BabaCloudLogs 467K Leak: 158,978 Accounts Face Takeover

HEROIC analysts traced a stealer log dump called BabaCloudLogs 467 K ULP LINE, uploaded to Telegram on June 29, 2025. The file contains 158,978 records in ULP format, meaning each line pairs a URL, a login email, and a plaintext password exactly as the malware captured it from an infected device.

The Real Consequence of a ULP Leak

ULP format is built for speed. Because the URL, email, and password sit together on a single line, criminals can feed the entire file straight into automated login tools without any extra work. The consequence is immediate. Within hours of a file like this circulating, victims can see failed login alerts, password reset emails they never requested, or charges on accounts they thought were secure.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs paired with each credential

Why This Matters

Once a password is confirmed working against its matching site, attackers move fast to lock out the real owner. If that password was reused, the damage doesn't stop at one account, it spreads through credential stuffing into email, banking, and shopping profiles, leading to account takeover, financial fraud, and identity theft that can take months to fully untangle.

How Stealer Logs Work

A stealer log begins the moment malware infects a device, often hidden inside a cracked program or a fake software update. The malware quitely pulls saved passwords straight from the browser, along with the site each one unlocks, then formats everything into ULP lines for easy reading. Files like BabaCloudLogs get organized, labeled by size, like the "467 K" in its name, and sold or shared on Telegram to whoever wants them.

Check If You Are Affected

Leaks like this have occured before and will keep happening as long as stealer malware keeps spreading. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, so you can see in seconds if your credentials showed up in BabaCloudLogs and act before someone else logs in first.
