15,381 Passwords From the SunCloudNew 1726 Stealer Log Just Surfaced on Telegram

HEROIC analysts found 15,381 records exposed in the SunCloudNew 1726 - 550 LogsFile stealer log, uploaded to Telegram by an anonymous user on May 5, 2026. The leaked data includes email addresses, plaintext passwords, and URLs from compromised endpoints and API hosts.

Why SunCloudNew 1726 - 550 LogsFile Data Is Dangerous

Stealer log files targeting cloud infrastructure carry outsized risk. The combination of email credentials, plaintext passwords, and API endpoint URLs in a single file gives attackers everything they need to breach cloud accounts and connected services. Because this data is recent and unencrypted, it can be deployed in attacks immediately after the file is obtained.

What Was Exposed in the SunCloudNew Breach

• Email addresses
• Plaintext passwords
• URLs (endpoint and API host addresses)

Why the SunCloudNew Leak Matters

Cloud platform credential leaks have a compounding effect. Once attackers access one cloud account, they can often pivot to connected services, storage buckets, and internal tools. Credential stuffing using these email and password pairs puts every service where a victim reused their password at risk. Account takeover at scale follows, and in the worst cases, the stolen data enables full identity theft as attackers accumulate enough personal information from multiple accounts to impersonate victims.

How Stealer Logs Work

Stealer malware is delivered through deceptive means: fake software updates, cracked applications, or phishing links. Once running on a device, it quietly extracts saved credentials from browsers, password managers, and session cookies. The harvested data is compiled into log files, often containing hundreds of records per device, and sent back to the attacker automatically. The 550 log files referenced in this dataset represent 550 separate infected machines, each contributing records to the final dump that was then shared on Telegram.
