Question 350
A local Windows Security log was cleared before forensic capture. Which event can help identify that action?
- Event 1102
- Sysmon Event 3
- Event 4624
- PowerShell 4104
Explanation
Correct Answer
A:Event 1102 records clearing of the Security audit log and may include the subject account. External log forwarding helps preserve surrounding context if local history is missing.
Incorrect Answers
B:The current inquiry asks about clearing of the Windows Security log; Sysmon Event ID 3 describes network connections associated with processes when configured; this mechanism chiefly addresses Sysmon process-to-network connection association. It provides host attribution but no complete application payload; it cannot prove clearing of the Windows Security log on its own.
C:In an inquiry concerning a Windows successful logon record, security event 4624 records successful logons when audited, with logon type and account context; the scope does not extend to clearing of the Windows Security log. It does not by itself show which commands the session performed; that issue cannot settle clearing of the Windows Security log.
D:Even though the scenario needs clearing of the Windows Security log, PowerShell event 4104 can record executed script block text, with coverage depending on policy and execution context; the action relates to logged PowerShell script content. It can reveal behavior not evident from a process name alone; this remains insufficient for clearing of the Windows Security log.
Question 351
An intruder may have installed a new Windows service for persistence. Which System log event often records the installation?
- Sysmon Event 3
- Event 7045
- Event 4688
- Event 4625
Explanation
Correct Answer
B:Service Control Manager event 7045 can document creation of a service with associated properties. Investigators should correlate it with executable and privilege evidence.
Incorrect Answers
A:With installation of a Windows service as the investigative issue, Sysmon Event ID 3 describes network connections associated with processes when configured; the result would concern Sysmon process-to-network connection association. It provides host attribution but no complete application payload; this would not resolve installation of a Windows service.
C:The stem asks about installation of a Windows service; event 4688 records process creation under appropriate audit settings; command-line inclusion requires its own policy configuration; the described operation is used for Windows audited process creation. Execution evidence depends on what was enabled at the time; a determination about installation of a Windows service requires other support.
D:Instead of a method addressing installation of a Windows service, event 4625 represents failed logon attempts where auditing provides the event; this one concerns a Windows failed logon record. Status and substatus fields may help distinguish causes and logon paths; it cannot independently determine installation of a Windows service.
Question 352
A task appears to have been created just before suspicious code execution, and Security task auditing is enabled. Which ID is relevant?
- Event 4698
- Event 4624
- Event 1102
- Event 7045
Explanation
Correct Answer
A:Security event 4698 records scheduled task creation when appropriate auditing is enabled. Other Task Scheduler Operational events can offer complementary lifecycle evidence.
Incorrect Answers
B:For an analysis centered on a Windows successful logon record, security event 4624 records successful logons when audited, with logon type and account context; the present need is creation of a Windows scheduled task. It does not by itself show which commands the session performed; a different finding about creation of a Windows scheduled task is still needed.
C:When the investigative task is clearing of the Windows Security log, event 1102 records clearing of the Security audit log and may include the subject account; that differs from the question about creation of a Windows scheduled task. External log forwarding helps preserve surrounding context if local history is missing; that leaves creation of a Windows scheduled task unresolved.
D:The current inquiry asks about creation of a Windows scheduled task; service Control Manager event 7045 can document creation of a service with associated properties; this mechanism chiefly addresses installation of a Windows service. Investigators should correlate it with executable and privilege evidence; it cannot prove creation of a Windows scheduled task on its own.
Question 353
Endpoint telemetry contains Sysmon events and investigators need command line, hashes and process lineage for a launch. Which ID should they inspect?
- Event 4672
- Event 4624
- Sysmon Event 3
- Sysmon Event 1
Explanation
Correct Answer
D:Sysmon Event ID 1 captures process creation with enriched context when Sysmon is installed and configured. It is distinct from Windows native Security 4688.
Incorrect Answers
A:The objective here is Sysmon process creation details; security event 4672 indicates special privileges assigned to a new logon under audit; the option would instead inform special privileges assigned at logon. It is not itself evidence that each privilege was exercised; it is not direct evidence of Sysmon process creation details.
B:For a separate investigation of a Windows successful logon record, security event 4624 records successful logons when audited, with logon type and account context; that is not the determination of Sysmon process creation details in the stem. It does not by itself show which commands the session performed; the evidence still must speak to Sysmon process creation details.
