Server srv4.cloud.batacek.eu je připravený a máš k němu root přístup.
Než začneš: zadání se od chatu, ve kterém jsi vybíral konfiguraci serveru, změnilo. Upravil jsem popis prostředí, termíny i způsob, jakým se k serveru připojuješ — pokud si z minula pamatuješ něco jiného, platí to, co je v zadání projektu teď. Přečti si ho prosím znovu celé, ne jen zběžně. Pak nasaď honeypot podle zadání. Máš na to tento jeden chat — od jeho konce se na server podívám až při první kontrole a do té doby na něj nikdo nesáhne.

Prostředí je zmapované. Shrnu si klíčová zjištění, protože určují celý návrh:
- Debian 13, 3 vCPU, 7,8 GB RAM, 375 GB volného místa, bez swapu
wg0(10.10.0.3 ↔ 10.10.0.1) a runner na 26411 běží,wg-quick@wg0+hedgehog-runnerjsou enabledrsyslogposílá*.*na10.10.0.1:514— cokoli napíšu do syslogu, dostaneš průběžně- skutečný
sshdposlouchá na 0.0.0.0:22 a ty se přes něj hlásíš z 10.10.0.1 → port 22 musím honeypotu předat tak, aby tvůj přístup zůstal netknutý - na serveru není žádný lokální firewall (iptables ACCEPT, nftables nenainstalované)
Instaluji základ.

|
[ sitovy firewall Contabo — spravuje Tomas, ja ho nevidim ]
|
eth0 169.58.205.231
|
nftables prerouting (REDIRECT, jen provoz z eth0):
22 -> 42222 cowrie ssh
23, 2323 -> 42223 cowrie telnet
webove porty -> 42280 hpweb (HTTP)
443, 8443, .. -> 42443 hpweb (HTTPS)
vse ostatni -> 42000 hptcp catch-all
|
honeypot sluzby (neprivilegovane, systemd, Restart=always)
Puvodni cilovy port se cte pres `SO_ORIGINAL_DST`, takze catch-all vi, na jaky
port utocnik doopravdy miril, a podle toho vybere emulaci protokolu.
## Sluzby
| sluzba | co dela | uzivatel |
|---|---|---|
| `cowrie` | SSH + Telnet honeypot, falesny shell, TTY zaznamy relaci | cowrie |
| `hpweb` | HTTP/HTTPS, vlastni kod, loguje cela tela pozadavku | hpsvc |
| `hptcp` | catch-all pro vsechny ostatni porty, emulace ~15 protokolu | hpsvc |
| `hppcap` | tcpdump, plny zaznam paketu, hodinova rotace + gzip | root/hpsvc |
| `hp-watchdog.timer` | kontrola kazdych 5 minut, hlasi do syslogu | root |
## Kde jsou data
/var/log/honeypot/hpweb.jsonl HTTP/HTTPS udalosti
/var/log/honeypot/hptcp.jsonl ostatni protokoly
/var/log/honeypot/bodies/ payloady podle sha256 (dedup)
/var/log/honeypot/pcap/ pcap, hodinove, gzip
/var/log/honeypot/watchdog.jsonl zaznam kontrol
/opt/cowrie/cowrie/var/log/cowrie/cowrie.json SSH/Telnet udalosti
/opt/cowrie/cowrie/var/lib/cowrie/tty/ prehratelne relace
Prehrani relace: `cd /opt/cowrie/cowrie && ./cowrie-env/bin/playlog var/lib/cowrie/tty/<soubor>`
## Casove znacky — POZOR
* JSON pole `ts` / `timestamp` = **UTC** ve vsech zdrojich.
* Cowrie formatuje cas lokalne, ale znaci ho "Z". Proto ma sluzba `TZ=UTC`
(v `/etc/systemd/system/cowrie.service`) — tim je znacka pravdiva.
**Kdyby nekdo tuto promennou odstranil, znacky budou o 2 h posunute.**
Nezavisla kontrola: pole `epoch` v cowrie.json je vzdy spravne.
* Obalka syslogu je naopak v lokalnim case (Europe/Berlin, +02:00), protoze
systemova zona je Tomasova a nemenil jsem ji.
## Syslog
`/etc/rsyslog.d/92-honeypot.conf` cte tri JSONL soubory pres `imfile` a posila
je jako facility `local1`, tagy `hp-web:`, `hp-tcp:`, `hp-cowrie:`.
Tomasuv forward `*.* @@10.10.0.1:514` (soubor 90-forward.conf) je jeho a nesahat.
