2,530 Passwords Exposed in GROM Cloudfree Logs Leak

In January 2023, HEROIC analysts identified a stealer log file titled “GROM Cloudfree Logs” circulating on a public Telegram channel. The file exposed 2,530 records pulled directly from infected devices, including email addresses, plaintext passwords, and the URLs of the accounts those credentials unlocked.

Why the GROM Cloudfree Logs Leak Is Dangerous

Unlike a breach of a single company's database, this leak is a direct harvest from malware running on victims' own devices. That means the passwords are not hashed or scrambled in any way, they are stored in plaintext exactly as the victim typed them. Combined with the URL for each account, an attacker has a ready-made list of logins they can test immediately, no cracking or guessing required.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated account URLs

Why This Matters

Most people reuse the same password across several accounts, which means a single stolen login can open far more than one door. Attackers routinely take small logs like this one and feed them into automated tools that try each email and password pair against banking sites, email providers, and social media platforms. If even a few of the 2,530 entries in this log reuse a password elsewhere, those accounts are now at risk of takeover, financial fraud, or identity theft.

How Stealer Log Malware Works

A stealer log is the output of infostealer malware, malicious software that quietly installs itself on a victim's computer, often through a fake download, cracked software, or a malicious email attachment. Once running, it scans the browser for saved passwords, autofill data, and session information, then bundles everything into a text file and sends it back to the attacker. These logs are frequently packaged and shared on Telegram channels like the one where this file appeared, sold or given away to anyone looking for a fast way into someone else's accounts.
