USB Spy

USB SPY usb-spy 는 WiFi 또는 Ethernet 지원 마이크로컨트롤러를 기반으로 구축된 USB 대용량 저장소 트래픽 분석기입니다. 이 보드는 디스크 이미지FAT 또는 모든 파일시스템를 대상 시스템에 가짜 USB 대용량 저장소 장치로 노출하며, 실제 저장 데이터는 WiFi 또는 Ethernet을 통해 원격 서버에서 제공됩니다. 이러한 구성 덕분에 usb-spy는 대상 시스템이 수행하는 모든 블록 접근을 가로채고 분석할 수 있습니다. 단순한 원시 블록 수준 추적 외에도 usb-spy는 파일시스템을 이해하고 각 접근된...

RecoverPy

RecoverPy 원시 파티션을 스캔하고 디스크 블록을 직접 검사하여 데이터를 복구합니다. 🎬 데모 🔎 개요 파일이 삭제되면 먼저 메타데이터가 사라집니다. 기본 디스크 블록은 재사용될 때까지 종종 그대로 남아 있습니다. RecoverPy는 원시 파티션 데이터를 직접 스캔하고 장치 전체에서 바이트 패턴을 검색합니다. 블록이 덮어쓰여지지 않았다면 삭제된 파일의 조각이 여전히 내용으로 찾을 수 있습니다. 일치하는 블록을 검사하고, 인접 블록을 탐색하며, 남아 있는 것을 간단한 방식으로 추출할 수 있습니다. 블록이 사라졌다면 복구는...

The vulnerability of the blk_mq_tag_update_depth() function in the block/blk-mq-tag.c module affects the block-level kernel support in the Linux operating system. This vulnerability allows an attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the blkmqtagupdatedepth function in the block/blk-mq-tag.c module related to Linux’s block-level kernel support involves improper disabling or release of resources. Exploiting this vulnerability can allow an attacker to compromise the confidentiality, integrity, and...

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the presence of a debug file system entry leak at the block level...

The vulnerability of the __blk_mq_update_nrHW_queues() function in the block/blk-mq-sysfs.c module, which supports the block-level kernel in the Linux operating system, allows a attacker to increase their privileges.

The vulnerability of the blkmqupdatenrhwqueues function in the block/blk-mq-sysfs.c module, which supports the block-level kernel in the Linux operating system, is related to the lack of checking the returned value. Exploiting this vulnerability could allow a remote attacker to gain elevated...

Hybrid Cryptographic Monitoring System for Side-Channel Attack Detection on PYNQ SoCs

AES-128 encryption is theoretically secure but vulnerable in practical deployments due to timing and fault injection attacks on embedded systems. This work presents a lightweight dual-detection framework combining statistical thresholding and machine learning ML for real-time anomaly detection. B...

pngcheck pr***_bu*** function has a buffer out-of-bounds read vulnerability

pngcheck is used to verify the integrity of PNG, JNG and MNG files by checking the internal 32-bit CRC, aka checksum and decompressing the image data, and it has the option to dump almost all block-level information in the image in a human-readable form. A buffer out-of-bounds read vulnerability...

Binary vulnerability in pngcheck ch***_ch***_na*** function

pngcheck is used to verify the integrity of PNG, JNG and MNG files by checking the internal 32-bit CRC, aka checksum and decompressing the image data; it can optionally dump almost all block-level information in the image in a human-readable form. A binary vulnerability exists in the pngcheck...
