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
Thanks for the explanation
