The POWERCLOUDMAIN SHTORM Breach Happened in March 2026. The Data Is Already Circulating.

HEROIC analysts tracked a stealer log batch posted to Telegram on March 24, 2026, released publicly under the label POWERCLOUDMAIN SHTORM FREE LOGS. The file contained 11,038 records harvested from infected devices, covering email addresses, plaintext passwords, and the specific URLs where those credentials were originally entered. The fact that this log was labeled as free and shared openly means it passed through many hands before being indexed in our breach database.

Why This Is Dangerous

When a stealer log is posted as a free download in a Telegram channel, the number of people who access it is impossible to count. Unlike data sold privately to a single buyer, a free public release means the credentials inside can be downloaded and misused by hundreds of different actors at once. Each one of those actors can immediately start testing those plaintext passwords against email providers, banks, and other online services without any special tools or skills.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (the exact login pages where credentials were captured)

Why This Matters

The March 2026 date means this data is very recent. Victims may still be using the same passwords today, which puts their accounts in immediate danger. Attackers prioritize fresh logs precisely because people have not yet had time to change their credentials. Account takeovers, unauthorized purchases, and identity theft can all begin within hours of a log like this going public. Anyone whose email appears in this dataset should treat every account tied to that address as compramised until proven otherwise.

How Stealer Logs Work

Infostealers are a category of malware that silently collect credentials from infected computers. They spread through phishing links, fake software cracks, and malicious browser extensions. Once active, the malware reads saved passwords from every browser on the device, logs what the user types, and grabs session cookies. Everything gets bundled into a neatly orginized log file that is uploaded automatically to the attacker's server. The POWERCLOUDMAIN SHTORM label indicates this log came from a recognized stealer operation that distributes logs through Telegram channels, often as promotional samples to attract paying customers.
