be very successful, cheap and easy to carry out.”
See Also: Offensive Security Tool: Mimikatz In addition to the router bug, Juniper researchers observed the following known vulnerabilities being exploited to gain initial access to target devices:

* CVE-2020-29557 (DLink routers)
* CVE-2021-1497 and CVE-2021-1498 (Cisco HyperFlex)
* CVE-2021-31755 (Tenda AC11)
* CVE-2021-22502 (MicroFocus OBR)
* CVE-2021-22506 (MicroFocus AM)

In fact, the attackers have been continuously adding new exploits to its arsenal, according to the posting, and CVE-2021-20090 is unlikely to be the last.

“It is clear that threat actors keep an eye on all disclosed vulnerabilities,” researchers concluded. “Whenever an exploit PoC is published, it often takes them very little time to integrate it into their platform and launch attacks.”

To avoid compromise, users should update their firmware on the router. See Also: Hacking Stories: Andrian Lamo – The ‘homeless’ Hacker “In the case of IoT devices or home gateways, the situation is much worse as most users are not tech-savvy and even those who are do not get informed about potential vulnerabilities and patches to apply,” according to Juniper. “The only sure way to remedy this issue is to require vendors to offer zero-down-time automatic updates.”

hacking: security in practice
weirdo acted as another highschooler from my school for over an hour to get my explicit pics

hey guys i wanna start this off with no i did not send pictures. i just want help on how to get an IP address/ how to link a persons one social media to their other medias. i am a girl and this guy which i imagine is older because it seemed like so slid up on my snapchat saying he went to my school. he answered no questions about dress code or any of the school plans. he tried to get pictures out of me over a long time but im not a troglodyte so i dodged these. anyway he admitted so can someone tell me how to find the IP address!! i kinda wanna scare him for making me cry and making me uncomfy, but also let me know if this is a bad idea... also idk if IP grabbing is hacks either so

UnhookMe - An Universal Windows API Resolver And Unhooker Addressing Problem Of Invoking Unmonitored System Calls From Within Of Your Red Teams Malware
http://www.kitploit.com/2021/08/unhookme-universal-windows-api-resolver.html

In the era of intrusive AVs and EDRs that introduce hot-patches to the running processes for their enhanced optics requirements, modern adversaries must have a robust tool to slide through these watchguards. The propsed implementation of dynamic (https://www.kitploit.com/search/label/Dynamic) imports resolver that would be capable of unhooking used functions in-the-fly is yet another step towards strengthening adversary resilience efforts. The solution I'm proposing here is to switch from using linker-resolved WinAPI imports, staying visibile in compiled executable's PE headers (Import Address Table specifically) to favor fully-dynamic approach insisting on resolving imports only in a dynamic fashion. Such dynamical resolver can be equipped with unhooking logic happening in the background, without any sort of guidance from the operator's side.

Here's how UnhookMe example works: It presents us with the first MessageBoxW that is not subject for hooking Then we hook MessageBoxW prologue ourselves to make it always return 0 without displaying it's message Finally, we resolve MessageBoxW dynamically using the UnhookingImportResolver resolver, which will detect applied prologue patches and restore original bytes, effectively unhooking MessageBoxW functionality. In the meantime of popping message boxes, these are the loglines printed to console's stdout: [~] Resolved symbol kernel32.dll!CreateFileA
[~] Resolved symbol kernel32.dll!ReadProcessMemory
[~] Resolved symbol kernel32.dll!MapViewOfFile
[~] Resolved symbol kernel32.dll!VirtualProtectEx
[#] Found trampoline hook in symbol: MessageBoxW . Restored original bytes from file.
[~] Resolved symbol user32.dll!MessageBoxW

