Webroot has uncovered a budget Skype denial of service attack tool selling for just £10 on the cyber black market.
Researcher Dancho Danchev reported unearthing the tool kit designed to let criminals mount basic telephone based denial of service attacks in a blog post on Tuesday.
"The ring flooder works in a fairly simple way. Once the program detects a running Skype application, it will automatically start dialling any given number within a particular interval," he said.
Danchev added that despite retailing for a modest £10 the kit is still overpriced, thanks to the influx of new more advanced kits commonly available on most cyber black markets.
"It doesn't support multiple accounts, or malware-infected hosts as anonymisation proxies, making it a low level threat with a surprisingly high price, in this case, £10," wrote Danchev.
"Ring-based DIAL (Digitally Initiated Abuse of Telephones) type of attacks are just the tip of the iceberg, given the fact that cyber criminals also have access to SMS-based DoS (Denial of Service) attack tools."
The Webroot researcher said the tool underling the scope of attack tools on sale to would-be criminals.
"Thanks to the ease of generating a botnet, in 2013, stolen accounting data on a mass scale is a no longer a hot underground item, it's a commodity, one that's being offered by virtually all participants in the cybercrime ecosystem," wrote Danchev.
"With underground marketplace transparency now an everyday reality for the average cyber criminal [...] the entire ecosystem is empowered with the information flow generated by all the fraudulent and malicious activity going on online."
Skype has been of increasing interest to cyber criminals due to its ever growing popularity.
