What happened
Unit 42 published a set of research and threat briefs (May–Jun 2026) highlighting multiple high-impact cloud and supply-chain risks: universal bucket/namespace hijacking and bucket squatting that enable cross-CSP data redirection and exfiltration; a Vertex AI Python SDK flaw allowing cross-tenant RCE via model upload/bucket squatting; active exploitation of PAN-OS CVE-2026-0257; abuse of cloud logging services for defense evasion and visibility blindspots; large-scale credential attack campaigns; npm and AI-agent supply-chain threats; macOS-focused campaigns (FlutterShell) and new Tahoe 26 for
