A helpdesk technician is reviewing several recent security incident logs across the organization. Match each reported security incident scenario on the left to its corresponding threat type on the right.
- An employee receives a text message on their mobile phone claiming their financial account is compromised, containing a shortened link to verify credentials.Smishing
- A system administrator discovers hidden software that altered kernel-level system files to conceal unauthorized backdoor access from Task Manager.Rootkit
- An unbadged visitor carrying a large package follows an employee closely through a secure door immediately after the employee scans their access card.Tailgating
- A user reports that all local files have been encrypted with an unrecognized extension and a text file demands cryptocurrency payment to unlock them.Ransomware
Answer
Smishing matches the SMS text message lure scenario; Rootkit matches the kernel-level process hiding scenario; Tailgating matches the physical intrusion following an authorized employee scenario; Ransomware matches the file encryption demanding payment scenario.
Each scenario represents a classic security threat vector: SMS-based phishing is smishing, kernel-level hiding malware is a rootkit, following someone through a secure door without authentication is tailgating, and encrypting files for extortion is ransomware.
