62k Private Combo Leak: What Hackers Can Do With Your Logins

62k Private Combo Stealer Log: 53,243 Records Exposed

On 08-Jan-2023, HEROIC analysts identified a file called "62k private Combo" being shared by a Telegram user in a channel dedicated to trading stolen login data. Despite the "62k" in the name, the file HEROIC catalogued actually contained 53,243 records, each one pairing an email address with a plaintext password and the URL of the site the credentials were captured on.

Why This Stealer Log Is Dangerous

What matters here is what an attacker can actually do with this data, and the answer is: log straight into an account with no extra work. Because each record already lists the exact website the email and password combination belongs to, there is no need to guess or test the credentials elsewhere first. With the passwords stored in plaintext, an attacker can copy and paste a login pair directly into the matching site and be in.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites the credentials were used on

Why This Matters

With 53,243 working login pairs in hand, an attacker can run automated credential stuffing at scale, quietly testing each email and password combination against banking, email, and shopping accounts to find where people reused the same password. Anyone in this file who has not changed the exposed password since 2023 is still at risk of account takeover today, since old stealer log data continues to circulate and get reused years after it first leaked.

How Stealer Logs Work

Stealer logs are created by malware that infects a victim's device and quietly harvests everything saved in the browser: usernames, passwords, and the sites they belong to. That data is bundled into a file, sometimes labeled as a "combo" list, and shared or sold through Telegram channels and dark web forums where other criminals pick it up and put it to use, often long after it was first collected.

Check If You Are Affected

Because stealer log data like this can resurface and get reused years later, it is worth checking your exposure now. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including older stealer logs like this one, so you can confirm whether you are affected and update any passwords that are still at risk.
