I think this is what is being attempted:
It happens that some devices that create signatures ECDSAin the Bitcoin blockchain can partially disclose bytes of information about the value "K" (NONCES)

Can someone explain this to me? It would seem that the headline is misleading. Bitcoin's encryption isn't under attack, correct? Just certain dockers encryption?

The Pollard’s Kangaroo interval ECDLP solver algorithm appears to be an attempt to break the SECP256K1 encryption which is used by Bitcoin to implement its public key cryptography. The TeamTNT group is using the computational power of the compromised targets to run the ECDLP solver.
So no, I don't think the headline is misleading. Only that "under attack" doesn't really mean much. They can try their luck if they want. I am confident in the underlying crypto.
In other words: Bitcoin's "encryption" has been under attack for ever

the article isn’t very clear, but it sounds like its malware that distributes and coordinates an ECDLP Solver. This looks like they’re targeting specific keys, not trying to break ecdsa generally.
In other words, they’re building a big botnet to try to find private keys for known (probably big-value) Bitcoin public keys
