This week the Taiwanese vendor QNAP has published an alert urging users to secure their devices after a growing number of users reported that their devices have been hit by brute-force attacks.
“With increasing reports of brute-force attacks, QNAP urges its users to take immediate action to enhance the security of their devices.” reads the alert published by the vendor. “Recently QNAP has received multiple user reports of hackers attempting to log in to QNAP devices using brute-force attacks – where hackers would try every possible password combination of a QNAP device user account.”
The vendor suggests actions like using strong passwords, changing the default access port number, and disabling any admin account. The company also suggests avoiding exposing their devices on public networks avoid using default network ports for public services.
“Other steps to strengthen the security of QNAP appliances and mitigate brute-force attacks include setting complex (strong) passwords for user accounts, enabling password policies, and disabling the admin account.” continues the alert.
Additional steps that users can take to ensure that their devices are not targeted include keeping them away from public networks and ensuring that no default network ports are used for public services.
Furthermore, QNAP recommends that users set complex passwords for their accounts, that password policies are enabled, and that the admin account is disabled. These steps, the company says, can improve device security and mitigate brute-force attacks.
The Taiwanese manufacturer also published a FAQ page that explains how to detect unauthorized login attempts on a device, and how to prevent attackers from compromising the device.
