QNAP wants its users to update Malware remover app after QSnatch Data-Stealing reports


QNAP urges its users to update Malware remover app after QSnatch Data-Stealing scenario

A malware threat dubbed QSnatch is known to target NAS (Network-Attached Storage) devices manufactured by the Taiwan-based QNAP Systems, Inc. Malware researchers at Finland’s National Cyber Security Center (NCSC-FI) were the first to spot the activity of this new threat in the middle of October 2019.

According to the reports, QNAP wants its users to update the Malware Remover app and bolster their NAS devices’ security following that the QSnatch malware is targeting QNAP NAS and attempting to obtain access. The finding of the Qsnatch by the two agencies have urged organizations to ensure their devices have not been previously compromised, and if so, run a full factory reset on the device before performing the firmware upgrade.

“Certain media reports claiming that the affected device count has increased from 7,000 to 62,000 since October 2019 are inaccurate due to a misinterpretation of reports from different authorities,” QNAP

“All QNAP NAS devices are potentially vulnerable to QSnatch malware if not updated with the latest security fixes. Further, once a device has been infected, attackers can prevent administrators from successfully running firmware updates.” the two agencies said

QNAP has updated its Malware Remover application for the QTS operating system on November 1, 2019, to detect and remove the malware from QNAP NAS and has also released an updated security advisory on November 2, 2019, to address the issue. Subsequently, QNAP has taken multiple actions (summarized as follows) to assist our users in defending data security:
