Remove Safari virus warning scam from iPhone/Mac

Here is a hands-on summary of the Safari virus warning, a multi-pronged pivot of numerous online scams targeting Mac and iPhone users for years.

Threat actors who boil their schemes down to ensnaring users of Apple products couldn’t possibly pass by Safari, the browser pre-installed on millions of hugely popular devices. Until recently, gadgets running iOS and iPadOS hadn’t even allowed for switching to another default browser. The latest Safari version for the Mac is more visually attractive than the predecessors and delivers awesome privacy extras. While these bells and whistles are good news for the average user, they are a call to action from a seasoned attacker’s twisted perspective. Amid all the exploitation opportunities in the present-day crooks’ handbook, the Safari virus warning stands out due to its prevalence and wicked efficiency. It underlies a series of online scams whose goals run the gamut from injecting malware to stealing Apple IDs and other sensitive credentials.

Safari virus warning scams are booming across the iPhone ecosystem

An example of the attack chain on an iPhone is a Safari warning that says the device is infected with a virus and the user needs to take immediate action to take care of the alleged predicament. It is manifested as a pop-up that appears on a dubious website the user visits out of curiosity or in the aftermath of clicking a fishy link. In some scenarios, a script stealthily injected into a legitimate site is to blame for redirecting the browser to a faux alert page. When the victim taps Close, the alert may vanish for a while and then reappear, or Safari will further forward the Internet traffic to a dodgy resource that provides fraudulent cleaning recommendations. The page may promote a security app that’s spyware in disguise. It could as well instruct the user to enter their Apple ID and password in a fake form that mimics the authentic sign-in page.

Safari virus warning reports a pseudo-infection on an iPhone

One more widespread type of this hoax in the mobile context is a Safari alert stating that the iPhone is infected with 6 viruses. To pressure the user, the warning goes on to say that the infection may brick the device, damage the SIM, and wipe all contacts unless removed. As is the case with the above-mentioned attack vector, the follow-up steps will try to dupe the victim into slipping up by providing personal information or installing a rogue app that will open a backdoor into the system so that the malefactor can access it at a later point. A particularly adverse situation occurs if the scammer obtains access to the Find My service to remotely lock the device. If this trick pans out, the attacker may mishandle the custom lock screen feature to display a ransom note and extort the user.

iPhone Safari virus warning may use extra scare tactics

A spoofed warning that says, “Your iPhone Has Been Hacked” is yet another common type of the fraudulent Safari alert. It relies on a similar logic, attempting to hoodwink the would-be victim into disclosing account credentials or dialing a phone number to contact a pseudo-technician who will try to wheedle out personally identifiable information.

The Mac facet of the Safari virus warning

There are plenty of such scams with a Mac flavor, too. In a long-running tech support fraud campaign, malicious actors use landing pages that say, “Your system is infected with 3 viruses”. Unlike the previously mentioned iPhone hoaxes, the purpose of this one is restricted to contaminating a computer with a scareware application. The alert contains a “Scan Now” button that, when clicked, triggers a page mimicking a security audit of the target system and recommending a fake cleaner to address the purported infestation with malware like Tapsnake, CronDNS, or Dubfishicv. The warning page includes a logo of the AppleCare Protection Plan to give victims a false sense of legitimacy. Another prolific Mac scam saying, “Zeus Virus Detected” bears a resemblance to this one, except that it mainly tries to coerce victims into contacting impostor support agents over the phone.

‘Your system is infected with 3 viruses’ hoax

Macs are also being shelled with a variant of the Safari virus warning that promotes a booby-trapped version of the Adobe Flash Player. Although the software in question is obsolete now in 2021 and is no longer supported by the publisher, cybercriminals continue to piggyback on its past fame to spread adware and phony Mac maintenance tools. The counterfeit Flash Player update alerts pop up for one of the following reasons: if a corresponding script is triggered on a malicious or compromised website the user visits; or if a browser hijacker has previously cropped up in the system and is causing incessant redirects to untrustworthy pages that display the sketchy update recommendation.

Fake Flash Player update pop-up in Safari

If a Mac user falls for this trivial stratagem, they unknowingly permit a strain of malware to infiltrate the system. The resulting payload will install a pest such as a Safari redirect virus or an app that pretends to detect numerous performance issues and security threats. In the latter case, the user runs the risk of wasting money on a cleaning service they don’t actually need. When it comes to this hoax, a rule of thumb is to distrust software update prompts generated by a web page.

Regardless of the specific spin-off of the Safari virus warning fraud, the right response is two-fold. Ignoring what these browser-borne alerts say is half the battle. In other words, do not follow the steps listed in these dialogs or engage in any form of interaction other than closing them. Secondly, if the pop-ups or browser redirects keep occurring, this is a telltale sign of malware already running in the system. This situation won’t sort itself out unless the harmful code is purged. Depending on the affected device, the steps below should pull the plug on the unwanted browser activity.

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

    Select the Activity Monitor

  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.

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

    Open /Library/LaunchAgents folder

  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).

    Open ~/Library/Application Support folder

  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 Quick Mac Booster, IdeaShared, and ProgressMatch.

    Application Support folder contents

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

    Open ~/Library/LaunchAgents directory

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

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

    Go to /Library/LaunchDaemons

  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.

    LaunchDaemons folder contents

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

  15. Find the 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.

    Drag malicious app to the Trash

  16. Expand the Apple menu and select System Preferences.

    Select System Preferences

    Open System Preferences

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

    Proceed to Users & Groups

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

    Delete unwanted login item

  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.

    Select Profiles under System Preferences
