PHA Family Highlights: Triada (Google Online Security Blog, Jun 10 2019)
“The main purpose of Triada apps was to install spam apps on a device that displays ads. The creators of Triada collected revenue from the ads displayed by the spam apps.

Triada apps started as rooting trojans, but as Google Play Protect strengthened defenses against rooting exploits, Triada apps were forced to adapt, progressing to a system image backdoor. However, thanks to OEM cooperation and our outreach efforts, OEMs prepared system images with security updates that removed the Triada infection.”

Thanks! – Lucas Samaras
