Regarding your question, this is what we wrote about Salt Typhoon in our third Earth Estries blogpost www.trendmicro.com/en_us/resear...

We saw Earth Estries, an advanced #APT intrusion set, sharing its access to Earth Naga (Flax Typhoon). We introduce the term "Premier Pass" to describe this behavior, and propose a four-tier classification framework for collaboration types among advanced groups www.trendmicro.com/en_us/resear...

For incident responders, remember to retrieve the volume serial number where #Shadowpad was deployed, since it is used to encrypt the payload in the registry. Those serial numbers can also be found in LNK and Prefetch files in case you don't have live access to the host anymore

We released a report on an updated version of #Shadowpad including anti-debugging features and new configuration structure, that in some cases deploy a custom ransomware family. We have mainly seen the manufacturing industry being targeted in Europe and Asia www.trendmicro.com/fr_fr/resear...
