1,082 Records Pulled From SunCloudNew Stealer Log Breach

HEROIC discovered 1,082 records exposed in the SunCloudNew 1143 - 5000 LogsFile.part3 Stealer log breach on March 18, 2026. The third installment in a segmented infostealer dump continues a serialized distribution pattern designed to maximize reach across multiple Telegram audiences.

Why This Stealer Log Is Dangerous

Even though 1,082 records seems small, each entry is a fully weaponized plaintext credential tied to an identified endpoint and API host. Multi-part releases like this one often total tens of thousands of records across the series, so victims face repeat exposure. The numbered filename also implies continued volumes are coming, pushing defenders into a reactive posture.

What Was Exposed in SunCloudNew

• Login credentials (usernames, passwords)
• Browser cookies and session tokens
• Autofill form data
• Crypto wallet data (where present)
• System fingerprints

The part 3 file contains endpoint-to-email-to-password mappings paired with API host URLs, a layout optimized for quick machine parsing by credential stuffing tools.

Why This Matters

Segmented drops like SunCloudNew's part 3 escape the attention given to mega-dumps yet still enable real account takeovers. Users whose records appear in this portion may reuse the same credentials on banking, email, or employer portals. Smaller dumps are also more likely to contain fresh, unburned credentials that evade existing stuffing blocklists.

How a Stealer Log Like SunCloudNew Works

Stealer malware lands on a victim PC through a trojanized crack, fake browser update, or malicious document. It sweeps every browser profile for saved logins, cookies, and autofill entries, then transmits the haul to a collection server. Operators split the combined logs into numbered parts such as 1143-5000 and post them serially on Telegram, keeping each file under platform size limits.
