Bitcoin miner Dovecat is targeting network storage devices from Qnap and Synology

The Dovecat malware is currently nesting on NAS devices from Qnap and Synology and mining cryptocurrency at the expense of the victims’ computing power. Qnap has now published information about security. Synology has not yet issued a statement on this.

NAS owners have been reporting such attacks in the official forums of Qnap and Synology for months. The malware requires so much computing power that the devices can hardly be used.

Important security tips In a security warning, Qnap provides tips on how owners can secure their NAS against and other threats. It is particularly important that the current version with security updates of the QTS operating system is always installed. In addition, owners should ensure that they use strong admin passwords and no default ports (80, 443, 8080 and 8081).

In the support area you will find more detailed information including instructions on how to effectively secure network storage. For example, there is how to remove suspicious user accounts. These notes do not only apply to devices from Qnap.

At a point in time that has not yet been known, the developers want to provide a tool to remove Dovecat.

heise + | IoT hacking: improve firmware and network security

Software in embedded devices offers many points of attack. A systematic approach to securing and automated scanning of security gaps helps.

IoT hacking: Improve firmware and network security Secure update mechanisms Do not underestimate web applications Reduce the attack surface Silence services Article in iX 2 / 2021 read How can IoT software be implemented securely? Embedded firmware often contains sensitive data. This also applies to images that are downloaded to update the firmware. If you extract their data, you can use exposed web services, databases, file or terminal services to steal or manipulate further information.

The methods for securing memory modules represent a hurdle, but not a complete safeguard against access to the memory content. This can only be achieved almost completely by encrypting all content. However, the correct implementation must be ensured here. Experience has shown that important key material such as private keys are often unsecured, i.e. stored in plain text. If an attacker steals the key, he can decrypt the firmware without great difficulty.

The firmware used must be signed so that an attacker cannot manipulate the memory content or the firmware. This is the only way to verify the source as trustworthy. Particular attention should be paid to the boot loader. An attacker often succeeds in manipulating the boot process in such a way that it does not take into account downstream signatures of the kernel or the file system or starts an alternative operating system. Therefore the authenticity of the bootloader has to be checked in order to secure the following processes.
