API (In)security: The Hidden Risk of Black Friday

Black Friday may be the pinnacle of the holiday shopping season, a day when online retailers experience unprecedented traffic and revenue opportunities as consumers kick off the Christmas season. For many retailers, it’s a make-or-break event. Yet, with increased traffic comes increased risk, particularly as it relates to cybersecurity and keeping shoppers safe from fraud stemming from a cyberattack on their favorite digital store. An area often overlooked in the frenzy to prepare for this critical shopping day is API security.

APIs (Application Programming Interfaces) serve as the facilitator of modern e-commerce operations, connecting mobile apps, websites, and backend systems to enable seamless shopping experiences. Retailers are particularly vulnerable as they rely heavily on APIs to handle user authentication, manage inventories, facilitate payment processing, and integrate third-party services like logistics or marketing tools.

While APIs offer unparalleled convenience and scalability, they also present a lucrative attack vector for cybercriminals. There’s no doubt that neglecting API security during Black Friday preparations could have possibly disastrous consequences for retailers.

Security vs. Speed

The harsh reality is that, for many organizations, application security posture takes a back seat to the need to develop and deploy quickly. As Black Friday approaches, the pressure to deliver new features, scale infrastructure, and ensure uptime often leads to shortcuts in security practices.

While speed-to-market is essential, failing to prioritize security can lead to devastating breaches. Cybercriminals are well aware of the vulnerabilities created by this rush and often exploit them during high-traffic events. For example, APIs without proper authentication or rate-limiting mechanisms can be targeted for account takeovers, data theft, or denial-of-service attacks. All of which can be detrimental if you’re an online retailer during the busiest shopping day of the year.

And the stakes are high. The consequences of an API breach during Black Friday can be severe. A successful attack can lead to revenue loss, customer trust erosion and operational disruption which can b
