To be fair, the sharer may have just been quoting the ABC's own words. Clickbait is their MO of late, and their app is the worst for it. The website used to be better.
EDIT: the link in the app phrases it "The world's largest home robotics company has a problem - its vacuum cleaners can be hacked from afar".
The ABC News website (the Australian one) has been doing A/B testing on headlines for years. It's super common to see two or three different versions of the headline in the first hour or so after an article's publication, and then settle onto the presumably best click thru one. It used to show up pretty obviously when the url didn't match the headline, but I'm not sure if that's still true after their recent (awful) website redesign.
