Little Snitch 4.4.3

Little Snitch gives you control over your private outgoing data.

Track background activity
As soon as your computer connects to the Internet, applications often have permission to send any information wherever they need to. Little Snitch takes note of this activity and allows you to decide for yourself what happens with this data.

Control your network
Choose to allow or deny connections, or define a rule how to handle similar, future connection attempts. Little Snitch runs inconspicuously in the background and it can even detect network-related activity of viruses, trojans, and other malware.

What’s New

Version 4.5: This release brings new features and improvements requested by users, after a few months of focussing on compatibility with macOS Catalina. In particular:

Redesigned Research Assistant in Connection Alert
Since our Internet Access Policy initiative (IAP) gains popularity and support by more and more third party developers, the IAP has been made the main focus of the Research Assistant. It provides you with first hand information directly from the app developer. The information from our Research Assistant online database now comes bundled with Little Snitch to supplement processes which don’t have an IAP of their own. It’s therefore no longer necessary for Little Snitch to connect to the online database to retrieve this information. Along with connection details and possible warnings regarding code identity checks all this information is now presented in a redesigned interface, in a clear and consistent manner.
Other improvements in the Connection Alert
  • The connection alert now offers a wider range of options for the lifetime of temporary rules, ranging from 1 minute up to 30 days.
  • When a code identity check fails, it’s now always possible to “accept the modification” and update the identity check, using the executable’s cryptographic hash if nothing else is suitable.
  • When no server name can be derived and only the IP Address of a remote computer is shown, it’s now possible to create rules for the entire subnet, not just the particular IP Address.
Improvements in Network Monitor
  • Network Monitor now shows accesses to the Berkeley Packet Filter (BPF), and rules for this kind of access can now be managed from within Network Monitor as well.
  • Since BPF access can now be managed in Network Monitor, BPF related connection alerts no longer appear in Silent Mode.
  • All server names ending in .local are now grouped in one single “local” domain.
  • Improved rule creation from within Network Monitor. If a similar but currently disabled rule already exists, it is replaced by the newly created rule.
  • The context menu for a connection now offers an “Until Logout” option when the Shift key is held.
  • Fixed an issue where Network Monitor stopped showing connections.
  • Fixed an issue where macOS would change Spaces when a full screen app is active and Network Monitor is brought to front.
  • Fixed: When there are no rules matching a connection, buttons for rule creation are only shown when the mouse is at the prospective button location. This prospective location was sometimes off by half a button width, making it hard to create an allow-rule. This issue has been fixed.
  • Fixed an issue where geographic labels on the map could be off by half a map width.
Improvements in Little Snitch Configuration
  • Improved editing of a selection of multiple rules.
  • In order to derive code identity information, Little Snitch Configuration must read the executable files of processes. If an executable cannot be read due to file permissions, we now derive code identity information via a privileged component.
General improvements and fixes
  • Improved the selection of suitable sections from the Internet Access Policy of a process.
  • Little Snitch now ships with built-in Internet Access Policy information for further macOS system components.
  • Improved selection of relevant information from Internet Access Policy in Network Monitor.
  • Updated Welcome Window in Little Snitch Configuration to reflect the new design of the connection alert.
  • After a fresh installation Little Snitch Configuration no longer shows factory rules in the “Last 24 Hours” section.
  • Preventing the simultaneous display of modal alert windows, possibly covering each other. They are now displayed one after the other.
  • Fixed detection of remote endpoint name for Viscosity VPN.
  • Fixed a crash of Little Snitch when other programs write garbage to the System Configuration. This crash occurred with a Microsoft Active Directory client for macOS.
  • Numerous other bug fixes and improvements.

    My guess is that the company made a huge deal with the cracker/s so there won’t be an actual newer version cracked soon.

      I mean it doesn’t even have to be a huge deal, or even a dollar deal. If I was the cracker and I have to choose between cracking a software for nothing in return except for ungrateful freeloaders, versus well, not doing that, I’d probably choose the latter.

    Version 4.4.3 works correctly … but it crashes after a few minutes and says that the key is not valid
