Act Now: 299 abba.de_35k Plaintext Logins Leaked Online

HEROIC analysts found a plaintext combolist file named abba.de_35k circulating on Telegram, listing 299 records of email addresses, passwords, and URLs tied to abba.de logins. The file appeared on August 23, 2026, and every password in it sits in plaintext, meaning it can be used the moment someone opens the file. If your address could be inside, scan your email to check your exposure.

A list this small is still dangerous to the people in it: a short file is easy for an attacker to work through entry by entry, trying each email and password pair by hand against other sites. Because the passwords were never hashed or protected in any way, there is no step between finding the file and using it.

What's Inside the abba.de_35k File

• Email addresses: identify the account holder and give attackers a target for follow-up phishing.
• Plaintext passwords: usable immediately, with no cracking required.
• URLs: point to the exact login page each credential pair was captured for.

Why a Small File Can Still Cause Big Problems

With only 299 entries, this file is small enough that an attacker could manually test every pair against popular email providers, banking sites, and social media logins within a short time. If a password here was reused anywhere else, that account is exposed to takeover the moment someone tries it.

Combolists like this one are assembled from login pairs gathered off other leaks and dumps rather than pulled directly from one company's own systems, then shared or sold in bundles with the URLs attached so buyers know where to try them. That packaging is what turns a handful of old passwords into a ready-made attack list.

Responding to the abba.de_35k Leak

Scan your email to see whether your address is one of the 299 listed. Change the password anywhere you reused it, prioritizing your email account first since it can be used to reset everything else. This advice holds whether the address at risk is personal or tied to work.
