Zimbra WRTCloud Stealer Log Leaks 11 Accounts’ Emails and Passwords

HEROIC analysts identified a stealer log file uploaded to a Telegram channel on 13 February 2026, tied to a system labeled "zimbra_wrtcloud." The file contains 11 records pulled directly from an infected device, including email addresses, plaintext passwords, and the URLs of the accounts they unlock. While the record count is small, every entry includes a working password captured in cleartext, which makes this a high-confidence, ready-to-use dataset for anyone who gets their hands on it.

Why This Is Dangerous

Unlike a database dump scraped from an old breach, a stealer log comes straight from a victim's own browser or credential manager at the moment it was infected. That means the passwords in this file were valid and in active use when they were stolen. Paired with the exact URL each password belongs to, an attacker does not need to guess which login a credential opens. They can go straight to the account, log in, and take over.

What Was Exposed

• Email addresses tied to each compromised account
• Plaintext passwords, stored and leaked with no encryption
• URLs identifying the exact site or service each login unlocks

Why This Matters

Even a handful of exposed logins can cause real damage. If any of these 11 people reused a password across other sites, which most people do, attackers can run that same email and password pair against banking portals, email providers, and social media through automated credential stuffing tools. From there it is a short path to account takeover, financial fraud, or full identity theft. Small numbers do not mean small risk when the passwords are real and unencrypted.

How Stealer Log Uploads Like This Happen

A stealer log is generated by malware, often called an infostealer, that quietly infects a victim's computer, usually through a fake download, cracked software, or a malicious email attachment. Once running, the malware scans the browser's saved logins, autofill data, and session cookies, then packages everything into a text file and sends it back to whoever controls the malware. Criminals collect thousands of these logs and dump batches of them, like this one, into Telegram channels where other threat actors buy, trade, or use them directly.

Check If You Are Affected

If you have ever reused a password across accounts, this kind of exposure is exactly what puts you at risk, even when the leak itself looks small. HEROIC's free breach scanner checks your email against a database of more than 400 billion exposed records, including stealer logs like this one, so you can find out in seconds whether your credentials are already circulating on the dark web.