Radek JSON je tvrde omezen na 7000 B, aby se vesel do syslog zpravy (limit 8 kB);
useknuti se znaci polem `line_truncated`.
## Co se NESMI
1. Zastavit/menit `hedgehog-runner`, port 26411, `wg0`, `/etc/wireguard/`.
2. Otevrit 26411 do internetu.
3. Cokoli aktivne posilat proti cizim systemum. Proto ma nftables v output
retezci tvrdy zakaz odchozich spojeni pro uzivatele `cowrie` a `hpsvc`.
4. Mazat nebo prepisovat nasbirana data. Logy se nerotuji zamerne.
5. Zasahovat do `90-forward.conf` a do pristupu SSH z 10.10.0.1.
## Kdyz se neco pokazi
* sluzba spadla -> `systemctl reset-failed X; systemctl restart X` (hlidac to dela sam)
* chybi pravidla -> `nft -f /etc/nftables.conf` (hlidac to dela sam)
* dochazi disk -> hlidac nad 85 % zastavi `hppcap`; data se nikdy nemazou
* honeypot nesbira nic -> zkontroluj `nft list chain inet hpnat prerouting`;

# Denik zasahu na serveru
Kazda relace sem pripise, co udelala a proc. Nejnovejsi nahoru.
## 2026-08-21 (patek) — nasazeni
Postaveno: cowrie (SSH 22 + telnet 23), vlastni hpweb (HTTP/HTTPS), vlastni
hptcp (catch-all pro vsechny ostatni porty), tcpdump, hlidac, nftables.
Rozhodnuti a proc:
* **Vlastni kod na web a catch-all misto hotoveho reseni.** Chtel jsem plnou
kontrolu nad tim, co se loguje (cela tela pozadavku, presne casy, puvodni
cilovy port) a nulove zavislosti, ktere by se behem mesice mohly rozbit.
* **Cowrie na SSH/telnet** — vlastni psat nemelo smysl, emulovany shell a TTY
zaznamy jsou prilis dobre. Nainstalovano z gitu do venv.
* **Port 22 se nesahal v konfiguraci sshd.** Skutecny sshd dal posloucha na
0.0.0.0:22, ale nftables presmeruje provoz z eth0 na cowrie a navic ma
pojistku `iifname eth0 tcp dport 22 drop`. Tomasuv pristup z 10.10.0.1 pres
tunel tim zustal netknuty. Zvazoval jsem prebindovat sshd jen na 10.10.0.3 —
zavrhl jsem to, protoze to zasahuje do jeho pristupove cesty.
* **Odchozi spojeni honeypotu zablokovana na urovni uzivatele** (skuid cowrie,
hpsvc). Duvod: cowrie by jinak na pokyn utocnika stahoval soubory z cizich
serveru. Cena: neziskame vzorky malwaru. Zustava nam ale cela URL i prikaz.
* **Zadny UDP.** Odpovidajici UDP sluzba je zneuzitelna k zesilenym DDoS utokum
proti tretim stranam. Radeji prijdu o data o SIP/DNS skenech.
* **Falesna otevrena proxy** (CONNECT i absolutni URI) — odpovime "200 OK", ale
NIC nepreposilame, jen logujeme, co by nam protistrana poslala.
* **Logy se nerotuji.** Rotace by znamenala mazani. Misto toho hlidac hlida disk.
Co se pri nasazeni nepovedlo (zaznamenano zamerne):
* Runner spousti prikazy pres `/bin/sh` (dash), ne bash — prvni `mkdir` s
slozenymi zavorkami vytvoril adresar jmenem `{bin,etc,var}`. Uklizeno.
* Testovaci import mych modulu pod rootem zalozil `.jsonl` soubory s vlastnikem
root, takze sluzby pod `hpsvc` do nich nemohly psat a padaly v restart smycce.
Pricina: `EventLog` se vytvari uz pri importu modulu. Opraveno chownem.
* `pkill -f 'twistd.*cowrie'` zabil sam sebe (vzorec odpovidal i prikazove radce
spousteciho shellu) a prerusil celou davku. Cowrie unit se pak musel zalozit znovu.
* Cowrie hlasi lokalni cas s priponou "Z". Vyreseno `TZ=UTC` ve service.
* Cowrie neumi soucasne `tcp:` a `tcp6:` endpoint na stejnem portu (Address

Hotovo. Honeypot běží a je ověřený včetně dvou restartů.
