BinAbsInspector - Vulnerability Scanner For Binaries

https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi_Vf77SEegN9hd3L-1LH__qKHmso-Umr6OXBz1Nb9B5MkgKlSLbxOrUGBdoSyZ0DxJnhNC0ObMqASuMmr2Lb0qxzOLfgOyvcwU5YxB7r1VQ5DEYyU6vDgxZbP2o-15P5cWcD5wsKYWn997GoL9V9xfeFp8Bku8UVgxlk7Z9YryxtLu66XQKeCDV-S0/w640-h358/binary.png BinAbsInspector (Binary Abstract Inspector) is a static analyzer for automated reverse engineering and scanning vulnerabilities in binaries, which is a long-term research project incubated at Keenlab. It is based on abstract interpretation with the support from Ghidra. It works on Ghidra's Pcode instead of assembly. Currently it supports binaries on x86,x64, armv7 and aarch64. Installation* Install Ghidra according to Ghidra's documentation
* Install Z3 (tested version: 4.8.15)
* Note that generally there are two parts for Z3 library: one is Java package, the other one is native library. The Java package is already included in "/lib" directory, but we suggest that you replace it with your own Java package for version compatibility.
* For Windows, download a pre-built package from here, extract the zip file and add a PATH environment variable pointing to z3-${version}-win/bin* For Linux, install with package manager is NOT recommended, there are two options:
1. You can download suitable pre-build package from here, extract the zip file and copy z3-${version}-win/bin/*.soto /usr/local/lib/2. or you can build and install z3 according to Building Z3 using make and GCC/Clang

* For MacOS, it is similar to Linux.

* Download the extension zip file from release page
* Install the extension according to Ghidra Extension Notes BuildingBuild the extension by yourself, if you want to develop a new feature, please refer to development guide.

* Install Ghidra and Z3
* Install Gradle 7.x (tested version: 7.4)
* Pull the repository
* Run gradle buildExtensionunder repository root
* The extension will be generated at dist/${GhidraVersion}_${date}_BinAbsInspector.zipUsageYou can run BinAbsInspector in headless mode, GUI mode, or with docker.

* With Ghidra headless mode. $GHIDRA_INSTALL_DIR/support/analyzeHeadless -- Ghidra project path. -- Ghidra project name. -- The argument for our analyzer, provides following options:
Parameter Description [-K KSet size limit K [-callStringK Call string maximum length K [-Z3Timeout Z3 timeout [-timeout Analysis timeout [-entry
] Entry address [-externalMap External function model config [-json]Output in json format [-disableZ3]Disable Z3 [-all]Enable all checkers [-debug]Enable debugging log output [-check "Enable specific checkers
*
With Ghidra GUI

1. Run Ghidra and import the target binary into a project
2. Analyze the binary with default settings
3. When the analysis is done, open Window -> Script Managerand find BinAbsInspector.java4. Double-click on BinAbsInspector.javaentry, set the parameters in configuration window and click OK
5. When the analysis is done, you can see the CWE reports in console window, double-click the addresses from the report can jump to corresponding address

*
With Docker

Domain Escalation: Unconstrained Delegation

IntroductionPost Windows 2000, Microsoft introduced an option where users could authenticate to one system via Kerberos and work with another system. This was made possible via delegation option. Unconstrained delegation is achieved via TGT forwarding technique which is what we’ll talk about in this article.Kerberos DelegationKerberos Delegation enables a service to impersonate a computer or user in order to engage with a second service using the user's privileges and permissions.Service Principal NameA unique name (identifier) of a service instance. SPNs are used by Kerberos authentication to associate a service instance with a service logon account. This allows a client application to request that the service authenticate an account even if the client does not have account name.Unconstrained DelegationThe feature debut initially in Windows Server 2000 but it is still there for backwards compatibility. Basically, if a user requests a service ticket for a service on a server set with unconstrained delegation, that server will extract user’s TGT and cache it in its memory for later use. Which means, server can pretend to be that user to any resource on the domain. Computers -> Trust this computer for delegation to any service.TGT extraction via Unconstrained DelegationIt is obvious that we need to run our attack on the machine that has delegation enabled. So we are assuming the attacker has compromised one such machine. Assumption 1: At[...]

The security loopholes made Microsoft introduce Constrained Delegation. You’ll read more about that in the next article. Hope you liked the article. Thanks for reading.___________________________

How to stop an IP accessing your website

Hi all,

I wasn't sure where to post this, so if someone could direct me to a more appropriate sub that would be awesome.

Long story short I run a business and have a malicious stalker who is trying to ruin me. Is there a way I can block her IP address from accessing my website? I believe I have her mobile and home IP.

I know it will not stop her using someone else device but it's a start.

Offensive Security's Learn Fundamentals subscription - (Complete) beginner friendly?

Hi all,

Noob here. Checking to see if anyone has subscribed to Offensive Security's "Learn Fundamentals" course (https://www.offensive-security.com/fundamentals/), and if so, how beginner friendly it is exactly.

I've heard that it is meant for "brushing up" on fundamental skills needed, but as I don't think I have these skills in the first place (almost a complete beginner in CyberSec) I'm wondering if the cost of a subscription would be better spent elsewhere...

Thanks a lot!
