abv.bg All Valid: 51 Verified Passwords Leaked on Telegram

A Small, Verified Stealer Log Labeled "abv.bg all valid"

HEROIC analysts flagged a stealer log named "abv.bg all valid," uploaded to a Telegram channel on 10-May-2023. This is a small file: it contains 51 records, each pairing an email address with a plaintext password and the URL of the site the credentials were captured from. The "all valid" label in the name suggests these logins were checked and confirmed to work before being shared.

Why the abv.bg all valid Stealer Log Is Dangerous

Small does not mean harmless here. If these 51 accounts really were verified as working, that removes the one thing that usually slows an attacker down: not knowing which stolen credentials still function. Each record already ties a specific email and password to the exact website it unlocks, and because the passwords are in plaintext, anyone with the file can read and use them immediately.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the websites where the credentials were used

Why This Matters

With a small, reportedly verified list like this one, the people included face a fairly direct risk of account takeover, since each record hands an attacker a login that's already been confirmed to work. It also feeds credential stuffing: if the password in this file was reused on any other account, that account is at risk too, even though it has nothing to do with this particular leak.

How Stealer Logs Work

Stealer logs are produced by malware that infects a device, quietly pulls saved passwords and active browser sessions, and sends everything back to whoever controls the malware. Some sellers then go a step further and manually check, or "validate," which of those stolen logins still work, which is likely what the "all valid" label on this file refers to. Verified lists like this one are considered more valuable and are traded on Telegram, exactly where HEROIC analysts found it.

Check If You Are Affected

Even with only 51 records, it's worth checking rather than assuming this doesn't involve you. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, and tells you immediately if you've been exposed. If you get a match, change that password right away and avoid reusing it anywhere else.