Co na serveru běží
| služba | co dělá |
|---|---|
| cowrie | SSH + Telnet, emulovaný shell, plné TTY záznamy relací (dají se přehrát) |
| hpweb | vlastní HTTP/HTTPS server — loguje celá těla požadavků, SNI, TLS verzi |
| hptcp | vlastní catch-all pro všechny ostatní porty, ~15 emulovaných protokolů |
| hppcap | tcpdump, plný obsah paketů, hodinová rotace + gzip |
| hp-watchdog | kontrola každých 5 minut, hlásí problémy do syslogu |
Provoz z internetu přesměrovává nftables podle portu; catch-all si přes SO_ORIGINAL_DST zjistí, kam útočník doopravdy mířil, a podle toho zvolí emulaci. Ověřeno: PostgreSQL vydá jméno, databázi i heslo v plaintextu, RDP mstshash= cookie, SMTP dekóduje base64 AUTH, Redis zaznamená CONFIG SET.
Do syslogu (facility local1, tagy hp-cowrie:, hp-web:, hp-tcp:) teče všechno průběžně přes imfile. Primární úložiště jsou ale JSONL soubory na disku — když rsyslog vypadne, nepřijdeš o nic.
Časové značky: všechna pole ts/timestamp v JSON jsou UTC. Obálka syslogu zůstává v CEST, systémovou zónu jsem neměnil.
SÍŤOVÝ FIREWALL
1-26410/tcp — honeypot, celý rozsah (catch-all obslouží každý port)
26412-65535/tcp — honeypot, celý rozsah
26411/tcp — NEOTVÍRAT, řídicí runner
51820/udp — WireGuard, už otevřeno, beze změny
UDP jinak — nechat zavřené (záměr, viz níže)Prosím o celý rozsah místo výběru portů: catch-all zvládne cokoli a získáme tím skutečné rozložení toho, kam boti míří, ne jen to, co jsem předem tipl. Kdyby ti to bylo moc, minimum s největší výtěžností je 22, 23, 80, 443, 445, 3306, 3389, 5432, 6379, 8080, 8443/tcp.
Rozhodnutí, která něco stála
- Odchozí spojení honeypotu jsou tvrdě zablokovaná (nftables podle UID). Cowrie by jinak na pokyn útočníka stahoval soubory z cizích serverů. Cena: nebudeme mít vzorky malwaru — zůstane nám celá URL i příkaz. Přišlo mi to bezpečnější než mít server, který na cizí pokyn někam sahá.
- Žádné UDP. Odpovídající UDP služba je zneužitelná k zesíleným DDoS útokům proti třetím stranám.
- Falešná otevřená proxy — na
CONNECTodpovíme „200 OK", ale nic nepřeposíláme, jen logujeme. - Logy se nerotují. Rotace = mazání. Nad 85 % disku hlídač zastaví jen pcap.
Co se nepovedlo
- Runner spouští příkazy v
dash, ne bash — prvnímkdirse složenými závorkami vyrobil adresář jménem{bin,etc,var}. - Můj test-import modulu pod rootem založil logovací soubory s vlastníkem root; služby pod
hpsvcdo nich pak nemohly psát a padaly ve smyčce. pkill -f 'twistd.*cowrie'zabil sám sebe, protože vzorec seděl i na spouštěcí shell, a přerušil celou dávku.- Cowrie píše lokální čas s příponou
Z. VyřešenoTZ=UTC.
Dvě věci pro tebe
1. Našel jsem závadu v prostředí. rsyslog startoval 1,6 s před wg-quick@wg0, takže se po každém restartu pokoušel spojit s kolektorem přes veřejné rozhraní a asi 2 minuty visel v SYN-SENT — tvůj živý odběr logů byl tu dobu mimo. Přidal jsem drop-in /etc/systemd/system/rsyslog.service.d/10-after-wireguard.conf s jediným řádkem After=wg-quick@wg0.service. Tvoje konfigurace zůstala nedotčená, ale chci, abys o té změně věděl. Ověřeno druhým restartem: teď je spojení navázané okamžitě.
Zároveň: tvůj 90-forward.conf nemá nastavenou frontu akce. Až honeypot pojede naostro, poteče tam řádově víc zpráv — kdyby byl kolektor delší dobu nedostupný, může to rsyslog zdržovat. Nesahal jsem na to, je to tvůj soubor.
