Western Digital asks users to unplug their My Book Live drives from the internet following mass data wipes

A hot potato: Imagine the horror of waking up one day and discovering that your cloud-connected external backup drive has lost all data and factory reset itself. Unfortunately, that’s exactly what’s happened to an unknown number of WD My Book Live users whose drives have been wiped clean after being compromised by malicious software. Since the threat is still active, WD is advising owners to unplug their drives from the internet as it investigates the incident.

WD My Book Live users are strongly advised to disconnect their drives from the internet following reports of widespread data wipes. The affected devices appear to be the consumer-focused NAS models – My Book Live and My Book Live Duo – that were apparently compromised by malicious software and remotely triggered to perform a factory reset.

As ArsTechnica notes, user complaints started pouring in on the WD’s support forum, where some customers report being unable to access their WD Live accounts once the drive had been wiped clean. So far, none have managed to recover their lost data. One user also posted a log that showed a remote factory reset had taken place without their permission.

Although offline backups is one of the recommended strategies for keeping data safe, most users tend to buy these types of cloud-connected drives to store, backup and access their files across devices. Another user reported being unable to access their files via the iPhone app.

Tried to access some files via the iPhone app but got an error message saying “unable to connect”. Assumed it was just a Wi-Fi/network issue but when I tried to access the drive from my PC using a shortcut everything was gone except for (empty) default Public folders: Shared Music, Shared Pictures, Shared Videos and Software.

The time stamps on those folders say they were created at 00:16 (UK time) this morning.

There is also a .tickle file created at 00:17.

I can’t log into the UI on the device as it says my password is invalid.

The company says it is actively investigating the incident and found no indications of a breach or compromise of its cloud services or systems. “We have determined that some My Book Live devices have been compromised by a threat actor. In some cases, this compromise has led to a factory reset that appears to erase all data on the device. The My Book Live device received its final firmware update in 2015.”

Launched in 2011, WD dropped support for the My Book Live/Live Duo four years later. It’s quite possible that the ‘threat actor’ exploited a vulnerability that remains unpatched to this day. Despite being discontinued in 2015, the drives can still be found for purchase online. Users looking for this type of external storage typically expect the hardware to fail first, however, compromised software can be equally damaging when it comes to cloud-connected drives.
