Security Growler

The USA’s electronic attack fighters are a unique, overworked, and nearly obsolete capability. With the retirement of the US Air Force’s long-range EF-111 Raven “Spark ‘Vark,” the aging 4-seat EA-6B Prowlers became the USA’s only remaining fighter for radar jamming, communications jamming and information operations like signals interception [1]. Despite their age and performance limits, they’ve been predictably busy on the front lines, used for everything from escorting strike aircraft against heavily defended targets, to disrupting enemy IED land mine attacks by jamming all radio signals in an area.

In 2011 Van Bitz launched the most aggressive motorhome security system available in the UK called: THE GROWLER! Please go to the motorhome security link above, for further details about basic Thatcham systems and the Growler system. Van Bitz supplies. Multiple camera monitor 1.0. Reviews from Growler USA employees about Growler USA culture, salaries, benefits, work-life balance, management, job security, and more.

All airframes have lifespan limits, however, and the EA-6B is no exception. The USA’s new electronic warfare aircraft will be based on Boeing’s 2-seat F/A-18F Super Hornet multi-role fighter, and has 90% commonality with its counterpart. That will give it decent self-defense capabilities, as well as electronic attack potential. At present, however, the EA-18G is slated to be the only dedicated electronic warfare aircraft in the USA’s future force.

DID’s FOCUS articles offer in-depth, updated looks at significant military programs of record. This article describes the EA-18G aircraft and its key systems, outlining the program, and keeping track of ongoing developments, contracts, etc. that affect the program.

February 22/19: EW Drone The US Navyplans to test its newelectronic warfare (EW) drone this fall. The dronesare part of the „Remedy“ program by the Navy and NorthropGrumman that sees a small Class II unmanned aerialvehicle (UAV) packed into a cluster munition canisterthat would then eject from a mothership and fly aprogrammed route ahead of stand-off jammers and strikeaircraft. This could mean that electronic EW platformslike theEA-18G Growler could soon release swarms of dronesfrom the aircraft, allowing the smaller vehicles to flyahead to scout out for radar and other battlefieldemitters. The drones could even take part in electronicattack missions themselves by jamming enemy sensornetworks. During the trials in fall, Northrop Grummanplans to link the drone with an actual Growler as part ofFleet Tactical Grid 2019.

This menubar app for OS X will notify you via Notification Center (or Growl) when various security events occur (see list).

It's very useful if you're paranoid about people trying to hack into your computer. Or.. if you simply like having information about people using your computer's resources.

It's extremely lightweight, the app is 3MB including the icon, with <0.01% CPU and <15MB of RAM used when running.It's easily extensible in Python, you can add parsers that detect new TCP connetions or poll logfiles.You can even forward alerts as push notifications to your iOS devices using Prowl.


  1. Download and run (dark mode)
  2. Click on the menubar icon once to start detecting events.

Download Security Growler if you don't use OS X Dark Mode.If you prefer Growl to the OS X Notification Center, run sudo easy_install gntp in Terminal and relaunch to switch.

It can do cool things like:

Alert you of attempted and succesfull SSH logins:

Notify you of incoming & outgoing TCP connections: FTP, VNC, SMB, MySQL, etc.:

(using less RAM than Little Snitch)

Security Growler Price

Notify you whenever a command is run with sudo:

Let you know when you're being portscanned:

The currently working alert types are:

  • SSH
  • FTP
  • SMB
  • AFP
  • MySQL
  • PostgreSQL
  • iTunes Sharing
  • sudo commands
  • port-scans (e.g. if you're on the receiving end of nmap)
  • VNC (detailed alerts require app is run as root)


I was tired of not being able to find an app that would quell my paranoia about open ports, so I made one myself. Now I can relax whenever I'm in a seedy internet cafe or connected to free Boingo airport wifi because I know if anyone is trying to connect to my computer.

Little Snitch is still hands-down the best connection-alerting software available for Mac, I highly suggest you check it out if you want a comprehensive firewall/alerting system, and are willing to pay a few bucks to get it. Security Growler is centered around parsing logfiles for any kind of generic pattern, not just monitoring the TCP connection table like Little Snitch. For example, my app can alert you of sudo events, keychain auth events, and anything else you can think of that's reported to a logfile. This app is significantly more lightweight than Little Snitch, it comes in at <15mb of RAM used, simply because it aims to solve a simpler problem than Little Snitch. This app is not designed to prevent malicious connections, that's what firewalls are for, it's just meant to keep an unobtrusive log, and alert you whenever important security events are happening. The more informed you are, the better you can protect yourself.

This app is meant for developers who frequenly run services that are open to their LAN, and just want to keep tabs on usage to make sure they aren't being abused by some local script kiddie. Since the target audience is developers, I opted to leave some parts a little less user-friendly, such as the config system.

Feel free to submit a pull-request and add a new parser (e.g. try writing one for nginx http-auth)!

A similar project written by @benjojo is available for Linux users: PushAlotAuth, it uses the PushALot push-notification platform.
