Q&A

• What security measures and strategies are advised for protecting NAS systems?

  Setting up firewall rules to control access, limiting NAS capabilities for security, staying up to date with patches, using strong passwords, and enabling two-factor authentication are essential security measures to protect NAS systems from unauthorized access and potential attacks.

• How can unwanted traffic be reduced, and access to NAS be restricted based on geographical location?

  Changing the default port can reduce unwanted traffic, and geo-blocking can effectively limit access to NAS based on geographical location. Additionally, setting up firewall rules to restrict access based on location or allowing access from specific countries or regions are effective methods.

• What are the recommended tips to improve NAS security?

  To enhance NAS security, it is recommended to disable the admin account, enable adaptive Multi-Factor Authentication (MFA), consider two-factor authentication, and change port numbers for obscurity to reduce vulnerability to attacks and unauthorized access attempts.

• What are the methods used by hackers to attempt breaking into NAS and what security measures can mitigate these attempts?

  Hackers attempt to gain admin access, utilize multiple IP addresses to evade auto block, and target admin usernames through dictionary attacks. To mitigate these attempts, it's important to disable the admin account, enable auto block with restrictive settings, and activate account protection to prevent unauthorized login attempts.

• How can personal data be safeguarded against the botnet's activities?

  To protect personal data and prevent identity theft, using solutions like 'delete me' can help safeguard against the encryption of files and unauthorized access attempts by the botnet.

• What is the botnet targeting and how does it operate?

  The botnet, created by hacked devices, targets systems worldwide by exploiting insecure IoT devices and routers. It attempts to gain access through open Port 5000 or 50001, encrypts files, and demands ransom in Bitcoin.
