Consider the case where a set of independent servers is used to implement redundancy for some important data. The data is lost e.g. when all the servers lose their copy, but a redundancy procedure is in place so that whenever too many copies of the data are lost, new copies are made.
Now, say that an attacker has a slow way of infiltrating each server. It would be counterproductive to cause the loss of data on one server at a time, as it would be recovered and would make the owner of the data aware that an attack is ongoing. The best solution would rather be to stay silent until control of a sufficient amount of servers has been gained, and then deliver the attack simultaneously everywhere.
An example of this strategy can be seen in Season 1 of the series Mr. Robot.
I was wondering: does this strategy (infiltrating a system one component at a time until enough control has been gained to deliver a serious attack to the system) have a name? Is there any literature discussing it?
