Cloud User Credentials Exposed: The cvv190_cloud_2 Telegram Leak Hit 1,752 Accounts

HEROIC analysts discovered a stealer log file uploaded to Telegram in March 2026 under the filename "cvv190_cloud_2." The file contained 1,752 records collected from infected endpoints across the United States. Each record included an email address, a plaintext password, and the URL of the service that was accessed, giving anyone who found the file a direct map to compromised accounts.

Why This Is Dangerous

The name "cvv190_cloud_2" references CVV data and cloud infrastructure, suggesting this log was specifically targeting cloud-hosted services and possibly financial platforms. Plaintext passwords require zero effort to use. Combined with the URLs indicating exactly which services were breached, this is a high-efficiency credential package that bad actors can act on immediately after downloading.

What Was Exposed

The following data types were confirmed in this stealer log:

• Email addresses
• Plaintext passwords
• URLs (showing which cloud and online services were accessed on compromised devices)

Why This Matters

Cloud service credentials are particularly valuable to attackers because they often unlock access to business tools, file storage, email, and payment platforms all at once. When email and password pairs from a cloud-focused stealer log are used in credential stuffing campaigns, the potential for account takeover extends far beyond a single service. From there, attackers can pivot into identity theft, financial fraud, and even corporate network access if the affected account belongs to a business user. The 1,752 people in this log may have had multiple accounts compromised without ever knowing their device was infected.

How Stealer Log Breaches Work

Stealer logs are created by infostealer malware that runs silently on a victim's computer after being installed through a phishing link, malicious attachment, or trojanized software download. Once active, the malware records keystrokes, captures saved browser credentials, and logs every URL the user visits. All of this data is bundled into a log file and sent to the attacker. The attacker then distributes the log through private Telegram channels or dark web markets. The cvv190_cloud_2 file is part of this well-established criminal distribution chain, uploaded by an anonymous Telegram user and made available to anyone with access to the channel.
