Covid 19 gave us a dangerous RAT Parallax , do we have a solution to block the connection if we are unsure which file is causing this issue? My few desktops are being compromised.
There is no way that normal L3/L4 firewall prevents malware from being installed on computers behind it. For that one would have to use proxy server (the non-transparrent one) which does full anti-malware (and antivirus) scan … which is not really possible to do “on the fly” while file (mail, …) is still being transferred … Well, some DPI (deep packet inspection) sollutions are aiming at performing such tasks, but DPI systems have much higher price tags than any of MT devices.
