Kaspersky isn't just a credible lab. They were, and remain, the best antivirus provider, by their results on basically any and all test batteries. Similarly their founder (Eugen Kaspersky - I assume who you are referencing with "YK") has never worked for the KGB. He was educated at at a KGB affiliated school and afterwards went to work for the Ministry of Defense. Within a few years the USSR collapsed and he then went, and stayed, within the private sector. But most importantly - companies (let alone other governments) providing detailed information on how other governments' cyber operations is most certainly not a thing that's done. That report I linked to is not just speaking in evidence free vagaries of the geopolitical 'leak' type you are alluding to. It provided extensive operational details and includes things such as even naming a specific driver as which is implied as being a Windows backdoor with plausible deniability. They chose to publish it letting the NSA know exactly which methods had been discovered, how they were discovered, and even exact versions they detected and potentially on exactly which machines (if the NSA salts binaries), given that the hash/date info were also provided. All of this is immensely valuable information that could have been both weaponized and 'defensized' for Russian cyber purposes. Providing it helped the NSA more than anybody. Outside of Trumpian 5d chess, there's no rational explanation for this, if one assumes they are in any meaningful way controlled by the Russian government.
