The Mail Access Valid 100 Leak Put 640 People at Risk of Account Fraud

HEROIC analysts identified this stealer log on 17-Dec-2025. The breach exposed 640 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as Mail Access Valid 100, uploaded by a Telegram user.

Why This Is Dangerous

The Valid 100 label in this breach name means every credential in the file has been tested and confirmed as active. All 640 email accounts in this stealer log are fully accessible to criminals right now. Unlike raw data dumps where some records may be outdated, this list contains only working logins that can be exploited immediately.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs (website addresses where each credential was captured)

Why This Matters

When 640 verified email accounts are exposed in the Mail Access Valid 100 breach, every affected individual faces direct risk of account fraud. Criminals can use email access to trigger password resets on banking apps, intercept one-time security codes, and take control of accounts on shopping and social media platforms. Identity theft becomes easier when an attacker has full access to a victim's inbox, where much of their digital life is managed.

How a Stealer Log Works

Stealer malware is typically spread through fake software installers, cracked games, or phishing emails. Once installed on a device, it runs invisibly and copies all saved login credentials from the browser. These are then transmitted to the attacker, verified for validity, and packaged into lists like this one, which are shared in criminal communities.
