This is a good long form piece by Thomas Rid on disinformation activities, with a particular focus on Russian operations. A key takeaway for me is that there is a real potential for the exposure of disinformation campaigns to beget subsequent campaigns, as the discovery (and journalistic coverage) of the initial campaign can bestow a kind of legitimacy upon adversaries in the eyes of their paymasters.
A way to overcome this ends up being the adoption of tactics that not just expose disinformation campaigns but, also, actively work to disable campaigners’ operational capacities at technical as well as staff levels. Merely revealing disinformation campaigns, by way of contrast, can serve as fuel for additional funding of disinformation operators and their abilities to launch subsequent campaigns or operations.
