B. The process is necessarily fabricated because pool scans cannot identify real processes
C. The process must be a normal service because its thread references remain valid
D. The process may be terminated or hidden through direct kernel object manipulation

50 Which combination most strongly supports code injection into a user process rather than ordinary loading of a DLL?

A. The Cookies database, Local State key, and applicable user DPAPI key material
B. Only the Cookies database and the browser's public code-signing certificate
C. The DNS resolver cache and the system's machine account password hash alone
D. Only the browser cache because cached responses contain every cookie in plaintext

55 An NTFS file has a recent $STANDARD_INFORMATION modification time but an older $FILE_NAME modification time. Other evidence suggests timestomping. Which interpretation is most accurate?

B. The mismatch alone proves malicious timestamp alteration beyond reasonable dispute
C. The $STANDARD_INFORMATION timestamp cannot be changed by user-mode programs
D. The $FILE_NAME timestamp always records the file's latest content modification

56 A suspect file's unnamed NTFS $DATA stream hashes to a known benign utility, but its allocated size is larger than expected and execution artifacts reference utility.exe:run. What should be examined next?

A. The volume label because it records alternate-stream execution commands
B. Only the file's DOS short name stored in the parent directory
C. Named $DATA attributes associated with the same file record
D. Only unallocated clusters located before the file's first extent

A. Every record before the directive will automatically receive a new timestamp
B. The web server recalculates earlier records whenever the field order changes
C. Later values may be assigned to incorrect fields and produce false correlations
D. The directive causes NTFS to encrypt all subsequent log records with EFS

58 A Windows application log is UTF-16LE with a byte-order mark. A byte-oriented ASCII search reports no occurrences of a known command that is visibly present in a text editor. What is the sound response?

Text-based Logs Hard

B. Security event 4634 with Logon Type 2 and a local loopback address
C. Security event 4624 with Logon Type 3 and no terminal-services correlation
D. System event 7045 with an installed service and no user-logon identifier

60 A local Security EVTX file begins at record ID 9000, while an earlier backup ends at record ID 7000. There is no local event 1102. Which conclusion is most defensible?

Windows Event Logs Hard
A. Exactly 1,999 records were maliciously deleted from the middle of the live file
B. The gap alone is inconclusive because rollover, replacement, or clearing may explain it
C. The record IDs prove that Windows generated no security events during the interval
D. The absence of event 1102 proves that the Security log was never cleared or replaced