C:With Sysmon process creation details as the investigative issue, Sysmon Event ID 3 describes network connections associated with processes when configured; the result would concern Sysmon process-to-network connection association. It provides host attribution but no complete application payload; this would not resolve Sysmon process creation details.
Question 354
A suspicious process initiates an outbound TCP connection, and Sysmon network connection monitoring is enabled. Which event is relevant?
- Sysmon Event 1
- PowerShell 4104
- Sysmon Event 3
- Event 4625
Explanation
Correct Answer
C:Sysmon Event ID 3 describes network connections associated with processes when configured. It provides host attribution but no complete application payload.
Incorrect Answers
A:A case involving Sysmon process creation details might use this approach: Sysmon Event ID 1 captures process creation with enriched context when Sysmon is installed and configured; the required result here is Sysmon process-to-network connection association. It is distinct from Windows native Security 4688; it cannot replace proof about Sysmon process-to-network connection association.
B:The required finding is about Sysmon process-to-network connection association; PowerShell event 4104 can record executed script block text, with coverage depending on policy and execution context; this addresses the separate concern of logged PowerShell script content. It can reveal behavior not evident from a process name alone; it does not by itself answer Sysmon process-to-network connection association.
D:For an analysis centered on a Windows failed logon record, event 4625 represents failed logon attempts where auditing provides the event; the present need is Sysmon process-to-network connection association. Status and substatus fields may help distinguish causes and logon paths; a different finding about Sysmon process-to-network connection association is still needed.
Question 355
Investigators need script block content from PowerShell when script block logging has been enabled. Which event ID helps?
- Sysmon Event 1
- Sysmon Event 3
- Event 7045
- PowerShell 4104
Explanation
Correct Answer
D:PowerShell event 4104 can record executed script block text, with coverage depending on policy and execution context. It can reveal behavior not evident from a process name alone.
Incorrect Answers
A:Even though the scenario needs logged PowerShell script content, Sysmon Event ID 1 captures process creation with enriched context when Sysmon is installed and configured; the action relates to Sysmon process creation details. It is distinct from Windows native Security 4688; this remains insufficient for logged PowerShell script content.
B:For the separate question of Sysmon process-to-network connection association, Sysmon Event ID 3 describes network connections associated with processes when configured; the requested assessment of logged PowerShell script content remains open. It provides host attribution but no complete application payload; there is no direct finding about logged PowerShell script content.
C:The objective here is logged PowerShell script content; service Control Manager event 7045 can document creation of a service with associated properties; the option would instead inform installation of a Windows service. Investigators should correlate it with executable and privilege evidence; it is not direct evidence of logged PowerShell script content.
Question 356
A memory image shows a running process that is absent from normal API enumeration. Which comparison technique can expose hidden processes?
- Credential material in RAM
- Process list comparison
- Process hollowing detection
- DLL injection investigation
- Memory string extraction
Explanation
Correct Answer
B:Compare multiple process enumeration methods, including pool scanning and linked-list views, to identify discrepancies. Stale memory objects can resemble hidden processes and need validation.
Incorrect Answers
A:Instead of a method addressing processes concealed from ordinary enumeration, authentication process memory can contain sensitive derived secrets or tokens, depending on protections and state; this one concerns possible credential exposure in process memory. Access and analysis should be limited and carefully safeguarded; it cannot independently determine processes concealed from ordinary enumeration.
C:A case involving a legitimate process image replaced in memory might use this approach: process hollowing replaces or manipulates the code image of a launched process, making its name misleading; the required result here is processes concealed from ordinary enumeration. Compare mapped memory with expected image and process creation artifacts; it cannot replace proof about processes concealed from ordinary enumeration.
D:The required finding is about processes concealed from ordinary enumeration; module enumeration and injection indicators can reveal foreign libraries loaded into a target process; this addresses the separate concern of unusual libraries loaded into another process. Library path alone is insufficient; corroborate memory mappings and execution evidence; it does not by itself answer processes concealed from ordinary enumeration.
E:Although the case asks about processes concealed from ordinary enumeration, string and structured-memory searches can locate runtime configuration, domains and decoded content; the action instead concerns decoded runtime content in RAM. Results require process and offset context to avoid false associations; it does not establish processes concealed from ordinary enumeration.
