This release contains changes in the following areas:

Improved detection of program modification

As Little Snitch consists of multiple parts it is essential to run the Little Snitch Uninstaller to make sure all components are removed from your system. Little Snitch 3.4 or newer automatically starts the uninstaller as soon as you move the Little Snitch Configuration into your trash. Oct 12, 2017 I had it with Little Snitch 4.05 and also now with Little Snitch 4.1.3 nightly (kernel 5180). MacOS 10.13.6 High Sierra At this point, if you're using the latest version of Malwarebytes for Mac, the problem does not lie with Malwarebytes.

Little Snitch has a security mechanism that ensures rules are only applied to programs for which they were originally created. This is to prevent malware from hijacking existing rules for legitimate programs. To do that, Little Snitch must be able to detect whether a program was modified. How Little Snitch does that changes with this version.

Previous versions required a program to have a valid code signature in order to be able to detect illegitimate modifications later on. Programs without a code signature could not be validated and Little Snitch warned accordingly. The focus was therefore on a program’s code signature.

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 is now on checking for modifications with the best means available. 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. (There’s still a warning if a process is not signed, but only to inform you about a possible anomaly.)

This change leads to a different terminology. 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”).

Instead of a “code signature mismatch”, Little Snitch’s connection alert now informs that “the program has been modified”.

In cases where Little Snitch detects such a modification, it now also better explains the possible underlying cause and the potential consequences.

Configuration File Compatibility

This version uses a new format with speed and size improvements for the configuration file in which the current rule set and the preferences are stored. This new file format is not compatible with older versions of Little Snitch, though.When updating to Little Snitch 4.3, the old configuration file is left untouched in case you want to downgrade to a previous version of Little Snitch. All changes made in Little Snitch 4.3 or later are not included in the old file, of course.Note that backup files created using File > Create Backup… in Little Snitch Configuration use the old file format and are therefore backward-compatible with previous versions of Little Snitch.

Improved Support for macOS Mojave

  • Improved appearance in Dark Mode.
  • Fixed backup restore from Time Machine not working in Little Snitch Configuration due to the new “Full Disk Access” security mechanism.
  • Fixed creating Diagnostics Reports for non-admin users (on macOS High Sierra and later). When you contact our tech support, we sometimes ask you to create these reports.

Performance Improvements

  • Improved overall performance for large rule sets.
  • Reduced CPU load of Little Snitch Daemon during DNS lookups.
  • Reduced CPU load of Network Monitor while inactive.
  • Improved performance of rule sorting in Little Snitch Configuration, which leads to better overall performance.
  • Fixed Little Snitch Daemon hanging while updating a rule group subscription that contains many rules.
  • Fixed a memory leak that occurred when closing a snapshot window in Network Monitor.

Internet Access Policy

  • Fixed an issue causing an app’s Internet Access Policy not being shown if that app was running in App Translocation.
  • Fixed clickable links not working in the “Deny Consequences” popover when creating rules in connection alert or Network Monitor.
  • Internet Access Policy file: Fixed large values for a connection’s “Port” being rejected.

Process Identity and Code Signature Check Improvements

  • Added support for detecting revoked code signing certificates when checking a process’ code signature. The connection alert and Network Monitor now treat such processes like processes without a valid code signature and show relevant information. Also, rules created will use an appropriate identity check (based on the executable’s checksum, not based on the code signature).
  • When showing a connection alert for a process that has no valid code signature, Little Snitch now tries to find out if loading a shared library may have caused the issue with the code signature. If so, this is pointed out in the connection alert.
  • Fixed handling of app updates while the app is still running: Previous versions of Little Snitch would complain that the code signature could not be checked if the running app was replaced on disk, e.g. during an update.
  • Fixed an issue where connection alerts would erroneously contain a warning that an application’s code signing certificate was unacceptable. This mainly happened when a process’ first connection was an incoming connection.

Improved Handling of Connection Denials and Override Rules

  • Improved handling of override deny-rules that were created as a consequence of a suspicious program modification (“Connection Denials”). In Network Monitor, these rules are now marked with a dedicated symbol. Clicking that symbol allows to remove that override rule, if the modification is confirmed to be legitimate.
  • Changed override deny-rules created for failed code identity checks to not be editable or deletable. Instead, double-clicking such a rule allows you to fix the underlying issue, which then automatically deletes the override rule.

UI and UX Improvements

  • Automatically combine rules: For improved handling of large rule sets with many similar rules that only differ in host or domain names. This is common when subscribing to blocklists, which may contain thousands of similar, individual rules denying connections to various servers. The new “Automatically combine rules” option in Little Snitch Configuration (on by default) now combines such similar rules into a single row, making it much easier to keep track of large lists of rules.
  • Improved appearance when Accessibility option 'Increase contrast' is active.
  • Improved floating window mode in Network Monitor.
  • When choosing File > Restore from Backup in Little Snitch Configuration, the list showing possible backup files now includes backups that Little Snitch created automatically.
  • Improved the map shown in the “Known Networks” window in Little Snitch Configuration.
  • Improved the legibility of traffic rates in the status menu on Retina displays.
  • Fixed data rates shown in Network Monitor to match the values shown in the status menu.
  • Fixed the “Duration” setting in Preferences > Alert > Preselected Options not being respected.
  • Fixed an issue with “undo” when unsubscribing from a rule group or when deleting a profile.
  • Fixed an issue in Little Snitch Configuration where the “Turn into global rule” action did not work.
  • Fixed an issue where an error that occurred in the course of a previous rule group subscription update was still displayed, even though the problem no longer existed.

Other Improvements and Bug Fixes

  • Increased the maximum number of host names allowed in a rule group subscription to 200.000.
  • Fixed an issue causing XPC services inside bundled frameworks to not be recognized as XPC. This resulted in connection alerts to be shown for the XPC services themselves instead of for the app the service belongs to.
  • Fixed an issue causing Time Machine backups to Samba servers to stop working under some circumstances.
  • Fixed an issue related to VPN connections with Split DNS configuration that caused only the server’s IP address to be displayed instead of its hostname.
  • Reduced the snap length in PCAP files, allowing them to be analyzed not only with Wireshark but also with “tcpdump”.

If you’re an iOS developer, this will make you very happy: Little Snitch 3.5 greatly improves support for iOS Simulator apps in every regard.

First and foremost, apps and processes that run in iOS Simulator are now easily recognizable by their name. For example, the iOS version of Safari is shown as “Safari (iOS)”:

Paths to iOS Simulator apps are clearly marked with a prefix. For stock apps like Safari, Maps or an iOS system daemon, Little Snitch will show “iOS Simulator” followed by the full path to the app’s or process’ binary. That path will be somewhere deep inside the Xcode app bundle, as can be seen in the Network Monitor’s inspector:

Here comes the interesting part: What about apps that you as an iOS developer create and then test in iOS Simulator? If you ever poked around the file system and tried to find out how Xcode and iOS Simulator manage your apps on disk, you probably discovered a path that looks like this:

~/Library/Developer/CoreSimulator/Devices/97F0609B-D9D5-4B8B-A56E-170254F30F6B/data/Containers/Bundle/Application/A3CE365D-E348-439B-871A-A2884409831B/Test.app

Little

Every app you test resides in a directory somewhere inside your home directory’s hidden Library folder whose name is a random unique identifier (UUID) that is generated for every combination of iOS version and iOS device flavor you test against which contains another random unique identifier and then your app. To top it all off, different versions of Xcode have different directory structures for all this (the above example is from Xcode 6).

In previous versions of Little Snitch all this caused problems because rules in Little Snitch are created for a process at a certain path. This means if you create a rule for an app, it only works as long as the path stays the same. Now, iOS Simulator apps don’t play nicely with this because every time Xcode and iOS Simulator decide to use a new path, you’d get a Connection Alert from Little Snitch when your app tried to do some networking.

Little Snitch 3.5 solves this problem by becoming aware of which apps on your Mac are actually run in iOS Simulator and whether they reside in one of iOS Simulator’s random container paths. For such apps, a rule’s path is automatically shortened to something like “iOS Simulator → Test.app/Test” and it just works regardless of what the exact path is.

There’s nothing special you have to do as an iOS app developer. Rules can be created like any other rule using the Connection Alert, Network Monitor or Configuration.

As a bonus, when creating a new rule in Little Snitch Configuration you get a list of all the apps that are currently installed in any of your iOS Simulator configurations, allowing you to create rules very easily:

Little Snitch Daemon App

Despite adding all of these improvements to Little Snitch, we made sure this convenience doesn’t open up any security holes whereby a malicious app could trick Little Snitch into allowing network access by just moving itself into an iOS Simulator container directory.
