The filnet.es Leak Exposed 23,947 Spanish Email Accounts

In June 2026, HEROIC analysts identified a combolist tied to the Spanish domain filnet.es after it was uploaded to a Telegram channel. Dated June 10, 2026, the file contains 23,947 records, each pairing an email address with a plaintext password and an associated URL. A Large-Scale Leak Focused on Spanish Email Accounts With nearly 24,000 records tied to a single Spanish domain, this combolist represents a sizable, geographically focused batch of credentials rather than a scattered mix pulled from many unrelated sources. That concentration makes it easier for an attacker to run a targeted campaign against people connected to filnet.es specifically, rather than spreading effort across accounts with no relationship to each other. What Was Exposed in the filnet.es Combolist Email addresses Plaintext passwords Associated URLs Why This Matters Because these passwords are stored in plaintext, anyone who obtains the file can read them directly and begin credential stuffing right away, testing each of the 23,947 pairs against banking sites, other email providers, and social media accounts. Anyone who reused a filnet.es password elsewhere faces real risk of account takeover, identity theft, and financial fraud. How Combolists Like This One Get Made A combolist is a compiled file of email addresses matched with passwords, typically gathered from smaller breaches, phishing campaigns, or malware that harvests saved logins from infected devices. Once compiled, files like this circulate on Telegram, where anyone looking for a working set of accounts can pick them up.
