Norton Identity Safe has a vulnarability to Keyloggers.
First of all I am aware that non of all Norton Security softwares(NIS,NAV,NS NSBU and N360) permits any spyware by default, however it should be noted that Norton Identity Safe can also be downloaded as an independent and standalone software to be installed even if non of the Norton Security software(NIS,NAV,NS NSBU and N360) is installed. What this simply means is that it can be installed on the computer which has a keylogger/spyware installed and can hence expose all the logins stored in it(Norton Identity Safe), if its credentials are captured.
It should be noted that spwares are installed in various form and ways e.g. it can come as a browser plugin or a even a trojan of which none of them may be installed at will.
My recomendation is that Symantec should consider creating and embeding a virtual keyboard in their Security Softwares and Norton Identity Safe.
