The intent is to gain access to your personal information, including banking details, credit card numbers, or social security numbers. Please be aware that all legitimate SOSi communications come from official @sosi.com or @sosi.us email addresses, and we never request personal information during initial contact. Our official careers site can be found at sosi.com/careers and our corporate site at sosi.com.
