2KK Aol Base Domain Leak: 1.98M Passwords Exposed, Act Now

A 2023 Stealer Log Labeled "2KK Aol Base Domain" Resurfaces With 1,980,876 Records

On February 7, 2023, HEROIC analysts identified a stealer log dataset shared by a Telegram user under the label "2KK Aol Base domain." The file held 1,980,876 records, and each one paired an email address with a plaintext password and the URL of the site that login was used on. The "Aol Base" naming points to a dataset built around accounts tied to AOL email addresses specifically.

Why This Stealer Log Is Dangerous

Nearly two million records in one file is a massive amount of ready-to-use access. Every password in this dataset is stored in plaintext, so there is no cracking or decoding required before it can be used to log in. Combined with the exact URL for each account, an attacker has a direct path into almost two million accounts without needing to guess a single detail.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs identifying the site each login was used on

Why This Matters

A dataset this large is exactly what credential stuffing tools are built for: feeding in millions of email and password pairs to automatically test them against banking sites, shopping accounts, and other services. If you have ever reused an old AOL email password anywhere else, this leak raises the risk of account takeover across every account that shares it. The URLs included in the file make each of those attempts faster and more precise.

How Stealer Logs Work

Stealer logs are generated by malware that infects a device and quietly copies saved passwords, browser autofill entries, and site URLs before sending everything to whoever controls the malware. People get infected through pirated downloads, fake software installers, and malicious attachments. Once collected, logs like this one are bundled together and traded in Telegram channels and dark web marketplaces, sometimes for years before HEROIC's analysts or others surface them publicly.

Check If You Are Affected

With almost 2 million records in this leak, checking your exposure is worth doing right now. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer logs like this one, and shows you exactly what has been exposed so you can secure your accounts immediately.
