Adware Prevention?

I wish I had some recommendations. The problem seems to have exploded in the last 2 months in my environment.

We use ESET in a test bed of macs so far and love it.

I wish I had a better answer for you. We also have been seeing a huge uptick in the amount of Adware installed on our systems. We make Adware Medic available in Self Service and have been instructing our users how to use it to clean their systems.

I use the restricted process to block the execution (not necessarily the installation) of some of the NuisanceWare out there like MacKeeper and TuneUpMyMac, because these are just apps that are very easy to block the execution of. For other Adware like Geneio, Downlite, VidX, and VSearch, it's harder to block said execution. I've written some EA's to look for the installation of some of this software so I at least have some idea where it's installed, but my detection methods are not complete nor foolproof, and still requires the running of Adware Medic. I wonder if Tom Reed would share his Adware Medic code with us, so I could reverse-engineer his app to create an EA or series of EAs that scan for everything in his excellent app...

The bottom line is that Adware for our platform isn't going away and the best thing we can do is continue to teach our end-users to be careful about what they install. User education is the only surefire solution.

It's getting better though. The makers of Downlite recently stepped over the arbitrary line with Apple and had their software added to the XProtect list in December. Sophos has also started to detect some of this Adware as true malware (like Geneio). If we continue to report these Adwares as malware to Apple, Sophos, and others, our tools and methods of detection will improve.

Sophos has been detecting Geneio for awhile, it's a pain because it doesn't remove it from what I can tell.

Are you guys supporting users as administrators? Except Geneio, we haven't seen any of this and wondering if that's why. Our xprotect update is off as well.

Yes, almost all of our users are admins. And most of this Adware is installed alongside (mostly) legitimate installers. Unscrupulous websites will take free software like MPlayerX and bundle it alongside their Adware installer, so the end-user gets MPlayerX but also Geneio, or Downlite, etc. Part of the user education of which I speak is teaching people to be observant and aware of the state of their system and to not install software from untrusted places. We'd have anarchy if we restricted GateKeeper to only App Store purchases, so then must deal with the consequences--Adwareapalooza.

Hey @damienbarrett do you mind posting your EA's for what you have completed? Much appreciated my friend!

I would also be interested in seeing what you've come up with for EAs @damienbarrett. Although I don't think we have a big problem with adware where I am, I'll admit that we aren't actively looking for any of this stuff. I might be surprised of what a search in our JSS would turn up, but hopefully not.
That said, I have a feeling this is one of those topics that I need to get better educated in, as there seem to be more and more of this crapware coming out all the time. Such is the result of the Mac becoming more mainstream I suppose.
It does seem like user education is the only real way to stop this stuff, but if we can at least run reports, get better detection of what is being installed, etc. we can take some actions.

Incidentally, I just downloaded the latest Adware Medic just to try it out. I'm getting an immediate NilOjbect exception error when trying to run a scan. From everything I've read here, this app works, but doesn't seem to work for me :( I guess I will report it to the developer.

Mostly, they are just searches for specific files on /. All based on the excellent work and documentation over at Tom Reed's TheSafeMac. http://www.thesafemac.com/arg-identification/

Example, for Geneio. (Remember that I'm mostly just scanning for presence of the AdWare, not to remove it; although I suppose I could begin to work on a type of automated AdWare removal tool based on AdwareMedic).

Geneio:

#!/usr/bin/bash  
[ -f /private/etc/launchd.conf ] && echo "Found" || echo "Not found"

Downlite:

#!/usr/bin/env bash 

file="/Library/LaunchDaemons/Jack.plist"

if [[ -e $file ]]; then
echo <result>yes</result>
elif [[ ! -e $file ]]; then
echo <result>no</result>
fi

I've starting blacklisting nefarious websites on our web filter to see if that helps. Found a list of some annoying websites to start with here https://sites.google.com/site/appleclubfhs/support/advice-and-articles/browser-popup-hijack-safari Better to get a Firewall block message than a frustrating YOUR LAPTOP IS ABOUT TO BLOW UP!!! message. Also hoping it prevents people installing the ad/malware in the first place.

