What happened
Unit 42 published a batch of high-impact cloud, supply-chain and endpoint findings. Key items: research into universal bucket hijacking/bucket squatting across major CSPs that can redirect cloud data streams and enable cross-tenant data exfiltration; a Vertex AI Python SDK vulnerability (pickle-based deserialization) allowing remote code execution via bucket squatting; abuse of cloud logging services for defense evasion and visibility reduction; guidance on mitigating large-scale credential attacks; active exploitation guidance and mitigations for PAN-OS CVE-2026-0257; and multiple supply‑side
