![]() ![]() FuzzPD discovered 45 USBPD bugs in total, ranging from over-charging bugs to memory access violation. ![]() Guided by the dual-role state machine, FuzzPD performs multi-level mutations, not only achieving state-coverage guided mutation for inter-state exploration, but also leveraging input seeding especially for in-state mutation. FuzzPD leverages a dual-role state machine extracted from USBPD specifications. To achieve secure USBPD communications, we propose FuzzPD, the first black-box USBPD fuzzing technique. FuzzUSB has found total 34 previously-unknown bugs within the Linux and Android kernels, and demonstrated improved bug-finding efficiency with high code coverage.Īs USB Power Delievery (USBPD) is becoming prevalent, but vulnerable to cyber attacks, there is an increasing need for its security. As a stateful fuzzer, FuzzUSB extracts USB gadget state machines from USB gadget drivers, and uses them to achieve state-guided fuzzing through multi-channel inputs. To secure USB gadget stacks, we propose the first USB gadget stack fuzzing, FuzzUSB. While the security of USB host stacks has gotten lots of attention, USB gadget stacks are left behind, leaving their vulnerabilities unfixed. HFL found 24 previously unknown bugs in different Linux kernels, and achieved higher code coverage than baseline kernel fuzzers. If you're using Ubuntu, you can do this by opening a terminal and typing: sudo apt-get install libmtp After this is done, you may connect your media device on the USB, and then type: mtp-detect On the terminal. Then look for an icon representing your phone alongside other portable devices. First thing we need to do is to install libmtp which enables us to use an additional media transfer protocol for the USB ports. Click the This PC, Computer, or My Computer icon on your desktop. Furthermore, HFL addresses essential challenges in the Linux kernel via three distinct features: 1) converting indirect control transfers to direct transfers, 2) inferring system call dependencies, and 3) identifying nested arguments structures. Open the Start menu and click This PC or Computer. HFL achieves hybrid kernel fuzzing scheme with a faithful combination of traditional fuzzing and concolic execution. First, we present HFL, hybrid fuzzing for the Linux kernel. In this thesis, we aim to secure various system and embedded software, such as OS kernels, device drivers and firmware, using proposed fuzzing techniques tailored for each system software. Use the Share button, select Bluetooth to share the data, and then pick your PC in the subsequent list. Meanwhile, use your Android file browser or Gallery app to select the file you wish to transfer. While fuzzing has been proven effective for decades, recent fuzzers still suffer from limited coverage when dealing with real-world system programs, such as OS kernels, firmware due to their unique interfaces, and large input space, etc. Right-click it and select Receive a file, then click Next to commence transfer. System software is a lucrative target for cyber attacks due to its high privilege and large attack surfaces. ![]()
