A 94 Record Stealer Log Creates Chained Account Takeover Risk

HEROIC analysts found a stealer log file with 94 plaintext passwords tied to matching emails and login pages. None of the passwords are hashed, so anyone holding the file can use them right away, dated June 9, 2020.

Ninety four is the largest count in this particular batch of small stealer logs HEROIC has been tracking, and plaintext means there's no extra step between finding a password and using it. If you want to check whether your own email turns up in a file like this, scan your email for free.

Why Plaintext Passwords Raise the Stakes

Weak hashed passwords still need cracking before they're useful. Plaintext skips that step entirely, the password sitting in the file is the exact password someone typed into their browser. That turns a list of 94 records into 94 accounts an attacker can log into today, not accounts they might eventually get into with enough computing time.

What Was Exposed

• Email addresses, used to identify which account each password belongs to
• Plaintext passwords, readable and usable the moment they're pulled from the file
• URLs, showing exactly which login page each password was captured from

How This Turns Into a Chain of Account Takeovers

A single reused password can unlock more than the one account listed in this file. If any of these 94 people typed the same password into their email, their banking app, or a work login, that one exposed password becomes a key to several doors at once. Attackers routinely test a stolen password against other common services once they have it, a tactic that turns one small leak into a much bigger problem for the person affected.

How Malware Harvests Passwords Like These

This kind of file comes from an infected device, not a breached company server. Malware, often hidden inside a cracked application or a fake software update, quietly reads the password manager built into the victim's browser and copies out everything saved there along with the matching site addresses. The results get bundled into a file and distributed, in this case through Telegram.

Time to Check These 94 Passwords Against Your Own?

Take a moment to scan your email and see whether it appears in this file or any other HEROIC has on record. If it does, change that password immediately, and change it everywhere else you may have reused it too. This matters equally for personal inboxes and work email accounts.
