Skype Flooder by Revi has been updated to version 2.0. If you've never heard of it, pat yourself on the back, because you're probably not a spammer. The DIY tool is used by cybercriminals who want to trick as many Microsoft Skype users as possible into interacting with their malicious scam and spam campaigns.
Anyone can buy Skype Flooder; it's just $10. Furthermore, if you buy it now, you'll automatically receive 5,000 already-harvested Skype user names!
Here's how the tool is being advertised on underground forums:
Selling skype spammer.
I do not know whether the actual spammer for Skype, but I did for myself.
That he is able to:

Posted - Spam by country - by the nature of spam - Added search - redesigned - Added output type ------------------------ Plans - Search by kreteriyam - Increase the speed of adding people to the Skype Screen [IMG] http://[redacted] [/IMG] Writing in skype: [redacted] icq: [redacted] or hp. Price $ 10 UPD #2 If you buy 5555 + skype for free. UPD #3 Added parsing of Skype usernames.
The spamming tool can be used to harvest Skype user names by country or by gender. It can also check whether the user is online or not. The latest version also supports parsing of log files. Still, Webroot, which first profiled Skype Flooder, says it's not that bad.
"Since the tool is only capable of spreading a particular message to those who give authorization to the spammer’s account, as well as the fact that it doesn't support multiple spam accounts and proxies, it doesn't represent a scalable threat," a Webroot spokesperson said in a statement. "Instead, it primarily relies on social engineering. Although the tool is capable of segmenting the targeted population for better conversion rate, the user still has to authorize the spammer in order to receive messages from him."
To protect yourself from this DIY Skype spamming tool, ensure that only users in your contact list can send you IMs or initiate calls with you. By default, Skype allows anyone to call you.
Here's how to change these settings: Tools => Options… => Privacy => "Allow calls from... people in my Contact list only" and "Automatically receive video and share screens with... people in my Contact list only" and "Allow IMs from... people in my Contact list only."
