I recently investigated a Red Bull-themed phishing campaign that bypassed all email protections and landed in user inboxes.
The attacker used trusted infrastructure via post.xero.com and Mailgun, a classic living off trusted sites tactic. SPF, DKIM and DMARC all passed. TLS certs were valid.
This campaign bypassed enterprise grade filters cleanly... By using advanced phishing email analysis including header analysis, JARM fingerprinting, infra mapping - we rolled out KQL detections to customers.
Key Takeway: No matter how good your phishing protections are, determined attackers will find ways around them. That's where a human-led analysis makes the difference.

Researchers from The DFIR Report, in partnership with Proofpoint, have identified a new and resilient variant of the Interlock ransomware group’s remote access trojan (RAT). This new malware, a shift from the previously identified JavaScript-based [Interlock RAT](https://blog.sekoia.io/interlock-ransomware-evolving-under-the-radar/) (aka [NodeSnake](https://www.quorumcyber.com/wp-content/uploads/2025/06/20250416-Higher-Education-Sector-RAT.pdf)), uses PHP and is being used in a widespread campaign.

|Reference: [Ongoing Campaign Abuses Microsoft 365’s Direct Send to Deliver Phishing Emails](https://www.varonis.com/blog/direct-send-exploit)|
|:-|
**Key Points:**
* **Phishing Campaign:** Varonis' MDDR Forensics team uncovered a phishing campaign exploiting Microsoft 365's Direct Send feature.
* **Direct Send Feature:** Allows internal devices to send emails without authentication, which attackers abuse to spoof internal users.
* **Detection:** Look for external IPs in message headers, failures in SPF, DKIM, or DMARC, and unusual email behaviors.
* **Prevention:** Enable "Reject Direct Send," implement strict DMARC policies, and educate users on risks.

Could anyone share samples or real-world experiences about this *(for education and security monitoring)*?
