AutoSys Cloud — set -x Leaked AWS Keys, $47K Bill
A script with set -x printed AWS keys to AutoSys stdout logs.
- AutoSys orchestrates cloud workloads via CMD jobs calling cloud CLIs, native cloud job types, or Broadcom Automic WA — central control plane for hybrid batch
- Key components: on-prem agent (executes cloud CLI commands), cloud service accounts (IAM roles), Automic WA (native cloud integration)
- Performance: Cloud API latency adds 50-500ms per call — set term_run_time accordingly (default 5 minutes may be insufficient)
- Production trap: Static AWS access keys on agent machines — keys leaked via log files, rotated never, compromise gives full cloud access
- Biggest mistake: Hybrid orchestration without timeout alignment — cloud API hangs, AutoSys job waits forever, downstream jobs never run
Modern enterprises run jobs both on traditional servers and in the cloud. AutoSys's cloud capabilities are like adding a remote control that reaches into AWS, Azure, and GCP — you can schedule and monitor cloud functions, containers, and services the same way you manage traditional on-premises batch jobs.
Enterprise batch environments don't exist purely on-premises anymore. Data pipelines increasingly span AWS S3, Azure Data Factory, GCP BigQuery, and containerised workloads. Broadcom has evolved AutoSys to handle these cloud and hybrid scenarios under the Broadcom Automic Workload Automation (AWA) umbrella, while maintaining backward compatibility with traditional AutoSys environments.
But cloud integration introduces new risks. Hardcoded AWS keys on agent machines can be leaked through job logs and never rotated. A Lambda that hangs for 10 minutes because of a cold start sits in RUNNING state, and AutoSys waits indefinitely because timeout isn't aligned. A network change that blocks outbound HTTPS kills all cloud jobs silently.
By the end you'll understand the pragmatic hybrid patterns (CMD + cloud CLI), the security requirements for cloud credentials, how to handle cloud service limits and timeouts, and the strategic direction of Broadcom Automic WA for cloud-native deployments.
Hybrid orchestration — the most common pattern
Most enterprises don't go fully cloud overnight. The most common pattern is hybrid: on-premises AutoSys jobs orchestrate a mix of traditional server-based jobs and cloud jobs. AutoSys acts as the central control plane for the entire workflow regardless of where each step actually executes.
--cli-read-timeout and --cli-connect-timeout to avoid indefinite hangs. Set term_run_time in JIL to 2x expected cloud job runtime.Broadcom Automic WA — the native cloud evolution
Broadcom's strategic direction is Automic Workload Automation (AWA), which extends AutoSys capabilities with: - Native cloud job types for AWS, Azure, and GCP resources - Container orchestration (Kubernetes, Docker) - RESTful API integration for triggering any cloud service - Modern web UI replacing the older WCC interface
If you're starting a new AutoSys-compatible deployment in 2026, Automic WA is worth evaluating alongside traditional AutoSys.
Practical cloud integration checklist
If you're extending your AutoSys environment to include cloud workloads, work through this checklist:
- IAM/Service accounts: Create dedicated service accounts in AWS/Azure/GCP for AutoSys agents with least-privilege permissions
- Credential management: Store cloud credentials securely — use AWS IAM roles (not static keys) where possible, Azure Managed Identity, or a secrets manager
- Network connectivity: On-premises AutoSys agents need outbound internet access to cloud APIs — check firewall rules
- Logging: Cloud-invoked jobs may log to cloud-native services (CloudWatch, Azure Monitor) — ensure stdout/stderr are also captured locally for AutoSys error log viewing
- Timeout alignment: Cloud services often have their own timeout limits — align AutoSys term_run_time with cloud service limits
The AWS Keys That Surfaced in stdout
AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY because the script had set -x enabled for debugging and printed all environment variables.export AWS_ACCESS_KEY_ID=AKIA... and export AWS_SECRET_ACCESS_KEY=.... The script also had set -x (bash debug mode) which prints every command and variable expansion to stdout. The stdout was captured by AutoSys to a network file share. A developer, debugging an unrelated issue, copied the log file to their local machine and later committed it to a public GitHub repository by mistake. The keys were exfiltrated within hours. The attacker used them to launch EC2 instances for cryptocurrency mining. The bill reached $47,000 before the keys were revoked.set -x from production scripts. Used structured logging without secrets.
4. Implemented secret scanning in CI to prevent keys from being committed to Git.
5. Rotated all static keys quarterly and set up CloudTrail alerts for anomalous API calls.
6. Added IAM policy condition: aws:SourceIp to restrict API calls to the agent's IP address.- Never hardcode cloud credentials in AutoSys job scripts. Use IAM roles, instance profiles, or managed identities.
- Job stdout/stderr files are not secure. Any secrets printed to stdout will be stored in clear text in the Event Server or log files.
- Rotate service account keys at least every 90 days, or better, eliminate long-lived keys entirely.
- Implement least-privilege IAM policies. The compromised key should only have permissions for the specific Lambda, not EC2.
