According to McAfee, the ignorance over AETs comes at a high price in terms of data breaches, an average of $931,000 per incident using its own research to be precise. This climbs to $2 million a pop in financial services.
The company concedes that such attacks aren't caused by AETs alone but sees the attack technique as an important piece of engineering for siphoning data out of networks without security systems detecting what is going on.
McAfee does at least now offer a free tool, Evader, that security teams can use to test their equipment against known AETs probes. CIOs, prepare to be shocked - and enlightened.
