A security incident involving restaurant technology provider HungerRush highlights the growing risk of compromised communication infrastructure.
A threat actor sent extortion emails to restaurant patrons, claiming access to millions of data records associated with the HungerRush platform.
Technical observations include:
• Emails delivered through Twilio SendGrid infrastructure
• Messages passed SPF, DKIM, and DMARC authentication checks
• Access was reportedly gained via compromised third-party vendor credentials
HungerRush states the incident was limited to an email marketing service account, and that no passwords, payment card information, or sensitive personal data were exposed.
The event demonstrates how attackers can leverage trusted messaging infrastructure to launch extortion or phishing campaigns at scale.
