Julio Cesar Fort has started putting together a curated list of penetration testing reports from a variety of security consultancies. While the list is new, and not exhaustive yet, it’s on the right track and I look forward to seeing it grow. It’s always interesting to see how different companies do their reporting, and there is a lot to be learned in these reports. If you’re a professional penetration tester, the layout, structure and formatting choices are probably more interesting than the actual content in this case.
The list is on GitHub, so I’m sure we’ll start seeing others contributing soon: https://github.com/juliocesarfort/public-pentesting-reports
Following on from my linux bash honeyport script (read this first if you don’t know what a Honeyport is), I wanted to write a script that works across platforms to accept connections on a given port and block that IP using the local firewall – IPFW on Mac OS X, iptables on Linux, or Windows Firewall – or using the Dome9 service (I’m hoping to add Unix support soon).
I chose to write this one in Python as the cross-platform language of choice, and it’s compatible with Python 2.7 to 3.4. One feature of this script is that you can optionally configure it to run another Python script whenever a client connects to the honeyport. The client’s IP will be passed to the called script as an argument, allowing you to do whatever you want with it. The script’s output is then sent back to the connected client before they are blacklisted.
Check it out on GitHub, improvements and additional ideas are welcome!
Dome9 just introduced the ability to set a time-to-live (TTL) option for blacklisted IPs, something I may have bugged them for about once or twice! This is nice as it allows items on your blacklist to expire after a pre-determined amount of time instead of living on in perpetuity. It’s particularly beneficial when you run something like my Honeyport that can end up blacklisting over 400 unique IPs in about two months — it saves having to go in and manually remove blacklisted IPs periodically.
I’ve updated my Honeyport script to include the option to set a TTL on blacklisted IPs when using Dome9. Note this doesn’t yet work when using IPtables as it doesn’t have an easy TTL-style option for rules. This functionality for IPtables is on my TODO list.

After securing systems by hiding them completely from the network/internet using Single Packet Authorization, I’ve recently been interested in doing more so-called ‘active’ defense, by implementing solutions to delay, confuse, or thwart attackers. Completely hiding one’s system is not always feasible (ie. in the case of an internet-facing server), and monitoring, apart from being purely reactive, is not always easy and requires the involvement of a human. An alternative to these is to do some automated active defense. One simple tool in the bag of active defense tricks is the honeyport. Read more
Forget for a moment that the following video is a trailer for an upcoming Tom Clancy game, because it’s beautifully done and highlights a real danger that our world faces as we rely more and more of increasingly fragile systems and infrastructure. I think the things depicted in the video are a far bigger threat than things like terrorism, yet are hardly addressed today.
For those of you actually interested in the game, this gameplay trailer looks pretty cool.
A new version of iOS, a new lockscreen/passcode bypass! Luckily this one was caught early in the first Beta of iOS 7 released to developers at WWDC 2013. Although this lockscreen bypass is simpler than some of the previous ones that required some tricky steps to pull off, it’s probably worth pointing out that it will only allow access to the phone’s photos, and the ability to delete, email, tweet or upload the stored image files. It does not allow access to any other apps.
I should point out that I played with iOS 7 for a day, and it was so buggy that I had to downgrade back to iOS 6. Luckily Apple has plenty of time to fix all these issues come the release date this fall.
To bypass the lockscreen simply follow these easy steps:
- Pull up the Control Center
- Tap the Calculator icon to open it
- Pull up the Control Center again
- Tap the Camera icon to open it
- Tap the photos icon in the bottom-left corner to get full access to the photos
Check out the video below to see it in action.
Those of you who have been diligent in securing your iOS devices with passcodes, wiping and Find My iPhone, just to have a thief restore your device and keep on going – well – your prayers have been answered. Coming in iOS 7 is a great feature called ‘Activation Lock’.
With Activation Lock enabled, even if your iPhone or iPad is restored to its factory settings, the user will need to activate the device using the Apple ID of the previous user. Also, if the device was put into Lost Mode in Find My iPhone, the lock screen will continue to display the fact that it is lost until the device is activated.
This is a hugely useful feature that, if used properly, will make iPhones and iPads a significantly less attractive target to thieves, as the stolen devices would be rendered useless to them. It was nice to see Apple address one of the main concerns that users have been expressing about the bypass-ability of Find My iPhone. Check out Protecting and Recovering Your iPhone and iPad from Loss and Theft (will be updated soon with this new feature).