How to use it?
There are in total 5 C++ source code/header files that your solution need to include. However your main program file needs to include only two required headers, as detailed below. resolver.h - header containing most of the UnhookingImportResolver implementation and handy macrodefinitions resolver.cpp - source code with global options defined usings.h - a one big and nasty header file containing tens of using type definitions for commonly used WinAPIs PE.cpp - custom PE parser source code file PE.h - custom PE parser header file
Required headers
Your program will require only two headers being included: #include "usings.h"
#include "resolver.h"
Global options
There are couple of global options that can be changed affecting the way in which Resolver (https://www.kitploit.com/search/label/Resolver) works or reports it's activity. These are defined in the very beginning of resolver.cpp file: Resolver global options: globalQuietOption - set to true if you don't want to have any sort of output globalVerboseOption - set to true if you want to have detailed verbose output globalAntiSplicingOption - unhook resolved functions if they're hooked. globalLogFilePath - where to redirect output log lines. If empty, pick stdout. bool globalQuietOption = false;
bool globalVerboseOption = true;
bool globalAntiSplicingOption = true;

wchar_t globalLogFilePath[MAX_PATH] = L"";
Custom API type specification
In order to use Resolver a function pointer type must be first declared with using statement of strict form: using fn_FunctionName = ReturnType WINAPI (
ParamType1 paramName1,
...,
ParamTypeN paramNameN,
); This repository comes with usings.h header file containing predefined using types for tens of popular Windows APIs. The FunctionName will correspond to the WinAPI that we want to have ImportResolver resolve and that function pointer must be marked as having WINAPI call convention ( __stdcall on x86 and __fastcall on x64). The ReturnType must precede WINAPI type modifier.
Function resolution and usage
Having function pointer type defined like specified above, we will be able to use it in the following manner: RESOLVE(libraryName, FunctionName);
ReturnType output = _FunctionName(param1, ..., paramN); The macro RESOLVE takes care of instantiating ImportResolver templated object and adjust specifed library's name. Resolver introduces several more Macrodefinitions offering easy to use (https://www.kitploit.com/search/label/Easy%20To%20Use) in various circumstances constructor invocation: #define RESOLVE(mod, func) RESOLVE_PARAMETERIZED(mod, func, ::globalVerboseOption, ::globalAntiSplicingOption)
#define RESOLVE_NO_UNHOOK(mod, func) RESOLVE_PARAMETERIZED(mod, func, ::globalVerboseOption, false)

#define RESOLVE_VERBOSE_UNHOOK(mod, func) RESOLVE_PARAMETERIZED(mod, func, true, true)
#define RESOLVE_VERBOSE_NOUNHOOK(mod, func) RESOLVE_PARAMETERIZED(mod, func, true, false)

___________________________

#define RESOLVE_NOVERBOSE_UNHOOK(mod, func) RESOLVE_PARAMETERIZED(mod, func, false, true)
#define RESOLVE_NOVERBOSE_NOUNHOOK(mod, func) RESOLVE_PARAMETERIZED(mod, func, false, false) Resolver's constructor: ImportResolver( std::string dllName, std::string funcName, bool _verbose = false, bool _unhook = false, bool *_wasItHooked = nullptr ) "> template
ImportResolver(
std::string dllName,
std::string funcName,
bool _verbose = false,
bool _unhook = false,
bool *_wasItHooked = nullptr
)
How does it work?
The underlaying resolver leverages custom PE headers parser, that processes every referenced DLL module to map their exports and verify that module's PE headers integrity as well as integrity of referenced function's stub bytes. The idea is following: Firstly we issue LoadLibrary to load referenced by the user library (the one specified as first parameter for RESOLVE macro) if it could not be reached through GetModuleHandle. Then we process loaded/referenced library's PE headers, map its exports, retrieve array of exports addresses as well as compute these addresses ourselves for cross-verification. If address of a routine defined in DLL's Export Address Table doesn't correspond to what we would expect, the export is considered EAT hooked. The same goes if our Executable Import Address Table (IAT) entry for that function was altered and no longer points to the correct spot in DLL's code section - then the function is considered to be IAT hooked. Assuming no hooks were found so far, we fetch first N bytes of the function's prologue and compare them to what's in DLL's file stored in disk. If there is miscrepancy between bytes fetched from memory and from file - we consider function was inline patched (hot-patched). If the function was considered hooked - we return original export's address (the one we computed ourselves) and/or unhook the entry. If there were patch bytes in place, we'll restore them. Finally, in order to optimize resolver's performance (https://www.kitploit.com/search/label/Performance) impact - we cache all of the loaded modules imagebases and resolved functions addresses and return them from a cache (being std::map ) during subsequent hits. Among the problems such dynamically-unhooking resolver faced are the issues with traversing forwarded APIs (a DLL may contain Export thunk saying that this function is not implemented in this module, but it is in another one) - which although this implementation has support for, sometimes it brokes its traversal logic.
