2. Understanding Digital Banking Risks

  • What do you perceive as the biggest cybersecurity threats facing digital banking today? Could you provide some real-world examples where these risks have had a significant impact?

One of the biggest cybersecurity threats facing digital banking today is the rise of sophisticated phishing and social engineering attacks. Attackers are increasingly targeting customers to steal credentials and gain unauthorized access to accounts. Additionally, insider threats and weak third-party security postures is also a major risk, particularly as banks depend on a variety of vendors and cloud services.

In addition to that we cannot neglect the surge of ransomware attacks on financial institutions. In these cases, attackers not only encrypt the banks’ systems but also threaten to leak sensitive customer sensitive information unless a ransom is paid. Another major issue is advanced persistent threats, where attackers gain access for any critical system and remain undetected for long periods which may cause extensive damage.

An example is the Bangladesh Bank heist in 2016, where hackers exploited weak security protocols in the SWIFT system, resulting in the theft of $81 million. This incident highlighted the need for robust security measures at every layer of digital banking infrastructure.
