The WiFi Pumpkin Is The WiFi Pineapple We Have At Home

October 27, 2022 by Lewin Day 5 Comments

While networking was once all about the Cat 5 cables and hubs and routers, now most of us connect regularly in a wireless manner. Just like regular networks, wireless networks need auditing, and [Brains933] decided to whip up a tool for just that, nicknaming it the PumpkinPI_3.

The build is inspired by the WiFi Pineapple, which is a popular commercial pentesting tool. It runs the WiFi Pumpkin framework which allows the user to run a variety of attacks on a given wireless network. Among other features, it can act as a rogue access point, run man-in-the-middle attacks, and even spoof Windows updates if so desired.

In this case, [Brains933] grabbed a Raspberry Pi Zero W to run the framework. It was stuffed in a case with a Alfa Network AWUS036NHA wireless card due to its ability to run in monitoring mode — a capability required by some of the more advanced tools. It runs on a rechargeable LiPo battery for portability, and can be fitted with a small screen for ease of operation.

It should prove to be a useful tool for investigating wireless security on the go. Alternatively, you can go even leaner, running attacks off an ESP32.

Pentesting Hack Chat This Wednesday

May 11, 2020 by Dan Maloney 3 Comments

Join us on Wednesday, May 13 at noon Pacific for the Pentesting Hack Chat with Eric Escobar!

Ask anyone in this community to name their dream jobs and chances are pretty good that penetration tester will be somewhere on the shortlist. Pentesters are allowed — nay, encouraged — to break into secure systems, to test the limits and find weak points that malicious hackers can use to gain access. The challenge of hacking and the thrill of potentially getting caught combined with no chance of prosecution? And you get paid for it? Sounds good to us!

Professional pentesting is not all cops-and-robbers fun, of course. Pentesters have to stay abreast of the latest vulnerabilities and know what weaknesses are likely to exist at a given facility so they know what to target. There are endless hours of research, often laborious social engineering, and weeks of preparation before actually attempting to penetrate a client site. The attack could be as complex as deploying wireless pentesting assets via FedEx, or as simple as sprinkling thumb drives in the parking lot. But when it comes, a pentest often reveals just how little return companies are getting on their security investment.

As a consultant for a security firm, Eric Escobar gets to challenge companies on a daily basis. He’s also a regular on the con circuit, participating in challenges like Wireless CTF at DEF CON… until he won too many times. Now he helps design and execute the challenges, helping to share his knowledge with other aspiring pentesters. And he’ll stop by the Hack Chat to do the same with us, and tell us all about the business of keeping other businesses in business.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, May 13 at 12:00 PM Pacific time. If time zones have got you down, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about. Continue reading “Pentesting Hack Chat This Wednesday” →

Fail Of The Week: Padlock Purports To Provide Protection, Proves Pathetic

January 21, 2020 by Dan Maloney 49 Comments

Anyone in the know about IoT security is likely to steer clear of a physical security product that’s got some sort of wireless control. The list of exploits for such devices is a long, sad statement on security as an afterthought, if at all. So it’s understandable if you think a Bluetooth-enabled lock is best attacked via its wireless stack.

As it turns out, the Master 5440D Bluetooth Key Safe can be defeated in a few minutes with just a screwdriver. The key safe is the type a realtor or AirBnB host would use to allow access to a property’s keys. [Bosnianbill] embarked on an inspection of the $120 unit, looking for weaknesses. When physical attacks with a hammer and spoofing the solenoids with a magnet didn’t pay off, he decided to strip off the resilient skin that Master so thoughtfully provided to prevent the box from marring the finish of a door or gate. The denuded device thus revealed its awful secret: two Phillips screws, each securing a locking shackle to the cover. Once those are loose, a little prying with a screwdriver is all that’s need to get the keys to the kingdom.

In a follow-up video posted later, [Bill] took a closer look at another key safe and found that Master had made an anemic effort to fix this vulnerability with a squirt of epoxy in each screw head. It’s weak, at best, since a tap with a hammer compresses the gunk enough to get a grip on the screw.

We really thought [Bosnianbill]’s attack would be electronic, like that time [Dave Jones] cracked a safe with an oscilloscope. Who’d have thought a screwdriver would be the best way past the wireless stack?

