Recorded findings: 1 critical and 12 high severity. Read the finding details before interpreting the score; automated flags are not proof of malicious behaviour.
Automated analysis looks for suspicious code, permissions and other risk signals. It does not observe every runtime behaviour or independently audit the publisher’s servers. A low-risk result is not a guarantee of safety. How our checks work.
