Crypto Users Exposed: The Everycoin Breach Leaked 20K User Records

HEROIC analysts discovered the Everycoin database breach while monitoring dark web forums in November 2021. The US-based cryptocurrency platform had 19,954 user records exfiltrated from its database, exposing email addresses, phone numbers, and full names. The data recieved attention from threat actors who specialize in cryptocurrency-focused social engineering, making this breach particularly dangerous for affected users who may still hold digital assets.

How Phone Numbers and Emails from Crypto Platforms Fuel SIM Swapping and Fraud

Cryptocurrency users are high-value targets for attackers armed with phone numbers and email addresses. With this data, criminals can attempt SIM swapping attacks, taking over a victim's phone number to intercept two-factor authentication codes and drain crypto wallets. Full names paired with email addresses also make phishing campaigns accessable to even low-skill attackers, who impersonate the platform or related services to steal credentials and funds.

What Was Exposed in the Everycoin Breach

• Email Address
• Phone Number

Why Cryptocurrency Platform Breaches Create Lasting Financial Risk

Unlike traditional financial breaches, compromised crypto user data can lead directly to irreversible financial losses. SIM swapping attacks enabled by leaked phone numbers have been used to steal millions in cryptocurrency from individual users. Even years after this breach occured, the data continues to circulate among threat actors who target crypto holders. Credential stuffing, account takeover, identity theft, and targeted phishing remain active risks for anyone whose information was exposed in the Everycoin incident.

How Database Breaches Work

A database breach occurs when attackers gain unauthorized access to a platform's stored records by exploiting vulnerabilities such as SQL injection, unpatched software, or misconfigured APIs. Once inside, they silently extract user data and distribute it across underground markets. For cryptocurrency platforms, this type of breach is seperate from blockchain-level attacks but equally damaging, as personal data enables social engineering that bypasses technical security controls entirely.
