A help desk technician is responding to a ticket where a workstation web browser continuously opens pop-up advertisements and redirects to unauthorized search engines. Place the following remediation steps in the correct chronological order from first to last to resolve the browser hijacking issue.
- 1Disconnect the workstation from the network to isolate the system.
- 2Remove unrecognized browser extensions and reset the browser to default settings.
- 3Run a full anti-malware scan using updated virus definitions.
- 4Reconnect the workstation to the network and verify web browser functionality.
Answer
The proper sequence to troubleshoot and remediate browser redirects and pop-ups is: 1) Disconnect the workstation from the network to isolate the system, 2) Remove unrecognized browser extensions and reset the browser to default settings, 3) Run a full anti-malware scan using updated virus definitions, and 4) Reconnect the workstation to the network and verify web browser functionality.
The standard incident response procedure requires isolating the system first to stop malware traffic, cleaning browser configurations and running anti-malware scans to eliminate persistent threats, and finally reconnecting the device to verify normal operation.
