Shuman Ghosemajumder: A Pioneer in Cybersecurity

Shuman Ghosemajumder, the Co-Founder and CEO of Reken, brings decades of experience in cybersecurity and trust, having led groundbreaking efforts at Google and Shape Security. At Google, Shuman was instrumental in developing machine learning models to combat fraud on a massive scale. His work at Shape Security further refined his expertise in identifying and mitigating sophisticated cyber threats, particularly those targeting industries like banking and aviation.

The Role of Generative AI in Cybersecurity

Generative AI is revolutionizing both the attack and defense landscapes in cybersecurity. Shuman elaborates on how cybercriminals leverage AI to launch sophisticated, large-scale fraud schemes. Using AI, they can simulate natural language, voice, and even human interactions—making traditional defenses less effective. On the flip side, AI holds promise for bolstering defense mechanisms, enabling companies to automate Security Operations Center (SOC) tasks, identify vulnerabilities, and respond more efficiently to incidents.

Medium- and Long-Term Cybersecurity Threats

The conversation also delved into the evolving nature of cyber threats. In the medium term, the focus remains on combating relatively straightforward yet highly effective techniques, such as credential stuffing and botnet-enabled fraud. Long-term challenges, however, center around generative AI's potential to seamlessly mimic human behavior, blurring the lines between human and machine interactions.

AI Misconceptions in Business

Shuman highlights a common pitfall: conflating current generative AI capabilities with artificial general intelligence (AGI). While generative AI excels at simulating human-like responses and improving productivity in tasks like customer support, it is far from the omnipotent AI of science fiction. This misunderstanding often leads to unrealistic expectations and disappointment, particularly in areas where AI's limitations, such as hallucinations and context errors, become apparent.

Reken: Tackling the Final Frontier

Shuman’s company, Reken, aims to counter the growing threats posed by generative AI-driven cybercrime. Set to formally launch in 2025, Reken will specialize in protecting against increasingly sophisticated fraud schemes that exploit AI. Shuman draws parallels to classic sci-fi scenarios where distinguishing between humans and robots becomes a daunting challenge—a reality already manifesting in today’s online interactions.
