Domain registrar Namecheap had its email account hacked on Sunday evening, sparking a flood of MetaMask and DHL phishing emails that attempted to steal recipients’ personal information and cryptocurrency wallets.

The phishing campaigns began around 4:30 p.m. ET and originated from SendGrid, an email platform historically used by Namecheap to send renewal notices and marketing emails.

After recipients started complaining on Twitter, Namecheap CEO Richard Kirkendall confirmed that the account has been compromised and they have disabled email through SendGrid while they investigate the issue.

Kirkendall also said they believe the breach may be related to a December CloudSek Report on Mailgun, MailChimp, and SendGrid API keys exposed in mobile apps.

A deluge of emails

Phishing emails sent in this campaign impersonate DHL or MetaMask.

The DHL phishing email pretends to be an invoice for the delivery costs needed to complete the delivery of a package. Although BleepingComputer did not receive this email, we were told that the embedded links led to a phishing page attempting to steal the target’s information.

BleepingComputer received the MetaMask phishing email, which claims to be a KYC (Know Your Customer) verification required to prevent the suspension of the wallet.
