replaced/injected PEs, shellcodes, hooks, and other in-memory patches.
Detects inline hooks, Process Hollowing, Process Doppelgänging, Reflective DLL Injection, etc.
PE-sieve is meant to be a light-weight engine dedicated to scan a single process at the time. It can be built as an EXE or as a DLL. The DLL version exposes a simple API and can be easily integrated with other applications.
Kill processes
ZwTerminateProcess is simply called from kernel land to terminate any process. Additionally, you can bury a process to avoid it to restart by setting a kernel callback to process creation: If the target process is created, Banshee will set the CreationStatus of the target process to STATUS_ACCESS_DENIED.
Change protection levels
This is done by modifying the EPROCESS structure, which is an kernel object that describes a processes attributes. It also holds a value that specifies the protection level of the process.
We can directly modify this value (aka Direct Kernel Object Modification or DKOM), since we are operating in Ring 0.
Elevate any process token to SYSTEM
EPROCESS also holds a pointer to the current access token, so we can just make it point to e.g. the token of process 4 (SYSTEM) to elevate any process to SYSTEM
Enumerating and erasing kernel callbacks
For now, only Process- and Thread-Creation kernel callbacks are enumerated, by parsing the PsSetCreateNotifyProcess/ThreadRoutine routine to reach the private Psp* routine and then parsing the address of the array, where kernel callbacks are stored.
Protecting the driver file
By hooking the NTFS filesystem's IRP_MJ_CREATE handler, we can block any process from opening a handle to our driver file
Hide Process by PID
Again, EPROCESS comes to help here - it contains a LIST_ENTRY of a doubly linked list called ActiveProcessLink which is queried by Windows to enumerate running processes. If we simply unlink an entry here, we can hide our process from tools like Process Monitor or Task Manager.

Initial operations
در ابتدا، برای انجام این روش، نیاز به دو دامنه و سرور، و همچنین یک حساب Cloudflare داریم. Evilginx را روی Apache نصب کرده و از Let's Encrypt برای فعال سازی SSL استفاده می‌کنیم. سپس سایت را به Cloudflare اضافه می‌کنیم.
با فعال کردن ویژگی Temporary Protections و تنظیم شدت آن به حالت Under Attack ، می‌توانیم سایت خود را در برابر حملات مخرب محافظت کنیم. همچنین با فعال کردن ویژگی Geo-blocking، قادر خواهیم بود دسترسی ابزارهای اسکنر و scraper را قطع کنیم. همچنین، با فعال کردن ویژگی Botfight نیز می‌توانیم در برابر حملات رباتیکی که به سایت انجام می‌شوند، محافظت کنیم.
با استفاده از ویژگی Meta Refresh، دو دامنه را در اختیار داریم. یکی Evilginx و دیگری Apache. با استفاده از این روش، می‌توانیم در صورت بازدید از Evilginx، کاربر را به Apache منتقل کنیم و Meta Data را نشان دهیم. با این کار، اسکنر ها با Apache برخورد خواهند کرد.
و در نهایت، از Obfuscation برای مخفی‌سازی کدهای HTML و JS استفاده کنید تا خوانایی آن‌ها به سادگی امکان‌پذیر نباشد.
GraphStrike supports almost all normal Cobalt Strike activities to include:
Use of Proxychains through a Cobalt Strike SOCKS proxy (though it is very slow...)
Upload/Download of large files
BOFs, execute-assembly, etc.
This also includes GraphStrike integration of the sleep, exit, and remove commands to match GraphStrike Server sleep times with Beacon as well as delete files in SharePoint when a Beacon is exited or removed.
GraphStrike additionally incorporates all of the features and functionality of the original AceLdr, with some additional API's made to utilize call stack spoofing as well.
It consists of three separate parts:
A PowerShell script where the majority of modules are located
An HTML GUI that can leverage an access token to navigate and pillage a user's account
A simple PHP redirector for harvesting authentication codes during an OAuth flow
Main Features
Search and export email
Search and export SharePoint and OneDrive files accessible to a user
Search all Teams chats and channels visible to the user and export full conversations
Deploy malicious apps
Discover misconfigured mailboxes that are exposed
Clone security groups to carry out watering hole attacks
Find groups that can be modified directly by your user or where membership rules can be abused to gain access
Search all user attributes for specific terms
Leverage a GUI built on the Graph API to pillage a user's account
Dump conditional access policies
Dump app registrations and external apps including consent and scope to identify potentially malicious apps
Tools to complete OAuth flow during consent grant attacks
GraphRunner doesn't rely on any third-party libraries or modules
Works with Windows and Linux
Continuously refresh your token package
