EC-COUNCIL EC-Council Digital Forensics Essentials (DFE) 112-57 Prüfungsfragen mit Lösungen (Q44-Q49):

44. Frage
Which of the following techniques is defined as the art of hiding data "behind" other data without the target's knowledge, thereby hiding the existence of the message itself?

Antwort: D

Begründung:
Steganographyis the technique of concealing a messagewithin another seemingly harmless carrier(such as an image, audio file, video, or document) so that theexistence of the hidden message is not apparentto an observer. Digital forensics references distinguish steganography from encryption: encryption scrambles content but usually leaves visible indicators that protected data exists (ciphertext), while steganography aims to make the communication look ordinary, reducing suspicion. In practice, steganographic methods often embed data into redundant or less perceptible parts of the carrier, such as modifying least significant bits in pixel values, altering frequency components in audio, or inserting data into metadata or unused file structures.
The other options do not match the definition.Password crackingis an access technique to recover authentication secrets, not a concealment method.Artifact wipingis an anti-forensics method intended to remove traces (logs, files, slack space remnants), but it does not "hide behind" other data-it destroys or overwrites evidence.Program packerscompress/obfuscate executables to hinder static analysis and detection, but they still produce an executable whose presence is evident; they do not primarily hide messages inside benign files. Therefore, the described "hiding the existence of the message itself" corresponds toSteganography (C).


45. Frage
David, a cybercriminal, targeted a community and initiated anti-social campaigns online. In this process, he used a layer of the web that allowed him to maintain anonymity during the campaign.
Which of the following layers of the web allowed David to hide his presence during the anti-social campaign?

Antwort: D

Begründung:
The layer of the web most associated withmaintaining anonymityfor users and services is theDark Web. In digital forensics terminology, the Dark Web refers to services hosted on overlay networks (such as Tor hidden services) that arenot indexed by standard search enginesand are typically accessible only through specialized software and configurations. Its core characteristic is that it is deliberately designed to reduce traceability by routing traffic through multiple relays and separating identifying information (like the user's real IP address) from the destination. This makes attribution and geolocation significantly harder using traditional network logs alone, which is why adversaries often choose it to conduct covert communications, host content, or coordinate campaigns.
By contrast, theSurface Web(the regular, indexed portion of the web) is generally reachable through normal browsers and is easier to monitor and attribute using conventional ISP, server, and platform logs. "World Wide Web" is a general term for web content accessed via HTTP/HTTPS and does not specifically imply anonymity. TheDeep Webrefers to content not indexed by search engines (e.g., webmail, databases, authenticated portals), but it is not inherently anonymizing-many deep web resources are simply private or access-controlled. Therefore, the layer enabling David to hide his presence is theDark Web (C).


46. Frage
Sandra, a hacker, targeted Johana, a software professional, to steal her banking details. She started sending frequent, random pop-up messages with malicious links to her social media page. Johana accidentally clicked on a link, causing a malicious program to get installed in her system. Subsequently, when Johana attempted to access her banking website, the URL redirected her to a malicious website controlled by Sandra. Johana entered her banking credentials on the fake website, which Sandra then captured.
Identify the type of attack performed by Sandra on Johana.

Antwort: C

Begründung:
The scenario describes a victim beingredirected from a legitimate banking URL to a fraudulent websitewithout intending to visit it, after malware is installed on the system. This behavior is characteristic ofpharming, an attack in which an adversarycauses redirectionto a malicious destination even when the user types the correct address or clicks a legitimate bookmark. In digital forensics references, pharming is commonly achieved by manipulatingname resolution or routing mechanisms, such as altering the localhosts file, changingDNS server settings, poisoning DNS responses, modifying browser proxy settings, or installing malware that intercepts and rewrites web requests. The key forensic indicator is that the victim's request for the real domain is transparently diverted to attacker-controlled infrastructure, where credentials are harvested through a convincing spoofed login page.
The other options do not match the redirection-and-fake-site mechanism.Tailgatingis physical access abuse (following someone into a secure area).Dumpster divinginvolves retrieving sensitive information from discarded materials.Shoulder surfingis observing credentials by watching the victim type. Because the essential action here ismalicious redirection to a fake site to steal credentials, the correct answer isPharming (A).


47. Frage
While investigating a web attack on a Windows-based server, Jessy executed the following command on her system:
C:> net view <\10.10.10.11>
What was Jessy's objective in running the above command?

Antwort: A

Begründung:
The Windowsnet view \\<computer>command is used to enumerateshared resources(SMB shares) that a remote Windows system is publishing. When Jessy runsnet view \\10.10.10.11, her goal is to retrieve a list of the target host's visible shares-such as administrative shares (e.g.,C$,ADMIN$) and any custom shares created for departments, applications, or users. In forensic and incident-response practice, this is important because attackers commonly use SMB shares forlateral movement,staging tools,dropping payloads, andexfiltrating data. By reviewing the shares exposed by a suspected server, the investigator can quickly identify unexpected or overly permissive shares, locate potential repositories of web content or logs, and determine whether a compromised web server is also exposing file resources that expand the attacker's options.
The other options map to different commands and artifacts: disk space usage is checked with storage utilities (notnet view), open sessions are examined with commands likenet session, and identifying users accessing files typically involvesnet fileor server auditing logs. Therefore, Jessy's objective was toreview file shareson the remote host.


48. Frage
Jack, a forensic investigator, was appointed by an organization to perform a security audit on a Linux system.
In this process, Jack collected information about the present status of the system and listed all the applications running on various ports to detect malicious programs.
Which of the following commands can help Jack determine any programs/processes associated with open ports?

Antwort: C

Begründung:
On Linux, a key step in a forensic triage or security audit is mappingopen/listening portsto theowning processso investigators can identify suspicious services (backdoors, unauthorized daemons, rogue remote- access tools) and correlate them with binaries, users, startup mechanisms, and timestamps. The command netstat -tulpnis designed for exactly this purpose. In this switch set:-tlimits output to TCP sockets,-uincludes UDP sockets,-lshows only listening sockets (open ports awaiting connections),-pdisplays the owningprocess name and PID, and-nprevents name resolution by showing numeric IP addresses and ports (faster and avoids altering evidence via DNS queries). This combination yields a concise list of active listening ports and the processes bound to them, which is highly valuable for detecting unexpected services and attributing network exposure to a specific executable.
The other options do not provide process-to-port attribution:netstat -ishows interface statistics,ip rshows the routing table, andnetstat -rndisplays the routing table in numeric form. Therefore, the correct command is netstat -tulpn(D).
