How to decode the obfuscated PHP code
If for some reason you have to troubleshoot the fiile or plugin with obfuscated code like this one
wp_register_script("\155\x6f\x76\x75\x6d", po_URL . "\x69\156\x63\154\x75\x64\145\163\57\152\x73\57\x75\x6d\162\x65\x67\x2e\x6d\x69\x6e\56\152\163", array("\x6a\161\165\x65\x72\x79"));
wp_localize_script("\155\x6f\166\x75\155", "\155\x6f\x75\x6d\166\141\162", array("\163\151\x74\x65\x55\x52\x4c" => site_url(), "\x6f\x74\160\124\x79\160\145" => $this->_otpType, "\x6e\157\156\x63\145" => wp_create_nonce($this->_nonce), "\x62\x75\x74\164\x6f\156\164\145\x78\164" => mo_($this->_buttonText), "\x66\x69\x65\154\x64" => $this->_otpType === $this->_typePhoneTag ? $this->_phoneKey : "\165\x73\x65\x72\x5f\145\155\141\x69\154", "\x69\155\147\125\122\114" => po_LOADER_URL));
wp_enqueue_script("\155\157\x76\165\x6d");
You can user service like this https://malwaredecoder.com/ to un-obfuscate the code.
As a result you will get this:
wp_register_script("po", po_URL . "includes/js/fake.min.js", array("jquery"));
wp_localize_script("po", "po", array("siteURL" => site_url(), "otpType" => $this->_otpType, "nonce" => wp_create_nonce($this->_nonce), "buttontext" => mo_($this->_buttonText), "field" => $this->_otpType === $this->_typePhoneTag ? $this->_phoneKey : "user_email", "imgURL" => MOV_LOADER_URL));
wp_enqueue_script("movum");
