The CLOUDHEAVENLOGS Dump Put 10,063 Multi-Country Credentials on Telegram

HEROIC analysts confirmed a stealer log collection published to Telegram in May 2023, distributed under the label CLOUDHEAVENLOGS. The dataset contained 10,063 records pulled from compromised devices across multiple countries, with the "R COUNTRY" designation indicating a multi-region targeting scope. The exposed data included email addresses, plaintext passwords, and URLs, providing attackers with immediate, ready-to-use credentials for a range of online accounts.

Why Multi-Region Stealer Logs Carry Elevated Risk

When a stealer log targets endpoints across different countries, the credential pool becomes especially valuable on dark web marketplaces. Attackers can sort the data by region, language, or domain type to focus on high-value targets. Plaintext passwords require no additional cracking, meaning every record in this dump is actionable the moment someone downloads the file.

The URL component of this breach is what seperate it from a basic credential dump. Rather than just knowing an email and password, attackers can see exactly which services each victim was logged into, allowing for precision targeting of banking, corporate, and personal accounts.

What Was Exposed in the CLOUDHEAVENLOGS Dump

• Email addresses (login identifiers across virtually all online services)
• Plaintext passwords (immediately usable, no decryption needed)
• URLs (a map of the specific sites each victim was authenticated to)
• Endpoint data (device and API host information from infected machines)

Why This Matters: From Stolen Log to Compromised Account

Stealer log data is one of the primary fuels for credential stuffing operations. Automated bots cycle through thousands of username and password combinations per minute, testing them against popular platforms. If you use the same password on multiple sites, one compromised account can become many.

Beyond credential stuffing, the URL data in this dump enables account takeover with near-surgical precision. Financial fraud, identity theft, and unauthorized access to corporate systems are all real downstream consequences. Victims rarely recieve a warning, because there is no central breach notification for stealer log publications on Telegram.

How CloudHeaven-Style Stealer Log Operations Work

CLOUDHEAVENLOGS is a distribution label used by threat actors who bundle and sell or freely publish stealer log files, typically sourced from infostealer malware campaigns. Infostealers like RedLine, Vidar, and Raccoon are deployed through phishing campaigns, malicious ads, and trojanized software packages. Once installed, they harvest saved credentials from browsers, email clients, and applications, then upload the results to an attacker-controlled server.

The "428PCS" designation in this breach's filename indicates it was one package of 428 individual log files, each representing a seperate compromised device. The bundling and redistribution of these packages on Telegram channels allows the data to spread far beyond the original attacker, reaching hundreds of downstream threat actors who use it for fraud and account takeover campaigns.

What makes these operations particulary damaging is the speed of the pipeline. A device can be infected, the credentials harvested, and the log published within hours. Victims often don't realise their data is circulating until accounts start showing suspicious activity.

Check If Your Accounts Were Caught in This Breach

HEROIC's breach scanner indexes over 400 billion records from breaches, stealer logs, and dark web sources, including dumps like CLOUDHEAVENLOGS. If your email address or any of your passwords appeared in this dataset, a free scan at heroic.com will flag it. Checking your exposure takes less than a minute and could prevent account takeovers before they happen.
