uh, and I think you're missing from re import match?

Oh thanks! Was going to dig out your other gists for the MacKeeper stuff. Does it install any frameworks/binaries anywhere else?

match is not a builtin or reserved, so the match above is just a temporary variable name, not re.match.

I found a few machines with these:
/Applications/SearchProtect/Data
/Applications/SearchProtect/SearchProtect.app
/Applications/SearchProtect/Uninstaller.app
/Applications/SearchProtect/takeOverSearchAssetsMac.app

I installed Genieo fresh this morning and they've changed some of the files in use. This is going to be a moving target :/

Just installed MacKeeper and it's now /Users//Library/LaunchAgents/com.mackeeper.MacKeeper.Helper.plist
Also Spigot installs a Safari extension here: /Users/
/Library/Safari/Extensions/Searchme.safariextz

Hey Shea, I found that this is still missing quite a bit of adware. I modified your version with more definitions and added a section so it will delete chrome and firefox preferences files if adware is found.
Not sure how to post the code properly so here ya go.

Look for "ProjectX" variants.

This adware seems to have a different name each time it pops up.

Apple's solution is too broad. We look at the files Apple suggests,

but then also search within to see if they are calling a known

binary file, "agent.app/Contents/MacOS/agent".

projectx_files = {
'/Library/LaunchAgents/com..agent.plist',

.helper.plist',

    obfuscated_name = re.search(agent_regex, launchd_job).group(1)
    found_malware.add('/Library/Application Support/%s' % obfuscated_name)

Is this an EA or a script execution (Casper scripts always have 3

args, so we can't just use the first argument.

if len(sys.argv) == 1:
# Extension attribute (First arg is always script name).
result = ''
if found_malware:

Just for the record I want to state that the above contributions include software not considered malware or adware, but just undesirable to admins in an enterprise environment.