Question 357
A legitimate process contains private executable memory regions without a corresponding mapped image. Which memory analysis focus is relevant?
- Kernel driver investigation
- Credential material in RAM
- Injected-code VAD review
- DLL injection investigation
Explanation
Correct Answer
C:Virtual address descriptor and memory-region inspection can reveal suspicious executable allocations or injection. Benign JIT engines also create executable private memory, requiring context.
Incorrect Answers
A:The current inquiry asks about unexpected executable memory inside a process; kernel module and driver object enumeration can expose loaded components and inconsistencies; this mechanism chiefly addresses loaded kernel-level code and driver objects. Signed status alone is not conclusive proof of benign behavior; it cannot prove unexpected executable memory inside a process on its own.
B:In an inquiry concerning possible credential exposure in process memory, authentication process memory can contain sensitive derived secrets or tokens, depending on protections and state; the scope does not extend to unexpected executable memory inside a process. Access and analysis should be limited and carefully safeguarded; that issue cannot settle unexpected executable memory inside a process.
D:For the separate question of unusual libraries loaded into another process, module enumeration and injection indicators can reveal foreign libraries loaded into a target process; the requested assessment of unexpected executable memory inside a process remains open. Library path alone is insufficient; corroborate memory mappings and execution evidence; there is no direct finding about unexpected executable memory inside a process.
Question 358
An implant's configuration is absent from the disk binary but appears in decrypted process memory. Which analysis technique can find it?
- Memory network socket analysis
- DLL injection investigation
- Memory string extraction
- Memory acquisition side effects
Explanation
Correct Answer
C:String and structured-memory searches can locate runtime configuration, domains and decoded content. Results require process and offset context to avoid false associations.
Incorrect Answers
A:For questions about network socket artifacts recoverable from RAM, memory parsing can recover active or residual network endpoint structures and owning processes; that differs from decoded runtime content in RAM. Stale objects and capture timing require careful interpretation; it provides no direct answer to decoded runtime content in RAM.
B:The stem asks about decoded runtime content in RAM; module enumeration and injection indicators can reveal foreign libraries loaded into a target process; the described operation is used for unusual libraries loaded into another process. Library path alone is insufficient; corroborate memory mappings and execution evidence; a determination about decoded runtime content in RAM requires other support.
D:In work concerning the non-atomic nature of live memory capture, live capture changes the system, consumes memory and produces a time-skewed snapshot rather than an atomic freeze; the operation would not resolve decoded runtime content in RAM. Document tool actions and acquisition timing when interpreting RAM; the distinction leaves decoded runtime content in RAM unsettled.
Question 359
A user process has a loaded library from an unusual user-writable path after suspicious remote-thread activity. Which memory investigation applies?
- Memory image profile identification
- DLL injection investigation
- Memory string extraction
- Process list comparison
Explanation
Correct Answer
B:Module enumeration and injection indicators can reveal foreign libraries loaded into a target process. Library path alone is insufficient; corroborate memory mappings and execution evidence.
Incorrect Answers
A:For an analysis centered on correct structure symbols for a captured operating system, memory analysis depends on appropriate kernel structure definitions and symbol information matching the captured OS; the present need is unusual libraries loaded into another process. Incorrect mappings can produce fabricated object offsets; a different finding about unusual libraries loaded into another process is still needed.
C:The current inquiry asks about unusual libraries loaded into another process; string and structured-memory searches can locate runtime configuration, domains and decoded content; this mechanism chiefly addresses decoded runtime content in RAM. Results require process and offset context to avoid false associations; it cannot prove unusual libraries loaded into another process on its own.
D:In an inquiry concerning processes concealed from ordinary enumeration, compare multiple process enumeration methods, including pool scanning and linked-list views, to identify discrepancies; the scope does not extend to unusual libraries loaded into another process. Stale memory objects can resemble hidden processes and need validation; that issue cannot settle unusual libraries loaded into another process.
Question 360
The team suspects credentials were exposed by a memory dump of the authentication subsystem. Which analytical concern is central?
- Memory acquisition side effects
- Credential material in RAM
- Memory network socket analysis
- Process hollowing detection
- Injected-code VAD review
Explanation
Correct Answer
B:Authentication process memory can contain sensitive derived secrets or tokens, depending on protections and state. Access and analysis should be limited and carefully safeguarded.
