Gizmodo:

Sending pictures to others is one of the most basic functions of a smartphone, but when your phone’s texting app starts randomly pushing out photos without your knowledge, you got a problem.

And unfortunately, according to a smattering of complaints on Reddit and the official Samsung forums, it seems that’s exactly what happened to a handful of Samsung phone users, including owners of late model devices such as the Galaxy Note 8 and Galaxy S9.

And:

Samsung Messages, the default texting app on Galaxy devices, which (for reasons that haven’t been determined), is erroneously sending pictures stored on the devices to random contacts via SMS. One user on Reddit even claims that instead of sending one pic, Samsung Messages sent out their entire photo gallery to a contact in the middle of the night.

And:

The scariest part about this bug is that when Samsung Messages bugs out sends pics to other people, it reportedly doesn’t leave any evidence of it doing so, which means people may not know their photos have been released into the wild until it’s too late.

That is unbelievable.
