warga_jakarta_selatan Leak Puts 494,697 Passwords at Risk of Reuse

494,697. That's how many email and plaintext password pairs HEROIC analysts found inside a combolist labeled warga_jakarta_selatan, dated 26 Mar 2026. It's the largest of three similarly labeled files logged this week, and like the others, the name is just a file label, not an indication of who is in the data or where they live. Scan your email to check whether your address is one of the 494,697.

What a File of Nearly 500,000 Records Means in Practice

A combolist this size is typically run through automated credential stuffing tools that test every pair against dozens of services in sequence. The consequence isn't abstract: each successful match becomes one more account an attacker can log into directly, without needing to break a password.

What's Inside the warga_jakarta_selatan File

• Email addresses: the account tied to each stolen password.
• Plaintext passwords: readable and immediately usable, no cracking required.
• URLs: the login pages each credential pair is tied to.

Why the Consequences Extend Past One Login

A single compromised password rarely stays contained to one account. If it's reused for email, banking, or shopping, one match in this file can cascade into account takeover, unauthorized purchases, or a locked-out inbox that's hard to recover.

How a Combolist This Size Gets Built

Large combolists come from merging many smaller leaks and stealer log outputs into a single file, organized for use in mass login attempts. The size reflects how much data has been combined, not a single point of compromise at one company.

Stop the Chain Before It Starts

Run a free scan your email to check your exposure in this file. If you're listed, change that password on every account where you've reused it, prioritizing email and financial logins, and move to unique passwords per site from here on. This applies equally to work and personal email addresses.
