## Internet protokol za pristup porukama
|
|
|
|
**Internet protokol za pristup porukama (IMAP)** je dizajniran sa ciljem omogućavanja korisnicima da **pristupe svojim email porukama sa bilo kog mesta**, uglavnom putem internet konekcije. U osnovi, email poruke se **čuvaju na serveru** umesto da se preuzimaju i čuvaju na ličnom uređaju pojedinca. To znači da kada se pristupa ili čita email, to se radi **direktno sa servera**. Ova sposobnost omogućava praktičnost provere emailova sa **više uređaja**, osiguravajući da nijedna poruka ne bude propuštena bez obzira na korišćeni uređaj.
|
|
|
|
Podrazumevano, IMAP protokol radi na dva porta:
|
|
|
|
* **Port 143** - ovo je podrazumevani IMAP nešifrovani port
|
|
* **Port 993** - ovo je port koji treba koristiti ako želite da se povežete koristeći IMAP sigurno
|
|
```
|
|
PORT STATE SERVICE REASON
|
|
143/tcp open imap syn-ack
|
|
```
|
|
## Preuzimanje banera
|
|
```bash
|
|
nc -nv <IP> 143
|
|
openssl s_client -connect <IP>:993 -quiet
|
|
```
|
|
### NTLM Auth - Otkrivanje informacija
|
|
|
|
Ako server podržava NTLM autentikaciju (Windows), možete dobiti osetljive informacije (verzije):
|
|
```
|
|
root@kali: telnet example.com 143
|
|
* OK The Microsoft Exchange IMAP4 service is ready.
|
|
>> a1 AUTHENTICATE NTLM
|
|
+
|
|
>> TlRMTVNTUAABAAAAB4IIAAAAAAAAAAAAAAAAAAAAAAA=
|
|
+ TlRMTVNTUAACAAAACgAKADgAAAAFgooCBqqVKFrKPCMAAAAAAAAAAEgASABCAAAABgOAJQAAAA9JAEkAUwAwADEAAgAKAEkASQBTADAAMQABAAoASQBJAFMAMAAxAAQACgBJAEkAUwAwADEAAwAKAEkASQBTADAAMQAHAAgAHwMI0VPy1QEAAAAA
|
|
```
|
|
Ili **automatizujte** ovo sa **nmap** dodatkom `imap-ntlm-info.nse`

|
### CURL
|
|
|
|
Osnovna navigacija je moguća pomoću [CURL](https://ec.haxx.se/usingcurl/usingcurl-reademail#imap), ali dokumentacija je siromašna detaljima, pa se preporučuje provera [izvora](https://github.com/curl/curl/blob/master/lib/imap.c) za precizne detalje.
|
|
|
|
1. Lista sandučića (imap komanda `LIST "" "*"`)
|
|
```bash
|
|
curl -k 'imaps://1.2.3.4/' --user user:pass
|
|
```
|
|
2. Prikazivanje poruka u sandučetu (imap komanda `SELECT INBOX` a zatim `SEARCH ALL`)
|
|
```bash
|
|
curl -k 'imaps://1.2.3.4/INBOX?ALL' --user user:pass
|
|
```
|
|
Rezultat ove pretrage je lista indeksa poruka.
|
|
|
|
Takođe je moguće koristiti složenije pretrage. npr. pretraga za skicama sa lozinkom u telu poruke:
|
|
```bash
|
|
curl -k 'imaps://1.2.3.4/Drafts?TEXT password' --user user:pass
|
|
```
|
|
Ako želite da preuzmete poruku, koristite IMAP komandu `SELECT Drafts` a zatim `FETCH 1 BODY[]`.
|
|
```bash
|
|
curl -k 'imaps://1.2.3.4/Drafts;MAILINDEX=1' --user user:pass
|
|
```
|
|
Mail indeks će biti isti indeks koji je vraćen iz operacije pretrage.
|
|
|
|
Takođe je moguće koristiti `UID` (jedinstveni identifikator) za pristup porukama, međutim to je manje pogodno jer komanda pretrage mora biti ručno formatirana. Npr.
|
|
```bash
|
|
curl -k 'imaps://1.2.3.4/INBOX' -X 'UID SEARCH ALL' --user user:pass
|
|
curl -k 'imaps://1.2.3.4/INBOX;UID=1' --user user:pass
|
|
```
|
|
Takođe, moguće je preuzeti samo delove poruke, npr. predmet i pošiljaoca prvih 5 poruka (opcija `-v` je potrebna da bi se videli predmet i pošiljalac):
|
|
```bash
|
|
$ curl -k 'imaps://1.2.3.4/INBOX' -X 'FETCH 1:5 BODY[HEADER.FIELDS (SUBJECT FROM)]' --user user:pass -v 2>&1 | grep '^<'
|
|
```
|
|
Iako je verovatno čistije jednostavno napisati mali for petlju:
|
|
```bash
|
|
for m in {1..5}; do
|
|
echo $m
|
|
curl "imap://1.2.3.4/INBOX;MAILINDEX=$m;SECTION=HEADER.FIELDS%20(SUBJECT%20FROM)" --user user:pass
|
|
done
|
|
```
|

The Internet Message Access Protocol (IMAP) is designed for the purpose of enabling users to access their email messages from any location, primarily through an Internet connection. In essence, emails are retained on a server rather than being downloaded and stored on an individual's personal device. This means that when an email is accessed or read, it is done directly from the server. This capability allows for the convenience of checking emails from multiple devices, ensuring that no messages are missed regardless of the device used.
