The Islamic State of Iraq and Syria (ISIS) is a spinoff of the al-Qaida terrorist group active in the Middle East. ISIS is believed to be taking in an estimated $3 million a day in illicit proceeds to fund its cause. The group generates funds through the following:Donations from wealthy individuals from the Persian Gulf, kidnapping and ransom. Recruitment and propaganda efforts have a global reach and are aimed at young people who are adept with the Internet and social media. The use of social media has not only helped raise funds for the extremist group, but also consistently aids it in its recruitment efforts.”]
