和Bomb lab一样,最后一题都是最难的。 这个Phase要求我们实现Phase3一样的功能,将cookie字符串的地址传入%rdi中。因此我们同样会遇到库函数占用栈帧的问题,所以我们的cookie字符串一样需要放到最上面。 观察到mov的机器表示都有89,通过综合Phase4的gadget farm和下面的汇编: 00000000004019d6 <add_xy>: 4019d6:...
直接运行发现遇到了段错误,顺理成章地想到我们在 phase4 中踩过的坑,栈指针没有对应十六字节,导致错误。 所以我们略微调整一下输入代码,引入一下 phase4 中就找到的无义序列地址0x402244并减少后面的一行代码,得到新的p6.txt: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ...
4 I have a buffer overflow lab I have to do for a project called The Attack Lab. I'm on phase 2 of the lab, and I have to inject code as part of my exploit string in order to make the program point to the address of the function touch2(). I've gotten to the point where ...
SolutionsAs discussed earlier, a comprehensive security monitoring process not only assists with the need to perform forensic analysis but can also be a proactive security measure capable of supplying information prior to, during, and after an attack. By providing a centralized repository for security...
3. Description of solutions VisionLabs Due to the tiny fake features of 3D face masks and the complexity to distinguish, team VisionLabs proposed a pipeline based on high-resolution face parts cropped from the original image, as shown in Fig. 1. Those par...
Device hijacking: Researchers can use many tools to investigate vulnerabilities of IoT devices and propose security solutions to prevent attackers from being able to control users’ devices. CyberSecurityUP [190] provides a non-exhaustive list of these tools which researchers could consider. View artic...
Attack detection and prevention solutions are proposed to detect security attacks to find vulnerabilities and protect the system from various attacks so that the security flaws are identified before they do real damage. In CAVs, there are mainly six types of ADPS categories, i.e., (i) fingerpri...

Cloud computing offers cost-effective IT solutions but is susceptible to security threats, particularly the Economic Denial of Sustainability (EDoS) attack. EDoS exploits cloud elasticity and the pay-per-use billing model, forcing users to incur unnecess
This document has a broad scope for securing the end to end solution for IoT solutions from the consumer devices (Embedded Device Penetration Tests from the list above), to systems which reside inside the IoT vendor perimeter or cloud provider. Securing vendor inside systems is even more importan...
