This campaign relies heavily on social engineering to compromise targets. It is therefore essential to ensure that
personnel most likely to be approached - particularly roles in IT (developers, system administrators, helpdesk
teams) and Human Resources - are fully aware of the common tactics used, emphasizing on how threat actors
frequently tailor job-themed lures and impersonate recruiters.
One of the campaign’s notable initial access techniques involves using WhatsApp Desktop to deliver malicious
content and initiate further social engineering exchanges. Restricting the use of WhatsApp Desktop as well as
other similar instant messaging applications within the corporate environment or implementing monitoring
controls to detect suspicious activity related to this application, can help disrupt this initial access vector.
It is also possible to identify and block potentially malicious software executed through DLL sideloading by using
application control solutions capable of blocking suspicious DLL loads by legitimate software.
For organizations with an elevated risk profile, security operations teams should proactively search for known
indicators associated with DPRK activity clusters. Regular threat hunting using relevant IOCs, behavioral
patterns, and TTPs improves early detection and limits dwell time in the event of attempted compromise.
As a relevant hunting approach, you can for instance search for legitimate executables like SumatraPDF or
TightVNC being created and executed inside the user’s personal directory (ie. Downloads, %TEMP%, …). You
can also hunt for unexpected DLL loaded from non-standard directories.
Orange Cyberdefense’s Datalake platform provides access to Indicators of Compromise (IoCs) related to this
threat, which are automatically fed into our Managed Threat Detection services. This enables proactive hunting for
IoCs if you subscribe to our Managed Threat Detection service that includes Threat Hunting.
Orange Cyberdefense’s Managed Threat Intelligence service offers the ability to automatically feed network-related IoCs into your security solutions. To learn more about this service and to find out which firewall, proxy,
and other vendor solutions are supported, please get in touch with your Orange Cyberdefense Trusted Solutions
representative.
The Orange Cyberdefense Computer Security Incident Response team (CSIRT) provides emergency
consulting, incident management, and technical advice to help customers handle a security incident from initial
detection to closure and full recovery. If you suspect being attacked, do not hesitate to call our hotline.
