TrendAI formalizes threat attribution as a structured, repeatable discipline by combining standardized evidence scoring, relationship mapping, and bias testing, with a temporary stage that separates clustering from final naming. Article on how we attribute: www.trendmicro.com/vinfo/us/sec...

comparison between this intrusion set and Void Rabisu
Website mimicking Trend Micro graphical design
We investigated an #APT with links to Void Rabisu (Romcom) that used Trend Micro updates as a lure in a recent campaign involving vulnerability exploitation. There were at least 4 stages before the final payload, some of them being tailored to the targeted machine www.trendmicro.com/en_us/resear...
There are some links from Earth Estries to Salt Typhoon but we don't have enough evidence to say there is 100% overlap
There is a typo in the link (remove the extra "7" at the end, will ask for it to be fixed, thanks!).
Regarding your question, this is what we wrote about Salt Typhoon in our third Earth Estries blogpost www.trendmicro.com/en_us/resear...
Earth Estries and Earth Naga malware links
List of Earth Estries and Earth Naga targets, classified by targeted industry and location
Collaboration types and the related MITRE tactic stage where such collaboration occurs
Earth Estries and Earth Naga malware toolkits
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...
Orange Cyberdefense saw the same threat and named the ransomware "NailaoLocker" orangecyberdefense.com/global/blog/.... They share interesting thoughts on the motivations of the ransomware deployment, although they don't have the final answer. We also saw no financial gain for the threat actor
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...
#APT
Intelligence Online links the MOONSHINE framework that we discussed in our Earth Minotaur report (www.trendmicro.com/en_us/resear...) to a Chinese company www.intelligenceonline.com/surveillance... (article is free but needs registration to access it). Happy new year UPSEC ! 😘
Since Aug 2024 Earth Koshchei (APT29, Midnight Blizzard) used 193 RDP relays and 34 rogue backends against military, MFAs and others. The campaign peak was likely preceded by barely audible campaigns that ended with a bang in Oct 2024. Details and indicators here: www.trendmicro.com/en_us/resear...
