The seller also offers a one-week testing server for $1,000, during which time a potential client will have access to the malwares control panel. The preferred payment methods for this deal are various forms of e-currency such as Perfect Money and Bitcoin. The authors promise to develop new modules for the malware (which will be charged separately), along with updates and bug fixes.”]
