NovaCookies Campaigns Abuse Genuine Docusign Notifications to Steal Microsoft 365 Sessions

Security researchers disclosed NovaCookies, a subscription-based adversary-in-the-middle phishing toolkit priced at $320 per month that proxies Microsoft 365 sign-ins and harvests authenticated sessions. The campaigns abuse genuine DocuSign notifications to lure targets into the phishing flow.

Why it matters: Microsoft 365 administrators and users face session hijacking attacks that bypass standard authentication; organizations should monitor for DocuSign-themed phishing and enforce additional verification before granting access to sensitive resources.
