The IDF military intelligence official expressed "heavy suspicion" that Hamas intelligence infiltrated the Israeli military before October 7. Hamas had access to sensitive information about the IDF's most classified sites, raising concerns about how this information was obtained. The officer noted that the intelligence couldn't have been acquired through conventional means like drones or observation posts, suggesting potential assistance from a foreign power. This situation was deemed a "double failure" for the Shin Bet, responsible for uncovering Hamas's plans and thwarting espionage attempts.
