{% embed url="https://discord.gg/tryhardsecurity" %} *** ## Internet Message Access Protocol Die **Internet Message Access Protocol (IMAP)** is ontwerp om gebruikers in staat te stel om **hul e-pos boodskappe van enige plek af te bekom**, hoofsaaklik deur 'n Internet-verbinding. In wese word e-posse **op 'n bediener gehou** eerder as om afgelaai en op 'n individu se persoonlike toestel gestoor te word. Dit beteken dat wanneer 'n e-pos toegang verkry of gelees word, dit **direk van die bediener** gedoen word. Hierdie vermoë maak dit gerieflik om e-posse van **meerdere toestelle** te kontroleer, wat verseker dat geen boodskappe gemis word ongeag die toestel wat gebruik word nie. Standaard werk die IMAP-protokol op twee poorte: * **Poort 143** - dit is die standaard IMAP nie-geënkripteerde poort * **Poort 993** - dit is die poort wat jy moet gebruik as jy veilig met IMAP wil verbind ``` PORT STATE SERVICE REASON 143/tcp open imap syn-ack ``` ## Banner gryp ```bash nc -nv 143 openssl s_client -connect :993 -quiet ``` ### NTLM Auth - Inligtingsontsluiting As die bediener NTLM-authentisering (Windows) ondersteun, kan jy sensitiewe inligting (weergawe) verkry: ``` root@kali: telnet example.com 143 * OK The Microsoft Exchange IMAP4 service is ready. >> a1 AUTHENTICATE NTLM + >> TlRMTVNTUAABAAAAB4IIAAAAAAAAAAAAAAAAAAAAAAA= + TlRMTVNTUAACAAAACgAKADgAAAAFgooCBqqVKFrKPCMAAAAAAAAAAEgASABCAAAABgOAJQAAAA9JAEkAUwAwADEAAgAKAEkASQBTADAAMQABAAoASQBJAFMAMAAxAAQACgBJAEkAUwAwADEAAwAKAEkASQBTADAAMQAHAAgAHwMI0VPy1QEAAAAA ``` Of **automate** dit met **nmap** plugin `imap-ntlm-info.nse` ### [IMAP Bruteforce](../generic-methodologies-and-resources/brute-force.md#imap) ## Sintaksis IMAP Opdrag voorbeelde van [hier](https://donsutherland.org/crib/imap): ``` Login A1 LOGIN username password Values can be quoted to enclose spaces and special characters. A " must then be escape with a \ A1 LOGIN "username" "password" List Folders/Mailboxes A1 LIST "" * A1 LIST INBOX * A1 LIST "Archive" * Create new Folder/Mailbox A1 CREATE INBOX.Archive.2012 A1 CREATE "To Read" Delete Folder/Mailbox A1 DELETE INBOX.Archive.2012 A1 DELETE "To Read" Rename Folder/Mailbox A1 RENAME "INBOX.One" "INBOX.Two" List Subscribed Mailboxes A1 LSUB "" * Status of Mailbox (There are more flags than the ones listed) A1 STATUS INBOX (MESSAGES UNSEEN RECENT) Select a mailbox A1 SELECT INBOX List messages A1 FETCH 1:* (FLAGS) A1 UID FETCH 1:* (FLAGS) Retrieve Message Content A1 FETCH 2 body[text] A1 FETCH 2 all A1 UID FETCH 102 (UID RFC822.SIZE BODY.PEEK[]) Close Mailbox A1 CLOSE Logout A1 LOGOUT ``` ### Evolusie ``` apt install evolution ``` ![](<../.gitbook/assets/image (1033).png>) ### CURL Basiese navigasie is moontlik met [CURL](https://ec.haxx.se/usingcurl/usingcurl-reademail#imap), maar die dokumentasie is lig op besonderhede, so dit word 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. om te soek na konsepte met wagwoord in die e-posliggaam: ```bash curl -k 'imaps://1.2.3.4/Drafts?TEXT password' --user user:pass ``` 'n Goeie oorsig van die soekterme wat moontlik is, is [hier](https://www.atmail.com/blog/imap-commands/) geleë. 3. Laai 'n boodskap af (imap opdrag `SELECT Drafts` en dan `FETCH 1 BODY[]`) ```bash curl -k 'imaps://1.2.3.4/Drafts;MAILINDEX=1' --user user:pass ``` Die posindeks sal dieselfde indeks wees wat van die soekoperasie teruggegee word. Dit is ook moontlik om `UID` (unieke id) te gebruik om boodskappe te bekom, maar dit is minder gerieflik aangesien die soekopdrag 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 sender van die eerste 5 boodskappe (die `-v` is vereis om die onderwerp en sender 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 bietjie vir-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 ``` ## Shodan * `port:143 CAPABILITY` * `port:993 CAPABILITY` **Try Hard Security Group**

Protocol_Description: Internet Message Access Protocol #Protocol Abbreviation Spelled out Entry_1: Name: Notes Description: Notes for WHOIS 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. https://book.hacktricks.xyz/pentesting/pentesting-imap Entry_2: Name: Banner Grab Description: Banner Grab 143 Command: nc -nv {IP} 143 Entry_3: Name: Secure Banner Grab Description: Banner Grab 993 Command: openssl s_client -connect {IP}:993 -quiet Entry_4: Name: consolesless mfs enumeration Description: IMAP enumeration without the need to run msfconsole Note: sourced from https://github.com/carlospolop/legion Command: msfconsole -q -x 'use auxiliary/scanner/imap/imap_version; set RHOSTS {IP}; set RPORT 143; run; exit' ``` {% hint style="success" %} Leer & oefen AWS Hacking:[**HackTricks Opleiding AWS Red Team Expert (ARTE)**](https://training.hacktricks.xyz/courses/arte)\ Leer & oefen GCP Hacking: [**HackTricks Opleiding GCP Red Team Expert (GRTE)**](https://training.hacktricks.xyz/courses/grte)
