Attackers Can Now Use 430,136 Stolen Logins From SunCloudNew

With SunCloudNew 1639 - 573 K ULP now circulating on Telegram since February 27, 2026, attackers don't need to do any additional work to start using the 430,136 credentials inside. Every email, password, and matching URL is already sitting there, ready to plug into automated tools within minutes of downloading the file.

Why This Is Dangerous

What attackers can do with a file like this is the real concern. They can run the entire list against email providers, banking portals, and shopping sites in an automated sweep, testing thousands of combinations an hour without lifting a finger after the script starts. Some criminals even recieve a copy of this kind of data through private trading channels before it's ever posted publicly.

What Was Exposed

• Email addresses tied to each infected device
• Plaintext passwords with no protection
• URLs identifying exactly which accounts the logins unlock

Why This Matters

A working password paired with a known URL takes almost all the effort out of hacking an account. Attackers don't have to guess what service a person uses, it's already labeled for them, so the only real barrier left is whether the victim reused that password anywhere else, wich makes checking every account neccessary.

How Stealer Logs Work

This data comes from malware that infects a device quietly, often bundled inside pirated software or a fake crack, and then scrapes every saved password and autofill entry it can access. Once collected, the haul gets sent back to the attacker's server, packaged into a ULP file, and shared or sold, sometimes for free to attract attention on Telegram channels like the one hosting SunCloudNew 1639.

Check If You Are Affected

Don't assume you're safe just because you haven't heard anything. HEROIC's free scanner checks your email against more than 400 billion breached and leaked records, including stealer logs like SunCloudNew 1639, so you can confirm your exposure and reset any passwords that need it.
