Attackers Log In Instead of Breaking In
Traditionally, cybersecurity has focused on firewall penetration, malware, network exploits, and system vulnerabilities that allow attackers access. Any comprehensive security program must still defend against those threats.
Modern attacks, however, increasingly target identity rather than infrastructure. Deepfakes, phishing, and spear phishing campaigns focus on stealing who you are in order to gain access to systems. According to the Verizon 2025 Data Breach Investigations Report, 88 percent of breach incidents involved stolen credentials, which represents a significant increase from prior years.
Artificial Intelligence and Identity Theft
Artificial intelligence is accelerating this trend. AI makes it faster, cheaper, and far more convincing to impersonate individuals and steal login credentials. As part of Theorem’s 2025 cybersecurity penetration testing program, we worked with external ethical hackers who created a convincing executive deepfake and attempted live social engineering calls. The attack failed, not because of a technical control, but because of employee judgment and awareness.
AI-driven social engineering exploits trust rather than software vulnerabilities. As a result, modern security practices must treat identity as a primary risk control, not as an IT afterthought.
Theorem’s Security Approach
For our 2026 application rollout, we use Microsoft Azure AD B2C to manage user authentication. This allows us to rely on an enterprise-grade identity platform that continuously evolves alongside modern threats while we remain focused on delivering a secure and reliable product to our clients.
Protecting customer data remains Theorem’s top priority. Our 2025 independent penetration testing program resulted in zero high-risk findings and confirmed strong platform resilience. In addition, our auditors found that our employees were educated and aware of proper practices to prevent credential theft and other social engineering scams. Independent attestation documentation is available upon request.
What Comes Next: Strengthening Identity Security With Mandatory MFA
Security at Theorem is an ongoing discipline built on independent validation, layered controls, and continuous improvement. As threats evolve, so do our defenses. In 2026, we will introduce mandatory multi-factor authentication (MFA) for all users, utilizing authenticator applications rather than SMS or email verification to ensure the highest standard of identity protection.
We will provide rollout timing, onboarding materials, and client support resources shortly. Fill out the form below to be kept in the know.
