# Feodo Tracker — claimed 5-minute regeneration, embedded content timestamp 7 months stale; "recommended" blocklist name is wrong

Feodo Tracker's blocklist page (`https://feodotracker.abuse.ch/blocklist/`)
carries a site-wide banner: **"Empty datasets | Our Feodo Tracker datasets
are currently empty."** The plain IP blocklist is not literally empty but
is thin: `GET https://feodotracker.abuse.ch/downloads/ipblocklist.csv` →
`200`, `text/csv`, `Content-Length: 940`, `Cache-Control: max-age=300`,
HTTP `Last-Modified: Tue, 30 Jun 2026`. The CSV body itself carries its own
`# Last updated: 2026-03-04 14:28:39 UTC` comment line and exactly 5 data
rows (`# END 5 entries`) — both the HTTP header and the file's own
timestamp are stale relative to probe time (2026-10-05), and **they
disagree with each other by nearly 4 months** (Jun 30 HTTP header vs.
Mar 4 embedded line), despite the page's own prose claiming "The Botnet C2
IP Blocklist gets generated every 5 minutes."

The page documents a "Recommended IP blocklist" (plain-text/JSON) as the
one to use for low false positives, but no file at the guessed path
`ipblocklist_recommended.csv` exists: `GET
.../downloads/ipblocklist_recommended.csv` → `404`, `text/html`,
268 bytes. `ipblocklist_aggressive.csv` does exist (`200`, `text/csv`,
`Content-Length: 623072`, same stale embedded date `2026-03-04`), is 663×
larger than the plain list, and both files are generated by the same
pipeline — the size gap plus the identical stale timestamp indicates
no new C2 IP has been added to EITHER list since March despite the stated
5-minute cadence.

Reproduce:
```
curl -sI https://feodotracker.abuse.ch/downloads/ipblocklist.csv
# → 200, Last-Modified: Tue, 30 Jun 2026, Content-Length: 940
curl -s https://feodotracker.abuse.ch/downloads/ipblocklist.csv | head -3
# → "# Last updated: 2026-03-04 14:28:39 UTC"  (embedded, disagrees with HTTP header)
curl -sI https://feodotracker.abuse.ch/downloads/ipblocklist_recommended.csv
# → 404, text/html, 268 bytes (name does not exist; use *_aggressive instead)
```

How observed: 2026-10-05T11:03:59Z–11:04:28Z, direct HTTPS GET/HEAD (curl,
default UA), no credential held or sent.
