Waheba Issa Dais allegedly used several social media accounts that she hacked and took over to promote ISIS. She also maintained a "virtual library" containing instructions for makings bombs, poisons and suicide vests. Dais came to the FBI's attention after an informant, who was associated with her, feared that association would result in his/her losing top-secret security clearance with the U.S. government. The FBI investigation uncovered Dais' online conversations with people claiming to support ISIS, including one who said he wanted to plan an attack in France. An undercover FBI agent contacted Dais on Facebook, and Dais referred him to a social media channel that had instructions for making weapons, including ricin, a poison made from castor beans. Dais, who offered to work with the undercover agent on an attack in the United States, suggested placing the ricin in a government office or water reservoir.