2. Prosba o rozhodnutí ohledně sshd. Skutečný sshd má PermitRootLogin yes, PasswordAuthentication yes a root má nastavené heslo. Port 22 z internetu odchytávám na cowrie a mám i záložní pravidlo iifname eth0 tcp dport 22 drop, takže se k pravému sshd nikdo nedostane. Ale kdyby po restartu z nějakého důvodu nenaběhla nftables pravidla, byl by pravý sshd s heslem vystavený internetu. Do tvé přístupové cesty jsem záměrně nesahal — dej vědět, jestli mám sshd přebindovat jen na 10.10.0.3 a 127.0.0.1, nebo to necháš být.
Na serveru je /opt/honeypot/RUNBOOK.md a JOURNAL.md — příští kontrola začne příkazem hp-status 72.
Síťový firewall je nastaven.
Proveď kontrolu serveru srv4.cloud.batacek.eu.
Co konkrétně zkontroluješ a jestli na základě toho něco změníš, je tvoje rozhodnutí.
Tři procedurální věci k tomu:
- Tohle je poslední zpráva v tomhle chatu. Jediné, co ode mě ještě může přijít, je „continue", pokud tě zastaví limit.
- Další kontroly proběhnou ve stejném projektu, ale každá ve vlastním novém chatu.
- Na otázky ti neodpovídám — ani na ty, které jsi už položil. Odpověď je vždycky buď v zadání projektu, nebo je to rozhodnutí, které je na tobě.

Firewall je otevřený — od téhle chvíle je server pod skutečnou palbou. Beru to jako 1. kontrolu a začnu tím, čím má začínat každá: přehledem stavu.
Poznámku o tom, že už neodpovídáš na otázky, beru. Rozhodnutí o sshd si tedy udělám sám, až uvidím data.

## 2026-08-22 (sobota) — 1. kontrola
Sitovy firewall otevren, honeypot pod plnou palbou. Za prvnich 18 h:
245 000 udalosti, 2 629 unikatnich IP, 3 237 uspesnych prihlaseni do cowrie,
11 746 zachycenych prikazu. Zadna chyba v mem kodu (0x handler_error).
Nalezene problemy a co jsem s nimi udelal:
1. **ZTRATA DAT: 7 387 z 66 000 spojeni (11 %) odmitnuto** na catch-all kvuli
limitu soubeznych spojeni (MAX_CONN=600). Pricina: skenery otviraji stovky
spojeni naraz a `emu_generic` drzel kazde az 36 s.
Opraveno: limit 600 -> 3000, `sem.acquire(timeout=2)` misto okamziteho
odmitnuti (kratky naval pocka ve fronte jadra), zkracene timeouty
(12+3x8 s -> 10+2x5 s), TasksMax 3500, MemoryMax 1500M, NOFILE 65536.
Odmitnute spojeni se nove zaznamena jako `conn_rejected` — driv bylo
uplne neviditelne, jen v citaci.
2. **pcap se nekomprimoval.** AppArmor profil `tcpdump` zakazuje spustenemu
gzipu zapis do /var/log/honeypot/pcap (DENIED v kern.log).
Opraveno obchazkou mimo profil: z tcpdumpu odstraneno `-z gzip`, komprimuje
samostatny `hp-compress.timer` pod rootem (jen soubory starsi 75 min, aby
nesahl na prave otevreny). 121 MB -> 52 MB.
3. **Chybne znacky protokolu.** `emu_binary()` vracela funkci jmenem `f`,
takze conn_close u SMB/RDP/MSSQL/Mongo hlasil `proto:"f"`. Opraveno.
4. **PostgreSQL emulator** oznacoval jako "heslo" i data, ktera nebyla
PasswordMessage (napr. `port=15432`). Nove se to loguje jako prikaz.
5. **`::ffff:` prefix u cowrie** — neni chyba, ale past pri analyze.
Zdokumentovano v RUNBOOK, hp-status uz adresy normalizuje.
Hlidac zprisnen: bezi kazde 2 minuty (bylo 5), po startu za 45 s (bylo 3 min),
a nove overuje konkretni kriticka pravidla firewallu (ridici kanal, pojistka
sshd, obe presmerovani), ne jen existenci tabulek. Hlasi i `conn_rejected`.
**ROZHODNUTI O sshd — uzavreno, znovu neotvirat.** Nechavam sshd nedotcene.
Duvody: za 18 h tvrdeho provozu doslo k *nula* pokusum o prihlaseni na skutecny
sshd (`grep -c 'Failed password' /var/log/auth.log` = 0), presmerovani i pojistka
prokazatelne funguji, hlidac je kontroluje kazde 2 minuty. Zbytkove riziko
(vypadek celeho rulesetu) nevyvazi zasah do pristupove cesty, kterou si Tomas
vyhradil (bod 8.7). Tomasovo prihlaseni z 10.10.0.1 overeno jako funkcni.
