It could be a plugin but you can easily create a similar look without a plugin. Here’s what I would do (although I’m sure there are 17 better ways).
Create a text layer and type a character… any character, using a font/symbol set you like the look of. In the example you showed, it looks like there are several characters in a vertical line, so perhaps type a character, hit return, type a character, hit return, etc…
Twirl down the layer properties, than twirl down Text.
Click on the Animate flyout and select “Character Offset”.
Keyframe the Character Offset so the values of the characters you’ve typed change every frame (or however rapidly you want them to). Somebody will probably suggest an expression you can use to do the same thing… I’m as sharp as a marble and don’t know much about expressions.
I would suggest creating this text layer as a separate comp, perhaps called “Flicker text”. Now, whenever you want that effect simply add that comp above your video layer and start messing around with the text color, transfer modes, opacity, scale, position, maybe even a bit of fast blur, to get the look you want.
On your example it seems like not only are the characters changing, bu their position is dropping vertically. Simply keyframe the “Flicker text” comp’s position to do that.
That’s what I would do, hope it helps.
