They are. A related example is criminal gangs tageting gun owners in France after the dataleak at the sport shooting federation. This one has been well covered. There have been a few hundred targeted robberies (on old people mostly) and one or two deaths (predictably).

In Western Europe there are also foreign burglar gangs that go on sprees for a few weeks. They're well organised but don't have time to do the stalking. They use publicly available data as much as they can.

do you have any evidence to back your claim? gangs employing teams of underage burglars assisted by risk averse adults with skills for entry and targeting are a thing. everyone has a mobile phone.

They'd buy access from someone on the dark web for $5 a day.

I'd recommend reading 'Confessions of a Master Jewel Thief' -- normal dude, just decides to spend a career stealing shit for fun.

Low-end criminals fish based on data leaks all the time. More data, especially cross-referencable data, will make this ever easier.

With the new crop of agentic coding tools, you can whip up such an app in a few hours for all burglar buddies to use.
