Remove Search Baron virus from Mac [Jun 2021]

Personal data harvesting hidden in plain sight

Search Baron browser hijack is so pesky that it overshadows another undesirable quirk of the underlying malicious app. When running on a Mac, the virus additionally keeps tabs on the victim’s online activities by unleashing a proxy module it comes equipped with. It silently monitors what sites are visited and what search queries are entered. On top of that, the infection may zero in on sensitive credentials that the user types to log into their personal web accounts, including e-banking, email, and cloud services. It also fetches details unrelated to web surfing such as macOS version as well as the list of installed applications and security tools.

By compiling all these details, the cybercriminals behind Search Baron can form a verbose profile of the unsuspecting target and abuse this information to carry out identity theft and trustworthy-looking phishing stratagems. Chances are that the data will be sold to other threat actors, such as disreputable advertisers or high-profile hacking groups. What’s more, some of this info can be mishandled to identify weak links in the operating system version or third-party software, which is a recipe for exploiting known vulnerabilities to expand the attack surface. To check if this exploitation is underway, go to System Preferences, click Network, select Advanced, hit the Proxies tab, and examine the list of active protocols carefully. If there is a checkmark next to a suspicious-looking proxy, it means the virus has been quietly snooping on the web traffic.

Distribution tricks

The common entry point for the Search Baron virus incursion is bundling. This is a long-running hoax that lulls people into installing malicious programs. Some eye-catching and usually free apps promoted at various uncertified software portals are at the core of this scheme, making the users think they are lucky to get such a nifty tool at zero cost. However, the installation client may turn out to have extra items under the hood, although there are typically no mentions of this fact. As a result, the to-be prey goes ahead and clicks through the setup wizard’s panes, only to additionally install the potentially unwanted application. Mac users should finally learn the lesson: opt out of the default setup mode when installing freeware and check for unwelcome complementary objects. Reading the fine print can sometimes make one’s day, really.

More than a web browsing snafu

When up and running inside a Mac, the Search Baron virus gets itself added to the login items for persistence. It also alters the settings of the admin’s preferred browser, making the search provider and homepage default to searchbaron.com. Incidentally, the URL has a tail that denotes a specific malvertising sub-campaign. For instance, the string can be something like searchbaron.com/v1/hostedsearch. The adversely revamped set-ups in Safari, Chrome or Firefox will be repeatedly taking effect each time the victim tries to select the right services manually, because there is a malicious plugin configured to make those undesired changes over and over.

Aside from web surfing interference, there is an overlapping extra symptom of the Search Baron attack that gives Mac users a hard time. It’s about noxious pop-ups that say, “Your computer is low on memory”. In an ideal world, these alerts appear when a computer lacks RAM to handle all the running applications. However, malware can fake such a condition to cross-promote associated threats. The goal of these spoofed warnings is to dupe the victim into installing a scareware application that promises to fix the low memory issue for a fee. Another likely flavor of this false alarm tactic comes down to masquerading a permission to control Safari or a counterpart the victim prefers. In this situation, the phony low memory alert treacherously overlays the rogue request.

One more element of persistence is that the infection adds a new administrative profile listed under System Preferences. This dodgy entity hampers the cleanup process by enforcing specific behavior of the affected web browser, including its default settings. The malicious app is also a thorn in the side of the contaminated Mac due to its system-wide footprint. Not only does it create a handful of offensive LaunchAgents and LaunchDaemons, but it may also recurrently inject shell scripts into more “exotic” folders such as /private/tmp. It means that the repair is a matter of removing the Search Baron virus proper, including its components meant for privilege escalation and obstinacy effects on the Mac, and then re-adjusting the affected web browser. The walkthroughs below cover what needs to be done.

Search Baron redirect virus manual removal for Mac

The steps listed below will walk you through the removal of this malicious application. Be sure to follow the instructions in the specified order.

1. Expand the Go menu in your Mac’s Finder bar and select Utilities as shown below.

   

2. Locate the Activity Monitor icon on the Utilities screen and double-click on it.

   

3. In the Activity Monitor app, look for a process that appears suspicious. To narrow down your search, focus on unfamiliar resource-intensive entries on the list. Keep in mind that its name isn’t necessarily related to the way the threat is manifesting itself, so you’ll need to trust your own judgement. If you pinpoint the culprit, select it and click on the Stop icon in the upper left-hand corner of the screen.

   

4. When a follow-up dialog pops up asking if you are sure you want to quit the troublemaking process, select the Force Quit option.

   

5. Click on the Go menu icon in the Finder again and select Go to Folder. You can as well use the Command-Shift-G keyboard shortcut.

   

6. Type /Library/LaunchAgents in the folder search dialog and click on the Go button.

   

7. Examine the contents of the LaunchAgents folder for dubious-looking items. Be advised that the names of files spawned by malware may give no clear clues that they are malicious, so you should look for recently added entities that appear to deviate from the norm.

   As an illustration, here are several examples of LaunchAgents related to mainstream Mac infections: com.pcv.hlpramc.plist, com.updater.mcy.plist, com.avickUpd.plist, and com.msp.agent.plist. If you spot files that don’t belong on the list, go ahead and drag them to the Trash.

   

8. Use the Go to Folder lookup feature again to navigate to the folder named ~/Library/Application Support (note the tilde symbol prepended to the path).

   

9. When the Application Support directory is opened, identify recently generated suspicious folders in it and send them to the Trash. A quick tip is to look for items whose names have nothing to do with Apple products or apps you knowingly installed. A few examples of known-malicious folder names are UtilityParze, ProgressSite, and IdeaShared.

   

10. Enter ~/Library/LaunchAgents string (don’t forget to include the tilde character) in the Go to Folder search area.

    

11. The system will display LaunchAgents residing in the current user’s Home directory. Look for dodgy items related to Search Baron redirect virus (see logic highlighted in subsections above) and drag the suspects to the Trash.

    

12. Type /Library/LaunchDaemons in the Go to Folder search field.

    

13. In the LaunchDaemons path, try to pinpoint the files the malware is using for persistence. Several examples of such items cropped by Mac infections are com.pplauncher.plist, com.startup.plist, and com.ExpertModuleSearchDaemon.plist. Delete the sketchy files immediately.

    

14. Click on the Go menu icon in your Mac’s Finder and select Applications on the list.

    

15. Find the entry for an app that clearly doesn’t belong there and move it to the Trash. If this action requires your admin password for confirmation, go ahead and enter it.

    

16. Expand the Apple menu and select System Preferences.

    

    

17. Proceed to Users & Groups and click on the Login Items tab.

    

    The system will display the list of items launched when the computer is starting up. Locate the potentially unwanted app there and click on the “-” (minus) button.

    

18. Now select Profiles under System Preferences. Look for a malicious item in the left-hand sidebar. Several examples of configuration profiles created by Mac adware include TechSignalSearch, MainSearchPlatform, AdminPrefs, and Chrome Settings. Select the offending entity and click on the minus sign at the bottom to eliminate it.

    

    

    If your Mac has been infiltrated by adware, the infection will most likely continue to hold sway over your default web browser even after you remove the underlying application along with its components sprinkled around the system. Use the browser cleanup instructions below to address the remaining consequences of this attack.
