[German]Just recently, QNAP NAS drives were encrypted by a ransomware attack – I went into this topic in the blog post The The QNAP disaster: Ransomware attack on NAS devices. Now the next attack is due. The vendor has again issued a security warning about its QNAP products as of April 29, 2021. There are indications that the devices or NAS drives are being actively attacked by the AgeLocker ransomware and the drive contents are being encrypted. The manufacturer is investigating these cases and asks users to update the systems. about the issue.
I was made aware of the new security issue a few hours ago via a Facebook comment there on my post QNAP NAS ransomware attack wrap-up (April 2021). Thomas U. wrote:
