AWS Bedrock AgentCore Code Interpreter allows attackers to exfiltrate sensitive data using DNS queries even when running in “Sandbox” mode — and AWS says this is intended behavior, not a vulnerability. Security researchers from Phantom Labs and Sonrai Security have independently demonstrated that DNS resolution capabilities bypass sandbox isolation, enabling credential theft, S3 bucket enumeration, and full command-and-control channels through a protocol that every firewall permits by default. Key Takeaway: If your organization deploys AI agents with code execution capabilities in AWS, the word “sandbox” does not mean what you think it means — DNS-based exfiltration works regardless of network mode, and overpermissioned IAM roles turn a DNS covert channel into a full data breach. ...

Google completed its $32 billion acquisition of cloud security company Wiz on March 11, 2026 — the largest cybersecurity acquisition in history.

For network engineers managing multi-cloud environments, this deal signals that cloud security posture management is no longer a separate concern from network infrastructure — it’s converging into the hyperscaler platforms you already manage. ...
