Persistent mystery app “clo” showing all signs of being malware
I discovered a mysterious app in my iPhones and iPads that I can’t get rid of, and the date showing as its installation date coincides with the time I started to notice some obvious evidence of hacking, such as temporary (but brief) control of my screen, and deletions of photos that I didn’t do.
The app is called “clo” (all lowercase) and appeared only in the Passwords app and in Sign In With Apple. I was able to delete it easily from Passwords without having it return. On Sign In With Apple, though, it returns immediately after I click “Stop Using” then “Delete”. Every other app I had there was easily removed with those two steps.
Apple engineers are looking into this but I have not received any real new information on what the app is or how to get rid of it.
Has anyone else encountered “clo”?
