Recently, there has been a rash of breaches associated with US government agencies the latest being the unclassified email server used by the Joint Chiefs
Couple this with the recent Sabre breach and reported American Airline breaches and you have to wonder if foreign states are looking to cross correlate information to gain insight into where people are going and who they are meeting with.
It is plausible that foreign states could likely have information regarding where dissidents and others are traveling. With supporting intelligence, they could have the motive of working to determine if certain individuals are meeting with American intelligence agencies or military leaders. Each breach of a federal agency or organization closely tied to the government adds to the "database" being used by nation states to gather intel.
Foreign states could have the information from OPM about agency personnel’s work history and current location, and now with the Sabre and American breaches they have enough information to make a determination about who is going where and who is meeting with whom. Does it sound like something out of a movie? Yes it does, but this is real life with real lives in danger.
“The World Economic Forum (WEF) says a significant portion of cybercrime goes undetected, particularly industrial espionage where access to confidential documents and data is difficult to spot.”
Breaches are no longer about just getting Personally Identifiable Information (PII), it is becoming more and more about big data and state-level espionage. Our government, and agencies closely tied to it, need to ensure that their systems are as secure as possible to prevent the further collection of information that could help another nation state enforce their rules upon those that would look to try and effect a change within their country.
Time will tell.
