Database and Application Forensics

Refer to the exhibit. An analyst recovers this binary log entry from a MySQL server. What does the timestamp '190101 10:00:00' represent?

A forensic investigator is examining a compromised database server running Microsoft SQL Server 2019. The attacker gained access and executed several destructive queries. The investigator needs to determine the exact time and text of the malicious queries. The database is configured with the full recovery model, and transaction log backups are available. Which of the following should the investigator use to recover the query text?

You are a forensic investigator responding to an incident at a financial institution. The organization uses Microsoft SQL Server 2016 for its transaction processing system. The database is configured with full recovery model and transaction log backups are taken every 15 minutes. The incident response team has identified that an attacker gained access to the database server via compromised credentials and executed a series of malicious SQL statements, including data exfiltration and deletion of critical records. The time of the attack is estimated to be between 2:00 PM and 2:05 PM. The last full backup was taken at 12:00 AM (midnight) the same day. Transaction log backups are available for the entire day. The last transaction log backup before the attack was taken at 1:45 PM. The next transaction log backup after the attack was taken at 2:15 PM. The database is still online and being used by the business. Management wants to recover the database to a point just before the attack (2:00 PM) to minimize data loss, while preserving evidence for investigation. Which of the following actions should you take FIRST?

An organization uses Microsoft SQL Server 2019 with full recovery model. A database administrator accidentally executed a DROP TABLE statement. The transaction log was backed up immediately after the incident. Which forensic technique would allow the analyst to restore the dropped table?

During a database forensic investigation, an analyst recovers a MySQL binary log file (binlog.000012) from a compromised server. Which command should the analyst use to extract the actual SQL statements from this binary log in a human-readable format?

A forensic investigator is analyzing a Microsoft SQL Server instance that was compromised. The investigator wants to identify all login attempts that failed due to incorrect passwords. Which system function or view should be queried?

A forensic investigator is examining a MySQL database server that was compromised. The investigator needs to determine which user account was used to perform unauthorized modifications to a critical table. The MySQL server has the general query log enabled. Which of the following should the investigator review to find the user account associated with the modifications?

During a forensic investigation of a MongoDB database, the analyst needs to identify which user executed a particular write operation. Which MongoDB log or feature should the analyst examine?

Refer to the exhibit. A database administrator finds the above error log entries when attempting to start the MySQL service. The server was working fine yesterday. What is the most likely cause of this issue?
