EC-COUNCIL 312-49v11 Value Pack (Frequently Bought Together)

During a forensic investigation of a cyberattack, the team is tasked with reconstructing the timeline of events to trace the attacker's actions within the compromised network. However, as they delve into system logs and critical documents, the forensic team notices discrepancies - files that should have been altered during the attack show timestamps indicating they were modified after the attacker had already left the system. Backup and system logs further reveal unusual patterns, with some files appearing to have been modified during regular operational hours, suggesting tampering to conceal the true sequence of events.
These inconsistencies raise suspicions among the investigators that the attacker may have intentionally manipulated the timestamps of critical files to disrupt the forensic timeline. This tactic, aimed at confusing the team and hindering their ability to reconstruct the breach, points to a deliberate effort to mislead the investigation, making it appear as though the malicious activities were part of normal operations. Which anti-forensics technique does this behavior most likely represent?

• A. Program packers to compress and conceal executable files, making them harder to analyze.
• B. Artifact wiping to remove all traces of unauthorized activity from the system.
• C. Alternate Data Streams (ADS) to store and hide malicious files in a way that avoids detection.
• D. Trail obfuscation by corrupting the file metadata.

In a large-scale healthcare breach in Boston, forensic investigators must archive several terabytes of compromised patient records for long-term evidence preservation. Since the data will be written once as forensic images and accessed infrequently, analysts require the storage technology that offers maximum capacity at lower cost, even if endurance and performance are reduced. What type of NAND flash memory is in the seized SSD best meets this forensic requirement?

• A. Single-level cell (SLC)
• B. Multi-level cell (MLC)
• C. Quad-level cell (QLC)
• D. Triple-level cell (TLC)

Martha, a CHFI professional, is assigned a significant case involving a cyber-attack on a major online retail company. Martha is tasked with gathering and examining the digital evidence associated with this attack. However, the retail company has a global presence with servers located in different jurisdictions worldwide. Considering the ACPO Principles of Digital Evidence, what should Martha's primary concern be when dealing with this multi-jurisdictional case?

• A. Store all gathered evidence on her local workstation
• B. Focus solely on the servers located in her jurisdiction
• C. Coordinate with local authorities in each jurisdiction to gather evidence
• D. Forego the need for consent and start investigating all servers immediately

During an investigation, an examiner opens an Excel file with a .xism extension, indicating that the document is capable of containing malicious code. Upon closer inspection, the investigator must determine if the file poses a threat. What should the investigator focus on to identify potential risks?

• A. Check if any streams in the file are labeled as containing macros.
• B. Inspect the metadata of the file for details about its author, creation date, and last modification.
• C. Inspect the file to see if any external resources, such as links or network calls, are embedded in the document.
• D. Check the file size to determine if it is unusually large or small, as this might indicate hidden data.

Following a data breach at a global financial institution, the company's incident response team has been working tirelessly to identify the breach's origin. The database administrator noticed that some tables within the company's SQL Server database were altered. She found that there were changes made in the order history, financials, and customer details. The transaction log showed modifications with numerous queries which were quite uncommon. It seemed the attacker gained access via a remote connection, suggesting that the login details might have been compromised.
As a forensic investigator, what would be your next step to identify the source of the breach?

• A. You would need to evaluate the server logs for unusual login patterns.
• B. You would need to assess the most recently accessed files.
• C. You would need to perform a complete system scan.
• D. You would need to identify the source IP from where the connection was initiated.
