P2P Weakness Exposes Millions of IoT Devices
peer-to-peer (P2P) communications technology built into millions of security cameras and other consumer electronics includes several critical security flaws that expose the devices to eavesdropping, credential theft and remote compromise, new research has found.
A map showing the distribution of some 2 million iLinkP2P-enabled devices that are vulnerable to eavesdropping, password theft and possibly remote compromise, according to new research.
The security flaws involve iLnkP2P, software developed by China-based Shenzhen Yunni Technology. iLnkP2p is bundled with millions of Internet of Things (IoT) devices, including security cameras and Webcams, baby monitors, smart doorbells, and digital video recorders.
iLnkP2P is designed to allow users of these devices to quickly and easily access them remotely from anywhere in the world, without having to tinker with one’s firewall: Users simply download a mobile app, scan a barcode or enter the six-digit ID stamped onto the bottom of the device, and the P2P software handles the rest.
But according to an in-depth analysis shared with KrebsOnSecurity by security researcher Paul Marrapese, iLnkP2P devices offer no authentication or encryption and can be easily enumerated, allowing potential attackers to establish a direct connection to these devices while bypassing any firewall restrictions.
Marrapese said a proof-of-concept script he built identified more than two million vulnerable devices around the globe (see map above). He found that 39 percent of the vulnerable IoT things were in China; another 19 percent are located in Europe; seven percent of them are in use in the United States.
