As long as there have been banks, there have been bank robbers. In the past, bank robbers may have held up bank tellers at gunpoint. Today, threats are less visible—but just as frightening. This weekend’s massive ransomware attack demonstrated just how pervasive, far-reaching, and devastating a cyberattack can be.

What is ransomware?

Even if you hadn’t heard the word “ransomware” before, after this weekend, you’re probably talking about it quite a bit (or at least reading about it). On Friday, a global ransomware attack hit thousands of computer systems—and is being called “the biggest cyberattack the world has ever seen.” Organizations such as the UK’s National Health Service (NHS) and global companies like FedEx were affected by the ransomware strain, known as WannaCry.

Ransomware is a type of malware that encrypts data, making it impossible for the owners of that data to access it unless they pay a fee. In this case, the WannaCry virus spread through a vulnerability in Microsoft Windows software. Although the “hole” in the software that allowed the virus into the system could have been patched by a free upgrade from Microsoft in April, many computers that were infected were out-of-date devices that were likely not deemed worth the cost of an upgrade. Some were machines involved in functions that were too difficult to take offline to patch without disrupting crucial operations. This ransomware virus was unique because it spread independently through networks to unpatched devices, without the need for a person to download a file or visit a website.

Cybercrime and financial services: Not a new relationship

 Though this week’s WannaCry attack was one of the most visible and widespread cyberattacks, it wasn’t the first, and it won’t be the last. The 2016 Cybercrime Report from Cybersecurity Ventures predicts cybercrime will cost the world in excess of $6 trillion annually by 2021, making it more profitable than the global trade of all major illegal drugs combined. Cyber criminals can be ruthless and cunning, striking quickly inside a tiny window of time or space with temporarily limited security.

Most major financial services firms have major technical controls, staff, and processes in place, but many smaller banks and credit unions haven’t fully invested in secure networks and IT automation to help prepare for attacks. And there are many more attacks on the horizon. According to the Cisco 2017 Annual Cybersecurity Report, for example, ransomware is growing at a yearly rate of 350%.

One of the most compelling recent examples of a cunning modern-day bank robbery occurred in February 2016 when hackers breached Swift technology to heist $81 million from the Bank of Bangladesh. The Federal Reserve Bank of New York matched a set of codes assigned to the Bank of Bangladesh inside a series of 35 transfer requests and transferred $81 million of the Bangladesh bank’s money to the Philippines.

Is cybercrime already stealing your greatest asset?

Besides the obvious and looming consequences of a cyberattack, fear of security breaches can prevent executives from spending time on larger strategic innovations. Seventy-seven percent of bank executives consider cybersecurity to be their “most concerning issue.” A major roadblock to digital innovation in large banks is the fear of a data breach as well as the resulting regulatory fines. In a recent Cisco study, 71% of banking executives said concerns over security are hindering their ability to innovate, and 39% say they have stopped a mission-critical initiative because of security problems.
