ReHIPS / Re: MS Office programs hanging

« Last post by shmu26 on September 08, 2020, 09:10:58 am »

Thanks, fixer. I don't think it's network, because even when I run it unisolated, network is blocked, but it still works just fine. So I will have to check out the other things you mentioned...

ReHIPS / Re: Copy User Data enable and then disable?

« Last post by fixer on September 08, 2020, 08:29:47 am »

Well, it took some time to respond. Shame on me

After enabling Copy User Data and if everything works fine, should we then disable it?

You're right. Once all the data is copied and everything works, you can disable it. In most cases a single start (maybe some button clicking inside the program for it to try to reach all the data is required) is enough. It's not critical to leave it enabled, but it's the best practice to disable it once you're done.

A second question concerns how to update User Data. Is it a simple matter of enabling this feature or should something more involved be done, for example deleting the appropriate ReHIPS User folder?

Isolated environments have their own settings. So basically they live their own lives. And usually it's not recommended to mix isolated and non-isolated executions of the same program. So no simple way to sync settings besides deleting and recreating isolated environment.

ReHIPS / Re: ReHIPS and Shadow Defender

« Last post by fixer on September 08, 2020, 08:22:34 am »

I took a look at Shadow Defender some time ago. Well it was pretty a long ago, so something (or a lot) changed. It uses some kind of shadowing and then reverts changes back. Implemented most likely as a filesystem filter driver and snapshooting (snapshotting?). It may be convenient, but I'm not sure about security. Confidentiality? They don't try to protect it, you can send all the data outside. Integrity? Questionable. I didn't see it trying to block driver loading and it levels the field making their driver useless. With the same level of access you can always circumvent it.

On the other hand, I didn't notice any ReHIPS incompatibilities. Though I don't see any advantages either from security point of view.

Sorry it took some time to respond.

It's really hard to diagnose things like this if we can't reproduce them. Maybe something went wrong with Office itself like it failed network login (as network is not allowed) and decided to silently exit. Or maybe ESET didn't expect Office to start from some other user.

I'd start taking a look at logs (in Windows event logs, especially Office logs, maybe other security software logs). Office or other security programs may have something in there. And I'd continue with Process Monitor looking for something failed and blocked.

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

« Last post by fixer on September 08, 2020, 08:02:16 am »

Hello, RocksoftLtd and welcome to our forum.

Thank you for your purchase. I believe I answered some of these questions in email. Sorry if it failed to reach you.

When opening Ms edge in a separete isolated desktop it seems to work well until accessing the edge settings menu. Then the system completely freezes for normal input and a alt+ctrl+del is needed to get task manager up to break out of that frozen desktop.

Thank you for your report, it should be fixed in the next version. Until then it should be OK to have it running on the main desktop. At least that's what I do with all my paranoid preferences

In most cases it then allows me to kill the process via the Rehips control centre although sometimes some process are stuck there and not terminated no matter how many times hit the X button next to the process.

ReHIPS tries to terminate processes in a nice and documented way. There are some hacks that can improve killing rate but we'd like to abstain from them. And even with these hacks there are ways for a process to become literary unkillable. It's the way Windows works, nothing we can do on our side.

The apps seem to crash/freeze and even if I manage to shut them down/terminate them via task manager the isolated desktop GUI utilitly is many times sat in the corner and wont go until a log out/ system restart. Hovering the mouse over it shows it as working.

ReHIPS desktops widget relies on processes running on a separate desktop. It allows desktops switching when there are running processes. Sometimes though programs spawn child processes that don't have windows. In this case widget is there, but will switch to an empty desktop. It'll switch back after a timeout though and if I remember correctly will eventually terminate these window-less processes.

Also the general system stability is seriously affected when using apps in isolated desktops. There are a lot more system lock ups and freezes. Especially noticed with browsers. The apps seem to crash/freeze and even if I manage to shut them down/terminate them via task manager the isolated desktop GUI utilitly is many times sat in the corner and wont go until a log out/ system restart. Hovering the mouse over it shows it as working. If isolated mode is turned off  then it seems more stable but still not great.

Thank you for your time and have a good day!

It sounds like an issue with user permissions. I suggest checking what the MS Office processes try to get access to with something like Sysinternals Process Monitor. In particular, the file operations that get an "ACCESS DENIED" result.

The MS Office programs don't visibly crash. They don't even launch at all. This only happens when isolated. Otherwise, they work fine.

Do your programs just hang and do nothing except appearing in the task manager? Or do they crash on launch with a “failed to start isolated program” message?

ReHIPS seems to cause the first problem quite often on my end (32-bit Windows 7 SP1), even with no other security solution installed, and even in Disabled mode. Programs — isolated or not — randomly hang on launch, forcing me to shut them down with a task manager. A minor inconvenience most of the time, but it makes me wary of building a huge program/library in MinGW.

Only disabling the ReHIPS service and its driver seems to circumvent that problem. Honestly, it is about the only thing that keeps me from switching from Sandboxie to ReHIPS on my desktop computer.

I have yet to encounter a program that always hangs like that though.

ReHIPS / MS Office programs hanging

« Last post by shmu26 on August 31, 2020, 08:11:28 pm »

I installed ReHIPS 2.4.0 in a Windows 7 virtual machine.
I have MS Office Standard 2016 on the VM, and the Office apps hang, they don't finish launching. This happens whether or not I use the main desktop.
AV is ESET, default settings.
I disabled Hard_Configurator, which is my other security program, but that didn't help.
