YES Bank

Yes Bank is an Indian private sector bank that offers a range of financial products and services to retail, corporate, and institutional customers. Its core activities include accepting deposits, providing loans and credit facilities, offering treasury and wealth management solutions, and facilitating payments and settlements. The bank serves individuals, small and medium enterprises, large corporations, and government entities across various regions of India. It operates through a network of branches, ATMs, and digital channels that enable customers to access banking services remotely. As a scheduled commercial bank, it is regulated by the Reserve Bank of India and adheres to the banking laws and guidelines applicable in the country.

The organisation’s reliance on digital infrastructure was highlighted during a 2020 DDoS extortion campaign in which attackers targeted its backend systems, API endpoints, and DNS servers with peak traffic of approximately 200 Gbps, seeking Bitcoin payments to halt the disruption. This incident underscored the bank’s dependence on resilient online platforms for delivering services to its clients. In 2016, Yes Bank was affected by a malware intrusion at Hitachi Payment Services that compromised roughly 3.2 million debit cards issued by several banks, including its own, leading to unauthorized transactions on Visa and MasterCard networks primarily in China. The breach prompted the bank to advise affected customers to change their PINs, use its own ATMs, and monitor accounts for suspicious activity. These events illustrate the bank’s exposure to third‑party payment processors and the importance it places on securing both internal systems and external partnerships. Yes Bank remains headquartered in India and continues to operate as a distinct legal entity within the Indian banking sector.
