## Changes things (9)

Creates or changes something that can be changed back. Claude Code: ask.

### `asn_enrich_tool`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Full honeypot profile for an ASN (autonomous system / hosting provider). Use for:
'tell me about AS202425', 'what is Vultr doing in my honeypots?', 'attacks from this
hosting provider', 'attribute this IP to its network'. asn format: 'AS12345'.
Returns: total events, unique IPs, top targeted ports, top source countries, top user
agents, org name. since/until are ISO-8601 UTC strings.
```

### `attack_timeline_tool`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Attack volume over time, bucketed by hour or day. Use for: 'show attack trends this
week', 'was there a spike on port 22?', 'how has SSH scanning changed?', 'attack volume
from China over 30 days'. bucket: 'hour' or 'day'. Optional filters: filter_protocol
('tls'/'''), filter_country (2-letter code), filter_dest_port. since/until ISO-8601 UTC.
```

### `feint_credentials_tool`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Plaintext logins captured by the interactive (Feint) sensors: username, password, the
service they were tried on, the outcome and the source address, newest first, plus the
pairs tried most and a per-service breakdown. Use when a user asks: 'what passwords are
attackers trying on SSH?', 'which credentials did this IP try?', 'what logins hit the
MySQL honeypots this week?'. service is a Feint service name such as ssh-password,
telnet-login, mysql-login, rdp-credssp or smb-ntlmssp (empty for all); source is an
address or CIDR (empty for all); window is 24h, 7d or 30d. Feint data is kept apart
from the Spip surfaces: it feeds no verdict or feed and ioc_lookup does not include it.
```

### `feint_files_tool`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Files clients handed to the interactive (Feint) sensors: uploads, mail attachments,
published messages and other artifacts, by SHA-256, with name, size, MIME type, the
sessions that carried them and the VirusTotal verdict when the collector has one. Use
when a user asks: 'have you seen this hash?', 'what files did this IP upload?', 'which
malware samples reached the honeypots this month?'. sha256 is one hash (empty for every
file in the window); source is an address or CIDR; window is 24h, 7d or 30d.
```

### `feint_sessions_tool`

- Nothing in its name or description says what it does, so it is counted as a write.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Sessions one address or range held with the interactive (Feint) sensors: when, which
port and protocol, the persona answered as, the verdict (scan, credential, exploit),
labels, turns, bytes, duration, CVE ids evidenced by the payload, path-only CVE
candidates and the download URLs the client named, newest first, with verdict, persona
and port breakdowns. Use after ioc_lookup when a user asks what an address did inside a
session: 'what did this IP do on the honeypots?', 'did this range get past a login?',
'which exploits did this IP try?'. source is required: an address or a CIDR; window is
24h, 7d or 30d.
```

### `fingerprint_population_tool`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
The population behind a single client fingerprint: how many source IPs carry it,
across how many networks (ASNs) and countries, the ports they hit, the top networks
and a sample of the IPs, plus a read on its shape: concentrated (many IPs on few
networks), dispersed (many networks but one short burst on one or two ports, which
is a coordinated operation spread thinly on purpose), spread (a common client)
or mixed. Concentrated and dispersed are both coordinated operations.
Use when a user asks: 'is this JA4 one botnet or a common tool?', 'how many networks
use this HASSH?', 'how specific / concentrated is this fingerprint?'. fp_type: 'ja4'
(TLS), 'akin' (HTTP request shape) or 'hassh' (SSH). Covers the full retained window
(no date range).
```

