2026 Wako_Cloud_3 Breach: What 18,980 Users Need to Know

HEROIC researchers found 18,980 records on March 26, 2026 from Wako_Cloud_3, the third volume in the ongoing Wako_Cloud stealer-log series posted to Telegram.

Why This Stealer Log Is Dangerous

Wako_Cloud_3 follows two earlier installments, meaning its operators have a distribution pipeline and a receptive buyer base. The plaintext passwords inside are fresh, tied to active sessions, and ready for immediate credential stuffing against banking, email, and corporate login portals.

What Was Exposed in Wako_Cloud_3

• Email addresses
• Plaintext passwords
• Login URLs and API host endpoints
• Autofill values lifted from browsers
• Service mappings identifying which sites each credential unlocks

Why This Matters

18,980 credentials is enough raw material to breach thousands of reused accounts across banking, work SaaS, and cloud providers. As a serialized drop, Wako_Cloud_3 signals that more volumes are coming, so anyone exposed here is at elevated risk of follow-on attacks from the same threat cluster.

How a Stealer Log Like Wako_Cloud_3 Works

Infostealer malware lands on a device through cracked software, malicious installers, or phishing emails. It exfiltrates saved browser passwords, cookies, session tokens, and crypto wallet files. Operators then bundle the output into numbered releases like Wako_Cloud_1, _2, and _3 and post them to Telegram for resale or free distribution.
