Telegram alien ULP P803 Stealer Log Exposed 11.83M Logins

HEROIC logged 11,825,454 unique records from the Telegram alien ULP P803 by alien release on March 13, 2025. The log, labeled TXTLOG_ALIEN - 803, shipped through a Telegram distribution channel as a 57.7 million line URL:LOGIN:PASS package, weighted toward US-facing services.

Why This Stealer Log Is Dangerous

Telegram distribution speeds up exploitation. Channel members grab fresh logs the moment they drop, feeding credentials into stuffing bots and fraud pipelines before most victims know malware ever touched their device. The volume alone, nearly 12 million verified unique emails, guarantees that countless accounts match reused passwords elsewhere.

What Was Exposed in the Telegram alien ULP P803

• 11,825,454 unique email addresses
• Plaintext passwords pulled from browser stores
• Homepage URLs for each login pair
• Active credentials across banking, retail, and SaaS tools

Why This Matters

Because passwords appear in plaintext beside their target URL, attackers skip cracking entirely and move straight to account takeover. Victims may see unauthorized purchases, drained PayPal wallets, hijacked email, and fraudulent tax filings during US tax season, with infections often tracing back months to a single cracked software download.

How a Stealer Log Dump Works

Infostealers like RedLine, Vidar, Lumma, and StealC arrive via cracked software, malvertising, and phishing lures. Once executed they harvest browser-saved credentials, cookies, autofill data, and crypto wallets, then transmit the haul to a collector. The actor alien compiles these victim logs into numbered ULP parts and releases them through both BreachForums and Telegram for maximum reach.

Check If You Are Affected

Rotate browser-saved passwords, enable multi-factor authentication on banking, email, and workplace tools, and run a reputable antivirus scan to catch residual infostealer infections. Search the HEROIC scanner, backed by more than 400 billion breached records, to see if your email surfaces in the Telegram alien ULP P803.
