Stalking events led to discovery of covertly installed keyloggers on iPhones،
They will be your own people
Certo has discovered that online criminals are offering keylogger services to those who want to keep tabs on someone they know. For just $30, people can secretly install a malicious app with a third-party keyboard on someone's phone.
The keyboard equipped with a keylogger records and sends all inputs made by the victim. This allows the hacker and his accomplice to access messages, names of websites visited by the target, two-factor authentication codes and passwords.
Because the apps are distributed through TestFlight, they avoid the strict process that apps destined for the App Store go through.
Default iPhone Keyboard vs Custom Keyboard with Keylogger
Custom keyboards look like the iPhone's default keyboard, so most people won't realize there's anything fishy going on. The only way to check them is to go to Settings, then tap General, then select Keyboard, then go to Keyboards.
If you see a third keyboard besides “English (US)” and “Emoji” that you don't remember having installed, you need to get rid of it by tapping “Change” and selecting “Remove.”
Certo became aware of this campaign when she heard about several incidents of cyberstalking in which the harassers knew everything a victim had typed on their phone.
