How to recognize fake "Apple Mac Security Center" websites

What kind of scam is "Apple Mac Security Center"?

Our researchers discovered the "Apple Mac Security Center" technical support scam while investigating suspicious websites. The deceptive page claims to be associated with Apple and alerts the visitor of threats detected on their device. The goal is to trick victims into calling a fake support line and entangling them in a complex scam.

"Apple Mac Security Center" scam overview

This scam is presented as the "Apple Mac Security Center" website. The page depicts multiple pop-up windows. The topmost pop-up states that threats have been detected on the visitor's device – hence, access has been blocked for security. This and other pop-ups on the site urge the user to call the provided helpline.

It must be emphasized that the information provided by this webpage is false, and this scam is not associated with the Mac operating system or its developer – Apple Inc.

Typically, in tech support scams, once a victim calls the scammers – they (under the pretense of being "support", "technicians", "experts", etc.) ask to access the caller's device remotely. Access is often established using legitimate remote access software. While the scammers pretend to provide technical support services, they can disable/remove genuine security tools, install fake antivirus apps, obtain sensitive data, or infiltrate malware into the system (e.g., trojans, ransomware, cryptominers, etc.).

Targeted information can include: corporate content, confidential or compromising data, account log-in credentials (e.g., emails, social networking, entertainment services, FTPs, VPNs, e-commerce, online banking, cryptowallets, etc.), personally identifiable details (e.g., ID card details, passport photos/scans, etc.), and finance-related data (e.g., bank account details, credit/debit card numbers, etc.).

The fake "services" rendered by tech support scammers tend to be exorbitantly priced. These cyber criminals usually request that the payments be made using difficult-to-trace methods (e.g., cryptocurrencies, gift cards, cash hidden in packages and shipped, etc.), thereby diminishing the chances of successful prosecution and fund retrieval by victims.

In summary, victims of scams like "Apple Mac Security Center" can experience system infections, severe privacy issues, financial losses, and identity theft.

Should you find it impossible to close a scam webpage – end the browser's process using the Activity Monitor (or Task Manager on Windows). When re-launching the browser, start a new browsing session since the previous one includes the deceptive page.

If you have allowed cyber criminals to access your device remotely – you must first disconnect it from the Internet. Afterward, remove the remote access program that the criminals used, as they might not need your consent to reconnect. Lastly, perform a full system scan with an antivirus and remove all detected threats.

Technical support scam examples

"Mac OS Firewall-Alert", "Access To This Apple Device Has Been Blocked", and "Virus Alert 027341" are merely a few of our newest articles on Mac-specific tech support scams.

The Internet is rife with deceptive and malicious content. Online scams use various lures and methods, yet regardless of how they operate, their end goal is the same – to generate revenue at victims' expense. Due to how prevalent scams are on the Web and how well-made they can be – we strongly advise vigilance when browsing.

How did I open a scam website?

The most commonly used scam promotion methods include: websites employing rogue advertising networks, intrusive ads (malvertising), spam (e.g., browser notifications, robocalls/ cold calls, SMSes, emails, DMs/PMs, social media/ forum posts, etc.), misspelled URLs (typosquatting), and adware.

How to avoid visiting scam websites?

Vigilance is crucial to online safety. Therefore, be wary of websites, ads, and communications warning of severe issues or making unbelievable promises. Pay attention to URLs and type them carefully. Do not use sites offering pirated programs/media or other questionable services (e.g., illegal streaming/downloading, Torrenting, etc.), as these webpages usually use rogue advertising networks.

Do not permit dubious pages to deliver browser notifications; instead, ignore or block their requests. Approach incoming emails and other messages with caution; do not open attachments or links found in suspect/irrelevant mail.

Download only from official/verified sources and be attentive when installing (e.g., study terms and options, use "Custom/Advanced" settings, and opt out of supplementary apps, extensions, etc.) – to prevent bundled/harmful software (like adware) from infiltrating the system.

If your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate all threats.

