(CNN) Attackers sent videos of flashing and strobing lights to people on Twitter last month as part of a cyberattack which deliberately targeted people with epilepsy. The attacks targeted the Twitter feed of the Epilepsy Foundation, the organization said MondayUsing the foundation's handle and hashtags, the attackers posted videos and GIFs that used triggering light flashes. And they did it during National Epilepsy Awareness Month in November -- when the greatest number of people with epilepsy would be following the account. The Foundation identified at least 30 different accounts participating in the calculated action, Allison Nichol, the Epilepsy Foundation's director of legal advocacy told CNN. The Foundation said it has filed criminal complaints with law enforcement and will cooperate with them to ensure the attackers "are held fully accountable."
