They generally targets Government-owned companies as well as the ministries of foreign affairs, science and technology of various countries like Australia, the Philippines, Vietnam, Thailand, Myanmar, Brunei, etc. There attacks have increased since 2019 with the help of the other APTs, and their victims' network serves as the command and control (C2) server.

  • Firstly, it pose its email and document as an official government one with the required information for the target (which is generally the data stolen from the other compromised systems).

  • Then, it adds a downloader to the document for Aria-body in order to gain access to the target's network.

  • After the successful completion of the above steps, it starts to make use of the victim's own servers to continue its attack against the other targets of interest.

If it is being considered to be used, then following areas should be covered during a Microsoft Sentinel deployment project: Consider the timelines and the strategy for a migration to AMA (Azure Monitor Agent) before the MMA end-of-life.  Consider the central deployment and management methodology for MMA. Determine which endpoints are in scope for deployment as these affect the log ingestion volume significantly.  Azure Monitor Agent (AMA) Organizations with MMA as the main Microsoft Sentinel agent should start planning the migration to AMA as soon as possible to avoid a rushed migration. One of the main advantages of AMA is the ability to control the log collection policy centrally and apply different policies against different groups of computers, re
