  "account": "Your team possesses a well-developed detection system, replete with rules honed from experience with genuine incidents such as suspicious parent-child process trees, LSASS access patterns, and lateral movement over SMB. However, when a project is initiated in AWS and an access key is stolen from a CI configuration file, the attack transpires entirely within CloudTrail. The attack is characterized by a series of IAM API calls, devoid of any associated process, host, or EDR agent. Traditional detection rules presume the existence of a process tree, but this particular attack lacks such a component. Instead, it generates an audit log, which goes undetected by your current detection strategies. This scenario is not merely hypothetical; it represents a common predicament in cloud-native attacks due to the distinct nature of signals compared to those typically handled by host and network detection engineering. The attack proceeds as follows: a compromised IAM credential initially verifies its validity through the sts:GetCallerIdentity call, followed by a rapid series of iam:List* and iam:Get* calls to enumerate roles, policies, and users. While these activities on a host may resemble mundane operations like \"whoami\" and directory listings, their occurrence in CloudTrail warrants attention if they are abnormal for a developer's typical behavior. The subsequent escalation often does not involve a stolen root key but rather a strategic use of the granted permissions, such as iam:PassRole combined with lambda:CreateFunction and lambda:InvokeFunction, to elevate privileges by passing an over-permissioned role to a newly created function and invoking it. This method enables privilege escalation without relying on unauthorized credentials. The attack's detection requires an equivalent level of meticulousness as traditional detection rules, but it must focus on the unique sequence of IAM API calls, the accompanying reconnaissance pattern, and the combination of permissions that facilitate escalation. These principles are applicable across various cloud service providers, including AWS, Azure, GCP, and Kubernetes, each maintaining distinct versions of reconnaissance calls and permission combinations that can be leveraged for effective detection. Codelivly's \"Cloud Detection and Response Book: AWS, Azure, GCP\" is designed to translate the detection engineering expertise you already possess for traditional systems into actionable detection logic for IAM, activity, and audit logs across multiple cloud environments.",
  "summary": "Your team has a mature detection stack. Years of rules tuned against real incidents: suspicious parent-child process trees, LSASS access patterns, lateral movement over SMB. Then someone spins up a project in AWS, an access key gets phished out of a CI config file, and the actual attack unfolds entirely inside CloudTrail: a sequence of IAM API calls with no process, no host, no EDR agent anywhere…",
