What happened

Atlas Quantum is a cryptocurrency investment platform. In August 2018 it suffered a data breach. The company said it became aware of the incident on August 25, and Have I Been Pwned added the data two days later.

Have I Been Pwned lists 261,463 accounts. The data includes names, phone numbers, email addresses and account balances. Some press reports gave slightly different counts, so this page uses HIBP's figure.

What the company said

Atlas Quantum said the attackers did not steal bitcoins held in custody or break into exchange accounts, and Avast also reported that no funds were taken. The company's disclosure gave few details about how the breach happened, and no source named the attacker.

What it means for you

Account balances are the sensitive part. Someone who knows your name, phone number and roughly how much crypto you hold has what they need to impersonate support staff or an exchange. Crypto-themed phishing and phone scams are common, and they work best when the caller quotes real figures.

Because the data contains phone numbers, watch for texts and calls. Scammers may also try a SIM swap, where they convince your mobile carrier to move your number to their SIM so they can receive your login codes.

No password data is listed for this breach, so changing a password isn't the first step here. Tightening up your phone number and any crypto accounts is.

What to do if you were in it

  1. 1

    Treat crypto 'support' calls and texts as scams

    Real platforms won't ask for your seed phrase, password or login codes. If someone quotes your balance and asks for any of these, hang up and contact the platform through its official site.

  2. 2

    Protect your phone number from SIM swaps

    Ask your carrier to add a PIN or passcode to your account. Use an authenticator app instead of SMS codes wherever you can.

  3. 3

    Turn on two-factor authentication

    Add 2FA to your email, banking and shopping accounts first. If an old password is still in circulation, a second step stops most takeover attempts.

  4. 4

    Check your exchange accounts

    Review recent activity and withdrawal addresses on any crypto account tied to the email you used on Atlas Quantum.

  5. 5
