Recently there has been a change in the behavior when a user tries to upgrade the GP client, they are challenged with the uninstall password if configured with one. Working with Palo Alto networks TAC they identified that during the upgrade the GP client package will uninstall the old version first before it will begin to install the new package. In GP client 5.2.4 and older the upgrade would complete even if uninstall with a password or disallow was enabled. This was identified as a software issue so in clients 5.2.5 and newer the ability to upgrade the client with uninstall option set to password or disallow was disabled.

In a nutshell with the new GP clients you will need to set the client setting to allow uninstall, if you want to utilize the Global Protect client upgrade process. 


Clients 5.2.4 or older, following is the behavior:

  • If you are using GP version older than 5.2.4, the transparent upgrade should work where the user will have no interaction and they can upgrade even if the allow uninstalled is disallowed.

 

Starting with 5.2.5 or above, following is the behavior:

  • Allow User to Uninstall GlobalProtect App is set to Allow
  • Allow User to Upgrade GlobalProtect App as Allow with Prompt/Manually/Transparently. (In this case, the users will be able to upgrade transparently without any interaction and the passcode/password will not be allowed)

  • Allow User to Uninstall GlobalProtect App is set to Disallow
  • Allow User to Upgrade GlobalProtect App as Allow with Prompt/Manually/Transparently (This will be blocked)

  • Allow User to Uninstall GlobalProtect App is set to "Allow with password"
  • Allow User to Upgrade GlobalProtect App as Allow with Prompt/Manually/Transparently. ( In this case, the users will need to enter the uninstall password to complete the upgrade) 


To allow the users to upgrade without providing them a password, you would need to use following.

  • Allow User to Uninstall GlobalProtect App is set to Allow
  • Allow User to Upgrade GlobalProtect App as Allow with Prompt/Manually/Transparently.”

 

My personal recommendation is to allow the client uninstall so you can leverage the GP client upgrade process. I feel the ability to upgrade the clients to ensure functionality and security is more important than blocking them from uninstalling the client. In addition we have tested with clients that are not Admins on the local machine and they were unable to uninstall the client from the windows software manager. So that is a win...


Perhaps the client upgrade functionality can also be managed with an mdm solution or with a software management tool like SCCM. But it will take some testing to find the best process that works for your environment.




 

Experience the Magic is a tag line for the Imaginefun.net website and Minecraft server. To level set for all you folks out there like me that have heard of Minecraft but never played, Minecraft is often described as a ‘sandbox game’. This means that it’s a virtual land where users can create their worlds and experiences, using building blocks, resources discovered on the site, and their creativity, but that simple definition does not do justice for what the folks at ImagineFun have built. Masekegamer and SinxMC started the Minecraft Disneyland simulation in early 2018 and since then their team has grown to over 60 Imagineers, Developers, Builders, Managers, Park Coordinators, Cast Members, and even Tour Guides.


 My first time logging in I was super overwhelmed and amazed all at the same time. Some of the controls were not intuitive for a Minecraft noob like myself, but I will try to cover that later. The graphics and the scale are second to none. The detail of every part of the park is meticulous even down to how many times a ride cue wraps. Just walking around Disneyland was jaw-dropping, but finding out there are actual functioning rides, that was a game-changing moment. Enough talk let's discuss how to connect to the servers so you can check it out for yourself.


So first off you want to check out the site https://imaginefun.net/. Once on the site navigate to the connect link at the top of the page. They did an excellent job producing a how-to video on setting up and connecting to their Minecraft server https://imaginefun.net/connect. It was straightforward even as a Minecraft noob, but once connected that is where it got a little dicey for me. I was using a mac, but for any PC or Mac using the java Minecraft client is pretty much the same. 


Pro Tips:

  • Make sure from the Minecraft launcher you install Minecraft 12.2.2 this will give you the least buggy and smoothest experience. 
  • Join their Discord server, ImagineFun is not just a game but has become a community. They have over 21,000 members on their Discord server.  To be honest this is where I got most of my information about how to enjoy the game. The people are super nice and helpful. https://discord.gg/disneyland
  • Once you start feeling comfortable in the game check out the Support section on the discord server and start playing around with the mods and shaders to make Disneyland look even more real. 
  • You will want to sync the Monecraft account you play with to the discord account you are using. You can do this by typing /syncdiscord and following the direction on the screen.
  • Different membership levels will allow you different perks.


