Exposed visited domains to user's ISP, potentially leaking browsing history.

Upgrade to version 12.73.0 (removes split tunneling temporarily).


Disable split tunneling or use ExpressVPN version 10.


All other traffic and content remain encrypted.

Mullvad: "Pathetic."


ProtonVPN: "This guy, right?"


Uh, I might be wrong here, but isn’t the whole purpose of split tunneling to allow you to send only necessary traffic through a given tunnel? Then the rest of your traffic goes whatever the default path is?

This seems more like a feature than a CVE. Maybe I’m missing something.


They might mean it's happening even with requests routed through the VPN.

so it would be like you say I want Firefox to go thru the tunnel, you would want the DNS requests made from it to go thru as well, in this case they weren't tunneled and were just going to the normal dns server

Well people who uses express vpn kinda deserves everything coming to them.


What's wrong with express?

There are a lot of different things, I suggest to look it up for the accurate details. However the most sketchy thing is that it's owned by Kape Technologies, previously known Crossrider *something*.. Who helped distribute malware through their frameworks. On top of that, one of the employees have had connections to the UAE, and got caught, but still works there...???

That's just the gist, and it's some crazy stuff... Any VPN owned by Kape Technologies you should stay far away from.

Edit: Source:

(yes restoreprivacy isn't a great source either, but it sums it up well enough)


Even just going off the article you posted "helped" is a strong word in regards to distributing malware through their framework. It appears that their framework had simply been hijacked by hackers to distribute malware and they had no involvement in that.

I'm not saying they're trustworthy but the situation isn't nearly as bad as this biased summary suggests.

The same website has rated express VPN as one of the most trustworthy vpns in their most recent review. Based on the high amount of independent audits the company is performing.

Definitely do more research. I'm going to look into it myself but I'm paying until June anyways and I don't think an immediate switch is necessary.


From what I know they were perfectly aware of the situation but did little about it.. So thats a red flag. But yeah, there is a lot more to this, and that one source doesn't cover it all, and is another source that shills certain VPNs themselves, hence why I said its not a great source itself. I can edit in some additional sources that are worth reading regarding the case when I get home.

But imo, there isn't a single good reason to use ExpressVPN, instead of Mullvad, IVPN or ProtonVPN.
