Attackers DDoS WannaCry Kill Switch (venturebeat.com)

An anonymous reader quotes VentureBeat: As of late Friday, after many of the deadlines threatening data deletion had passed, few victims had paid ransoms. According to Elliptic Enterprises, only about $94,000 worth of ransoms had been paid via Bitcoin, which works out to less than one in a thousand of the 300,000 victims who were reportedly affected by WannaCry... While not as bad as feared, ransomware (not to mention cybersecurity threats in general) isn't going away. Wired reported that the domain registered by Hutchins has been under intense denial-of-service attacks delivered by an army of IoT devices marshalled, zombie-like, by Mirai.
