I must admit, that a new one on me. To the best of my recollection, I never remember seeing a photo or video of a UFO like that. First impression was it kinda looks like a Romulan battlecruiser.
I will say it's a bit suspicious the object appears absolutely fixed in space. It also looks like there was a haze or fog at altitude through the video was taken. Or it could be glare. Hard to tell what's behind the UFO.
Looking at Hadera on Google Earth, it's a coastal town about 25-30 miles south of Haifa. (There was a terror attack in Hadera just a day or two before this video was alleged to have been taken.) More interestingly, it's just a few miles west of a major Israeli air and surface to air missile base. That base is also the control center for IAF drones. (Information on the base is from Wiki, the Israelis are extremely serious about operational secrecy and notoriously tight lipped about weapon systems basing.) Difficult to believe something like that could have gotten within just a few air miles of a major Israeli airbase and just sat there without being intercepted and/or fired on. The Israelis are understandably of the "shoot first, ask questions later" mentality.
The other thing that crossed my mind after having watched the video multiple times is the layout of the light pattern formed looks like illuminated filaments in an old/early incandescent light bulb. (See below. Not a perfect match, but you get the idea.) A hoax perpetrated by photographing some type incandescent bulb, or some computer wizardry to simulate it? That would explain the stationary nature of the object and no military reaction by the IAF.
