Cisco's threat intelligence team. Has previously returned HTTP 403 on the routine UA (last seen 2026-05-06; recovered 2026-05-07 and confirmed working 2026-05-08). If WebFetch returns 403 again, route through `python3 tools/fetch_source.py url https://blog.talosintelligence.com/` rather than retrying. RSS at /rss/ also works. | 2026-06-20 full audit (v2.62): live=Y, drill=Y. FETCH → webfetch (listing) https://blog.talosintelligence.com/ then webfetch per-article slug URL; if WebFetch 403s, route bridge: python3 tools/fetch_source.py url https://blog.talosintelligence.com/ ; RSS at /rss/ also works. AVOID: Has intermittently 403'd the routine UA in the past — if WebFetch returns 403, go straight to the bridge rather than retrying the same UA..
