The lionking_cloud Log Contains Exactly 17,292 Credential Pairs

In July 2025, a Telegram user distributed a stealer log file containing exactly 17,292 records from the lionking_cloud 354count dataset. Each record represents a real device that was comprimised by info-stealer malware, with credentials harvested and packaged for distribution through underground channels. The file includes email addresses, plaintext passwords, and the specific URLs associated with each set of crendentials -- a precise and dangerous combination that requires no additional processing before being weaponized by attackers.

Why This Is Dangerous

The precision of stealer log data is what makes it uniquely dangerous. Unlike a breached database where millions of records may be outdated or incomplete, the lionking_cloud log contains 17,292 targeted credential sets that were active and in use at the time of infection. Attackers know exactly which website each password belongs to because the malware recorded the URL alongside the credential. This eliminates the guesswork that slows down traditional credential stuffing operations and allows for highly targeted account takeover attempts.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (associated login endpoints)

Why This Matters

Seventeen thousand credentials may seem modest compared to mega-breaches, but the quality of the data in stealer logs compensates for volume. Every one of the 17,292 records in the lionking_cloud dump is an actionable, plaintext credential pair tied to a specific service. Cybercriminals priortize stealer log data precisely because the conversion rate from stolen credential to successful login is far higher than with hashed database dumps. If your data is in this file, the risk is immediate and concrete.

How Stealer Log Breaches Work

Info-stealer malware is deployed through phishing campaigns, malicious browser extensions, pirated software, and drive-by downloads. Once executed on a victim's machine, it silently extracts saved browser passwords, session tokens, and autofill data. It records the URL each credential is associated with, making the harvested data immediately usable. The collected records are bundled into log files and sold or shared through Telegram channels and dark web markets. The lionking_cloud 354count file is one such bundle, representing 354 infected machines with an average of roughly 49 credentials per device.
