Is a reflected xss attack a real vulnerability?

I'm novice to web security and trying to figure out some things. I stumbled upon xss vulnerabilities and checked the reflected xss. This made me wonder if this is a real threat for a site, as I haven't found any way to efficiently exploit it.

Friend claims his iphone was controlled by someone

A friend of mine called me (from a different phone than his own) claiming he just had witnessed his iphone doing crazy things on its own. It was apparently opening apps and trying to login to stuff and all kinds of weird stuff. He told me that he could only watch it happen and couldn’t even power off the phone. Apparently he he saw a mouse cursor navigating the home screen too.

Is this even possible?

This is a long shot...

I'm desperate to recover this old YouTube video and willing to put up a reward. It's been deleted and shouldn't really have been posted anywhere else, possibly Facebook. Just delete this post if I broke the rules or anything sorry.

Is it possible to find a site that changed its URL if you know the old one?

I don't know if this is the right place to ask this but I'm curious if it's possible to find a site that had a previous URL but they changed it or is that not possible? Assuming you know nothing else but the old URL.

NtProtectVirtualMemory endp Hooks detection Userland hooks have the "weakness" to be located in userland memory, which means they are directly observable and modifiable by the process under scrutiny. To automatically detect hooks in the process address space, the main idea is to compare the differences between the original DLL on disk and the library residing in memory, that has been potentially altered by an EDR. To perform this comparison, the following steps are followed by EDRSandblast: The list of all loaded DLLs is enumerated thanks to the InLoadOrderModuleList located int the PEB (to avoid calling any API that could be monitored and suspicious) For each loaded DLL, its content on disk is read and its headers parsed. The corresponding library, residing in memory, is also parsed to identify sections, exports, etc. Relocations of the DLL are parsed and applied, by taking the base address of the corresponding loaded library into account. This allows the content of both the in-memory library and DLL originating from disk to have the exact same content (on sections where relocations are applied), and thus making the comparison reliable. Exported functions are enumerated and the first bytes of the "in-memory" and "on-disk" versions are compared. Any difference indicates an alteration that has been made after the DLL was loaded, and thus is very probably an EDR hook. Note: The process can be generalized to find differences anywhere in non-writable sections and not only at the start of exported functions, for example if EDR products start to apply hooks in the middle of function :) Thus not used by the tool, this has been implemented in findDiffsInNonWritableSections. In order to bypass the monitoring performed by these hooks, multiples techniques are possible, and each has benefits and drawbacks. Hook bypass using ... unhooking The most intuitive method to bypass the hook-based monitoring is to remove the hooks. Since the hooks are present in memory that is reachable by the process itself, to remove a hook, the process can simply: Change the permissions on the page where the hook is located (RX -> RWX or RW) Write the original bytes that are known thanks to the on-disk DLL content Change back the permissions to RX This approach is fairly simple, and can be used to remove every detected hook all at once. Performed by an offensive tool at its beginning, this allows the rest of the code to be completely unaware of the hooking mechnanism and perform normally without being monitored. However, it has two main drawbacks. The EDR is probably monitoring the use of NtProtectVirtualMemory, so using it to change the permissions of the page where the hooks have been installed is (at least conceptually) a bad idea. Also, if a thread is executed by the EDR and periodically check the integrity of the hooks, this could also trigger some detection. For implementation details, check the unhook() function's code path when unhook_method is UNHOOK_WITH_NTPROTECTVIRTUALMEMORY. Important note: for simplicity, this technique is implemented in EDRSandblast as the base technique used to showcase the other bypass techniques; each of them demonstrates how to obtain an unmonitored version of NtProtectVirtualMemory, but performs the same operation afterward (unhooking a specific hook). Hook bypass using a custom trampoline To bypass a specific hook, it is possible to simply "jump over" and execute the rest of the function as is. First, the original bytes of the monitored function, that have been overwritten by the EDR to install the hook, must be recovered from the DLL file. In our previous code example, this would be the bytes corresponding to the following instructions: mov r10, rcx
