The StarX Breach Was Dated March 2026. Part 4 Just Surfaced.

The data in StarX_ULP_08.03.2026_Part_4 carries a leak date of 8 March 2026, but HEROIC analysts only cataloged this fourth installment recently, alongside the rest of the March StarX series. The file adds 2,593,540 records of email addresses, plaintext passwords, and matching URLs, bringing the four-part March series to more than 19 million combined exposed credentials.

Why the Delay Between Leak and Discovery Matters

A gap between when data like this is first compiled and when it becomes widely known gives attackers a head start. Anyone holding the file since March has had months to test the credentials before most of the people affected ever hear about it. That is exactly why identifying and cataloging leaks like this one, even after the fact, still matters: it closes the window during which victims remain unaware.

What Was Exposed in StarX ULP Part 4

• Email addresses
• Plaintext passwords
• URLs identifying the exact site each login unlocks

Why This Matters for the 2.59 Million Records in This Part

Every credential pair in this file can be used immediately for credential stuffing, feeding logins directly into the sites named in the accompanying URLs. If any of these accounts still use the same password today, months after the original leak date, the risk of account takeover, identity theft, or financial fraud remains just as real as it was the day the data was first compiled.

How the Full StarX ULP Series Came Together

Part 4 completes what is now a four-part StarX series spanning February and March, each file built the same way, stolen credentials organized into the URL, login, password format that makes them instantly usable. Splitting a large dataset like this across multiple dated uploads is common practice on Telegram, letting a single collection of stolen data circulate in waves over an extended period.

Check If Your Data Is Still Exposed

Months can pass between when a leak like this happens and when it surfaces publicly, which is exactly why checking your exposure now matters. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including every part of the StarX series, so you can find out if your credentials were exposed and update them today.
