Question

Difficulty: MediumSocial Engineering Attacks and Vectors

A security analyst is investigating a dual-vector social engineering campaign targeting a corporate facility. During the investigation, the analyst notes that employees received text messages prompting them to verify credentials on a spoofed portal, while physical USB flash drives labeled "Executive Salaries" were strategically dropped in the employee parking area. Which of the following social engineering attack vectors were executed during this campaign? (Select TWO.)

  1. Smishing by delivering malicious web links through cellular text messagingAnswer
  2. Baiting by leaving physical storage media loaded with malware in accessible areasAnswer
  3. C
    Vishing by placing voice phone calls to trick personnel into granting remote access
  4. D
    Watering hole attacks by compromising legitimate websites frequented by company staff

Answer

The attack vectors executed in this campaign are smishing (using cellular text messages with malicious links) and baiting (strategically dropping infected physical media to exploit curiosity).
Smishing refers specifically to phishing attacks conducted over Short Message Service (SMS) text messages. Baiting involves leaving physical media, such as flash drives, in locations where victims will pick them up out of curiosity. Both mechanisms match the attack vectors described in the scenario.

Step-by-Step Solution

1
Analyze the first incident indicator in the scenario.
Employees received SMS text messages containing links to a spoofed credential portal.
Phishing conducted via SMS text messaging is classified as smishing.
2
Analyze the second incident indicator in the scenario.
Malicious USB drives labeled with enticing titles were left in the parking area for employees to find.
Promising a tangible item or relying on curiosity via physical media drops is classified as baiting.
3
Correlate identified vectors with the options.
Smishing and baiting correctly match the scenario indicators.
Both vectors directly align with the delivery mechanisms described in the incident report.
