Signal has fixed a serious bug in its Android app that, in some cases, sent random unintended pictures to contacts without an obvious explanation.
Although the issue was reported in December 2020, given the difficulty of reproducing the bug, it isn’t until this month that a fix was rolled out to the Android users of the end-to-end encrypted messaging app.
Random images sent out to wrong contacts
This month Signal patched a bug affecting their Android app users under some circumstances.
When sending an image using the Signal Android app to one of your contacts, the contact would occasionally receive not just the selected image, but additionally a few random, unintended images, that the sender had never sent out.
