Network-attached storage (NAS) manufacturer Synology fixed several vulnerabilities in its devices' software, one of which could allow attackers to compromise the data stored on them.
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.
