Itifaki ya Kufikia Ujumbe wa Mtandao
Itifaki ya Kufikia Ujumbe wa Mtandao (IMAP) imeundwa kwa lengo la kuruhusu watumiaji kufikia ujumbe wao wa barua pepe kutoka mahali popote, hasa kupitia muunganisho wa Mtandao. Kimsingi, barua pepe zinabaki kwenye server badala ya kupakuliwa na kuhifadhiwa kwenye kifaa cha mtu binafsi. Hii inamaanisha kwamba wakati barua pepe inapofikiwa au kusomwa, inafanywa moja kwa moja kutoka kwenye server. Uwezo huu unaruhusu urahisi wa kuangalia barua pepe kutoka kwenye vifaa vingi, kuhakikisha kwamba hakuna ujumbe unaopotea bila kujali kifaa kilichotumika.
Kwa chaguo-msingi, itifaki ya IMAP hufanya kazi kwenye bandari mbili:
- Bandari 143 - hii ni bandari isiyo salama ya IMAP ya chaguo-msingi
- Bandari 993 - hii ndio bandari unayohitaji kutumia ikiwa unataka kuunganisha kwa kutumia IMAP kwa usalama

NTLM Auth - Kufichua Taarifa
Ikiwa server inaunga mkono NTLM auth (Windows) unaweza kupata taarifa nyeti (toleo):
root@kali: telnet example.com 143
* OK The Microsoft Exchange IMAP4 service is ready.

CURL
Uvumbuzi wa msingi unawezekana na CURL, lakini nyaraka zina maelezo machache hivyo ni vyema kuangalia chanzo kwa maelezo sahihi.
- Orodha ya sanduku la barua (amri ya imap `LIST "" "*")
curl -k 'imaps://1.2.3.4/' --user user:pass
- Kupanga ujumbe kwenye sanduku la barua (amri ya imap
SELECT INBOXna kishaSEARCH ALL)
curl -k 'imaps://1.2.3.4/INBOX?ALL' --user user:pass
Matokeo ya utafutaji huu ni orodha ya viashiria vya ujumbe.
Pia niwezekano wa kutoa vigezo vya utafutaji vya kina zaidi. k.m. kutafuta rasimu zenye nenosiri kwenye mwili wa barua:
curl -k 'imaps://1.2.3.4/Drafts?TEXT password' --user user:pass
- Kupakua ujumbe (amri ya imap
SELECT Draftsna kishaFETCH 1 BODY[])
curl -k 'imaps://1.2.3.4/Drafts;MAILINDEX=1' --user user:pass
Mail index itakuwa index ile ile itakayorudishwa kutoka kwa operesheni ya utafutaji.
Pia niwezekano kutumia UID (kitambulisho cha kipekee) kufikia ujumbe, hata hivyo ni chaguo duni kwani amri ya utafutaji inahitaji kuandaliwa kwa mkono. K.m.
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
Pia, inawezekana kupakua sehemu tu ya ujumbe, kwa mfano mada na mtumaji wa ujumbe wa kwanza 5 ( -v inahitajika kuona mada na mtumaji):
$ curl -k 'imaps://1.2.3.4/INBOX' -X 'FETCH 1:5 BODY[HEADER.FIELDS (SUBJECT FROM)]' --user user:pass -v 2>&1 | grep '^<'
Ingawa, ni safi zaidi kuandika kitanzi kidogo:
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

Note: |
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.
