Jefferies has recently learned that unknown persons are using the Jefferies name and the names and photographs of Jefferies employees, without authorization, to offer investment clubs or other investments or employment to individuals around the world, likely for fraudulent purposes. The persons are using the Jefferies name to impersonate Jefferies on fake websites, fake mobile device software, unauthorized accounts on WhatsApp, Telegram and Instagram and unauthorized promotional items such as water bottles and other items, often in Portuguese. Jefferies does not solicit investors through WhatsApp or other social media.
