First I saw this, and thought this certainly isn't deterrence and it doesn't look like something CSIS would propose as a viable sole action to deter North Korea from conducting cyber attacks.

Outside information questioning Kim's legitimacy can be response to N.K. cyber attacks: CSIS report
Then I found and read the report (executive version), and the recommendations are fortunately more comprehensive than simply pushing more information to the North.

NORTH KOREA’S CYBER OPERATIONS: STRATEGY AND RESPONSES
It identifies four policy objectives:
Provides four recommendations for the U.S., and then provides seven recommendations (culturally insensitive) for the U.S.-ROK Alliance, one of which was Consider .
By all means keep pumping information into North Korea, in fact governments can't stop it, because if they stop non-state actors are engaged in their own information campaign against the backwards and incredibly cruel KJU regime. North Korea a festering wound from the 20th Century that continues to threaten regional and increasingly global stability, not to mention the human rights atrocities.
However, I don't think the use of information is an effective deterrent if we're truly talking deterrence. For one, this implies we would only push information north in response to a provocative act (cyber attack, nuclear weapons test, long range missile test, a kinetic engagement). While the ROK PSYOP unit may only blare it loud speakers near the border in response to a provocative attack, others are pushing information via balloons and items smuggled across the border such as DVDs. The Kim family façade is slowly cracking, we should never stop pushing the truth forward, and using it as a deterrence implies we would do just that if North Korea ceased the undesired behavior. Second, if anything, the information is provocative and North Korea is hardly deterred by it. They continue to conduct cyber activities, test long range missiles, and recently conducted another nuclear weapons test.
A recent article in the strategist indicates some of the information warfare activities ongoing.

Information Warfare: North Korea Surrenders To The Future
It appears that even North Korea can't resist the ever growing integration of globalization. That will hopefully be a good thing.
