The TASCAM X-48 and X-48mkII Hard Disk recorders run a cut-down, hardened version of the Windows XP Operating System, released in 2005.
As part of the X-48 feature set, it has the ability to share drive contents via SMB to other computers.
According to many news sites, the Ransomware "WannaCry" uses SMB to infect computers.
Please note that the X-48 and X-40mkIII do not normally operate in "drive sharing" mode, but we are currently investigating whether the WannaCry ransomware would be capable of infecting an X-48 or X-48mkII from another (infected) computer on the same network.
TASCAM is continuing to investigate this issue and will publish further information here as it becomes available. In the meantime, should you have any questions regarding the use of your TASCAM X-48 or X-48mkII, please contact your local TASCAM Customer Service team.
