Recap: Intrusion Blogs 1/2
In last month’s blog, the IoT Intrusion team hit a major roadblock with the TP-Link Kasa camera, but were able to overcome it through research into Man in the Middle Attacks. Now, armed with more knowledge than before, our team pressed on to new devices. We moved much faster this month than last. We started investigations into the intrusion of two devices, one of which we completed. These devices proved to be good subjects for investigation, but there are so many at the LCDI that we would have liked to look into. Hopefully, the end of the year does not bring the end of the project.
After our struggles with the TP-Link, the team decided to work on a different IoT security camera: the D-Link DCS 5030L. We were originally attracted to this device by a statement that the FTC put out saying that D-Link needs to increase their security in order to market themselves as offering, “advanced network security.” This gave us hope that the device might not be secure. This proved to be true, as we were able to exploit features letting users control their camera from a browser. We were able to gain access to all elements of the camera. We were able to change the password as well as view a live feed.
Malicious Intrusion OpportunityThrough this, we were able to brainstorm all the ways a malicious hacker could use this intrusion to their advantage. They could hold the device for ransom and require the owner to pay in order to regain access. An attacker could physically break into a room that had one of these cameras in it and then upon leaving erase the camera footage from the SD card. The quick success that our team had the D-Link camera allowed us to move on to another device this month.
The next device we decided to work on was the WeMo Insight Switch from Belkin. This device showed up on our radar as a potential subject back in our initial research phase of the project. A serious issue with the device was reported by Bitdefender saying that they had discovered a vulnerability that the switch leaks out wifi passwords. This was based on research done by McAfee that found a vulnerability in the UPnP ports listening on the local network in the device. Our team wants to see what we can do with this information on the device. We have it all set up and ready to test.
The Future of IoT IntrusionAlthough this may be the team’s final blog post, this is not the end of our project. We still have a few more weeks scheduled at the Leahy Center. After we attempt our intrusion on the WeMo Insight Switch, we will complete our final report. Make sure to look out for that here when it is published. As our project comes to a close, we ponder what the future may hold. We were only able to scratch the surface of this very in depth and involved line of research. That said, we hope this project laid the groundwork for future research.
