A prominent member of the Dogecoin (CRYPTO: DOGE) community, Mishaboar, has raised alarms about a potential wave of phishing attacks following a security breach at hardware wallet manufacturer Keystone. In an X post on Sunday, Mishaboar warned users to be on high alert for fraudulent emails, text messages, phone calls, and even physical mail. He drew parallels to past incidents involving Ledger and Trezor, where leaked customer data led to targeted scams. Mishaboar emphasized that the breach could link users' home addresses to their crypto holdings, increasing their vulnerability to scams.
Keystone acknowledged the breach in an X post on Saturday, apologizing to affected customers. The compromised data included names, contact information, shipping addresses, and order details. The company assured users that sensitive information such as payment card details, banking information, wallet recovery phrases, private keys, and passwords were not exposed. Keystone stated that it had blocked unauthorized access, fixed the vulnerability, and launched an investigation. The company is notifying affected customers via email.
Mishaboar also advised users to avoid sharing additional personal or family information on social media to mitigate potential privacy and security risks. Keystone warned that scammers might impersonate the company, offering fraudulent refunds, replacement devices, or order-related fixes. Users were urged to avoid clicking suspicious links, entering recovery phrases into unsolicited devices, or trusting unexpected communications claiming to represent Keystone.