### `fingerprint_similar_tool`

- The description's first verb is "request": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Request shapes within a few headers of an Akin HTTP fingerprint, with what
those clients ask for and call themselves, plus the family the token belongs
to. Use when one odd request shape turns up in your own web, WAF or proxy logs
and you want to know whether it is a known tool with variants: 'what is close
to this fingerprint', 'is this the same scanner with one header added', 'what
does this client family go after'. max_distance is in headers, 1 to 4. Only
Akin can answer this; a hashed fingerprint changes completely when a header is
added.
```

### `top_attackers_tool`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Ranked leaderboard of attack sources. Use for: 'who is attacking the most?', 'top
attacking countries', 'most targeted ports', 'most common user agents', 'top ASNs by
attack volume', 'top IPs from China', 'top attackers hitting port 22'.
'by' controls grouping: ip, asn, country, port, user_agent, ja4, url_path, domain, cve.
by='cve' answers 'what CVEs are being mass-scanned right now' and returns
value (the CVE id), title, severity, actively_exploited (on the CISA KEV catalogue),
kev_date_added and counts; drill into any of them with cve_lookup. by='cve' does not accept the country/dest_port/asn filters.
Optional filters: country (2-letter ISO, e.g. 'CN'), dest_port, asn (e.g. 'AS12345').
Adding a filter is required for large time ranges to stay within memory limits.
since/until are ISO-8601 UTC strings.
```

### `udp_activity_tool`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
UDP datagrams sent to the sensors: DNS questions, QUIC client fingerprints and other
UDP probes, with the ports, networks and countries involved. Use when a user asks:
'who is sending DNS ANY queries?', 'is anyone querying version.bind?', 'have you seen
this QUIC JA4?', 'which UDP ports are being probed?', 'what hits 5060/udp?'. query uses
the /udp search grammar, for example 'qtype:ANY', 'qname:version.bind', 'proto:quic',
'port:5060 country:CN', 'ja4:q13d0310h3_55b375c5d22e_cd85d2d88918' or
'quic:3f1a9c2b7d40'; leave it empty for the overview. window is 24h, 7d or 30d.
A UDP source address can be forged: treat every address here as claimed, never as
evidence against it.
```

## Only reads (5)

Looks things up and changes nothing. Claude Code: allow.

### `cve_lookup_tool`

- The name "cve_lookup_tool" says "lookup": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Who is probing a specific CVE. Use whenever the user names a CVE: 'is CVE-2024-4577
being exploited in the wild?', 'who is scanning for this CVE?', 'show me actors probing
CVE-2023-1389'. Returns title, severity, KEV status (actively_exploited, and `kev`: the
CISA catalogue entry with date_added, or null), event and unique-IP counts
over both sensor types (first_contact_events and interactive_requests split them; an
address both saw counts once), the top probing IPs with country/ASN and `scanner`
(name and kind when the address is a recognised research, commercial or vendor
scanner, else null), top ASNs and countries, exploiter fingerprints, sample request paths, a daily timeline, and
`interactive`: what the interactive sensors recorded of the probes. window: 24h, 7d,
30d or 90d on every plan; 180d, 365d or all (the whole archive) on plans with the full
history, which the daily timeline then spans.
`observed: false` with a note means we hold no detection pattern for that CVE, which is
NOT the same as nobody scanning it. Do not use payload_search for a CVE id: the id is
our tag for a pattern and never appears in the payload text.
```

### `fingerprint_search_tool`

- The name "fingerprint_search_tool" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search honeypot activity by TLS, HTTP, or SSH fingerprint. Use when a user asks:
'have you seen this JA4 fingerprint?', 'which IPs share this TLS fingerprint?', 'how
common is this HASSH?', 'find all scanners with this SSH client fingerprint'. fp_type:
'ja4' (TLS client), 'ja3' (legacy TLS client, MD5, still keyed by many TI feeds),
'akin' (HTTP request shape, e.g. b11cun030_00040014_54d07b6d), 'hassh' (SSH client).
since/until are ISO-8601 UTC strings.
```

### `ioc_lookup_tool`

- The name "ioc_lookup_tool" says "lookup": a word for reading.
- Findings: info long-description

Description, as the server wrote it:

```untrusted-server-text
Look up any IP address, CIDR network, set of networks, or domain in the honeypot
    dataset. Use this FIRST whenever the
    user asks: 'is this IP malicious?', 'is this a known scanner?', 'have you seen this IP?',
    'what does this IP do?', 'when was it last seen?', 'is this IP in your data?'. Returns:
    total_events (0 = never observed), first_seen, last_seen, country, ASN, the 50 most-hit
ports plus ports_targeted_count for the true total,
    top user agents, top URL paths, TLS/HTTP/SSH fingerprints. Covers both IPv4 and domains.
    Also returns our own judgement: `verdict` (human sentence) with `verdict_key` (stable
    machine value to alert on) and `verdict_why`; `scanner` (benign-scanner identity from our
    classification table, or null) so research traffic can be told apart from real attacks;
    and `cve_probes`, the CVE signatures this address was seen probing.

