Zorluk: Çok zorMalware Types and Indicators of Compromise

Match each technical host telemetry artifact and indicator of compromise with its corresponding malware classification.

  • Kernel callback object modification paired with active process unlinking via Direct Kernel Object Manipulation (DKOM) in kernel memory structures.Kernel-level Rootkit
  • Persistent WMI event subscription executing an obfuscated PowerShell payload directly in RAM via reflective DLL injection without writing binary files to disk.Fileless Malware
  • System process executing commands to disable volume shadow copies while recursively encrypting specific file headers using AES-GCM algorithms.Ransomware
  • Dormant code segment embedded in a legitimate application that monitors Active Directory domain controller time and executes a destructive payload upon reaching a specified date.Logic / Time Bomb

Cevap

Kernel memory modification via DKOM matches Kernel-level Rootkit; WMI persistent memory injection matches Fileless Malware; cryptographic file encryption and shadow copy deletion match Ransomware; condition-triggered dormant execution matches Logic / Time Bomb.
Each malware classification is accurately paired with its distinct technical operational footprint: kernel rootkits modify core OS memory structures via Ring 0 privileges; fileless malware executes in RAM without traditional disk artifacts; ransomware inhibits host recovery while encrypting data storage; and logic/time bombs depend on specific environmental triggers.

Adım Adım Çözüm

1
Analyze the telemetry artifact describing kernel memory manipulation and hidden execution pathways.
Identified DKOM and kernel callbacks operating in Ring 0 context.
Rootkits at the kernel layer modify OS data structures to evade detection.
2
Analyze the telemetry artifact referencing non-disk execution mechanisms.
Identified WMI persistence and reflective RAM injection.
Fileless malware relies on living-off-the-land techniques and memory resident code execution.
3
Evaluate indicators of data unavailability combined with recovery inhibitor commands.
Identified AES-GCM encryption paired with volume shadow copy purge.
Ransomware actively prevents recovery while denying access to user data.
4
Evaluate the trigger-based execution criteria.
Identified date-based execution criteria within dormant host code.
Logic and time bombs require specified pre-conditions before detonating.
