Galncing at the source it seems that all the "updates" are just startup number + random value.
http://cybermap.kaspersky.com/data/events/1.json
(where "1" would be replaced with some time value)
Edit: investigating a bit more, there are 24 URLs for http://cybermap.kaspersky.com/data/events/<H>.json where <H> starts at zero. So you can see if tomorrow the files are all different. It could very well be near-time, maybe with 1 hour of lag/caching.
It's a visualisation of the events generated by their security software.
For example when the anti-virus finds an infected file. Or the email attachment scanner finds a threat, etc...
