[Yehuda Ben-Hanan](/people/yehuda-ben-hanan/) was the owner of Software and Engineering Consultants, a small computer company based in Chatsworth, [California](/places/california/). He was a childhood friend of [Ari Ben-Menashe](/people/ari-ben-menashe/).

[Rafi](/organizations/rafi/) selected Ben-Hanan to develop a "trap door" for the [PROMIS](/programs/promis/) software, which would allow external access to the computers of intelligence agencies using the program. Ben-Hanan was given blueprints and set about his work for a $5,000 fee, unaware of the true purpose of the project.[^1]