Odhad objemu dat na cely beh: ~8 GB pred kompresi, po kompresi vyrazne min.
Disk 374 GB volnych — misto neni riziko.

hpweb je v pořádku — jen na standardních portech 80/443 chodí málo provozu, což potvrzuje zjištění, že většina webových útoků míří na nestandardní porty. Zbývá jedna preventivní věc: za 26 dní budou logy mít gigabajty a hp-status by je nestihl přečíst.

Kontrola hotová. Honeypot funguje, ale našel jsem při ní pět věcí, které jsem musel opravit — a jednu z nich považuji za nejdůležitější zjištění celého dne.
Co honeypot za 18 hodin nasbíral
245 000 událostí, 2 629 unikátních IP, 3 237 úspěšných přihlášení do Cowrie a 11 746 zachycených příkazů. Nejčastější sekvence po přihlášení je system → sh → shell → enable → linuxshell, což je učebnicový Mirai/Gafgyt. Zachytil jsem i URL, ze kterých se boti pokoušeli stáhnout binárky (http://31.77.227.121/bins/pmips, ftp://185.93.89.72/ftpget) — odchozí blokace 153× zafungovala, takže se nic nestáhlo, ale adresy máme. Nejagresivnější je celý blok 85.217.149.0/24.
Ztráta dat, kterou jsem zastavil
7 387 z 66 000 spojení (11 %) bylo odmítnuto kvůli limitu souběžnosti. Skenery otevírají stovky spojení naráz a můj catch-all držel každé neznámé spojení až 36 sekund, takže na nárazy nestačil. Zvýšil jsem limit z 600 na 3 000, zkrátil čekání a hlavně nahradil okamžité odmítnutí krátkým čekáním ve frontě jádra. Odmítnuté spojení se nově aspoň zaznamená jako conn_rejected — dosud bylo úplně neviditelné.
To je přesně ten typ chyby, který by bez kontroly tiše ukrajoval data celý měsíc.
Další opravy
- pcap se nekomprimoval — AppArmor profil
tcpdumpzakazuje spuštěnémugzipzápis do adresáře. Kompresi jsem přesunul mimo profil do samostatného časovače. 121 MB → 52 MB. - Špatné značky protokolů — SMB, RDP, MSSQL a Mongo se v
conn_closehlásily jakoproto:"f"(chyba v mém generátoru funkcí). - PostgreSQL emulátor označoval jako „heslo" i data, která hesly nebyla.
hp-statusby v závěru běhu přestal stačit — četl logy celé od začátku, při očekávaných 2,5 GB by kontrola trvala minuty. Teď čte od konce, 2,5 s.
Hlídač jsem zpřísnil: běží každé 2 minuty místo 5, po startu za 45 s, a nově ověřuje konkrétní kritická pravidla firewallu (řídicí kanál, pojistku sshd, obě přesměrování), ne jen existenci tabulek. Hlásí i odmítnutá spojení.
Past pro pozdější analýzu
Cowrie loguje IPv4 adresy jako ::ffff:1.2.3.4, moje služby jako 1.2.3.4. Při naivním sčítání se stejný útočník objeví dvakrát — normalizuj src_ip.removeprefix("::ffff:"). A druhá věc: většina webových útoků nechodí na 80/443, ale na porty jako 3000, 5173, 8880 nebo 10001, takže jejich http_request události končí v hptcp.jsonl, ne v hpweb.jsonl. Za 18 h to bylo 13 696 požadavků v hptcp proti 3 562 událostem v hpweb. Obojí je zapsané v RUNBOOK.md.
Rozhodnutí o sshd — uzavřeno
Ptal jsem se tě na to minule; beru, že odpověď je na mně. Nechávám sshd nedotčené. Za 18 hodin tvrdého provozu proběhlo nula pokusů o přihlášení na skutečný sshd — přesměrování i záložní pravidlo prokazatelně fungují a hlídač je teď kontroluje každé 2 minuty. Zbytkové riziko nevyváží zásah do přístupové cesty, kterou sis v bodě 8.7 vyhradil. Tvoje přihlášení z tunelu funguje (11 úspěšných). Rozhodnutí i s odůvodněním jsem zapsal do deníku, aby ho příští kontrola zbytečně neotvírala znovu.
SÍŤOVÝ FIREWALL
