More Mac Bitcoin Malware Being Distributed and Manual Instructions for Removing It

Bitcoin ThiefA recent trojan designed to steal your Bitcoins has expanded to apps being distributed on, according to SecureMac. The security research firm also offered manual instructions for removing the malware from your Mac if you've been infected.

The malware has been designated OSX/CoinThief.A, and it was originally distributed through apps on open source developer site GitHub called StealthBit and BitVanity. It has now been found on through apps called Bitcoin Ticker TTM, and Litecoin Ticker.

As a trojan, the malware relies on tricking the user into installing by hiding behind a seemingly legit app. SecureMac said that the above-listed "apps" were designed to look like real software found on Apple's Mac App Store.

In this case, OSX/CoinThief.A installs a browser extension in Chrome, Safari, and Firefox that "spies on Web traffic to steal Bitcoins." By watching your Web-based traffic, the app looks for Bitcoin-related logins and passwords so that the bad guys can then use those logins to steal your Bitcoins.

It then communicates with a background process called, which in turn communicates with a remote server operated by the bad guys.

SecureMac's instructions for detecting the malware:

To check for the presence of the malware on your system:

  2. Open Activity Monitor (located in your Utilities folder), and look for a process called ""
  3. Note that this is a specific name that is currently known to be used by the malware.
    Open Chrome, Safari, and Firefox (if installed on your system), and check for the presence of the "Pop-Up Blocker" extension.
  4. If you see either the "" process or the browser extensions, continue on to the removal instructions.

    • launchctl unload ~/Library/LaunchAgents/
    • Press the return key after entering the command. This command will unload the launchd task, and stop the malware from constantly running in the background If you see a message stating "No such file or directory, nothing found to unload," the launchd task was not loaded on your system.
