For a dictator, the truth hurts, and that includes what’s written on the Internet.

Killcastro at the Killcastro blog is a computer wizard more than a little familiar with the tactics of hackers and cyberattacks, and he’s always alert to trouble from the dictator Havana.

He got one this week from a group that appeared to be from the U.S., but when he probed it a little further, found its base in Havana, Cuba. It was at a location near Hotel El Nacional, a ritzy place in Havana, where the G-2, Cuba’s secret police, are known to have haunts. I Googled the address for him earlier this week and sent his partner a photo of the place.

Killcastro continued further, and found that Cubanology also suffered the same kind of cyberattack intended to shut these dissident bloggers down. Cubanology probed more and found that Castro appears to be selling Web space for cyberattacks against dissident bloggers, in what surely must be one of the strangest forms of warfare ever devised. He’s got the price sheet posted on his blog, and cautions visitors against opening up certain kinds of Castro-origin email.

It’s truly one of the wildest things I’ve seen. This isn’t conspiracy theory stuff, these guys have the goods. Cubanology’s post is here, and Killcastro’s latest comment on it is here.
