Dark Web Intel: 5,335 Login Credentials Found in MailAccessCombos_3

HEROIC's dark web intelligence team identified a combolist titled "MailAccessCombos_3" uploaded to Telegram on August 1, 2026. The file contains 5,335 records, each combining an email address with a plaintext password and the URL the login belongs to.

What Our Dark Web Analysts Found

MailAccessCombos_3 surfaced in a Telegram channel that regularly circulates freshly compiled combolists. Because the passwords are stored in plaintext and already matched to specific URLs, the file requires no further processing before an attacker can start testing the credentials against real login pages.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

Dark web monitoring exists because lists like this one rarely stay in one place. Once a combolist like MailAccessCombos_3 is posted, it can be copied, resold, and redistributed across other channels and marketplaces, widening the pool of attackers who have access to it. Anyone in this list faces the risk of credential stuffing and account takeover for as long as the file continues to circulate.

How Combolists Like This Get Assembled

Combolists are typically built from a mix of older breaches, phishing hauls, and stealer log data, then reformatted into simple email, password, and URL entries. Lists like MailAccessCombos_3 are numbered and versioned, suggesting the uploader distributes these regularly as new source data becomes available.