Commands to Start Out:

  1. / or backslash.  This command will get you into chat from chat you can invoke other commands that you will need to know. 
  2. /rp This downloads and enables the resource pack so you can see all the custom work the ImaginFun team has done to create the world.
  3. /audio from within chat, you can type the word audio this will post a link in chat that you can click on. when you click on it a window will pop up in Minecraft to launch a browser or copy the link. Either one you choose will take you to a webpage that will serve park audio specific to your gameplay. It provides the audio on rides, and the ambient music for the different lands you walk through. The audio adds an immersive aspect to the Disneyland experience.
  4. /warp This command will allow you to jump to a different land, rides, and shops throughout the park. As an example, you can type /warp fantasyland.
  5. /rides Will present you a list of open rides you can warp to. Yes, the rides go down for maintenance just like the real Disneyland.
  6. /shops This will present a list of shops you can warp to.
  7. /server This will list the active servers that are up and running. If you are trying to catch up with a friend or want to be on a less crowded server this is where you can choose what sever you want to play on. Just as an FYI when you go to a new server you will need to reconnect to a new audio session using the /audio command.
  8. /msg [player] or /pm [player] Allows you to send a message in-game to another player.
  9. /tpa [player] Allows you to teleport to another player on the same server.
  10. /trade [player]  Allows you o trade items with another player.
  11. /ignore Ignore a player obviously.
  12. /vote This allows you to vote on multiple Minecraft ranking severs and you get coins.
  13. /cointrade This command will allow you to convert your currency into different types.
  14. /sb This command was a godsend I hated the floating server status window on the right site. This command toggles that on and off.


Play Mechanics:

So this was probably one of the simplest but most frustrating things to figure out, how to get on a dang ride. To get on a ride you will need to walk up to the loading platform. On most of the platforms, they will have a timer telling you how long it will take for the ride car to spawn/show up. Once the car shows up you walk up to where you want to sit and right-click the mouse. This will get you on the ride and start the ride audio. 


If you want to get off the ride you can select the left shift button that will drop you off the ride and allow you to warp somewhere else. 


There is so much more you can do on this server, I don't want to spoil all the fun. I suggest you join the Discord server to learn more about the ever-evolving game and community. Get your Disneyland fix, save a lot of cash, and tell Covid to kick rocks.


Have fun on the Happiest Minecraft server on the Planet.

**Update June 5th, 2021** There have been some questions about Defcon in person attendance and masks, especially as Las Vegas will have officially reopened completely. Dark tangent made it clear in a post on the Defcon Forums, “If a law forces us to allow people to not wear masks we would cancel the event” , if you want to read the entire conversation check it out here. https://forum.defcon.org/node/237012/page2#post237285


Dark Tangent, the founder and organizer of Defcon, just posted in the Defcon forums that the conference going to go hybrid this year.  Here is a link to his post: https://forum.defcon.org/node/236655.  DT admittedly says things are still fluid but they wanted to put out the information to help people make the decision if they are going to go virtually or in person. Now that the Goons are going to be yelling "space it out" instead of  "squeeze it in" It's going to feel like Defcon in a parallel universe.

 

There will also be some unprecedented changes this year that I wanted to outline below. Again things might change but these where the highlights from DT's post. I will add the preregistration link on this post when they release it later this month.

  • Defcon will be held both online and in person.

  • To attend in person you are required to wear a mask and be vaccinated.

  • Defcon will have socially distance seating and tables, and the convention properties will have increased air circulation and filtering.

  • For the first time Defcon will have online pre-registration for the in-person conference. The registration platform has not been selected, but they are encouraging in person attendees to preregister by insuring they will get a physical conference badge.  DT mentions that they need hard numbers of attendees to help them with planning the event.

  • They are going to order extra badges for those who show up with cash on-site, but if they guess wrong on quantity you may getting a paper badge, and if they are at capacity you could be turned away. 

  • Defcon will be throwing only the Black and White ball, entertainment. and pool parties this year. They will not be planning or organizing smaller parties.

  • Defcon has asked everyone, villages included, to pre-record all talks. Should they have to go full virtual, they won’t have a last-minute disaster of trying to capture the talks. This way DEF CON can release talks on Twitch like last year.

  • Should you be in-person and want to give your talk live they can do that, or do Q&A, or remote Q&A. Pre-recording gives Defcon options and allows everyone to see the talks. Yes, DCTV will be happening so you can also watch in your hotel room.

     

DT also listed some of the assumptions they have been working with while trying to organize Defcon this year. 

  • Almost no international attendees will attend in-person. The quarantine times and lower vaccination rates mean it is not very realistic, so we hope they will join us on-line instead.

  • That everyone in our demographic who is capable and wants a vaccination will have gotten one by the end of June.

