12,778+ Accounts at Risk: SunCloudNew 1653 Stealer Log Breach Explained

HEROIC discovered 12,778 records exposed in the SunCloudNew 1653 stealer log breach on March 22, 2026. A Telegram user uploaded the 650-logs file containing email addresses, plaintext passwords, and service URLs captured from infected devices.

Why This Stealer Log Is Dangerous

The SunCloudNew 1653 drop packs more than 12,000 usable logins into a single archive, each one paired with a direct URL pointing to the exact service at risk. Because passwords are stored in plaintext, attackers skip the usual cracking phase and move straight to account takeover. Telegram distribution makes this archive trivially easy for any opportunist to grab.

What Was Exposed in SunCloudNew 1653

• Email addresses from 12,778 compromised endpoints
• Plaintext passwords lined up with target URLs
• Login URLs revealing exposed services
• Browser autofill and session artifacts
• Device fingerprints from infected machines

The structured format lets attackers load the data into credential stuffing tools with minimal preparation.

Why This Matters

Over 12,000 credentials is enough volume to trigger meaningful hits against banking, gaming, cloud, and enterprise logins. Because the source date is recent, the data is unlikely to be rotated or expired, raising the odds of successful compromise. Organizations whose staff or customers appear in the log should expect follow-on phishing, SIM swap, and ATO attempts.

How a Stealer Log Like SunCloudNew 1653 Works

Infostealer malware lands on endpoints through trojanized installers, fake software cracks, or phishing. It then harvests saved browser credentials, cookies, and token files. Operators organize the stolen data into batches, tag them with identifiers like SunCloudNew 1653, and push them to Telegram channels for resale or free distribution.
