According to that Wikipedia page, The Equation Group refers to "a collection of tools used for hacking". Targeting hacking tools seems to me exactly what a security software company should be doing.
>Such an "innocent" company would have no reason to get involved in cyberwarfare between state-actors, while Kaspersky is heavily involved in such activities and pouring considerable resources into them.
Even if we assume these tools can only target governments and not businesses or individuals, perhaps Kaspersky wishes to obtain contracts with the governments targeted. I don't see how this is particularly sinister or illegitimate.
> This is especially damning since they are clearly targeting state-actors that are antagonistic to Russian interest, such as the US (Equation Group) and its allies (Israel)
Your Wikipedia link states: "The Shadow Brokers announced that it had stolen malware code from the Equation Group [...] Exploits against Cisco Adaptive Security Appliances and Fortinet's firewalls were featured in some malware samples released by The Shadow Brokers [...] Juniper also confirmed that its NetScreen firewalls were affected. The EternalBlue exploit was used to conduct the damaging worldwide WannaCry ransomware attack."
Three American companies and vast numbers of individual users and civil government institutions around the world (including the UK Health Service). Are they all Russian interests?