    WINDOW: `days` bounds the query to the last N days. For a single address
    leave it unset for every retained event, which is the right default for
    "have we ever seen this". A CIDR or a domain defaults to the last 90 days,
    because neither can use an index and unbounded they read the whole table;
    pass `days` explicitly to widen either back out. The website's /lookup
    defaults to 7 days for anonymous visitors, so the same address can read very
    differently on the two surfaces. Every response states which window it used
    in `window`; quote it alongside any count you report.

    RANGES: pass a CIDR ('103.66.28.0/22') for a whole-network aggregate, or several at once
    separated by commas, spaces or newlines ('103.66.28.0/22, 8.34.210.32/27') to answer
    'have any of this vendor's ranges touched us' in ONE call. Never expand a network into
    individual addresses and loop -- that is hundreds of calls for an answer this returns in
    one, and it will exhaust your quota. A range answer sets query_type to 'cidr' or
    'cidr_set', lists every range back in `ranges`, and gives `per_range` counts plus
    `top_source_ips`; total_events 0 with those fields present is a real observed absence.
```

### `payload_search_tool`

- The name "payload_search_tool" says "search": a word for reading.
- Findings: warn tool-shadowing

Description, as the server wrote it:

```untrusted-server-text
Literal substring search over captured request text: URL path, request body,
request headers and event summary. Use for: 'find attacks targeting /wp-admin',
'find requests with this user agent string', 'what payloads hit port 80 last week'.

It matches text that literally appeared in the request, and nothing else. These do
NOT work and will return an empty list:
  - a CVE id ('CVE-2024-4577'), which is our tag for a pattern, never payload text.
    Use cve_lookup instead. This tool rejects them rather than answering emptily.
  - a product or vendor name ('Cisco FMC', '7-Zip'), which appears in an advisory,
    not in the request. Search the endpoint it exposes instead, e.g. '/ccmadmin' or
    the vulnerable path.
  - a description of behaviour ('SQL injection attempts'). Search a marker that
    occurs in the traffic, e.g. 'UNION SELECT' or '../'.

An empty list is a real answer: it means no captured request in that window
contained the string. Widen since/until before concluding the activity does not
exist. Free to call; volume is metered like every other tool.
since/until are ISO-8601 UTC strings.
```

### `search_events_tool`

- The name "search_events_tool" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return individual raw honeypot events with all fields. Use when the user wants to see
actual records: 'show me events from this IP', 'what hit port 443 last week', 'events from
Russia yesterday'. Filters: source_ip, country (2-letter code), asn (e.g. 'AS12345'),
dest_port, protocol ('tls' or '' = the coarse TLS/raw-TCP signal),
app_protocol (nDPI L7 protocol label: 'bittorrent', 'ssh', 'rdp', 'mssql-tds', 'mining',
'rtsp', 'smbv1', ... — find everything speaking a protocol regardless of port),
http_method, request_header (substring of the masked
HTTP request headers), source_domain (reverse DNS name, substring), ja4/ja3
(exact TLS client fingerprint), akin (exact HTTP request fingerprint, e.g.
b11cun030_00040014_54d07b6d),
has_client_cert (true = only events where the client presented an mTLS cert),
ip_version (4 or 6 = only IPv4 or IPv6 sources).
since/until are ISO-8601 UTC strings. Each record includes: source_ip, country, asn,
dest_port, user_agent, url_path, http_request_headers, tls_client_ja4, tls_client_ja3,
tls_client_hello_hex (the raw TLS ClientHello, for verifying or recomputing
fingerprints), ssh_client_hassh, tls_client_cert_subject/issuer,
event_sequence, event_duration, source_bytes/dest_bytes/network_bytes, network_protocol,
application_protocol, timestamp.
```
