+### AWS Lambda – VPC Egress Bypass
+
+Force a Lambda function out of a restricted VPC by updating its configuration with an empty VpcConfig (SubnetIds=[], SecurityGroupIds=[]). The function will then run in the Lambda-managed networking plane, regaining outbound internet access and bypassing egress controls enforced by private VPC subnets without NAT.

+
+### AWS Lambda – Runtime Pinning/Rollback Abuse
+
+Abuse `lambda:PutRuntimeManagementConfig` to pin a function to a specific runtime version (Manual) or freeze updates (FunctionUpdate). This preserves compatibility with malicious layers/wrappers and can keep the function on an outdated, vulnerable runtime to aid exploitation and long-term persistence.

+### AWS Lambda – Log Siphon via LoggingConfig.LogGroup Redirection
+
+Abuse `lambda:UpdateFunctionConfiguration` advanced logging controls to redirect a function’s logs to an attacker-chosen CloudWatch Logs log group. This works without changing code or the execution role (most Lambda roles already include `logs:CreateLogGroup/CreateLogStream/PutLogEvents` via `AWSLambdaBasicExecutionRole`). If the function prints secrets/request bodies or crashes with stack traces, you can collect them from the new log group.

+### AWS - Lambda Function URL Public Exposure
+
+Turn a private Lambda Function URL into a public unauthenticated endpoint by switching the Function URL AuthType to NONE and attaching a resource-based policy that grants lambda:InvokeFunctionUrl to everyone. This enables anonymous invocation of internal functions and can expose sensitive backend operations.

+
+### AWS Lambda – Event Source Mapping Target Hijack
+
+Abuse `UpdateEventSourceMapping` to change the target Lambda function of an existing Event Source Mapping (ESM) so that records from DynamoDB Streams, Kinesis, or SQS are delivered to an attacker-controlled function. This silently diverts live data without touching producers or the original function code.

+
+### AWS Lambda – EFS Mount Injection data exfiltration
+
+Abuse `lambda:UpdateFunctionConfiguration` to attach an existing EFS Access Point to a Lambda, then deploy trivial code that lists/reads files from the mounted path to exfiltrate shared secrets/config that the function previously couldn’t access.
