Act Now: acsinc.net – 18.210 emails uploaded by a Telegram User

In June 2026, HEROIC analysts found a file labeled "acsinc.net - 18.210 emails" posted to a Telegram channel, containing 18,210 exposed records. Each entry pairs an email address with a plaintext password and the login URL it was captured from, the standard structure of a stealer log pulled from infected devices.

Why You Need to Act Now, Not Later

Every credential in this file is a working email and password pair sitting in plain text, ready for anyone who downloads it to try logging in immediately. There is no waiting period before this data becomes dangerous, the moment it starts circulating on Telegram, the accounts inside it are at risk. If you have any connection to acsinc.net or reuse passwords across accounts, the time to check and change your credentials is now, not after something goes wrong.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs tied to each credential pair

Why This Matters

With over 18,000 working logins in this file, it is built for credential stuffing, automated attempts to try the same email and password combination across banking, shopping, and other accounts. Anyone who reused a password from this list elsewhere faces a real risk of account takeover, and depending on which other services share that password, identity theft or financial fraud can follow.

How a Stealer Log Like This Gets Built

Malware infects a device, often through a pirated download or fake installer, and quietly copies every saved browser credential it can find. Those records get bundled together and posted to Telegram, exactly how this 18,210-record file tied to acsinc.net ended up circulating.

Check If You're Affected

Do not wait to find out if you are exposed. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, so you can check right now whether your email and password are part of this leak and change them before someone else does.
