535,951 Records Sat Exposed for Months After Telegram Leak

Back on 12-Feb-2026, a file called "url_log 79" surfaced on Telegram, and buried inside it were 535,951 stolen login records that had been sitting exposed ever since. Months went by before this one landed on our radar, plenty of time for the data to circulate quietly among criminals.

Why This Is Dangerous

The longer a leak like this sits out there unnoticed, the more copies get made and traded. By the time most people find out their information is included, the data has allready passed through several hands, each one testing the credentials for reuse on banking, email, and shopping accounts.

What Was Exposed

• 535,951 records total
• Email Addresses
• Plaintext Password
• URLs for each affected site

Why This Matters

Time works against victims here. Every week that passes without a password change is another week that attackers get to try their luck automatically, running scripts that test old passwords across hundreds of websites at once. If your credentials were part of this 535,951-record dump, the clock has definately been ticking for a while now.

How Stealer Logs Work

These logs come from malware planted on a victim's own machine, quietly recording anything typed or auto filled in the browser. Once the infected device checks in with its controller, the stolen data gets packaged up and sold or shared, sometimes monthes after the original infection took place.

Check If You Are Affected

Rather than wonder how long your details might have been floating around, run a quick check with HEROIC's free breach scanner. It searches over 400 billion leaked records, including delayed leaks like this one, so you can catch up on time already lost.
