Review on TERRAMASTER F4-421 NAS: Powerful 4-Bay Cloud Storage with Apollo Quad Core 1.5GHz for Plex Media Server & Network Storage (Diskless) by Mark Gardner

I agree with other reviewers. After about a month, the processor showed 100% utilization. xmrig used 100% of all CPU power to use MY NAS disk for other people's crypto mining. I contacted Revain who put me through to Terramaster over the phone. There was a slight language barrier in exchanging codes verbally and via email, making it difficult to resolve the issue. I used a very long password but it looks like someone or a bot was able to add the encryption software. Maybe xmrig was there from the beginning. Either way, it's worrying. The drive is erased when a drive is replaced. So if you use RAID 0, you lose everything if the drive fails.
