NEW QUESTION # 23
Steve, a professional hacker, attempted to hack Alice's banking account. To accomplish his goal, Steve used an automated tool to guess Alice's login credentials. The tool uses a trial-and-error method by attempting all possible combinations of usernames and passwords to determine the valid credentials.
Identify the type of attack initiated by Steve in the above scenario.
Answer: B
Explanation:
The scenario describes an automated, trial-and-error attempt that triesall possible combinations of usernames and passwordsuntil a correct credential pair is found. This is the defining characteristic of abrute-force attack.
In digital forensics terminology, brute force is a direct password-guessing method that relies on exhaustive attempts (or systematically generated candidates) rather than tricking the user or exploiting a software flaw.
Investigators commonly recognize brute-force activity through artifacts such as repeated authentication failures in security logs, high-frequency login attempts from a single IP or distributed sources, account lockout events, and abnormal spikes in authentication traffic. In banking and web environments, it may also appear as repeated POST requests to login endpoints with varying credential pairs and consistent user-agent patterns, sometimes accompanied by throttling or CAPTCHA triggers.
The other options do not match the described "attempting all possible combinations" behavior.
Phishingobtains credentials by deception (fake emails/sites). ATrojan horsesteals data by running malicious code on the victim's system.Data manipulationfocuses on altering data integrity rather than credential guessing. Therefore, the correct attack type isBrute-force attack (A).
NEW QUESTION # 24
Harry, a security professional, was hired to identify the details of an attack that was initiated on a Windows system. In this process, Harry decided to check the logs of currently running applications and the information related to previously uninstalled or removed applications for suspicious events.
Which of the following folders in a Windows system stores information on applications run on the system?
Answer: A
Explanation:
On Windows systems, thePrefetchfeature records execution-related artifacts to speed up subsequent program launches. When an executable is run, Windows often creates a.pf prefetch fileinC:\Windows\Prefetchthat contains valuable forensic indicators such as the executable name (mapped into the prefetch filename), last run time(s) (depending on Windows version), run count (in many versions), and a list of files and directories referenced during startup. Because these artifacts can persist even after an application is lateruninstalled or deleted, investigators commonly use the Prefetch directory to demonstrate that a program executed on a host and to help build timelines around suspicious activity. This is especially useful in intrusion investigations for identifying the execution of attacker tools, droppers, scripts launched via interpreters, or renamed binaries.
The other options are not standard repositories for program execution history.C:\Windows\debugmay contain specific debug logs for certain components but is not the canonical execution-tracking folder.C:
\Windows\BookandC:\subdirare not standard Windows forensic artifact locations. Therefore, the folder that stores information on applications run on the system isC:\Windows\Prefetch (C).
NEW QUESTION # 25
A government organization decided to establish a computer forensics lab to perform transparent investigation processes on highly sensitive cases. The organization also decided to establish strong physical security around the premises of the forensics lab.
Which of the following security measures helps the organization in providing strong physical security to the forensics lab?
Answer: C
Explanation:
Forensics labs handling highly sensitive investigations must protect evidence confidentiality and prevent unauthorized disclosure. Strong physical security includes not only access control and surveillance, but also protections againstelectromagnetic (EM) emanationrisks. Computers and displays can unintentionally emit electromagnetic signals that, under certain conditions, may be intercepted and reconstructed to reveal sensitive information (for example, case notes, recovered evidence content, or credentials). Digital forensics lab design guidance recognizes this as a real threat in high-sensitivity environments and recommendsEM shielding / TEMPEST-style controlswhere appropriate. Shielding workstations reduces the chance of data leakage through side-channel interception and helps ensure that confidential investigative activities cannot be monitored from outside controlled areas.
The other options directly weaken physical security and safety. Fire extinguishers are required for facility safety and risk management, so "never place" them is unsafe and contrary to secure lab standards. Not maintaining an entrance log register undermines chain-of-custody support and accountability by removing a basic access auditing mechanism. "Never keep the lab under surveillance" removes a core deterrent and detection control for unauthorized entry, evidence tampering, and theft. Therefore, shielding workstations from transmitting electromagnetic signals is the only option thatstrengthensphysical security for a sensitive forensics lab.
NEW QUESTION # 26
Below is the syntax of a command-line utility that displays active TCP connections and ports on which the computer is listening.
netstat [-a] [-e] [-n] [-o] [-p Protocol] [-r] [-s] [Interval]
Identify the netstat parameter that displays active TCP connections and includes the process ID (PID) for each connection.
Answer: B
Explanation:
In Windows forensics and incident response, investigators often need to linknetwork activity(remote IPs, ports, connection states) to theresponsible processto determine whether traffic is legitimate or associated with malware, unauthorized tools, or data exfiltration. The Windowsnetstatutility can enumerate current TCP connections and listening ports, but the key flag that enables attribution to a running program is-o. The-o parameter instructs netstat to include theOwning Process ID (PID)with each connection or listening socket.
Once the PID is known, examiners can correlate it with process listings (e.g., Task Manager,tasklist, memory forensics output) to identify the executable name, path, user context, and parent process-critical steps in reconstructing attacker behavior and persistence.
The other options do not provide PID mapping:-nshows addresses and ports in numeric form (useful for speed and to avoid DNS lookups),-adisplays all connections and listening ports but without PID attribution by itself, and-sshows protocol statistics rather than per-connection ownership. Therefore, the parameter that shows active connectionsandincludes the PID for each is[-o](Option C).
NEW QUESTION # 27
Which of the following file systems of Windows replaces the first letter of a deleted file name with the hex byte code "e5h"?
Answer: D
Explanation:
InFAT (File Allocation Table)file systems (FAT12/16/32), directory entries are fixed-size records that include an8.3 filename field. When a file is deleted, FAT typically does not immediately erase the file's content; instead, it marks the directory entry as deleted by replacing thefirst character of the filenamewith the special marker byte0xE5(often written asE5h). This is a key forensic behavior because it means the file's metadata entry may still be present in the directory table, and the data clusters may remain recoverable until they are reused and overwritten. Examiners can often reconstruct the original filename's first character only through context or by correlating other artifacts, but the remainder of the directory entry (timestamps, size, starting cluster) can still assist recovery.
The other options do not match this mechanism.NTFSuses Master File Table records and marks deletions differently (file record flags and index changes), not by overwriting the first filename byte with E5h.EFSis an encryption feature layered on NTFS, not a distinct file system deletion marker.FHSis a UNIX/Linux directory layout standard, unrelated to Windows disk structures. Therefore, the correct answer isFAT (A).
