Phishing, Office 365 and the Commercialization of Cybercrime

Cybercriminals have professionalized their operations, applying business principles like supply chains, bulk discounts, and outsourcing to phishing attacks targeting Office 365 credentials. Dark web marketplaces sell fake O365 login pages for $150, bulk phishing templates, and stolen credentials at $2 each. Specialized roles have emerged: some hackers build phishing kits, others harvest credentials, and others buy them wholesale to exploit compromised accounts. The ecosystem even has its own dispute resolution forums when transactions go wrong. Early detection and rapid response are key defenses against these increasingly commercialized threats.
