Over 100,000 devices have a misconfigured service called multicast DNS that accepts requests from the Internet and can potentially be abused to amplify distributed denial-of-service (DDoS) attacks.
A hacker exploited publicly known vulnerabilities to install malware on network-attached storage systems manufactured by Synology and used their computing power to generate Dogecoins, a type of cryptocurrency.
I bought my first Synology NAS in 2006 -- the CS-406. The box was small, quiet, and better than the PC I was using as a do-it-myself file server. Speed was good and the product was well-designed. Much has changed in Synology products over the past six years, some for the good and some for the bad. The hardware is still solid and performance is still great, but I'm not sure I would recommend this NAS to a nontechnical business user. Other products in this class make setup and ongoing backup much easier.
