This edition also features expanded Flight Autonomy with 5-direction obstacle sensing and 4-direction obstacle avoidance. It uses the same camera as the first iteration of the Phantom 4 Pro. The DJI Phantom 4 Pro V2.0, announced in May 2018, improves on the existing Phantom 4 Pro with an OcuSync transmission system, improved ESCs and low-noise propellers. Some build quality upgrades are included with the camera gimbal being made of magnesium. Phantom 4 Pro Obsidian Īnnounced at the 2017 IFA trade show, it gives the option to have the Phantom 4 Pro painted in obsidian black. It June 2017 it was priced in line with the original Phantom 4. Designed to replace the original Phantom 4, the Phantom 4 Advanced uses the 2.4 GHz frequency band, the rear vision sensors and two infrared sensors in the FlightAutonomy system in comparison to the Phantom 4 Pro model. Phantom 4 Advanced Īnnounced on April 13, 2017, the Phantom 4 Advanced uses the same camera sensor as the Phantom 4 Pro. In addition - DJI released a set of Goggles, which can be used with various DJI equipment, including the Phantom 4 Pro, to allow for First Person View (FPV) flying. It integrates an upgraded Lightbridge HD video transmission system that adds 5.8 GHz transmission support and a maximum downlink video transmission range of 7 km. The Phantom 4 Pro offers two remote controllers, one with a dedicated screen (Phantom 4 Pro+) and one without. It upgrades its obstacle avoidance with five directional sensors. Motor: 920 Kv, Configuration 12N/14P, Maximum Output Power 140 W, size 28x24 mm, weight 50g ĭJI Phantom 4 Pro, released in November 2016, has a three-axis stabilized camera with a 1-inch (25 mm) 20 MP CMOS sensor FC6310.These are the specs for the Vision+ model: So, I decided to take another path, re-enabling the Telnet service.The DJI Phantom drones have mostly similar technical properties. Root access to the aircraft is something hard to achieve because the root password is strong, I tried to crack it but it resists to some days of cracking (thanks to the Hacktive Security’s guys) The drone underlying system is a fork of OpenWRT 14.07 “ Barrier Breaker, r2879, 14.07” built for “ ar71xx/generic“, same version for the controller. I tried to replace the firmware with a modified version but the firmware is signed and resilient to tampering.ĭowngrading the firmware to its precedent version ( V) result in an unrestricted root FTP access, so, I dumped the file system and started diving into it. Unfortunately, on the latest firmware ( V), the root ftp access to the drone is chrooted and I wasn’t able to escape the /tmp directory, plus, Telnet and SSH access are disabled. While the first file contains the root password for the FTP access to every device inside the network, the second file contains some areas where the drone cannot fly (no-fly zones/virtual fence) like: airports, stadiums, military bases, cities, etc. Since I didn’t have any passwords for these services I decided to give a look at the Android App (DJI GO) and surprisingly, I found these details while reversing it: How you can see from the above scan, some services draw my attention: |_drwxr-r- 2 0 0 0 System Volume InformationĢ2/tcp open ssh syn-ack OpenSSH 6.2 (protocol 2.0)Ģ3/tcp open telnet syn-ack BusyBox telnetd | ftp-anon: Anonymous FTP login allowed (FTP code 230) Here the nmap result for every device: Nmap scan report for 192.168.1.1Ģ345/tcp open landesk-rc syn-ack LANDesk remote managementĢ1/tcp open ftp syn-ack BusyBox ftpd (D-Link DCS-932L IP-Cam camera) Interestingly, the camera is separated from the aircraft, I suppose because in that way, image feedback won’t interfere with the aircraft navigation. Inside the network, I was able to find out these IP addresses: The default associated password is: 12341234 Wi-Fi encryption is WPA2 and the default SSID is derived from the MAC address of the remote controller: PHANTOM3_. ![]() The Phantom 3 comes with an aircraft, controller and an Android/iOS app.Īs a first step, I have analysed the protocols, the connection between the aircraft and the controller is done with Wi-Fi 5.725GHz – 5.825GHz (and not the Lightbridge protocol, for long range), while the connection between controller and mobile device is operating at 2.400GHz-2.483GHz, the controller is acting like an AP. It was my first time that I operate with drones or similar embedded system and at the beginning I didn’t have any clue about how I could interact with it. Finally, during Christmas time, I had some spare time to play with my flying beast I’m speaking about trying to hack my DJI Phantom 3.
