Taarifa Msingi
Itifaki ya Posta ya Ofisi (POP) inaelezwa kama itifaki ndani ya uwanja wa uunganishaji wa kompyuta na Mtandao, ambayo hutumiwa kwa ajili ya kutoa na kupata barua pepe kutoka kwenye seva ya barua pepe ya mbali, ikifanya iwezekane kwenye kifaa cha ndani. Iliyowekwa ndani ya safu ya maombi ya mfano wa OSI, itifaki hii inawezesha watumiaji kupata na kupokea barua pepe. Uendeshaji wa wateja wa POP kawaida unajumuisha kuanzisha uhusiano na seva ya barua pepe, kupakua ujumbe wote, kuhifadhi ujumbe huu kwa kifaa cha mteja kwa ndani, na kisha kuuondoa kutoka kwenye seva. Ingawa kuna matoleo matatu ya itifaki hii, POP3 inaonekana kuwa toleo linalotumiwa sana.

Post Office Protocol (POP)
POP is a protocol used by email clients to retrieve emails from a mail server. During a penetration test, you can attempt to brute force POP credentials, conduct user enumeration, or even capture credentials by sniffing network traffic. Additionally, you can look for misconfigurations that may lead to unauthorized access to POP accounts.

Description: Notes for POP
Note: |
Post Office Protocol (POP) is described as a protocol within the realm of computer networking and the Internet, which is utilized for the extraction and retrieval of email from a remote mail server**, making it accessible on the local device. Positioned within the application layer of the OSI model, this protocol enables users to fetch and receive email. The operation of POP clients typically involves establishing a connection to the mail server, downloading all messages, storing these messages locally on the client system, and subsequently removing them from the server. Although there are three iterations of this protocol, POP3 stands out as the most prevalently employed version.
