A single successful phishing email can give attackers access to privileged accounts, remote management tools, customer environments, and sensitive business data. Once inside, they can launch business email compromise attacks, send phishing emails from legitimate accounts, impersonate employees or vendors, and target customers from trusted domains. If a phishing email tricks an employee into revealing their login credentials, attackers can use those privileges to access critical systems, steal sensitive data, deploy ransomware, and move across multiple client environments.