  • Our in-person attendance will be ¼ to ½ normal, and people will be changing their minds on whether or not to attend right up to the last minute – and that includes people organizing contests, events, and villages.

  • Not all Goons will be there in-person, and many will help out by Gooning virtually.

  • While there will be fewer attendees there will also be fewer villages, contests, and events. It should all balance out so attendees don’t fee like there are a million things to do but not enough people to do them with.

  • There will be hybrid events, where you can participate in-person as well as virtually, but doing this for every event is unfortunately too demanding for many contest and village organizers.

 

I am pretty excited that Defcon will have hybrid model this year. Defcon for me over the last almost 20 years of attendance is something I look forward to every year. Like most people your last day after the con - when your hung over, hot, and reek of cigarette smoke - you have those brief thoughts that “maybe I’ll take next year off”.  That only lasts a short time before your booking your hotel for next year. 

 

Welcome back Defcon!

 

Use Cases:

Since the COVID-19 pandemic, many companies have leveraged VDI Horizon infrastructure to accommodate their remote workers. Today remote users connect to VDI Horizon infrastructure over many different means home ISP connections, company-issued cellular devices/hotspots on multiple carriers, as well as personal devices. We have identified an issue with cellular devices traversing the ATT Wireless network connecting to VDI Horizon infrastructure.

 

The Architecture:

I wanted to simplify the VDI Horizons infrastructure discussion to just the pieces that are crucial to the issue. The relevant parts that come into play for user access to the Horizons environment is the VMWare Horizon client, hardware load balancers, and the UAG or User Access Gateway servers. 

 


The Protocols:

VDI Horizons traffic is split between primary and secondary protocols. The primary protocol used for authentication is over HTTPS or port 443. Within the ATT wireless network, this traffic is sourced from the primary enterprise PAT address. After the VMware Horizon client has authenticated and established secure communication to one of the UAG appliances, one or more secondary connections are made from the Horizon client. These secondary connections can include:

Blast Extreme display protocol (TCP 443 and UDP 8443). Note that UDP is optional with Blast.

PCoIP display protocol (TCP 4172 and UDP 4172).

The secondary Horizon protocols must be routed to the same UAG appliance and from the same client IP address that the primary Horizon protocol was authenticated from. The UAG authorizes the secondary protocols based on the authenticated user session. The UAG will only forward traffic into the corporate data center on behalf of an authenticated user.


The Symptoms:

On the ATT Wireless network when a user's Horizon client connects to a virtual IP address it is load balanced to a UAG server and the session is authenticated. The IP address of the traffic is sourced and authenticated using the device’s IP address, this is true for all networks. When the Horizon client attempts to connect to the secondary protocol the traffic destined to the secondary protocol port, UDP 8443, or TCP or UDP 4172, is routed through a proxy within the ATT network. When the traffic is routed through the ATT proxy the source IP address of that traffic is different than the original device IP that was used to authenticate the user session and the VMware UAG server rejects the traffic. In some situations, the load-balanced traffic may even be sent to a different UAG server. This seems to be true for all users on the ATT Wireless network.

 

Moving toward a solution:

The first part of solving the problem is identifying the cause, and we believe that is done. Since the IP address of the primary and secondary protocols are different, the Horizons server rejects the traffic or perhaps never sees the traffic based on load balancing and persistence settings of the load balancer. ATT network engineers have been very helpful with troubleshooting and validating that our assumptions are accurate and are currently looking at solutions to solve the issue. 

**Update** the ATT sales people that where interfacing with the ATT technical staff have informed us it is not possible to fix the issue.  They are trying to sell us a cellular router that they say can be routed over an APN to solve the issue, instead of letting the technical folks fix the issue for us and potentially everyone else on the ATT wireless network.


What would we like to see:

We would like to see the secondary protocols included in the enterprise PAT and not routed through the proxy. If this was implemented, it could fix VDI Horizons across the entire ATT Wireless environment for everyone.




So SolarStorm the SolarWinds supply chain hack... Yeah.... You might have heard about it? 

 

SolarWinds supply chain was compromised. What that means is a trojanized version of a SolarWinds  package was uploaded and distributed to their clients .  The infected package contained malware named SUNBURST, and when clients installed the infected package it also installed the malware.  The malware creates a backdoor to allow the bad actors to control the server, move laterally, and exfiltrate data. Basically what ever they want....

 

 

 Updated Solarwinds Attack Lifecycle:


What should you do now:

 

As information starts to come out and the initial freak out calms down we are learning more about the impact of these exploits, and they are pretty huge. I wanted to gather a collection of information and vendor responses in one place to try to help fellow nerds have a resource of reliable information.
