[security-observability] Daily Security Observability Report — 2026-06-12

[github-actions[bot]]

Executive Summary

This report covers the last 7 days (June 5–12, 2026) of agentic workflow security activity across the github/gh-aw repository. The firewall analysis captured 35 firewall-enabled workflow runs with an overall block rate of 0.51% — 9 blocked requests out of 1,754 total. Blocked traffic was concentrated in two workflows: Daily Fact About gh-aw (using an OpenAI/codex engine that attempted to access pypi.org, github.com, and api.github.com) and Delight (blocked a single proxy.golang.org Go module download). All other 33 workflows ran with zero blocked requests.

The DIFC integrity analysis found zero filtered events in the past 7 days — indicating that all tool calls passed integrity and secrecy checks without issue. No DIFC tuning actions are required at this time.

📈 Firewall Request Trends

Firewall activity shows strong variability across days, with a large spike on May 20 (735 blocked) and June 11 (197 blocked) driven by browser-automation-related domains (Google APIs, safebrowsing). Today (June 12) shows only 9 blocked requests — a significant improvement. The trend suggests tighter workflow configurations are taking effect over time.

Top Blocked Domains

Historically, the most frequently blocked domains are Google-related endpoints (content-autofill.googleapis.com, www.google.com, accounts.google.com) likely from browser-automation workflows. Today's blocks are narrowly scoped to package registries and the GitHub API from an OpenAI-engine workflow attempting unauthorized access.

• api.github.com:443 — 1 block (Daily Fact About gh-aw)
• github.com:443 — 1 block (Daily Fact About gh-aw)
• proxy.golang.org:443 — 1 block (Delight)
• pypi.org:443 — 6 blocks (Daily Fact About gh-aw)

🔒 Firewall Security Recommendations

1. Daily Fact About gh-aw — Network Policy Review: This workflow (using an OpenAI/codex engine) attempted to access pypi.org (6 times), api.github.com, and github.com, all of which were blocked. If Python package installation or GitHub API access is required, update its firewall policy to allow these domains. Otherwise, investigate whether the workflow is operating outside its intended scope.

2. Delight — Go module access: One blocked proxy.golang.org request suggests the Delight workflow attempted a Go module download. If Go compilation is part of its intended operation, add proxy.golang.org and sum.golang.org to its firewall allowlist.

3. Historical browser-automation traffic: The historical blocked domain list is dominated by Google APIs and Playwright CDNs. Ensure browser-automation workflows explicitly declare these domains in their network policies to reduce future blocks.

📈 DIFC Events Over Time

No DIFC integrity-filtered events were found in the last 7 days. All tool calls across all agentic workflow runs passed integrity and secrecy validation without any filtering activity.

💡 DIFC Tuning Recommendations

1. No action required: The DIFC system is operating cleanly with zero filtered events. Continue monitoring for future regressions.
2. Baseline established: This clean zero-event state provides a healthy baseline — any future filtered events should be investigated promptly to understand trigger patterns.
