The BradMax 400 March Stealer Log Means Someone Could Be Logging In Right Now

HEROIC threat intelligence analysts catalogued the BradMax 400 March stealer log on March 5, 2023, the day after a Telegram user uploaded it to a public channel. The file contains 6,432 credential records pulled from roughly 400 infected machines, each record pairing an email address with a plaintext password and the URL of the site where that password works.

Why the BradMax 400 March File Is Dangerous

Imagine a stranger sitting at another keyboard, a cup of coffee nearby, working through a list of your passwords one by one. That is effectively what this leak enables. Every line in the BradMax 400 March file was captured from a real user's browser while they were signed in. The credentials worked at the moment they were stolen, and many still work now.

There are no hashes to crack and no salts to defeat. Plaintext passwords plus matching URLs produce one of the fastest routes to a working login.

What Was Exposed in BradMax 400 March

• Email addresses tied to real personal and business accounts
• Plaintext passwords with no encryption in the way
• URLs pointing to the login page each password unlocks

Why This Matters

Imagine the same attacker pulling up a victim's bank, shopping, or email account at two in the morning. Every session log, every saved card, every family contact, now visible to someone who was not invited. That is the practical outcome of a stealer log: silent account takeover, identity theft, and financial fraud executed while the victim sleeps.

Credential stuffing tools multiply the problem by running the same 6,432 records against hundreds of other services, turning one captured login into access to dozens.

How a Stealer Log Like BradMax Works

Infostealer malware enters a computer through cracked software, malicious ads, phishing attachments, or fake browser updates. Once running, it reads saved browser credentials, cookies, autofill data, and sometimes cryptocurrency wallet files, then writes everything into a plain text log.

The log is sent back to the malware operator. Those operators then bundle hundreds or thousands of logs into packages like BradMax 400 March and push them into Telegram channels where the data is passed around within minutes of arrival.
