Jerusalem-based nonprofit United Hatzalah, which provides emergency medical services, said its website was struck by distributed denial of service (DDoS) attacks that temporarily slowed its ability to receive donations. DDoS is a low-level and typically unsophisticated attack designed to overwhelm a website with artificial traffic, often causing it to crash. The disruptions to the United Hatzalah website did not lead to loss of data or donations, said Jeremy Cole, a spokesperson for the group. Another website impersonating United Hatzalah that had sprung up in the last few days seeking donations had been taken down, Cole said.
