Researchers Found 69,516 Stolen Credentials in the NewWlfrCloud Telegram Dump

In August 2025, security researchers came across a stealer log file uploaded to a public Telegram channel, labeled as NewWlfrCloud. The file contained 69,516 records collected from compromised user devices by infostealer malware. Each record included an email address, a plaintext password, and a URL connected to a service or API endpoint the affected user had been logged into. The log was shared openly on Telegram, putting the stolen credentials within easy reach of anyone monitoring those channels for fresh data.

Why This Is Dangerous

When attackers get plaintext passwords alongside the URLs of the services those passwords protect, they have a direct path into real accounts. They do not need to guess, crack, or brute force anything. They can simply take each email and password pair, check which service URL it belongs to, and log right in. For victims, that could mean an attacker accessing their work email, cloud storage, project management tools, or financial accounts without any warning. The API host URLs in this breach are especially concerning for developers and businesses, since they can expose backend infrastructure to unauthorized access.

What Was Exposed in the NewWlfrCloud Stealer Log

• Email addresses
• Plaintext passwords
• API host URLs and service endpoint addresses

Why This Matters

Stealer logs from Telegram are one of the most common fuels for credential stuffing campaigns. Attackers take the email and password pairs and run them through automated tools that test them against banking sites, email providers, e-commerce platforms, and corporate systems all at once. Victems whose passwords appear here face a real risk of account takeover, fraudulent purchases, identity theft, and in workplace cases, data breaches that can affect an entire organisation. The longer it takes to discover your credentials are out there, the more damage can be done.

How Stealer Log Breaches Work

Infostealer malware typically arrives through phishing emails, fake game cracks, or trojanized software installers. Once it lands on a device, it quietly scans for saved passwords in web browsers, autofill data, session tokens, and any locally stored credentials. It packages everything into a neat log and sends it back to whoever deployed the malware. Those logs are then sold or freely posted on Telegram, where other cybercriminals download them and use the credentials for their own attacks.
