Older Versions of Safari Store Login Info in Plain Text

by

Older versions of Safari for Mac store unencrypted user login credentials in a plain text file, according to security firm Kaspersky (via ZDNet). Safari saves the information in order to restore a previous browsing session, reopening all sites, even those that require authentication using the browser's "Reopen All Windows from Last Session" functionality.

It turns out that Safari for Mac OS, like many other contemporary browsers, can restore the previous browsing session. In other words, all the sites that were open in the previous session – even those that required authorization – can be restored in a few simple steps when the browser is launched. Convenient? Of course. Safe? No, unfortunately.

Safari 6.0.5 for OS X 10.8.5 and 10.7.5 does not encrypt previous sessions, storing them instead in a standard LastSession.plist file that includes website usernames and passwords. Though the file is located in a hidden folder, it is still easily accessible and can be opened on any system.

Apple fixed this issue in Safari 6.1, which was released alongside OS X 10.9 Mavericks. Mac users running Mavericks or those who have installed the Safari 6.1 update for OS X 10.8 Mountain Lion or OS X 10.7 Lion will not be affected. This problem is limited to users running Safari 6.0.5 and can be remedied by upgrading to the latest software.

Thats totally misleading, firstly there is no point in encrypting data which can be seen in the browser address bar when the previous session is restored. Secondly, those are url params, sent in plain text over the wire. The problem with the example shown is not at the browser end, its the site at the other end which uses url params for auth over http not https.

Has nobody looked at Firefox's Saved Passwords feature? Literally the only security is a button labeled "Show Passwords". And it's been that way for years.

But you need to enter the Master Password to see them and the file that contains the passwords on the filesystem has its contents encrypted so not the same at all

If the password is visible in plaintext, it means the NSA will catch more terrorists. So this is basically a good thing.
