Punjab National Bank (PNB) is increasing its cybersecurity investment, citing growing security risks associated with the use of AI models. According to reports, the third-largest state-run lender by market capitalisation earmarks about 20% of its technology budget for cybersecurity. The bank’s planned spend is estimated at roughly ₹700 crore to ₹800 crore. The move is framed around concerns that AI systems—including models referenced in reporting such as Anthropic’s Mythos—can introduce new threat vectors, raising the need for stronger safeguards. The reports describe the increase as part of PNB’s broader technology and risk management efforts, with cybersecurity receiving a larger share of its IT resources. While details on specific measures are not outlined across the available summaries, the agreed focus is on strengthening cyber defences as banks adopt or plan to engage with AI capabilities. The information presented does not indicate immediate incidents or breaches, but it describes a proactive shift in funding priorities tied to emerging AI security concerns.
