Opens a new window Malware Hunting on macOS Opens a new window How Malware Persists on macOS Opens a new window Use this documentation at your own risk, but if you want to further investigate what is going on this might help. And, since your Mac is no longer supported it makes sense to keep it off the Internet except to update your third party software since you are no longer getting Apple security fixes. I would not use Time Machine to restore everything since that could restore that 'rogue' process. The nuclear option would be to nuke and pave so you have a clean install of the OS and your apps. High Sierra was the last OS supported on your model. Your Mac is no longer officially supported, and you didn't say what OS you are running. Have you run any anti-malware tools to see if it detects this as a threat? If it does not run under the new user then you could move your data over to the new user and delete the old account in its entirety which could eliminate the issue. Again, this will only serve to help understand the behavior of the process. Since this process is running as root I believe this process would continue to run regardless of the user you log in as, but it couldn't hurt to create a new standard user and see if the process runs under that user as well, with WiFi on/off. That will tell you a little more about the process' behavior. Normal processes don't behave that way.Ĭurious if you see the process running in Activity monitor when WiFi is off, or if it is running only when WiFi is on. You won’t be able to see what you type, so type slowly, but at least you get 3 goes at it.I agree it does look suspicious, particularly given that when you start to look at Activity Monitor it shuts itself down as if to hide. You don’t want to make any mistakes here…Īnd provide an Admin user name. Remove permissive admin access set by the malwareīack to Terminal for this one, and mind your typing. Security remove-trusted-cert -d /tmp/rĪnd check in Keychain Access.app by searching for ‘Comodo’ and looking for a certificate that has the fake Comodo serial number:Ĥ. If you see ‘r’ listed, then issue the following command in the Terminal window: In Terminal, search to see if the ‘r’ certificate file still exists: Thirdly, you’ll want to get rid of the fake certificate in the System keychain. If you’re not comfortable running AppleScripts, you can do it manually as shown in the screenshot below, but remember you need to go through and do the procedure for every one of your services (Ethernet, Wi-Fi, Bluetooth Pan, etc) individually. Set autoproxySERVICE to item i of services as textĭo shell script (“networksetup -setautoproxyurl ” & (quoted form of autoproxySERVICE) & autoproxyURL) with administrator privilegesĭo shell script (“networksetup -setautoproxystate ” & (quoted form of autoproxySERVICE) & ” off”) with administrator privileges Repeat with i from 2 to (count of services) Set services to paragraphs of (do shell script “networksetup -listallnetworkservices”) This script was developed primarily as part of a remedy for victims of OSX/Dok malware. Turn off the Automatic Proxy Configuration in Network System Preferences. Get the script from my pastebin (if you copy and paste from a webpage like this and the script won’t compile, get the source from pastebin). While this can be done manually, it’s a lot of clicking, especially since you must do it for all services. Victims also need to remove the sneaky proxy that’s redirecting their internet traffic from System Preferences’ Network pane. Remove the network proxy redirecting your internet traffic You might also want to remove the dead ‘AppStore.app’ login item (if it’s still there) from System Preferences | Users & Groups | Login Items.Ģ. For those of you that like to do things by hand, here’s the list of things to look for. There’s FOUR steps to removing the malware.īoth my apps, DetectX and FastTasks 2 will detect this malware, and remove the appropriate files. There’s been a lot of drama the last few days over a new malware attack on macOS. Last updated: May 10th, 2017 to include Dok.B variant.
