QNAP: Dovecat Malware Threatens NAS Security with High CPU Use

The Dovecat Monero-mining malware doesn't steal data, but it consumes large amounts of CPU and memory. This is the latest threat faced by QNAP customers - after research published in July 2020 identified that tens of thousands of NAS drives are potentially vulnerable to malware that prevents administrators from applying patches.

QNAP has warned its customers that their network-attached storage (NAS) drives might be susceptible to infection by a malware strain known as Dovecat, which infects devices and silently mines cryptocurrency.

The firm has issued a security advisory warning its users about Dovecat, which might infect NAS devices when they’re connected to the internet with weak passwords, according to QNAP’s analysis.
