The 8.5 Million SkyULP Leak Could Unlock Your Bank and Email

HEROIC analysts identified a combolist labeled SKYULP PRIVATE ULP 05-17-2026 3 uploaded to a private Telegram channel on 17-May-2026. The file contained 8,557,869 records combining email addresses with plaintext passwords and the URLs of the sites those credentials were used on.

Why the SkyULP Leak Could Unlock More Than One Account

Because each password in this file sits in plaintext next to the exact site it belongs to, an attacker doesn't have to guess where to use it. And since most people reuse passwords across multiple services, a single exposed credential from this file can act as a skeleton key, unlocking email, banking, and social media accounts that were never part of the original leak.

What Was Exposed in This Leak

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters for 8.5 Million Exposed Accounts

A leak of this size gives attackers enough volume to run automated credential stuffing campaigns across major platforms at once. Anyone whose email appears in this file faces a heightened risk of account takeover, and because passwords often get reused, that risk can cascade into identity theft and financial fraud well beyond the original site the credentials were tied to.

How the SkyULP Combolist Was Assembled

Combolists like this one are built by pulling login pairs, an email or username with a password, from prior breaches, malware infections, and earlier leaks, then compiling them into one large file. SkyULP was packaged and distributed as a private upload through a Telegram channel, a common early step before combolists circulate more widely across dark web marketplaces.

Check If You Are Affected

If your email address is one of the 8,557,869 records in this leak, your password may already be in circulation. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including combolists like this one, so you can find out immediately and change any passwords tied to the exposure.
