Zorluk: ZorMalware Detection, Removal, and Prevention

A helpdesk technician is responding to an incident involving a Windows workstation infected with a persistent crypto-mining Trojan. The malware infection has already been identified and verified by security logs. Place the following remediation actions in the correct sequence according to the official CompTIA 7-step malware removal process.

  1. 1Disconnect the computer from both the wired and wireless networks to isolate the machine.
  2. 2Disable System Restore in Windows to purge existing restore points containing infected files.
  3. 3Update anti-malware definition signatures and run a comprehensive system scan in Safe Mode.
  4. 4Re-enable System Restore and construct a new, clean system restore point.
  5. 5Conduct security awareness training with the workstation user regarding safe browsing and download habits.

Cevap

The correct chronological sequence following the CompTIA 7-step malware removal methodology is: 1) Disconnect the computer from networks (Quarantine), 2) Disable System Restore, 3) Update anti-malware signatures and scan in Safe Mode (Remediate), 4) Re-enable System Restore and create a clean restore point, and 5) Educate the end user.
The standard CompTIA 7-step malware removal process follows a specific lifecycle: 1. Identify malware symptoms, 2. Quarantine infected systems, 3. Disable System Restore, 4. Remediate infected systems (a. Update anti-malware software, b. Scan and use removal techniques), 5. Schedule updates and enable automated scans, 6. Enable System Restore and create a restore point, 7. Educate the end user. Arranging the actions from isolation (quarantine) through disabling System Restore, updating/scanning, re-enabling System Restore, and finishing with user training strictly satisfies this workflow.

Adım Adım Çözüm

1
Isolate the compromised system (Quarantine)
Network communication is severed, preventing malware proliferation.
CompTIA Step 2 dictates quarantining the infected system immediately after identification.
2
Disable System Restore
Corrupted restore points containing infected system files are deleted.
CompTIA Step 3 requires disabling System Restore prior to scanning so malware cannot survive via system rollbacks.
3
Remediate infected system
Anti-malware signatures are updated and the crypto-mining Trojan is identified and deleted in Safe Mode.
CompTIA Step 4 specifies updating anti-malware engine definitions and using scan/removal tools.
4
Re-enable System Restore and create a restore point
A clean recovery baseline is established after ensuring the system is clean and scheduled updates are set.
CompTIA Step 6 restores system protection functionality once remediation is successful.
5
Educate the end user
The end user learns preventative practices to lower the risk of reinfection.
CompTIA Step 7 concludes the remediation lifecycle with end-user security training.
