I think this situation shows more the incompetence of the US cyber security apparatus, at least when it comes to securing critical systems.

With the OPM breach and the Equifax leak the Chinese have the personal details and biometrics of millions of Americans who work for the government in areas that handle sensitive information.

The Russians have already specifically identified US cyberwarfare individuals before. So, it can be done and has been done. With the information the Chinese already have it is very unlikely they could not do the same, but they'd gain very little from it. (The US doesn't gain much and should probably stop the practice also.)

We wouldn't know if China, Russia or whoever could identify specific US operators, only the US plays silly indictment games like this.

Russia did reveal at least one NSA TAO operative through their ShadowBrokers puppet account.

At least 4. But it's really not at all obvious that Shadow Brokers was Russia.

I don't see where your link points to this and I mean it's pretty obvious the Shadow Brokers were aligned with foreign policy interests of the Russian government. If it was another adversary, I don't see why they worked so hard to benefit mostly Russia.

>I don't see where your link points to this

Recently there's been a lot of speculation that Shadow Brokers were in fact the "second source". That may or may not be true.

It's really not. Unless everything anti-US fits that mould, but then we'd have a plenty of other governments to suspect too.

Why is indicting foreign nationals for hacking American citizens' data "silly"?

It doesn't achieve much, it increases the risk of revealing methods and sources. It also puts US cyber security personnel at greater risk, some of whom have spoken out against the practice.

For one thing, because there's no reason to suspect that any particular accusation in these indictments is true.