Mac malware removal and recovery procedure

If unfamiliar processes are running, browser searches are being redirected, fans are spinning loudly for no reason, or fake "Update Safari" prompts have appeared, your Mac is likely infected. Run a full scan with Combo Cleaner for Mac to remove the infection. The full manual procedure below covers cases where automatic removal failed, where you want to verify a scan caught everything, or where the malware has multiple persistence points across LaunchAgents, LaunchDaemons, and Configuration Profiles.

Common Mac malware behaviors

VisibleAdware injection - browser hijackers and fake search engines

The most common Mac malware. Replaces your default search engine, homepage, or new-tab page with a lookalike domain that funnels every query through ad networks before passing it to a real provider. Often arrives bundled with cracked apps, fake Flash Player updates, or "free media player" downloads (MPlayerX, NicePlayer).

HiddenLaunchAgent / LaunchDaemon persistence

The standard way Mac malware survives reboots. A small .plist file in /Library/LaunchAgents/, /Library/LaunchDaemons/, or ~/Library/LaunchAgents/ tells launchd to run the malware at every login or boot. The .plist often picks a generic-looking name like com.apple.AdobeFlash.plist or com.system.helper.plist to blend in among legitimate Apple files.

HiddenConfiguration Profile abuse

Configuration Profiles are an enterprise feature - they let an IT department enforce policy on managed Macs (homepage, DNS, certificates, password rules). Adware abuses this by silently installing a Profile that locks the browser homepage, default search, or DNS server at the OS level. Manual browser reset doesn't help - the Profile reapplies the hijack. Check System Settings → General → Device Management (or "Profiles" on older macOS).

VisibleFake update prompts (FlashPlayer.dmg variants)

"Your Flash Player is out of date" or "Update your browser to view this content." Adobe killed Flash in 2020 - any current "Flash update" prompt is malware. The Atomic macOS Stealer (AMOS) family heavily uses this trick to deliver info-stealers that grab browser passwords, keychain items, and crypto wallet seed phrases. Apple's Software Update never appears as a browser pop-up.

SymptomCryptominer CPU usage

Fans spin loudly, the Mac runs hot, battery drains fast, Activity Monitor shows a process near 100% CPU. Cryptominers run silently in the background to mint cryptocurrency for the attacker. Often delivered via cracked apps from torrent sites, browser extensions, or supply-chain compromises in legitimate Mac software.

HiddenInfo stealing - AMOS, Banshee, Cthulhu, RustDoor

Modern Mac stealer families - AMOS (Atomic macOS Stealer), Banshee, Cthulhu, and RustDoor are the most active - read browser-saved passwords, cookies, autofill data, the macOS Keychain, crypto wallet seed phrases (Exodus, Electrum, Trezor Suite, MetaMask, etc.), and Apple Notes. AMOS is the most prolific overall, distributed via fake software installers, cracked apps, and fake "Spotlight" or "ChatGPT" sites. Once data is exfiltrated, the malware often deletes itself, leaving little trace - which is why credential rotation in Step 10 is critical even after the infection appears gone.

Contain - limit the damage

~5 min

1

Disconnect from the network

⏱ 30 secNo tool needed

Click the Wi-Fi icon in the menu bar (or open Control Center) and turn Wi-Fi off. If you're on Ethernet, unplug the cable. This stops any active info-stealer or backdoor from sending data out or accepting commands. Keep the network off until you've booted into Safe Mode (next step) - you'll reconnect there briefly to download the scanner.

Why this mattersAMOS-family stealers exfiltrate browser passwords, keychain entries, and crypto wallet seeds within seconds of running. Cutting the network is the only way to stop ongoing exfiltration immediately.

2

Boot into Safe Mode and download Combo Cleaner

⏱ 5 min

macOS Safe Mode loads only Apple-trusted kernel extensions and skips most third-party LaunchAgents and user login items, so persistent Mac malware doesn't auto-run while you set up the scanner. Network access works normally in Safe Mode.

