Phishing Campaign Exploits Brand Impersonation and LinkedIn Data

Threat actors successfully targeted senior professionals by impersonating Palo Alto Networks staff and using scraped LinkedIn data to craft convincing phishing messages. The attackers exploited both brand trust and professional insecurities by claiming resumes failed system filters and requesting fees for alignment services.
