Replying to a post about this alert warning against using public phone chargers in case they were modified to install malware.
The other day I was wondering how effective the default “no data transfer” mode on Android is at protecting against this type of attack. Unfortunately the articles I found tend toward either “malware could get around that too! Even if your phone is off!” or “this has yet to be seen outside security conference demos.” So, not terribly conclusive!
