As a followup post, here are some other institutions who have published their own commentary on the #OperationPacificRim research that @SophosXOps published today:

The FBI posted a bulletin seeking more information about the people behind the intrusions (Sophos has identified at least some of the individuals who were involved):

The UK's National Cybercrime Centre (NCSC) published their own research into malware they called #PygmyGoat (and which we named as "libsophos.so" in our report timeline (links to PDF):

My former Sophos colleague Kristin Del Rosso previously coauthored an article for the Atlantic Council on China-originated device intrusions as a direct result of this research:

@WIRED reporter @agreenberg published a great summary of the attack campaign:

Cybersecurity firm Greynoise also published their research. Greynoise has been a consistently supporting org.