I'd hope web filters should already block a lot of these URLs. I just submitted this list of URLs to ours (iboss) so they can update ones they had uncategorized. Better to crowd source so all of their customers benefit.

Thanks for the info guys. I do have three EA's set up to search for a few adware installs, and based on info from AdwareMedic I created some scripts that the end users can run to remove the adware. Educating the end users sounds like the best option at this point.

Based on the interest shown in this thread, I'm going to be expanding my EA's for Adware detection. @elund, will you share your scripts for removal? (Why re-invent the wheel).

I'm still learning how to write scripts, so these may need some help.

What I would like to see:

All end user installations initiate the creation of a pre-post snapshot.
List of items installed creates an index.
Auto generation of removal script.

@TSOAFTVPPC - That's a great idea.

Boom. Detecting (known) adware with an extension attribute

That's me!

I'll have to read through all of this stuff to add to my script. Nice work folks!

@adamcodega @scraig I like! Thanks for building/posting!

@elund I would like to add my thanks (to you)! I stole... uh, borrowed these and they are running nicely in our environment.

I just wrote a v1 of my own extension attribute to identify adware. Primary difference with this is that it pulls the adware signatures directly from AdwareMedic's website so it should keep itself up to date. Additionally it only imports OS so you shouldn't ever need to distribute any dependencies for it to work. I have a few more things that I need to work on to handle everything but right now this will parse 99% of what AdwareMedic does. I have not built in removal just yet.

#!/usr/bin/python
import os

user = os.popen("echo $(ls -la /dev/console | cut -d " " -f 4)").read().split("
")[0]

signatures = os.popen("curl http://www.adwaremedic.com/signatures.xml").readlines()

result = "<result>"

for line in signatures:
    if "<adware name=" in line:
        adware = line.split('"')[1]
        print "Checking for " + adware
    else:
        if "type="path"" in line and "havingContent" not in line:
            if "relativeTo=" in line:
                path = line.split("relativeTo="")[1].split(""")[0]
                if path == "home":
                    path = "/Users/" + user + "/" + line.split("</item>")[0].split(">")[1]
                    if "." in path:
                        if os.path.isfile(path) and adware not in result:
                            result = result + adware + "
"
                    else:
                        if os.path.isdir(path) and adware not in result:
                            result = result + adware + "
"
            else:
                path = line.split("</item>")[0].split(">")[1]
                if "." in path:
                    if os.path.isfile(path) and adware not in result:
                        result = result + adware + "
"
                else:
                    if os.path.isdir(path) and adware not in result:
                       result = result + adware + "
"

if result == "<result>":
    print result + "No adware detected</result>"
else:
    print result[:-1] + "</result>"

here's something that was posted in the IRC channel yesterday...

Thank you Shea for your EA and Adware-removal tool. I've just implemented pieces of it in my environment this morning. I'm opting to send my end-users to Self Service to install and run Adware Medic (as we have training around this already in place), but the EA for detection of Adware is very useful.

Edit: That'll teach me not to preview before commenting. The EA that jesseshipley wrote that checks against AdwareMedic's signatures file is even better for my environment, as we already train around our users running Adware Medic. This will help me to detect the Adware and then throw up a message to prompt them to go run Adware Medic. I'm considering using Yo for this but for now will just use jamfmessage.

Nice work on that EA @jesseshipley! I'm testing it now, and although thankfully its reporting no adware on my systems, this looks really good. I love that its using the signatures from Adware Medic's site. I'll admit I never even knew there was such a signature xml file or I might have looked into doing exactly what your EA is doing. But no sense reinventing anything. Thanks for posting it.

@scraig's post on the detection and removal process is also quite useful.

As I've said elsewhere, I don't think we have a significant problem with Adware in our environment, but I'm really looking to get ahead of this in case we start to see it become an issue, so both of your posts will be very helpful in that regard.
