Use of LinkedIn

The exploitation of the professional networking platform reveals the adaptability and resourcefulness of cybercriminals in leveraging popular online platforms for their malicious activities. In the case of the DUCKTAIL malware campaign, LinkedIn serves as a scouting and phishing platform for the threat actors. They utilize LinkedIn to identify potential targets, specifically individuals in managerial, digital marketing, digital media, and human resources roles. By targeting professionals with high-level account access, preferably with Admin privileges, the threat actors aim to maximize their impact and increase their chances of success while remaining undetected. This highlights the need for robust security measures on LinkedIn to protect users from phishing techniques employed by cybercriminals. Professionals should exercise caution and be aware of the risks posed by phishing attacks on the platform, and LinkedIn should continue to enhance its security measures to mitigate these threats.
