What Attackers Can Do With the Filterix Breach’s 20,926 Records

Filterix, an online service, had its customer records exposed in a breach dated May 30, 2026, pairing phone numbers with email addresses and full names across 20,926 records. That combination gives a complete contact profile for each person on the list, not just an isolated detail. Scanning your email is the only way to know if your own record is one of them.

What Attackers Can Do With a Full Contact Profile

A phone number alone invites a scam call. An email alone invites a phishing attempt. Together with a full name, both channels become far more convincing, since the message can open by addressing you directly and reference a contact method you actually use, making it easier to pass as something legitimate.

What Was Exposed

• Phone Number: enables scam calls or texts that can reference the person by name to sound credible.
• Email Address: gives a second channel for the same kind of targeted phishing attempt.
• First Name: lets a scam message open with a personal greeting instead of a generic one.
• Last Name: completes the identity, making contact feel like it comes from someone who already knows you.

Why This Matters

No passwords were part of this exposure, so there's no direct account takeover risk from this file alone. The real danger is in how convincingly this data can be used to open a conversation, whether that's a call, a text, or an email built to look like it's coming from Filterix itself.

How This Breach Type Works

This was a database breach, meaning the records came directly from Filterix's own systems rather than from malware on a customer's device. Whoever accessed it pulled the stored customer data as it existed on the server and distributed a copy of it on Telegram.

Were You a Filterix Customer on This List?

Start with the scan your email tool above to check your exposure. Since no passwords were included, there's no login here to reset, but watch for calls, texts, or emails that reference Filterix or use your name to seem legitimate. Apply the same caution whether the contact reaches a personal number or a work one.
