![]() ![]() This isn't a sandbox escape (yet), but that sort of BSoD can be a sign that some questionably-designed code is running that could be exploited to make a sandbox escape. With regards to the sandbox being escaped, though, I have had various actions inside Virtualbox crash my entire OS before on several occasions. (Avast also uses this information to run surveys on how people use the Internet.) This works across the entire network connection as well, not just to your browser (which makes sense if you want to check over other protocols or services).Ī large caveat (aside from the privacy concern) is that in many such implementations, if the certificate for the original site doesn't exist or is expired, the antivirus program's own certificate causes the site to still appear "secure" even though your connection through the wider Internet won't be. Avast Antivirus in particular but also a number of other such tools actually install a man-in-the-middle proxy to read even your encrypted web traffic in case of viruses. ![]() That's where the interesting part happens. Part of the issue is that the VM is running on the host's hardware, yes, but as mentioned the antivirus shouldn't be able to see HTTPS traffic (if the infected site wasn't just an HTTP one). Only one button activates Xposed Framework. Download now: X8 Sandbox Advanced mode, easily control your root privileges. There's a lot of other areas of a network that have much lower hanging fruit to secure.I have actually seen this myself. About the X8 Sandbox virtual environment application, few people know it, but now you know you have basic root to use apps like GG, hack games :). If you're paranoid and your budget allows, isolate guests running untrusted applications on their own hardware.Ĭhances are unless you run a lot of untrusted software from third parties on VMs or are expecting targeted nation-state threats, your focus is in the wrong area. Your time is better spent applying any security updates for your guest, host, and firmware. ![]() Worst case, the added complexity causes a misconfiguration that reduces security. If you're able to pass VT-x through the sandbox to Virtualbox, well, why even have the sandbox there in the first place? The code from the guest is still being executed directly on the CPU, and sandbox or not, if there's an exploit, Ring 0 is still Ring 0 (or I suppose "Ring -1" in the case of a hypervisor). Most sandboxing relies at least partially on virtualization, which means that you likely can't run Virtualbox inside of it anyway (last I knew, 64 bit guests do not work at all in software mode without VT-x access). I don't think sandboxes do what you think they do. ![]()
