Apparently UGNazis succeeded in obtaining login details from the billing software's host by using social engineering. UGNazis accuse WHMCS of knowingly offering services to fraudsters. After almost 24 hours UGNazis still seem to have control of WHMCS twitter account @whmcs and is regularly updating their exploits. These tweets are also feeding into WHMCS software."
