Pull your Western Digital My Book Live NAS off the internet now if you value your files

Storage giant fingers 'critical' bug allowing remote factory resets that wipe contents

Western Digital has alerted customers to a critical bug on its My Book Live storage drives, warning them to disconnect the devices from the internet to protect the units from being remotely wiped.

In an advisory, the storage firm said My Book Live and My Book Live Duo devices were being "compromised through exploitation of a remote command execution vulnerability" CVE-2018-18472. The exploit is described as a root remote command execution bug which can be triggered by anyone who knows the IP address of the affected device – and is currently being "exploited in the wild in June 2021 for factory reset commands."

At this time, we recommend you disconnect your My Book Live and My Book Live Duo from the Internet to protect your data on the device.

Reports of the issue emerged on Thursday after owners of the NAS devices took to Western Digital's support forums to complain.

"All my data is gone too. Message in GUI says it was 'factory reset' today! I am totally screwed without that data… years of it," wrote one user.

"I kept all my documents on this drive. All files gone," said another.

Device logs published on the Western Digital forums show the devices were remotely factory reset, although the culprits have not been found. In a statement earlier today, the company said it didn't believe its own servers were compromised.

The Western Digital My Book Live connects to a host computer via USB, with internet access coming via an Ethernet port on the back. Remote access is obtained via Western Digital's own cloud servers.

NAS drives have a storied history of falling victim to malicious actors. In April, Taiwanese storage giant QNAP urged customers to update their drives in the face of two specifically targeted ransomware strains, Qlocker and eCh0raix.

The previous year, authorities in the US and UK warned of a mass infection of data-stealing malware targeting QNAP drives. Dubbed Qsnatch, the attack compromised an estimated 62,000 devices. Once inside, the malware opened several backdoors – including SSH and a webshell – and resisted attempts by the owner to deploy firmware updates that would have resolved the problem.

Lenovo has similarly been caught with its pants down in the past, hastily issuing a firmware patch in 2019 for its Iomega-branded storage devices after a security flaw could have potentially seen the contents of drives exposed to the internet.

While details about the "how" and "why" of this particular incident are thin on the ground, Western Digital noted its My Book Live NAS devices last received a firmware update in 2015. In practice, this means almost seven years of security vulnerabilities that haven't been patched, leaving users at risk.

While Western Digital hasn't disclosed the scale of the problem, a quick search on Shodan shows over 200 My Book Live devices publicly accessible from the internet.

The Register has asked Western Digital to comment. ®

  • Meet Wizard Spider, the multimillion-dollar gang behind Conti, Ryuk malware
    Russia-linked crime-as-a-service crew is rich, professional – and investing in R&D

    Analysis Wizard Spider, the Russia-linked crew behind high-profile malware Conti, Ryuk and Trickbot, has grown over the past five years into a multimillion-dollar organization that has built a corporate-like operating model, a year-long study has found.

    In a technical report this week, the folks at Prodaft, which has been tracking the cybercrime gang since 2021, outlined its own findings on Wizard Spider, supplemented by info that leaked about the Conti operation in February after the crooks publicly sided with Russia during the illegal invasion of Ukraine.

    What Prodaft found was a gang sitting on assets worth hundreds of millions of dollars funneled from multiple sophisticated malware variants. Wizard Spider, we're told, runs as a business with a complex network of subgroups and teams that target specific types of software, and has associations with other well-known miscreants, including those behind REvil and Qbot (also known as Qakbot or Pinkslipbot).

  • Supreme Court urged to halt 'unconstitutional' Texas content-no-moderation law
    Everyone's entitled to a viewpoint but what's your viewpoint on what exactly is and isn't a viewpoint?

    A coalition of advocacy groups on Tuesday asked the US Supreme Court to block Texas' social media law HB 20 after the US Fifth Circuit Court of Appeals last week lifted a preliminary injunction that had kept it from taking effect.

    The Lone Star State law, which forbids large social media platforms from moderating content that's "lawful-but-awful," as advocacy group the Center for Democracy and Technology puts it, was approved last September by Governor Greg Abbott (R). It was immediately challenged in court and the judge hearing the case imposed a preliminary injunction, preventing the legislation from being enforced, on the basis that the trade groups opposing it – NetChoice and CCIA – were likely to prevail.

    But that injunction was lifted on appeal. That case continues to be litigated, but thanks to the Fifth Circuit, HB 20 can be enforced even as its constitutionality remains in dispute, hence the coalition's application [PDF] this month to the Supreme Court.

    FBI and co blow lid off latest PHP tampering scam

    The FBI and its friends have warned businesses of crooks scraping people's credit-card details from tampered payment pages on compromised websites.

    It's an age-old problem: someone breaks into your online store and alters the code so that as your customers enter their info, copies of their data is siphoned to fraudsters to exploit. The Feds this week have detailed one such effort that reared its head lately.

    As early as September 2020, we're told, miscreants compromised at least one American company's vulnerable website from three IP addresses: 80[.]249.207.19, 80[.]82.64.211 and 80[.]249.206.197. The intruders modified the web script TempOrders.php in an attempt to inject malicious code into the checkout.php page.