Apple Silicon (M1, M2, M3, M4)

1. Choose Apple menu → Shut Down
2. Wait until the Mac is fully off
3. Press and hold the Power button until "Loading startup options" appears
4. Select your startup disk (usually "Macintosh HD")
5. Hold Shift, then click Continue in Safe Mode
6. Log in - the menu bar will show "Safe Boot" in red

Intel-based Mac

1. Choose Apple menu → Restart
2. Immediately press and hold the Shift key as the Mac begins to boot
3. Release Shift when the login window appears
4. Log in - the menu bar will show "Safe Boot" in red

Once Safe Mode has loaded, turn Wi-Fi back on and download Combo Cleaner for Mac. Save the .dmg to your Desktop. You can disconnect Wi-Fi again before scanning if you want extra caution.

Identify - find what's hiding

~15 min

3

Inspect running processes with Activity Monitor

Tool: Activity Monitor⏱ 5 min

Open Activity Monitor (Applications → Utilities → Activity Monitor, or Cmd+Space and type "Activity Monitor"). Sort by CPU usage to spot cryptominers and runaway processes.

Click each unfamiliar process and choose View → Inspect Process (Cmd+I) to see:

• Path - anything in /private/tmp/, ~/Library/Application Support/<random-name>/, or with a generic-looking bundle ID is suspicious
• Code signing - Apple's processes are signed by "Apple" or "Software Signing." Adhoc-signed or unsigned binaries from third parties warrant investigation
• Open Files and Ports - shows what the process is touching on disk and network

Why this mattersMac malware often picks process names like "CoreServicesAgent" or "WindowServer" that look legit at a glance. The Inspect view shows the actual file path, which is what tells you it's not Apple's.

4

Map persistence with KnockKnock and inspect the launch paths

Tool: KnockKnock + Finder⏱ 7 min

Download KnockKnock by Objective-See (Patrick Wardle's free tool, the Mac equivalent of Sysinternals Autoruns). It lists every place macOS malware can persist in a single window: LaunchAgents, LaunchDaemons, Login Items, Cron Jobs, Browser Extensions, Kernel Extensions, Authorization Plug-ins, Mail Plug-ins, Quicklook, Spotlight, and more.

Run KnockKnock and toggle "Filter Signed Items" to focus on unsigned or non-Apple-signed entries. Click any suspicious item to see its file path and code-signing status.

If you'd rather check manually, open Finder → Go → Go to Folder (Shift+Cmd+G) and visit each path:

• /Library/LaunchAgents/ - system-wide, runs at login for any user
• /Library/LaunchDaemons/ - system-wide, runs at boot before login
• ~/Library/LaunchAgents/ - user-level, runs at this user's login
• ~/Library/Application Support/ - where adware drops its data folder, often with a random or app-mimicking name

Then check additional persistence locations in System Settings:

• Login Items & Extensions - System Settings → General → Login Items & Extensions. Click anything you don't recognize and remove it
• Background Items - same panel, "Allow in the Background" section. Mac malware often shows up as a background item with an obscure name
• Configuration Profiles - System Settings → General → Device Management (or "Profiles" on older macOS). Remove any Profile you didn't install yourself

Pro tipRight-click any suspicious .plist → Open With → TextEdit. The <key>Program</key> and <key>ProgramArguments</key> values tell you exactly what executable runs and from where. Don't delete yet - write down the file paths and entry names. We'll remove them after the Combo Cleaner scan in Step 7.

5

Check /etc/hosts and DNS settings

⏱ 3 minBuilt into macOS

Mac malware sometimes redirects bank, Apple, antivirus, and update domains to attacker-controlled servers via the hosts file or DNS settings.

Hosts file: Open Terminal (Applications → Utilities → Terminal) and run:

sudo nano /etc/hosts

Legitimate entries are commented with #. Any uncommented IP-to-domain mapping is suspicious - especially redirects for apple.com, icloud.com, your bank, or your password manager. Press Ctrl+X to exit nano without saving.

DNS settings: System Settings → Network → click your active connection (Wi-Fi or Ethernet) → Details → DNS. Confirm DNS servers point to your ISP, your router, or a known public resolver (Cloudflare 1.1.1.1, Google 8.8.8.8). Anything else has been hijacked.

