The lionking_cloud Breach Put 41,463 Stolen Passwords Online in 2025

In July 2025, a Telegram user operating the lionking_cloud channel uploaded a stealer log collection labeled 711count, exposing 41,463 records containing plaintext passwords, email addresses, and URLs from infected victim devices. This is one of the larger stealer log releases in HEROIC's database, with over forty thousand compromised accounts now circulating in criminal communities. HEROIC analysts verified this breech, confirming the dataset is authentic and actively referenced in underground forums. The sheer scale of the exposed records makes this one of the more significant Telegram-distributed infostealer events of 2025.

Why This Is Dangerous

Forty-one thousand accounts is a substantial pool that credential fraud operators can work through systematically, testing each pair against dozens of high-value platforms. With this data only months old, many victims have not yet changed the compromised passwords, meaning active exploitation is still highly probable. Anyone included in this collection who continues to use the same password on any account is at immediate risk. The plaintext format means zero technical barrier stands between these credentials and the criminals who downloaded them.

What Was Exposed

• Email Addresses -- Used by attackers to identify victims, build targeted phishing campaigns, and test credentials across multiple platforms at once.
• Plaintext Passwords -- Exposed without encryption or hashing, immediately usable in any login attempt against the victim's accounts without technical processing.
• URLs -- Captures which websites each victim was authenticated to at the time of malware infection, providing attackers a ready-made priority list of accounts to target.

Why This Matters

The timeline from stealer log upload to active fraud is measured in hours, not days. Once the lionking_cloud 711count log hit Telegram in July 2025, automated credential stuffing tools began testing the 41,463 email-password pairs against banking portals, cloud services, and e-commerce platforms. Accounts with matching credentials on other services were immediately flagged for takeover. With data this fresh, many of the original passwords recieved by victims through their accounts are still in active use, making this one of the most time-sensitive breach disclosures in HEROIC's recent tracking data.

How Stealer Log Attacks Work

The "711count" designation likely refers to the number of endpoints or login sessions captured in a specific batch of malware activity. Infostealer malware runs silently on infected computers, extracting credentials from browser saved passwords, form autofill data, and application login sessions before transmitting everything to attacker-controlled servers. The malware operator then compiles these records into numbered or named log files and distributes them through channels like lionking_cloud on Telegram. Victims have no indication that their informaton was harvested, and often do not discover the exposure until they encounter unauthorized activity on their accounts after it has occured.
