New findings from ReliaQuest and Ontinue highlight how phishing campaigns are evolving into enterprise-grade operations.
Key Techniques
- Axios Abuse: Attackers exploit Axios HTTP tools to intercept, modify, and replay HTTP requests, capturing MFA codes, SAS tokens, and session cookies.
- Microsoft Direct Send: Weaponized to spoof trusted accounts and bypass secure email gateways. Axios + Direct Send yields a 70% phishing success rate.
- Salty 2FA Phishing Kits: Simulate six MFA methods (SMS, apps, calls, push, codes, hardware tokens) to sidestep authentication.
- Evasion Features: Cloudflare Turnstile checks, IP/geolocation filtering, Firebase hosting, dynamic branding, and domain-per-victim workflows.
Impact
- Executives in finance, healthcare, and manufacturing were first targeted, now expanded to general users.
- Campaigns use compensation-themed lures, fake OneDrive/Outlook portals, and malicious QR codes.
- The sophistication blurs the line between legitimate corporate workflows and fraudulent phishing pages.
Mitigation
- Disable or secure Direct Send if not required.
- Apply strict anti-spoofing and anti-phishing policies.
- Train employees to recognize malicious QR codes and MFA phishing lures.
- Block suspicious domains and continuously monitor traffic for anomalies.