Why this mattersA clean Mac with hijacked DNS is still a compromised Mac. You'll think you're at chase.com and you'll be at the attacker's clone.

Remove - scan and clean up

~30 min

Recommended antivirus: Combo Cleaner for MacDetects adware, info-stealers, cryptominers, and the LaunchAgent / LaunchDaemon persistence files they install. The 7-day free trial is available.

Run a full Combo Cleaner for Mac scan

Tool: Combo Cleaner⏱ 20–30 min

Open the .dmg you downloaded in Step 2. Drag the Combo Cleaner icon to the Applications folder. Open it from Launchpad (or Applications), allow it to update its threat database, then click Start Combo Scan and let it complete fully. Review what it found and apply the recommended actions.

Why this comes before manual cleanupCombo Cleaner removes known adware, info-stealers, cryptominers, and the LaunchAgent persistence files they installed in one pass. Manual cleanup in Step 7 is for anything still left over.

7

Manually remove anything still present

⏱ 10 minTool: Finder

Reopen KnockKnock (or revisit the Finder paths from Step 4). Anything you flagged that's still present hasn't been caught by the automated scan. For each remaining suspicious entry:

1. Note the executable path the .plist references (right-click the .plist → Open With → TextEdit, look at <key>Program</key>)
2. Move the .plist to Trash
3. Move the executable file at the referenced path to Trash
4. Empty the Trash

Then go to /Applications and remove any unwanted apps the malware installed. Common adware-installed app names: MPlayerX, NicePlayer, MyShopcoupon, Advanced Mac Cleaner, Mac Cleanup Pro. Drag them to Trash, then check ~/Library/Application Support/ for any folder with the same name and delete it too.

ImportantSome malware files reappear after deletion because something else on the system recreates them. If a file returns within minutes, you have a remaining persistence point KnockKnock didn't show. Re-run Combo Cleaner or proceed to a macOS reinstall (see end of guide).

Recover - restore browsers and security

~15 min

Reset browsers and clear notification permissions

⏱ 5 min

Mac adware persists in browser extensions, search engine settings, homepage, and notification permissions. Reset each browser you use:

• Safari: Safari → Settings → Extensions - uninstall anything you don't recognize. Then Safari → Settings → Search - restore your preferred default search engine. Then Safari → Settings → Websites → Notifications - remove all unfamiliar sites. For a deep reset: Safari → History → Clear History → "all history."
• Chrome: visit chrome://settings/reset → "Restore settings to their original defaults." Then chrome://settings/content/notifications and remove unfamiliar sites.
• Firefox: open about:support → Refresh Firefox. Then check Settings → Privacy & Security → Permissions → Notifications.

Review installed extensions in each browser and remove anything you don't recognize, especially extensions you didn't install yourself.

9

Re-verify Gatekeeper, FileVault, and System Integrity Protection

⏱ 10 min

Some Mac malware tries to weaken built-in security to make persistence easier. Verify each is on:

• Gatekeeper (blocks unsigned apps): System Settings → Privacy & Security → scroll to Allow applications downloaded from → confirm "App Store and identified developers" is selected (not "Anywhere"). If the malware added itself to the allow-list, the entry appears in the same panel - remove it.
• FileVault (full-disk encryption): System Settings → Privacy & Security → FileVault → confirm "FileVault is on for this disk." If it was disabled by malware, turn it back on.
• System Integrity Protection (SIP): open Terminal and run csrutil status. Output should be "System Integrity Protection status: enabled." If disabled, you'll need to reboot into Recovery Mode and run csrutil enable from there.

Then run macOS Software Update (System Settings → General → Software Update) to apply the latest security patches.

Verify & secure

~15 min + 7 days

Change passwords from a clean device

⏱ 20 min⚠ critical for AMOS family

If the malware was an info-stealer (AMOS, Banshee, Cthulhu, or RustDoor families are extremely common on Mac), assume every password saved in your browser is compromised. So is your iCloud Keychain if it was unlocked while the malware ran. Change passwords from a different, known-clean device - your iPhone is fine if it's not infected.

