  • Tokenvator Release 3 Written by Alexander Polce Leary | July 22, 2021 Tokenvator Release 3 Is a Long Overdue Update That Includes a Major Overhaul to the Tool
    Tokenvator Release 3 written by Alexander Polce Leary | July 22, 2021 Tokenvator Release 3 is a long overdue update that includes a major overhaul to the tool. From the user interface, it will be mostly familiar with some command line tweaks. Under the surface, large portions of the code base have been reworked, and parts of the base have had some updates. In this series, we will go over some of the changes and new features added. Teaser Alert: Adding Privileges & Creating Tokens Improvements First and foremost, the user interface. Historically, every action had a series of positional arguments that were clunky and generally difficult to remember. They were also not very flexible, and as the commands started to have more, and additional optional arguments, they became completely unwieldy. These have been replaced with flags that will auto complete. For instance, to list and enable privileges: This also works in the non-interactive mode (though it won’t tab complete – sorry, it’s Windows): Additionally, the scroll back function was improved and numerous bugs were resolved. For instance, now when you press up you will always go to the last command issued. A printable command history has also been added if you want to copy and paste instead or keep a log of your actions. The info functionality was improved again, removing many bugs and adding additional information, such as impersonation contexts: (Tokens) > whoami [*] Operating as NT AUTHORITY\SYSTEM (Tokens) > info [*] Primary Token [+] User: S-1-5-21-258464558-1780981397-2849438727-1001

  • Process Explorer Copyright © 1996-2012 Mark Russinovich Sysinternals
    Process Explorer Copyright © 1996-2012 Mark Russinovich Sysinternals - www.sysinternals.com Process Explorer is an advanced process management utility that picks up where Task Manager leaves off. It will show you detailed information about a process including its icon, command-line, full image path, memory statistics, user account, security attributes, and more. When you zoom in on a particular process you can list the DLLs it has loaded or the operating system resource handles it has open. A search capability enables you to track down a process that has a resource opened, such as a file, directory or Registry key, or to view the list of processes that have a DLL loaded. The Process Explorer display consists of two sub-windows. The top always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window, which you can close, depends on the mode that Process Explorer is in: if it is in handle mode you will see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you will see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded. The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work. You can obtain equivalent command-line tools, Handle and ListDLLs, at the Sysinternals Web site.

  • Run a Program Under Administrator Privilege
    Knowledgebase Article Run a program under Administrator privilege © Copyright 2001-2012 EMCO Software Company web site: emcosoftware.com Support telephone: +44 20 3287-7651 Support email: [email protected] +1 646 233-1163 Knowledgebase Article Run a program under Administrator privilege 2 Run a program under Administrator privilege In this tutorial we will show you how to execute a program under another user rights to gain more access if you don't have it from your current user logon. Some of our programs require Administrator rights to the remote computer to perform correctly, and the most common support questions we get are because the user that is using our product's does not have the required privilege needed for the program to perform the way it should be!. About the RunAs feature The RunAs feature allows you to run any program under another user account rights. Think about it... if you are not a full member of the Administrator group on the computer you are logged into and have a need to run a program as the administrator user you can use the RunAs feature any time you want. But of course you need to know the password for the administrator or the user you want to use for the RunAs function. There are many ways to use and access the RunAs feature, and we will write about two of them here in this short tutorial. emcosoftware.com © Copyright 2001-2012 EMCO Software Knowledgebase Article Run a program under Administrator privilege 3 Using RunAs from the command line, Cmd.exe From the screenshot below you can see how we access this feature easily by writing just the RunAs.exe as the filename into the Cmd.exe dialog.

  • Lazarus Under the Hood Kaspersky Lab Global Research and Analysis Team Executive Summary
    Lazarus Under The Hood Kaspersky Lab Global Research and Analysis Team Executive Summary The Lazarus Group’s activity spans multiple years, going back as far as 2009. Its malware has been found in many serious cyberattacks, such as the massive data leak and file wiper attack on Sony Pictures Entertainment in 2014; the cyberespionage campaign in South Korea, dubbed Operation Troy, in 2013; and Operation DarkSeoul, which attacked South Korean media and financial companies in 2013. There have been several attempts to attribute one of the biggest cyberheists, in Bangladesh in 2016, to Lazarus Group. Researchers discovered a similarity between the backdoor used in Bangladesh and code in one of the Lazarus wiper tools. This was the first attempt to link the attack back to Lazarus. However, as new facts emerged in the media, claiming that there were at least three independent attackers in Bangladesh, any certainty about who exactly attacked the SWIFT systems, and was behind one of the biggest ever bank heists in history, vanished. The only thing that was certain was that Lazarus malware was used in Bangladesh. However, considering that we had previously found Lazarus in dozens of different countries, including multiple infections in Bangladesh, this was not very convincing evidence and many security researchers expressed skepticism abound this attribution link. This paper is the result of forensic investigations by Kaspersky Lab at banks in two countries far apart. It reveals new modules used by Lazarus group and strongly links the SWIFT system attacking tools to the Lazarus Group’s arsenal of lateral movement tools. Considering that Lazarus Group is still active in various cyberespionage and cybersabotage activities, we have segregated its subdivision focusing on attacks on banks and financial manipulations into a separate group which we call Bluenoroff (after one of the tools they used).

  • Equest MSI Package Installation Procedures For
    eQUEST MSI Package Installation Procedures For Non-Administrator and Windows Home Users eQUEST must be installed while logged in as the user who is to use the application. The Windows security system prevents non-administrative users from installing applications into the “Program Files” directory [or “Programs Files (x86)” on 64-bit Windows versions] unless an administrator elevates permissions of the installation process. Below is described the process by which the eQUEST 3.65 MSI install process can be given the required elevated permissions. 1. Opening a command prompt window from the start menu: AllPrograms\Accessories\CommandPrompt 2. Execute the following command in the command prompt window: runas /user:domain\adminUserName "msiexec /i PathAndFilenameOfMSI" 3. You will now be prompted to enter the administrator password and if the password and all the runas command parameters were are valid the installation will proceed. To find the current domain and username type “whoami” at the command prompt. However this would need to be used by the administrative user logged into their own account to obtain the required information. For Windows Home users this may be their own account. For example, on Windows 7 computer, while logged in as a non-admin user, opening a command prompt window and typing in the line below will start the installation of the eQUEST (where "W7PC" is the domain name and "JohnDOE2" is the administrator user name). runas /user:W7PC\JohnDOE2 "msiexec /i C:\ eQUEST_3_65_b7158_2013-11-03.msi" Non administrator users who wish to install eQUEST on Windows 8 simply need to double click on the MSI file and then enter the administrator password when prompted by the pop-up dialog window.
