## Internetboodskaptoegangprotokol
|
|
|
|
Die **Internetboodskaptoegangprotokol (IMAP)** is ontwerp met die doel om gebruikers in staat te stel om **hul e-posboodskappe vanaf enige plek te benader**, hoofsaaklik deur 'n internetverbinding. In essensie word e-posse **op 'n bediener bewaar** eerder as om afgelaai en gestoor te word op 'n individu se persoonlike toestel. Dit beteken dat wanneer 'n e-pos geopen of gelees word, dit **direk vanaf die bediener** gedoen word. Hierdie vermoë maak dit moontlik om gerieflik e-posse vanaf **verskeie toestelle** te kontroleer, en verseker dat geen boodskappe gemis word nie, ongeag die gebruikte toestel.
|
|
|
|
Standaard werk die IMAP-protokol op twee poorte:
|
|
|
|
* **Poort 143** - dit is die verstek IMAP nie-geënkripteerde poort
|
|
* **Poort 993** - dit is die poort wat jy moet gebruik as jy wil koppel met IMAP op 'n veilige manier
|
|
```
|
|
PORT STATE SERVICE REASON
|
|
143/tcp open imap syn-ack
|
|
```
|
|
## Banier gryp
|
|
```bash
|
|
nc -nv <IP> 143
|
|
openssl s_client -connect <IP>:993 -quiet
|
|
```
|
|
### NTLM-verifisering - Inligtingsoffening
|
|
|
|
Indien die bediener NTLM-verifisering ondersteun (Windows) kan jy sensitiewe inligting (weergawes) verkry:
|
|
```
|
|
root@kali: telnet example.com 143
|
|
* OK The Microsoft Exchange IMAP4 service is ready.
|
|
>> a1 AUTHENTICATE NTLM

|
|
```
|
|
Of **outomatiseer** dit met **nmap** invoegtoepassing `imap-ntlm-info.nse`

### CURL
|
|
|
|
Basiese navigasie is moontlik met [CURL](https://ec.haxx.se/usingcurl/usingcurl-reademail#imap), maar die dokumentasie is lig op besonderhede, dus word dit aanbeveel om die [bron](https://github.com/curl/curl/blob/master/lib/imap.c) te kontroleer vir presiese besonderhede.
|
|
|
|
1. Lys van posbusse (imap-opdrag `LIST "" "*"`)
|
|
```bash
|
|
curl -k 'imaps://1.2.3.4/' --user user:pass
|
|
```
|
|
2. Lys van boodskappe in 'n posbus (imap-opdrag `SELECT INBOX` en dan `SEARCH ALL`)
|
|
```bash
|
|
curl -k 'imaps://1.2.3.4/INBOX?ALL' --user user:pass
|
|
```
|
|
Die resultaat van hierdie soektog is 'n lys van boodskapindekse.
|
|
|
|
Dit is ook moontlik om meer komplekse soekterme te verskaf. bv. soek na konsepte met wagwoord in e-pos liggaam:
|
|
```bash
|
|
curl -k 'imaps://1.2.3.4/Drafts?TEXT password' --user user:pass
|
|
```
|
|
'n Lekker oorsig van die soekterme moontlik is geleë [hier](https://www.atmail.com/blog/imap-commands/).
|
|
|
|
3. Aflaai van 'n boodskap (imap bevel `SELECT Konsepte` en dan `FETCH 1 BODY[]`)
|
|
```bash
|
|
curl -k 'imaps://1.2.3.4/Drafts;MAILINDEX=1' --user user:pass
|
|
```
|
|
Die e-pos indeks sal dieselfde indeks wees wat teruggegee word deur die soekoperasie.
|
|
|
|
Dit is ook moontlik om `UID` (unieke id) te gebruik om boodskappe te benader, maar dit is minder gerieflik aangesien die soekbevel handmatig geformateer moet word. Byvoorbeeld:
|
|
```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
|
|
```
|
|
Ook moontlik om net dele van 'n boodskap af te laai, bv. onderwerp en afstuurder van die eerste 5 boodskappe (die `-v` is nodig om die onderwerp en afstuurder te sien):
|
|
```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 '^<'
|
|
```
|
|
Alhoewel, dit is waarskynlik skoner om net 'n klein for-lus te skryf:
|
|
```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.
