/ Have Your Cake and Eat it Too? An Overview of UNC2891

The Mandiant Advanced Practices team previously published a threat research blog post that provided an overview of UNC1945 operations where the actor compromised managed services providers to gain access to targets in the financial and professional consulting industries.
Since that time, Mandiant has investigated and attributed several intrusions to a threat cluster we believe has a nexus to this actor, currently being tracked as UNC2891. Through these investigations, Mandiant has discovered additional techniques, malware, and utilities being used by UNC2891 alongside those previously observed in use by UNC1945…

Note: DNS Proxy Mechanism updated on BLD DNS

Maybe as you know BLD DNS works on few ports in DoH mode - 443, 8443

You can use any of these ports in your browsers or devices, but I want to note you about how these modes work:

- 443 it is a native BLD service
- 8443 is is a reverse proxy (nginx or can be another service/mechanism)

⚡️ if you notice that some mode is not working properly, immediately as possible let me know about it - @sysadminkz

Example: How to setup Customised DNS your browser.

Settings > Privacy and security > Security > Use secure DNS > Customised:
- https://bld.sys-adm.in/dns-query
or
- https://bld.sys-adm.in:8443/dns-query
