Anti-phishing training is a method of educating users on how to identify and avoid phishing attacks, which are attempts to trick users into revealing sensitive information or performing malicious actions by impersonating legitimate entities or persons. Whaling attacks are a specific type of phishing attack that target high-level executives or influential individuals within an organization. Anti-phishing training can help users recognize the signs of whaling attacks and prevent them from falling victim to them. Screened subnet, firewall, and antivirus are not items that can directly address the issue of whaling attacks.

A full backup does not depend on any previous backups, unlike differential or incremental backups, which only save the changes made since the last backup. A synthetic backup is a type of full backup that combines an existing full backup with incremental backups to create a new full backup, but it still requires multiple backup sets to recover data. Therefore, a full backup is the most suitable for the payroll workstation that needs to have its data readily available and recoverable. You can learn more about the differences between full, differential, incremental, and synthetic backups from this article.

The best way for a technician to return the device to service safely is to reinstall the operating system. This is because the device is infected by ransomware, which is a form of malware that encrypts files and demands payment for decryption. Reinstalling the operating system will erase the ransomware and restore the device to its original state. However, this will also delete any data that was not backed up before the infection. Therefore, it is important to have regular backups of critical data and protect them from ransomware attacks1.

The other options are not effective or safe for ransomware recovery. Running an AV scan may not detect or remove the ransomware, especially if it is a new or unknown variant. Installing a software firewall may prevent future attacks, but it will not help with the current infection. Performing a system restore may not work if the ransomware has corrupted or deleted the restore points. Complying with the on-screen instructions is not advisable, as it will encourage the attackers and there is no guarantee that they will provide the decryption key after receiving the payment.

To prevent and recover from ransomware attacks, it is recommended to follow some best practices, such as234:

Use strong passwords and multifactor authentication for all accounts and devices.

Keep all software and firmware updated with the latest security patches.

Avoid opening suspicious or unsolicited emails and attachments.

Educate users and staff on how to recognize and report phishing and social engineering attempts.

Use antivirus software and enable real-time protection.

Enable network segmentation and firewall rules to limit the spread of ransomware.

Implement a Zero Trust security model to verify all requests and devices before granting access.

Create and test backups of critical data and store them offline or in a separate network.

Recover safely by isolating the infected devices, identifying the ransomware variant, and restoring data from backups.

Report any ransomware incidents to law enforcement agencies and seek help from experts.
