Bitcoin Mining Pools Targeted in Wave of DDOS Attacks

AntPool, BW.com, NiceHash, CKPool and GHash are among a number of bitcoin mining pools and operations that have been hit by distributed denial-of-service (DDOS) attacks in recent days.
The incidents appear to have begun in the first week of March. For example, on 11th March, AntPool ownerBitmain sent an email to customers disclosing the DDOS attacks and advising external pool users to set up failsafe pools in the event of an outage.
According to many of the companies affected by the incidents, those behind the attacks demanded payment in bitcoin in return for stopping the attacks.
BW.com alerted customers via its official blog to possible service disruptions owing to DDOS attacks, but did not say whether or not a ransom notice had been sent. Other pools took to Bitcoin Talk to warn users about the DDOS attacks.
