Most soccer fans will tell you that most goals are the result of a lapse in defensive concentration rather than any particular brilliance on the part of the offense. The same can be said of data breaches, the largest of which can often be attributed to human error.
The 2013 Target data breach, for example, was set into motion when Target gave external network access to a third-party contractor and forgot to cordon them off when the work was done. Hackers infiltrated Target’s network through one of the contractor’s unsecured devices and managed to install malware on Target cash registers. By the time Target discovered the source of the breach, the damage was done.
In the wake of their much more disastrous breach, Equifax found that their network was compromised thanks to a simple flaw that went unnoticed for two months. And the hits just keep coming; details are still hazy, but it recently came to light that Big Four accounting firm Deloitte has been struggling to contain a major data breach since March.
