APT 32

Overview

APT 32 is also known as Ocean Lotus, APT-C-00, SeaLotus, and Cobalt Kitty.  It is a suspected Vietnamese hacker group, active since 2014. It generally targets the entities considered hostile to Vietnameses nationalists interests. 

Hence, APT 32 targets the foreign companies doing business with Vietnam, Vietnamese government critics, local and ex-pat Vietnamese human rights activists, and rival South East Asian foreign governments, especially the Philippines and Cambodia. Its attacks often coincide with important contract and legal negotiations between foreign companies and the Vietnamese government. 

How Does It Works?

APT32 uses less sophisticated, distinct, and fully-featured commercially available tools and malware collection. They start with a highly customized spear-phishing campaigns containing malicious files attached to it. They are also laced with custom spyware toolkits, that can easily infect and steal information from macOS, Android, and Windows-based devices. 

METALJACK, Denis (or DenisRAT), Kerrdown, Windshield, Komprogo, and Soundbite are some malware strains exclusive to or closely associated with APT 32.

Tactics, Techniques, and Procedures

  • They hack the adversaries' websites to collect their information and track their user base. 

  • They use custom macOS malware with double extension technique or malicious Office macros written in the Perl programming language.

  • Make use of Facebook social networking to spread malware through social engineering attacks.

  • Cobalt Strike, a legitimate penetration testing tool is used as Command and Control (C2) spyware.

Prevention

Vigilant awareness about social engineering attacks, that prompts the victim to open files from an untrusted source, is the most effective way to prevent an APT32 attack. Organizations engaged with Vietnamese government should be more careful about any document or links posted in public social networking forums. 

Hence, user awareness training to educate internal staff about proper procedures for assessing as well as handling documents, and a full-fledged Defense-in-Depth-based cybersecurity program is the best way to prevent a successful APT32 attack.

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

Various organizational units may require a level of access to specific dashboards or sets of data. Microsoft Sentinel offers the ability to assign table-level permissions and limit the level of access to the minimum required to perform requisite job functions.  Role-based Access Control (RBAC) Requirements Microsoft Sentinel offers an extensive list of Azure built-in roles that can be used to provide granular access according to the job requirements and permitted level of access. Some of them are various Microsoft Sentinel dedicated roles: Microsoft Sentinel Contributor- Can perform all engineering-related configuration, such as creating alert rules, configuring data connectors, and additional similar tasks.  Microsoft Sentinel Reader- Can query the log data stor
