Unit 42 of Palo Alto Networks uncovered a sophisticated phishing campaign targeting European companies' Azure cloud environments, affecting approximately 20,000 employees across various sectors.
The hackers employed a multi-step approach, using malicious DocuSign files and social engineering tactics to extract login credentials, gaining unauthorized entry into corporate cloud infrastructures.
Through constant logins with stolen credentials, the attackers aimed to maintain a long-term presence in sensitive Azure environments, posing significant risks to companies' data and security.
Despite successfully targeting numerous employees, prompt intervention prevented hackers from completing potentially disastrous actions, highlighting critical vulnerabilities that organizations must address in their cybersecurity measures.
