Boko : Application Hijack Scanner For macOS

Boko.py is an application scanner for macOS that searches for and identifies potential dylib hijacking and weak dylib vulnerabilities for application executables, as well as scripts an application may use that have the potential to be backdoored. The tool also calls out interesting files and lists them instead of manually browsing the file system for analysis. With the active discovery function, there’s no more guess work if an executable is vulnerable to dylib hijacking!

The reason behind creating this tool was because I wanted more control over the data Dylib Hijack Scanner discovered. Most publicly available scanners stop once they discover the first case of a vulnerable dylib without expanding the rest of the rpaths. Since sometimes the first result is expanded in a non-existent file within a SIP-protected area, I wanted to get the rest of those expanded paths. Because of this, there are false positives, so the tool assigns a certainty field for each item.
CertaintyDescriptionDefiniteThe vulnerability is 100% exploitableHighIf the vulnerability is related to a main executable and rpath is 2nd in the load order, there is a good chance the vulnerability is exploitablePotentialThis is assigned to dylibs and backdoorable scripts, worth looking into but may not be exploitableLowLow chance this is exploitable because of late load order, but knowledge is power
The backbone of this tool is based off of scan.py from DylibHijack by Patrick Wardle (@synack). Usageboko.py [-h] (-r | -i | -p /path/to/app) (-A | -P | -b) [-oS outputfile | -oC outputfile | -oA outputfile] [-s] [-v] ParametersArgumentDescription-h, –helpShow this help message and exit-r, –runningCheck currently running processes-i, –installedCheck all installed applications-p /file.appCheck a specific application i.e. /Application/Safari.app-A, –activeExecutes executable binaries discovered to actively identify hijackable dylibs-P, –passivePerforms checks only by viewing file headers (Default)-b, –bothPerforms both methods of vulnerability testing-oS outputfileOutputs standard output to a .log file-oC outputfileOutputs results to a .csv file-oA outputfileOutputs results to a .csv file and standard log-s, –sipdisabledUse if SIP is disabled on the system to search typically read-only paths-v, –verboseOutput all results in verbose mode while script runs, without this only Definite certainty vulnerabilities are displayed to the console
It is recommended only to use active mode (-A) with the -pflag and selecting a specific program. Also, it’s a good idea to use -vwith -oSor -oA, unless you are only looking for definite certainty vulnerabilities.

Warning Note: It is highly discouraged to run this tool with the -iand (-A or –b) flags together. This combination will open every executable on your system for 3 seconds at a time. I do not take any responsibility for your system crashing or slowing down because you ran that. Additionally, if you have dormant malware on your system, this will execute it. I also recommend not scanning the whole /Applicationsdirectory if you have Xcode installed because it takes a very long time. Requirements* Python 3

Win-Brute-Logon : Crack Any Microsoft Windows Users Password Without Any Privilege

Win-Brute-Logon PoC is more what I would call a serious weakness in Microsoft Windows Authentication mechanism than a vulnerability.

The biggest issue is related to the lack of privilege required to perform such actions.

Indeed, from a Guest account (The most limited account on Microsoft Windows), you can crack the password of any available local users.

Find out which users exists using command : net userThis PoC is using multithreading to speed up the process and support both 32 and 64bit. UsageWordlist FileWinBruteLogon.exe -u Stdin Wordlisttype PoC Test Scenario (With a Guest Account)Tested on Windows 10

Install and configure a freshly updated Windows 10 virtual or physical machine.

In my case full Windows version was : 1909 (OS Build 18363.778)Log as administrator and lets create two different accounts : one administrator and one regular user. Both users are local.

/!\ Important notice: I used the Guest account for the demo but this PoC is not only limited to Guest account, it will work from any account / group (guest user / regular user / admin user etc…) Create a new admin usernet user darkcodersc /addnet user darkcodersc trousers(trousers is the password) net localgroup administrators darkcodersc /addCreate a regular usernet user HackMe /addnet user HackMe ozlq6qwm(ozlq6qwm is the password) Create a new Guest accountnet user GuestUser /addnet localgroup users GuestUser /deletenet localgroup guests GuestUser /addGet a WordlistIn my case both trousersand ozlq6qwmare in SecList : https://github.com/danielmiessler/SecLists/blob/master/Passwords/Common-Credentials/10k-most-common.txt Start the attackLogoff from administrator account or restart your machine and log to the Guest account.

Place the PoC executable anywhere you have access as Guest user.

Usage : WinBruteLogon.exe -v -u -vis optional, it design the verbose mode.

By default, domain name is the value designated by %USERDOMAIN%env var. You can specify a custom name with option -dCrack First User : darkcodersc(Administrator)prompt(guest)>WinBruteLogon.exe -v -u darkcodersc -w 10k-most-common.txt

[INFO] “TWorkers”(id=4948, handle=140) Thread successfully terminated.
[DONE] Done.
[INFO] Ellapsed Time : 00:00:06 Real world scenarioIf you gain access to a low privileged user, you could crack the password of a more privileged user and escalate your privilege. Mitigation (General)* Disable guest(s) account(s) if present.
* Application white-listing.
* Follow the guidelines to create and keep a password strong. Apply this to all users. Implement Security Lockout Policy (Not present by default)Open secpol.mscthen go to Account Policies> Account Lockout Policyand edit value Account lockout thresholdwith desired value from (1 to 999).

Value represent the number of possible attempt before getting locked.

/!\ LockDown Policy wont work on Administrator account. At this moment, best protection for Administrator account (if Enabled) is to setup a very complex password. Download
