SANS Internet StormCast
SANS Stormcast Friday, May 1st, 2026: Libredtail; FreeBSD Dhclient Vuln; Linux Copy-Fail; @Sans_edu Detecting AI Pickling
Why It Matters
These vulnerabilities highlight how attackers can leverage outdated software and emerging AI supply‑chain risks to compromise critical systems, from firewalls to healthcare AI pipelines. For IT and security teams, understanding and mitigating these threats is essential to protect operational continuity and patient safety in an increasingly interconnected digital landscape.
Key Takeaways
- •RedTail exploits old PHP web vulnerabilities for crypto mining.
- •FreeBSD dhclient flaw enables remote code execution via DHCP spoofing.
- •Linux “copy‑fail” privilege escalation affects all recent kernels.
- •AI model pickle files can hide malicious code in healthcare.
- •Static scanning tools show inconsistent detection of malicious pickle models.
Pulse Analysis
The Stormcast episode highlighted three emerging threats that demand immediate attention.
RedTail malware now targets legacy PHP applications—such as outdated phpunit and directory‑traversal flaws—to install crypto miners, bypassing traditional SSH brute‑force defenses. Simultaneously, a remote‑code‑execution bug in FreeBSD’s dhclient lets attackers inject commands via spoofed DHCP lease files, a serious risk for firewalls and routers that still run default firmware.
Finally, the newly disclosed Linux “copy‑fail” flaw provides a reliable privilege‑escalation path across recent kernels, underscoring the urgency of kernel patches for shared‑hosting environments.
