MARVEL_CLOUD Dump: 7,815 Stolen Login Credentials on Dark Web

HEROIC found the MARVEL_CLOUD stealer log on March 13, 2023, exposing 7,815 records with email addresses, plaintext passwords, and URLs from infected endpoints shared on Telegram.

Why the MARVEL_CLOUD Breach Is Dangerous

MARVEL_CLOUD is a recurring Telegram stealer log channel that operates across multiple daily releases. At 7,815 records, this dump provides attackers with a substantial credential set for immediate use in automated stuffing campaigns. The lack of date specificity in the filename suggests this may be an omnibus release combining captures from several collection sessions.

What Was Exposed in the MARVEL_CLOUD Leak

• Email addresses from 7,815 compromised browser sessions
• Plaintext passwords with no encryption or hashing applied
• Login URLs tying each credential to a specific service
• API host references from compromised endpoint environments

Why This MARVEL_CLOUD Data Puts You at Risk

Credential stuffing tools can test 7,815 plaintext pairs against banks, email providers, cloud storage platforms, and corporate portals simultaneously. Any service that accepts the same email-password combination becomes immediately vulnerable. From a successful email login, attackers trigger password resets for every linked account, opening the path to identity theft, wire fraud, and data exfiltration.

How a Stealer Log Works

Infostealer malware like RedLine or Raccoon infects a device through cracked software, phishing links, or malicious browser extensions. The malware reads saved browser passwords, autofill data, and session cookies, then sends the output to an operator. MARVEL_CLOUD operators bundle the results and release them to Telegram channels across multiple dated and undated drops.
