Everyone around the globe has heard about the colossal Equifax breach last month. Its implications haven’t yet been fully calculated except now that the CEO has resigned from his job, we know it’s serious. However, one fact is clear – the data was exfiltrated by hackers. This isn’t the first time-sensitive information has been pumped out of a big company – Anthem, Target, Home Depot, Yahoo are a handful of the recognizable victims of theft in the last few years.
Data exfiltration is how hackers siphon out valuable intelligence from a business. Oftentimes the most insidious path is through the Domain Name System (DNS). The DNS protocol is manipulated to act as a ‘file transfer’ protocol, and by default is seen as legitimate. Most businesses don’t even know it is happening until it is too late.
