Please, help me PUA On-access detection in Sophos Linux

Any secret tip
The important question is: What is your scenario? Is this a Linux desktop and you want to be protected? Are yoi worrying that you might "pass something on"? Is this a file or web server accessed by non-Linux clients? Or a gateway?

Yes, it Linux desktop and I want to be protected.

Hello Henrique RJ,

I see. There's AFAIK nothing that's categorized as Adware or PUA for Linux. The Linux biotope is different from the ones for Windows or OS X. As there are reputable repositories for all kinds of (open and free) software you're much less likely to install a something from somewhere.
Having said that, browsing is the most likely cause for annoyance - but what could be caught by on-access scanning is mostly platform dependent and no problem on Linux.

But, Why Sophos detect phishings in Windows and not in Linux ?

Nothing ???

Any hot tip ?

oh come on people, I need one tweaking configuration for Sophos Linux to detect phishings, adwares, PUAs and miners in on-access ( the assinatures exists, it's downloaded every weeks, I look that ).

thks

Hello Henrique RJ,

why did you choose Linux as your desktop OS in the first place? No offence intended but wanting to tweak security software and being afraid of phishing does IMO not really fit together.

Actually I considere Windows 10 extremally problematic.

Look for this list in image:

The select file is a " phis-clu.ide "

It's a phishing assignature in the directory /opt/sophos-av/lib/sav/ downloaded in 27th may 2018

Why Sophos AV Linux don't detect it ( on-access ) ?

Who activate this detection in on-access ?

That is a question.

Thanks !!!

Hello Henrique RJ,

Sophos AV Linux don't detect it
doesn't detect which it? I'm not sure I understand what you expect. How can you tell what phis-clu.ide is supposed to detect? And how do you know that this detection is not activated? Do you have a sample that triggers Troj/Phish-CLU detection on Windows but not on Linux?

I tested others phishings sites ( by PhishTank ) detecteds for Sophos in VirusTotal anda in my Linux it don't detect.

Example: www.virustotal.com/

Hello Henrique RJ,

PhishTank deals with sites, On-Access scans files. As far as I can see the example site is blocked by Web Protection (which is not available on Linux) - the On-Access scanner and its detection items don't come into play here.
