Does anyone notice anything unusual about a number of the top miners on ethermine at the moment:

http://ethermine.org/miners/0ef177da88284818096351a26c6f35c00bf11480

Note that each of those addresses is reporting a HUGE amount of individual mining nodes and some of the addresses also match up with malware databases.
