captured until a breach scanner or an account takeover alert surfaces the evidence.

Check If You Were Caught in the HelloKittyCloud 130 Breach

HEROIC's free breach scanner searches more than 400 billion exposed records, including stealer logs, combolists, and database dumps sourced from dark web markets and private Telegram channels. If your email address or password appeared in the HelloKittyCloud 130 dataset or in any other known breach, the scanner will show you. The search takes seconds. If you find a match, change the exposed password on every account where you have used it, and enable two-factor authentication wherever possible. Do not wait for an account takeover to confirm what the data already shows. Check your exposeure now.