Recommended order:

1. Apple ID first - it controls iCloud, Find My, Apple Pay, and the App Store
2. Primary email - the recovery hub for everything else
3. Banking and financial accounts
4. Password manager master password (if you use one)
5. Crypto wallet seed phrases - if you store any seed phrase or private key on the Mac, AMOS specifically targets these. Move funds to a fresh wallet from a clean device immediately, before changing other passwords
6. Social media, shopping, and remaining accounts

Where available, enable phishing-resistant multi-factor authentication (passkeys / hardware keys / authenticator apps) - SMS-based MFA is bypassable.

11

Verify the clean and monitor for 7 days

⏱ 5 min + 1 week monitoring

Reconnect to the network and run one final full scan with Combo Cleaner. Open System Settings → General → Login Items & Extensions and confirm nothing suspicious has reappeared. Open Activity Monitor and verify no unfamiliar process is using significant CPU.

Over the next 7 days, watch for symptom recurrence: high CPU when the Mac is idle, browser redirects returning, fake update prompts, or unfamiliar Login Items reappearing. If anything returns, you missed a persistence point and the procedure needs to be repeated - or you may have a deeper compromise that requires a clean macOS reinstall.

When to reinstall macOS instead

Manual removal isn't always the right answer. Reinstalling macOS from scratch is the only way to be 100% certain when:

• The malware reappears after every removal attempt
• A kernel extension or system-level component was modified
• Confirmed credential-theft malware ran with admin rights - the system likely has multiple unknown payloads
• The Mac is used for online banking, crypto wallets, business email, or anything where partial doubt isn't acceptable

macOS reinstall is straightforward: shut down → boot to Recovery (Apple Silicon: hold the Power button → Options; Intel: Cmd+R during boot) → Erase Mac → Reinstall macOS. Back up documents to external storage first, scan the backup with Combo Cleaner before restoring it, and reinstall apps fresh - never restore them from a backup of the infected system.

Important: Manual removal of Mac malware requires care - deleting the wrong .plist or system app can prevent macOS from booting normally. If you're not confident identifying system files from malicious files, run an automated scan with Combo Cleaner for Mac and stop there - that path catches the vast majority of consumer Mac malware without the risk of breaking macOS.

Frequently Asked Questions (FAQ)

What is a pop-up scam?

Basically, pop-up scams are deceptive messages intended to trick users into performing certain actions. For example, victims can be tricked into calling fake helplines, allowing scammers to access devices remotely, downloading/installing software, purchasing products, subscribing to services, making monetary transactions, and so forth.

What is the purpose of a pop-up scam?

Pop-up scams are designed to generate revenue for scammers. Profit can be made by acquiring funds through deception, promoting content (e.g., websites, programs, products, services, etc.), selling/abusing private data, and proliferating malware.

Why do I encounter fake pop-ups?

Pop-up scams are primarily endorsed via spam (e.g., emails, browser notifications, DMs/PMs, calls, social media posts, etc.), webpages that use rogue advertising networks, intrusive advertisements, mistyped URLs, and adware.

I cannot exit a scam page, how do I close it?

If you cannot close a scam site – end the browser's process using the Activity Monitor. Remember to start a new browsing session when reopening the browser, as the previous one contains the deceptive webpage.

I have allowed cyber criminals to remotely access my computer, what should I do?

If you have allowed scammers to access your device remotely – the first step is to disconnect it from the Internet. The second is to uninstall the remote access software that the scammers used, as they might not need your permission to reconnect. The last is to run a complete system scan with an antivirus and eliminate all detected threats.

I have provided my personal information when tricked by a pop-up scam, what should I do?

If you have provided your log-in credentials – change the passwords of all potentially exposed accounts and inform their official support. However, if you've disclosed other private data (e.g., ID card details, credit card numbers, etc.) – contact the appropriate authorities without delay.

Will Combo Cleaner protect me from pop-up scams and the malware they proliferate?

Combo Cleaner is designed to detect and eliminate all kinds of threats. It can scan visited websites for deceptive/malicious content and prevent further access to such pages.
