ReHIPS / Re: Is there a conflict with sandboxie?
« Last post by Ozone on April 10, 2020, 09:46:47 am »
Hi I don't want to create new thread. Just to inform you.

Looks like Sandboxie and Chrome issue is different. It's something Sandboxie-related and ReHIPS interference just provokes its fault. Some kind of race condition as if I make some delay after Chrome process is started it works OK. ReHIPS has nothing to do with this as process is suspended and basically does nothing. Though Sandboxie may throw some error that it failed to hook something in the process. It's quite complicated to debug Sandboxie when you don't know their internals with their complex inter-process dependencies. So I'll mark this one as not our fault :)

Sandboxie is now open-source: https://community.sophos.com/products/sandboxie/f/forum/119641/important-sandboxie-open-source-code-is-available-for-download
and someone has already uploaded it to github https://github.com/DavidXanatos/Sandboxie.

This should make it easier to debug it.

ReHIPS / Re: Ask Questions Here - ReHIPS Features & Unexpected Behaviors

If I remember correctly, by default Allow to create child processes is Allowed for Firefox. This means that child processes are created as is without ReHIPS interference. But maybe it's different for you? Could you post ReHIPS logs from Control Center main window Logs tab? They may have some clue.

ReHIPS / Re: Some issues I've had while testing the demo

3. I had to disable the virtual desktop, because it freezed/crashed repeatedly. Basically anytime one of ReHIPS's own dialogue popups appeared while being on the virtual deskop, it froze. I couldn't click any oft the buttons in the dialoge window. Pressing Ctrl+Alt+Del to get back to the regular desktop, revealed what the problem was - the button for switching the desktops became white/unresponsive. I had to kill the process manually ever time.
After disabling the virtual desktop, I hadn't any issue with freezes anymore.
Same here. I've had the issue with powerpoint and reported it in the other blogpost. Now the same bug is happening to all isolated programs. In my case Rehips' DesktopTools32.exe process was the one causing the freeze after any kind of popups (whether alerts from Rehips itself or other programs like vpn killswitch alerts)

Rehips as an anti-exe is a solid product and I love it but the isolation mechanism (specifically separate desktop) is unstable for now. hopefully the devs fix it soon, no worries!

ReHIPS / Re: Some issues I've had while testing the demo

1. Some programs won't start anymore with Sandboxie.
that is expected, i made a post about it long time ago.
Sandboxie and ReHIPS both inject  dlls in every process they sandbox, i guess that this is conflicting and prevent proprer use of both ReHIPS and Sbie.
You can't use both at same time for the same program.
To use both on your machine, at same time, without conflicts, you must decide which of Sandboxie or ReHIPS will sandbox the given application.
For example, if you have say Chrome and Firefox, you can protect FF with Sandboxie (and delete any ReHIPS rules for FF) and give Chrome to ReHIPS (and disabling sandboxie's sandbox for Chrome).

That is the reason i'm totally against stockpiling similar programs  (beginner's behavior thinking more softs = more protection), in reality it won't protect you much more (except in cleverly made setups), and without serious computing skills, this will create many issues ordinary users can't fathom.

Anyway sandboxie is almost dead, not maintained anymore (or barely), i dont even see the point of keep using it while you have ReHIPS.

2. The program "Rambox Pro" doesn't work with ReHIPS isolation. This is unrelated to Sandboxie. It just says that it was unable to start the program. Rambox is one of my most important programs and at the same time one of the programs which I would like to run only isolated.
you probably didn't give enough access to it. for some programs, deeper tweaks must me done.

Normally you can switch to between virtual and real desktop via the key combo.
sometimes what creates the freezes are from blocked processes the user is unaware or using several similar security softs at same time, like you seems to do.
You want evaluate properly a program, you use it alone first.

Question: is the "normal desktop-mode" less safe? I don't need it to be visually seperated im such a manner. If it's just that.
yes; but not so much, i only use Virtual Desktops for the most vulnerable applications or risky uses (PDFs and other Docs readers for files downloaded from the internet, etc...), if not i just use ReHIPS a la sandboxie (on the real desktop with just the colored border, more convenient).

