Payment email with malware attached

Sent from hacked Sendgrid account

If you come across this sort of email, don't be concerned and don't attempt to open the attachment. Forward it to your family, coworkers, and friends so that they can benefit from it.

We believe SendGrid's account was compromised based on the email's header, which contains Spf, Dkim, and Dmarc passed. We'd had a similar situation with Mailjet / Mailgun before; our account was hacked. (We suspect that it is an inside job, as we have all security in place and the hacker only used our account to send out phishing emails with their database. This resulted that us clearing up our database in Mailjet and switching to another provider). As this kind of act will further cripple the business and reputation.

What is SPF

Sender Policy Framework is an email authentication method designed to detect forging sender addresses during the delivery of the email. SPF alone, though, is limited to detecting a forged sender claim in the envelope of the email, which is used when the mail gets bounced.


What is DKIM

DomainKeys Identified Mail is an email authentication method designed to detect forged sender addresses in email, a technique often used in phishing and email spam. DKIM allows the receiver to check that an email claimed to have come from a specific domain was indeed authorized by the owner of that domain.


What is Dmarc

DMARC is an email authentication protocol. It is designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing.
