I had some Windows ATOM issues before, but this beats them easily

Posted by jpluimers on 2022/10/19

I’ve had some issues with Windows ATOM tables filling up, but nothing like this security bypass:

A new Windows code injection technique, atombombing, which bypasses current security solutions.

Stop FortiClient from auto-starting (as it uses a truckload of Windows resources, often including 2 gigabyte of memory for their logger)

Posted by jpluimers on 2021/04/16

I see lot’s of negative reactions on FortiClient, as it is very closed source, many intermittent issues, and is a product that tries to be a jack of all trades (over a couple of versions, in addition of being a proprietary VPN client, they started doing vulnerability scanning, interfering with anti-virus products, they blocked saving of passwords and allowing password managers to paste them, and I could go on).

Sometimes you have to use it in order to access a FortiGate based VPN server, so the best is to defer starting it until as late as possible.

Here are some links to get that configured correctly:

How to remember password in FortiClient VPN? – Stack Overflow

Posted by jpluimers on 2021/04/12

In [WayBack] How to remember password in FortiClient VPN? – Stack Overflow, the consensus seems to be “it varies, and usually is unreliable”.

Time to write a tool that snifs the Windows GUI and auto-enters the credentials.

That would be much like the Linux expect solution: [WayBack] Continuous run Forticlient VPN using expect. Automatically restart VPN if get disconnected or session closed. · GitHub

Forticlient “the user might login in another computer”, never found the cause

Posted by jpluimers on 2019/11/25

Could only find one reference using “the user might login in another computer” – Google Search, who also could not find out why this error happened:

When trying to log in on FortiClient, I get an error message that says, “the user might login in another computer” I assume that could mean that I’m logged in on another machine elsewhere? I could not find any information confirming that.

[WayBack] Error Message | Fortinet Technical Discussion Forums

So I reached out to Fortinet, the makers of Forticlient:

[WayBack] Jeroen Pluimers on Twitter: “@Fortinet what could cause this? Searching for the message “The user might login in another computer” did not get me any further: https://t.co/Bl4KoWJ7IB FortiClient 6.6.1.723 on MacOS High Sierra.…”
