Lead-2025-05-07 File Quietly Leaked 13 Plaintext Email Logins

If your email turns up in a file labeled Lead-2025-05-07, it means HEROIC analysts found it sitting among just 13 records in a small combolist, paired with a plaintext password and the URL the login was created on. Being one of only 13 does not make the exposure less serious, since the password is stored in fully readable form and can be used the moment someone opens the file. The upload is dated to May 2025. Scanning your email is the only way to know for certain whether you are one of those 13 records.

What Being in a Small File Actually Means

A short file often means a more targeted list rather than a random sweep, which can make it more likely that whoever holds it will actually try each credential rather than let it sit unused. Either way, the outcome for anyone in the file is the same, a working, unencrypted password in someone else's hands.

What the Lead-2025-05-07 File Contains

• Email Addresses. Serve as a verified contact for phishing attempts and for matching against other leaked lists.
• Plaintext Password. Readable and usable immediately, with no cracking required.
• URLs. Identify the exact site or service each credential pair was meant for.

Why Thirteen Records Can Still Mean Real Damage

If the password in this file has been reused for an email account or an online banking login, the size of the file makes no difference to how easily an attacker can take over those accounts. A single working password is often enough to reach several linked services at once.

How a File This Small Comes Together

A combolist is built by gathering email and password pairs from various sources into one file so they can be tried against websites in bulk, regardless of how many entries it ends up holding. According to HEROIC analysts, smaller files like this one frequently get absorbed into larger combolists over time.

What To Do If You Are One of the 13

Start with a scan your email to check whether your address is included in this file. If it is, change that password everywhere you have used it and turn on two-factor authentication for your email account. This matters equally for a personal or work email address.
