Multi-Year Phishing Campaign Compromises Over 500 Organizations

A sustained phishing operation has breached more than 500 entities across aviation, energy, logistics, and critical infrastructure over several years.

A prolonged phishing campaign has successfully compromised over 500 organizations spanning multiple high-value sectors, according to SecurityWeek reporting.
