When editing a rule, Little Snitch Configuration no longer shows a checkbox titled “requires valid code signature” but instead one that is titled “check process identity” (or if the rule is for any process: “apply to trusted processes only”) This change leads to a different terminology. (There’s still a warning if a process is not signed, but only to inform you about a possible anomaly) That is usually still the code signature but for programs that are not code signed, Little Snitch now computes a secure hash over the program’s executable.
The focus is now on checking for modifications with the best means available. Beginning with version 4.3, Little Snitch can always check whether a program has been tampered with, even if it’s not code signed at all. The focus was therefore on a program’s code signature Programs without a code signature could not be validated and Little Snitch warned accordingly. Previous versions required a program to have a valid code signature in order to be able to detect illegitimate modifications later on. How Little Snitch does that changes with this version To do that, Little Snitch must be able to detect whether a program was modified. This is to prevent malware from hijacking existing rules for legitimate programs. Little Snitch has a security mechanism that ensures rules are only applied to programs for which they were originally created. ★ BSc.Improved detection of program modification:
