Question 182

A developer reports that a workstation's database file extensions have been changed from .db to .enc. The developer is also unable to open the database files manually. Which of the following is the best option for recovering the data?

A.Accessing a restore point
B.Rebooting into safe mode
C.Utilizing the backups
D.Using an AV to scan the affected files

Correct Answer: C

Explanation
The scenario described in the question suggests that the workstation has been infected by a ransomware, which is a type of malware that encrypts the files on the target system and demands a ransom for the decryption key12. The file extension .enc is commonly used by some ransomware variants to mark the encrypted files34.
The developer is unable to open the database files manually because they are encrypted and require the decryption key, which is usually held by the attacker.
The best option for recovering the data is to utilize the backups, assuming that the backups are recent, valid, and not affected by the ransomware. Backups are copies of the data that are stored in a separate location or device, and can be used to restore the data in case of a disaster, such as a ransomware attack . By restoring the data from the backups, the developer can avoid paying the ransom and losing the data permanently.
Accessing a restore point is not a good option, because restore points are snapshots of the system settings and configuration, not the data files. Restore points can help to undo some system changes, such as installing a faulty driver or software, but they cannot recover the encrypted data files .
Rebooting into safe mode is also not a good option, because safe mode is a diagnostic mode that allows the system to run with minimal drivers and services, but it does not affect the data files. Safe mode can help to troubleshoot some system issues, such as malware infections, but it cannot decrypt the data files .
Using an AV to scan the affected files is also not a good option, because an AV is a software that can detect and remove some malware, but it cannot decrypt the data files. An AV can help to prevent or remove some ransomware infections, but it cannot recover the encrypted data files .
