The SHTORM CLOUD Leak: 42,594 Passwords Exposed. Yours Might Be One.

HEROIC analysts identified a stealer log file uploaded to a public Telegram channel in January 2026, exposing 42,594 records from the POWERCLOUDMAIN - SHTORM CLOUD - FREE LOGS repository. The leak was verified on January 28, 2026 and contains email addresses, plaintext passwords, and API host URLs harvested from compromised endpoints. The combination of credential types exposed means attackers can recieve immediate, ready-to-use access to affected accounts without any additional cracking effort.

Why the SHTORM CLOUD Leak Is Dangerous

Stealer log leaks are among the most operationally dangerous breach types because the data requires zero processing before it can be weaponized. Unlike hashed password dumps, plaintext credentials can be used the moment they are downloaded. The public Telegram channel distribution means the data occured across criminal networks almost instantly, multiplying the number of threat actors who can act on it. API host URLs in the dataset lower barriers even further, giving attackers direct pathways into cloud infrastructure and integrated business applications.

What Was Exposed in the SHTORM CLOUD Leak

• Email Addresses
• Plaintext Passwords
• API Host URLs

Why This Matters Beyond the Numbers

With 42,594 records in circulation on a public Telegram channel, the blast radius of this leak extends well beyond direct victims. Organizations whose employees or customers appear in this dataset face risks of credential stuffing attacks, unauthorized cloud service access, and lateral movement through connected systems. The presence of API host URLs as a seperate data point means attackers are not limited to email account takeovers -- they can target backend infrastructure directly. Businesses relying on cloud services integrated with affected endpoints should treat this as an active threat.

How Stealer Log Breaches Work

Stealer logs are generated by infostealer malware installed on victim devices, typically through phishing emails, malicious downloads, or compromised software packages. Once active, the malware silently harvests saved browser credentials, session tokens, API keys, and other sensitive data from the infected endpoint. The collected data is packaged into log files and transmitted to attacker-controlled servers, then frequently sold or shared on dark web forums and platforms like Telegram. The SHTORM CLOUD leak follows this exact pattern: logs exfiltrated from compromised devices were bundled and uploaded to a free public Telegram channel for wide distribution.

Check If You Are Affected by the SHTORM CLOUD Leak

HEROIC's free breach scanner searches across more than 400 billion records -- including stealer logs like this one -- to tell you instantly whether your email address or credentials have been exposed. Because stealer log data is distributed in plaintext, a fast check is your first and most important line of defense.
