How CLOUDHEAVENLOGS 895PCS Malware Led to 10,468 Stolen Logins

In May 2023, a Telegram operator uploaded a stealer log file tracked as CLOUDHEAVENLOGS 895PCS, exposing 10,468 records siphoned from infected endpoint devices by infostealer malware. The collection includes plaintext passwords, email adresses, and targeted service URLs across a wide range of online platforms. The data has been independently verified and continues to circulate in underground channels where threat actors buy and trade archived credential dumps. Understanding how this breach happened is the first step to knowing wheather your accounts are still at risk today.

Why This Is Dangerous

Stealer log collections are among the most operationally dangerous breach types because the credentials they contain are harvested live from victim machines rather than extracted from a static database. By the time a log surfaces on Telegram, the affected accounts are still likely active and vulnerable. With plaintext credentials and URL maps in hand, attackers can launch credential stuffing attacks, sell individual account access on underground forums, abuse saved session tokens to bypass password checks entirely, and leverage API keys for unauthorized backend access.

What Was Exposed

• Email Addresses -- 10,468 account identifiers across multiple service categories
• Plaintext Passwords -- credentials captured in unencrypted form, ready for immediate reuse by attackers
• URLs -- login pages, API endpoints, and backend service addresses targeted by the malware on each device

Why This Matters

With 10,468 plaintext credentials in circulation, this dataset creates meaningful risk across multiple industry sectors. Online services, cloud platforms, and enterprise SaaS tools are all common targets in stealer log campaigns. Credential stuffing bots test each email and password pair against banking portals, streaming services, and retail accounts around the clock. Once inside, attackers change passwords and recovery addresses to lock out the legitimate owner, drain stored payment methods, and harvest personal data to commit identity theft on other platforms.

How Stealer Log Malware Works

The CLOUDHEAVENLOGS 895PCS breach began on individual Windows machines infected by infostealer malware. These programs are delivered through phishing emails, trojanized software installers, and malicious browser extensions. Once installed, the malware silently harvests saved browser passwords from Chrome, Edge, Firefox, and Brave; active session cookies that allow login without a password; email and FTP client credentials; autofill data including payment card details; and API keys from developer environments. All harvested data is bundled into a compressed log archive and transmited to the attacker's server, then distributed through Telegram channels like CLOUDHEAVENLOGS in batches of hundreds of records at a time.

Check If You Are Affected

HEROIC has indexed over 400 billion compromised records including stealer logs like CLOUDHEAVENLOGS 895PCS and thousands of other Telegram-sourced datasets. Even if the malware infected your machine in 2023, your credentials may still be active and exploitable today.