4. When installing/uninstalling ReHIPS, any popup dialogue that's coming from the installer appears *behind* the installer window. When clicking on it, the "locked" sound plays, that occurs when you try to click a window that is locked by a dialogue box.
But there's no way to bring the dialogue box into foreground. Pressing enter to confirm whatever the dialoge box says doesn't work.
The only solution is to open Task Manager and kill the process of the dialogue box - then the install/uninstall process continues. This is highly disturbing. Now I have no idea what the dialogue box said / what the uninstaller did to my computer.
I have installed/uninstalled ReHIPS 4 times within my testing period, and this issue happened every time.
Never had this issue, and i installed/uninstalled ReHIPS hundreds of times already. Your OS setup is probably in cause.
doing a screenshot when this appears and posting it here would be helpful

5. There was a myriad of popups. For example when opening a new tab in a browser that runs within ReHIPS, the demo popup appeared about 30 times simultaneously. Sometimes even more. My fingers already started to hurt from all the clicking after some hours with the demo.
the demo is limited to 10 active processes, modern browsers run more than 20+ processes simultaneously (especially if you have lot of extensions), so that is expected it alerts you with one popup for each additional processes created...
If you use an old browser like IE or FF (before Quantum's multi-process), the problem won't appear.

ReHIPS / Re: HWID- computer activation managable in account settings after purchase?
« Last post by Umbra on March 20, 2020, 05:03:03 am »
The Offline activation is good enough, Fixer is quite fast to send an updated license key if the HWID changes. 

The only thing i would change is the demo, the limitation of 10 processes will reduce the user overall security while he waits the new key.

I would suggest the demo to give a time windows of 2-3 days with full ReHIPS capabilities, normally Fixer would already send the new key during this time.

ReHIPS / Re: Ask Questions Here - ReHIPS Features & Unexpected Behaviors
« Last post by winuser on March 17, 2020, 03:37:17 pm »
Sir, not sure but I think this is what happens:

- Firefox (or maybe any other multi-process browser) is set to run isolated in Rehips
- I set Rehips to disabled mode
- I run Firefox. Since Rehips is disabled, Firefox will run as the real user (i.e. not isolated). It creates (lets say) six processes
- I set Rehips to standard mode
- I open some more tabs in Firefox, this makes Firefox create another process (now total of seven processes)
- Rehips is now enabled and tries to isolate that new "Firefox.exe" process. Rehips "separate desktop" pops up along with an error window (mentioned in the previous post)

I wonder if anybody else has noticed this. BTW, I'm not a tech savvy, maybe you're right and it's all AV's fault

ps: Does Rehips check the state of the parent process before isolating its children? I mean if the parent is "firefox.exe" in the real user account, trying to run "firefox.exe", Rehips should be smart about it and show an alert to the user, something like:
" hey dude! you have a rule to isolate that browser, it's not isolated now and is trying to run multiple instance of itself, what would you like to do? "

Thank you for your report.
That's a hard thing to diagnose without having a way to reproduce it. Besides it may have nothing to do with ReHIPS like antivirus injected its DLL and something went wrong in it.
Is it reproducible? Any detailed step-by-step guide to reproduce it?
Thank you for your time.

ReHIPS / Re: Ask Questions Here - ReHIPS Features & Unexpected Behaviors

Hi, I don't know whether it's an unexpected behavior or not:
yesterday I disabled Rehips temporarily and installed a new antivirus. to test it, I opened Firefox normally (ie not isolated) and searched for eicar test file on google, then I noticed Rehips' state and enabled it (standard mode) and went to the website (www.eicar.org I guess) but suddenly Rehips' alternate desktop poped up causing Firefox to freeze with the following error:
The Instruction at 0x[SomeNumbersHere] referenced memory at 0x00000000. The memory could not be read. Click OK to termnate the program
pressing the ok button didn't help, it poped up again and again, so I had to kill Frefox in taskmanager
OS = Windows 7 x86
Rehips = Demo v2.4
Firefox = v74 set to run isolated in Rehips

I can't see a better alternative too right now. But fact is - if this system would apply to any software, many people would stop to use computers.
Or would stop using Windows/Apple software and start running Linux.

It has it benefits, but I still want to have a little bit of my life left for other things. Windows is not as hardcore as Linux and not as restricted as Apple. I've choosen it for over 20 years for a reason. No need to start an argument over this though. All systems have their strenghts. I use Linux live and in a VM and I even have an Apple device. (iPad + good microphone for hq outdoor audio recordings with good and inexpensive Apps, a lot of battery (8+ hours) and little hassle)
