How the InfernoLogsCloud Stealer Operation Leaked 732 Login Credentials

HEROIC analysts discovered the InfernoLogsCloud URL LOG PASS FREE202 stealer log, uploaded to Telegram on October 25, 2025, by an anonymous threat actor operating under the InfernoLogsCloud brand. The dataset contains 732 records exposing email addresses, plaintext passwords, and the URLs where credentials were originally captured. The FREE202 designation in the filename suggests this was distributed as a free sample to attract buyers to a larger paid dataset.

Why the InfernoLogsCloud Distribution Model Is Especially Dangerous

Threat actors who brand their stealer logs, like InfernoLogsCloud, operate as organized criminal businesses. They distribute free samples to prove data quality, then sell larger batches to paying customers. This means the 732 records in this file are likely a small fraction of a much larger dataset already in the hands of multiple buyers. The cloud-themed branding also suggests this log may have been filtered to prioritize cloud service and SaaS credentials, which carry higher value for attackers targeting business accounts.

Data Exposed in the InfernoLogsCloud FREE202 Stealer Log

• Email Addresses
• Plaintext Passwords
• URLs (specific services and login pages where credentials were captured)

How Attackers Monetize InfernoLogsCloud Data

• Credential stuffing: Each email and password pair is tested across banking, cloud, and SaaS platforms in automated attack sequences
• Account takeover: Cloud and SaaS credentials are especially valuable for corporate account compromise and lateral movement
• Identity theft: Email account access obtained from this log enables full password-reset chains across all linked services
• Financial fraud: Cloud billing accounts and corporate payment methods stored in compromissed accounts are high-value targets

How the InfernoLogsCloud Stealer Operation Worked

InfernoLogsCloud is a branded Telegram channel that distributes stealer log data under a recognizable name to build credibility in cybercriminal markets. The underlying data is harvested by infostealer malware, commonly RedLine, Vidar, or Lumma Stealer, which infects victim devices through phishing, malicious ads, or compromised software installers. Once running on a device, the malware silently extracts saved browser credentials, cookies, and autofill data before uploading everything to the operator's collection infrastructure. The operator then packages selected records, brands them under InfernoLogsCloud, and distributes free samples to demonstrate the dataset's value. This businesslike approach means the data circulates widely and quickly across multipple Telegram channels and dark web forums after initial release.
