What are cybercriminals up to in terms of TDoS attack tools? Let’s take a peek inside a recently released DIY SIP-based (Session Initiation Protocol) flood tool, which also has the capacity to validate any given set of phone numbers.
Earlier this year we profiled a newly released mobile/phone number harvestingapplication, a common tool in the arsenal of mobile spammers, as well as vendors of mobile spam services. Since the practice is an inseparable part of the mobile spamming process, cybercriminals continue periodically releasing new mobile number harvesting applications, update their features, but most interestingly, continue exclusively targeting Russian users.
In this post, I’ll profile yet another DIY mobile number harvesting tool available on the underground marketplace since 2011, and emphasize on its most recent (2013) updated feature, namely, the use of proxies.
Let’s find out by profiling a Russian DIY (do it yourself) software vendor, that’s been operating since 2011, and is currently offering a Session Initiation Protocol (SIP) based phone number verification tool, as well as USB-modem based phone number verification application.
