## Taarifa Msingi
|
|
|
|
**OPC UA**, ikimaanisha **Open Platform Communications Unified Access**, ni itifaki muhimu ya chanzo wazi inayotumiwa katika viwanda mbalimbali kama vile Uzalishaji, Nishati, Anga, na Ulinzi kwa kubadilishana data na kudhibiti vifaa. Inawezesha vifaa kutoka wauzaji tofauti kuwasiliana, hasa na PLCs.
|
|
|
|
Usanidi wake unaruhusu hatua kali za usalama, lakini mara nyingi, kwa utangamano na vifaa vya zamani, hatua hizi hupunguzwa, na hivyo kuweka mifumo katika hatari. Aidha, kupata huduma za OPC UA inaweza kuwa ngumu kwani skana za mtandao huenda zisizigundue ikiwa ziko kwenye bandari zisizostahili.
|
|
|
|
**Bandari ya chaguo-msingi:** 4840
|
|
```text
|
|
PORT STATE SERVICE REASON
|
|
4840/tcp open unknown syn-ack
|
|
```
|
|
## Pentesting OPC UA
|
|
|
|
Ili kugundua masuala ya usalama katika seva za OPC UA, skani kwa kutumia [OpalOPC](https://opalopc.com/).
|
|
```bash
|
|
opalopc -vv opc.tcp://$target_ip_or_hostname:$target_port
|
|
```
|
|
### Kudukua udhaifu
|
|
|
|
Ikiwa udhaifu wa kuthibitisha utambulisho unapatikana, unaweza kusanidi [mteja wa OPC UA](https://www.prosysopc.com/products/opc-ua-browser/) kulingana na hilo na kuona unaweza kupata nini. Hii inaweza kuruhusu kusoma tu thamani za mchakato au hata kufanya kazi na vifaa vya viwandani vya kazi nzito.
|
|
|
|
Ili kupata wazo la kifaa unachoweza kupata, soma thamani za nodi ya "ServerStatus" katika nafasi ya anwani na tafuta kwenye Google kwa mwongozo wa matumizi.
