I think lots of it has to do with how well the hasbara covers up the scandals from the wider publics perception, combined with the cultural bandwagon of considering them an ally even when their repeated actions say otherwise.
edit: also the idea that they have such good tech and its a pragmatic decision ignores the history of how and who they got it from and the intentions for it. I say this as someone who worked directly with Mellanox for example, before aquisition by Nvidia... I always thought kernel level shims for networking stacks from an Israeli company was dangerous... but the speeds!!!
Then the ad network delivers a targeted ad that exploits a vulnerability (eg a broken JPEG decoder that, when sent a bad image, allows to run arbitrary code on your machine), and from there you have access to the computer
It’s to do with hiding malware/spyware in an image which ends up in your cache on device. I can’t go much further into details but all this takes is for you to visit a site that serves it via ad network.
Israel has been known to have some sneaky spyware in the past with Pegasus.
- It came in through the front door. Discover-Tech ran its own ad-buying platform and was listed as a "certified" vendor by Google and IAB Europe for six years. Nothing was hacked to get in. It bid in ad auctions like any other buyer.
- The ads looked harmless. Plain banners for games, AliExpress deals and an IP-lookup site. Hidden inside each one was a small script that quietly phoned home when the ad loaded.
- Everyone who saw an ad was profiled. The script collected device details, IP addresses and, on many sites, the publisher's own cookies, sometimes including logged-in session tokens. Cookie-syncing with other ad networks built a huge identity graph.
- Only chosen targets got the payload. A gatekeeper server checked each device's ad ID and IP. Most people got nothing back. A selected target got code that handed them off to spyware maker Candiru, and the code was served only once, which made it very hard for researchers to capture.
- The handoff was built to defeat inspection. Encrypted channels, rotating hosting, anti-bot checks and even a fake "Copyright Google" comment to fool human reviewers.
- It worked. At least 45 devices at Al Jazeera were targeted, and spyware was recovered from an infected machine. Its ads also appeared on networks belonging to NATO, the UN, the European Parliament, the ICC and various defence ministries.
- The scale was huge. Billions of bids and ads in nearly 200,000 apps and websites, including Duolingo, Viber, Yahoo Mail, dating apps and period trackers, yet almost no sign of real advertisers or revenue.

Edit:
the TFA answers: "Advertisers or DSPs may run HTML and JavaScript code when an ad is shown to the user." Its wild! I thought the ads are sanitized, go through a CDR of sorts, and whatever javascript is permitted is authored by ad networks, not the buyers. Sheesh. Thats just RCE.
RTB (real-time bidding) does not incentivise publishers to care about what ads are actually being shown to individual users, so long as CPM is maximised.
