DDoS extortion-themed scam circulating

Sample message:

• "You are welcomed with a command of hackers ZeleniyHach. We hold a huge network of Distributed Denial Of Service Attack, allowing to suspend any web site. We have been watching (domainname.com) and were able to find out that you have spent pretty money much for its advancement and want to to offer you to spend a little more yet. Just as little as 200 bucks as a voluntary donation to our fund will keep your web site away from DDOS attack. 200 bucks is not so much also will help you to avoid greater problems in the future.FOR DULLS..!!! IF YOU DO NOT OFFER TO US 200 bucks WE WILL KILL YOUR WEB SITE! Unfortunately, we accept only Webmoney Paymer Cheks, so make sure to get your fat asses out and without assistance find out how to transfer money into it. We give you 48 hours. If after 48 hours we will not get 200 dollars, there is one more 0 will be added to 200 bucks, i.e. 2000 bucks and so on until you come to reason. When you are ready, just send the check as your response to this message. In subject matter of the letter specify the domain with greater letters, it is a lot of you We are the one, respect our work."

Despite the presence of "financial penalties", which is a popular tactic used in professional DDoS extortion letters, this spamvertised campaign is a clear attempt to scam the user, meaning there's a low probability that the scammers have the DDoS capabilities they're referring to.

As far as the serious underground market players are concerned, in May, 2010, a study conducted by VeriSign’s iDefense Intelligence Operations Team, concluded that the average price for renting a botnet is $67 for 24 hours, and $9 for hourly access. And although their findings entirely depend on the underground service in question/long term or short term contracting, the conclusion is rather simple - renting botnets is getting cheaper, due to the never-ending supply of malware-infected hosts.
