Design an end-to-end cloud-native forensic collection and analysis pipeline for a multi-account AWS and GCP environment that supports investigations across VMs, managed databases, object storage and serverless components. Specify collection methods (snapshots, API exports, CloudTrail/Audit Logs, VPC Flow Logs), secure collection and transfer, evidence immutability and chain-of-custody, scaling across accounts and regions, handling of encrypted resources, and how you would validate provider-supplied evidence.

A suspicious account in your AWS environment has been used to upload sensitive company files to an external S3 bucket. Describe a forensic plan to investigate and preserve cloud evidence: which AWS logs and artifacts you would collect (CloudTrail, S3 access logs, object metadata, VPC flow logs), how to preserve them for legal purposes, tools and APIs you would use to automate collection, and how you would correlate these cloud artifacts with on-host evidence.

You are the first responder to a report of suspected data theft at a corporate office and find a powered-off laptop on a desk. Describe the complete chain-of-custody process you would follow from initial contact through transfer to the forensic lab. Include physical handling steps, documentation practices, use of write-blockers and hashing, photographing and labeling evidence, digital imaging strategy, and how you would record each transfer or access to maintain legal defensibility.
