STARLINKULP Stealer Log Leak: 8M Passwords, Emails Exposed

STARLINKULP Stealer Log Exposes Over 8 Million Records

In September 2025, HEROIC analysts identified a stealer log file circulated by a Telegram user under the name "STARLINKULP." The file was initially advertised as containing around 11 million entries, but our verification confirmed the actual number at 8,032,573 records. Each entry pairs an email address with a plaintext password and the URL of the site the credentials were used on.

Why the STARLINKULP Leak Is Dangerous

Because the passwords in this log were stored and leaked in plaintext, anyone who obtains the file can log into an account immediately, with no cracking or guessing required. Each record also includes the URL where the credential pair was captured, which tells an attacker exactly which website or service to target. That makes this dataset especially useful for automated login attempts against banking, email, and shopping accounts.

What Was Exposed in the STARLINKULP Log

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters for Anyone in the STARLINKULP Data

Plaintext credential pairs like these are the raw material for credential stuffing attacks, where criminals feed leaked email and password combinations into automated tools that test them against hundreds of other websites. If you reuse passwords across accounts, a single exposed login can lead to account takeover, drained financial accounts, or full identity theft. The presence of exact login URLs makes it easier for attackers to skip straight to the accounts most likely to work.

How a Stealer Log Like This Gets Created

Stealer logs come from malware that infects a victim's device and quietly collects saved browser passwords, autofill data, and session information before sending it back to the attacker. That stolen data is then packaged into a file, like the one behind this STARLINKULP leak, and sold or shared on dark web forums and Telegram channels. Because the malware captures whatever was saved in the browser at the time of infection, these logs often contain accurate, currently valid passwords rather than old, already-changed ones.

Check If You Are Affected by the STARLINKULP Leak

With more than 8 million credential pairs involved, this leak is large enough that many people won't know their information is included until they check. HEROIC's free breach scanner searches a database of over 400 billion leaked records, including this STARLINKULP log, so you can quickly see if your email address turns up and take action before someone else uses your password first.