Smart Gun Beaten By Dumb Magnets

July 25, 2017 by Michael Uttmark 221 Comments

[Plore], a hacker with an interest in safe cracking, read a vehemently anti-smart-gun thread in 2015. With the words “Could you imagine what the guys at DEF CON could do with this?” [Plore] knew what he had to do: hack some smart guns. Watch the video below the break.

Armed with the Armatix IP1, [Plore] started with one of the oldest tricks in the book: an RF relay attack. The Armatix IP1 is designed to fire only when a corresponding watch is nearby, indicating that a trusted individual is the one holding the gun. However, by using a custom-built $20 amplifier to extend the range of the watch, [Plore] is able to fire the gun more than ten feet away, which is more than enough distance to be dangerous and certainly more than the few inches the manufacturers intended.

Not stopping there, [Plore] went to the other extreme, creating what he calls an “electromagnetic compatibility tester” (in other words, a jammer) that jams the signal from the watch, effectively preventing a legitimate gun owner from firing their gun at 10 to 20 feet!

Not one to call it quits, [Plore] realised that the gun prevented illicit firing with a simple metal pin which it moved out of the way once it sensed the watch nearby. However, this metal just happened to be ferrous, and you know what that means: [Plore], with the help of some strong magnets, was able to move the pin without any electrical trickery.

Now, we’ve already covered the many hurdles that smart guns face, and this specific investigation of the state of smart gun technology doesn’t make the picture look any brighter. We’re aware that hindsight is always 20/20, so let us know in the comments how you would fix the problems with the Armatix IP1.

RFID Reader Snoops Cards From 3 Feet Away

November 3, 2013 by Marsh 60 Comments

Security researcher [Fran Brown] sent us this tip about his Tastic RFID Thief, which can stealthily snag the information off an RFID card at long range. If you’ve worked with passive RFID before, you know that most readers only work within inches of the card. In [Fran’s] DEFCON talk this summer he calls it the “ass-grabbing method” of trying to get a hidden antenna close enough to a target’s wallet.

His solution takes an off-the-shelf high-powered reader, (such as the HID MaxiProx 5375), and makes it amazingly portable by embedding 12 AA batteries and a custom PCB using an Arduino Nano to interpret the reader’s output. When the reader sees a nearby card, the information is parsed through the Nano and the data is both sent to an LCD screen and stored to a .txt file on a removable microSD card for later retrieval.

There are two short videos after the break: a demonstration of the Tastic RFID Thief and a quick look at its guts. If you’re considering reproducing this tool and you’re picking your jaw off the floor over the price of the reader, you can always try building your own…

Ubuntu Laika – An Android Phone Pen Testing Platform

June 9, 2011 by Mike Nathan 11 Comments

Once [Ruan] over at AndroidClone heard that Android devices were capable of running a full Linux environment, he started contemplating all of the things he might be able to do with a full Linux OS in his pocket.

He decided that a portable penetration testing platform would be great to have on hand, so he got busy installing Ubuntu 10.10 on his Lenovo LePhone. Once he had it up and running, he stripped out all of the unnecessary fluff and added some common tools such as Wireshark, Nmap, and Kismet, among others. He says it easily runs side by side with Android, allowing you to switch between the Ubuntu install and your standard Android applications with ease.

While this all started out as a proof of concept, he has continued to refine the project, releasing several new versions along the way. If you are interested in giving it a try, he has installation instructions available in the AndroidClone forums.

Portable WiFi Penetration Testing

August 14, 2010 by Mike Szczys 25 Comments

Inside this box you’ll find a La Fonera wireless access point. [Emeryth] and his band of miscreants built this portable device for WiFi security testing. The AP is running OpenWRT and has been set up to use the 16×4 character display as a terminal. An ATmega88 connects the LCD as well as six buttons to the UART of the La Fonera. From there, a set of Ruby scripts takes care of the communication protocol. As you can see after the break, this setup allows you to scan the area for WiFi, showing channel, SSID, and MAC information. Although not specifically outlined in the video we suspect there’s some more devious tricks up its sleeve too.
