Yes – but not just negatively. In my experience security professionals often explain to the board and senior leaders that a cyber-breach could devastate the share-price and investor relations. But is this right?

eBay recently posted a 13% increase to their quarterly revenue despite suffering a major cyber-attack that caused some 145 million customers’ data to be disclosed to malicious hackers and sold on the black-market.

But they are not alone. Over the past few years we have seen an insurmountable amount of data-breaches at high-profile organisations; Adobe, JP Morgan, Apple, Evernote and now eBay to name just a few, and the one thing they share in common is that their share-prices either suffered a minor decline, or rose quickly in the subsequent weeks. Clearly there is more to consider.

The issue of data-loss is just one of countless things that can affect share-price and in reality it entirely depends on the circumstances and surrounding events. The events that truly affect share-price are those that cause a ripple effect of negative incidents that have a far reaching impact on reputation.

That is why in the event of a breach, investors, stakeholders and business-leaders should not just focus on the trigger, but also on the compounding effects of a breach, such as the theft of intellectual property, regulated information, corporate strategies for planned M&As and other information at the heart of the business. Indeed, some cyber-attacks won’t involve the issue of data and will instead focus on knocking out a business’s online consumer services.
