TL;DR: Scammers buy search ads on trusted brand names so their fake site appears above the real one. Click it and you can hand over a password or install info-stealing malware that captures saved logins and session cookies, which can get an attacker into accounts even with MFA turned on. The fix is a habit, not a product: scroll past sponsored results, bookmark the sites you log into, and never download software from an ad.
When someone on your team searches for a program to download or a site to log into, the first thing they see is usually an ad. It sits at the top, marked “Sponsored,” and most people click it without thinking twice, because the top result is normally what they wanted.
Fake search ads work because of that habit. Scammers buy ads on the names of trusted companies and popular software, so their fake page lands above the real one and gets clicked first.
The uncomfortable part is that this attack doesn’t require anyone to make a mistake. Nobody opened a suspicious attachment or replied to a stranger. Someone searched for a normal thing on Google and clicked the first result, which is exactly what search engines have trained all of us to do for twenty years.
Here’s how it works, why it fools careful people, and the handful of habits that stop nearly all of it.
How Does a Fake Search Ad Actually Work?
A scammer buys a search ad for a term people trust, like the name of your bank, a Microsoft login page, or a common program such as a PDF reader. The ad shows the real brand name and a web address that looks right. Clicking it lands you on a page built to look exactly like the real one.
The technique has a name: malvertising, short for malicious advertising.
From there it goes one of two ways. The fake page asks you to log in and sends your username and password straight to the scammer. Or it offers the software you were looking for, and the download installs malware instead of the real program.
Neither version looks wrong at the moment it happens. The page looks correct, the logo is right, and you got there from a search you started yourself.
Why Are These Ads So Easy to Fall For?
They sit above the real result, use the real company’s name, and show up on a search the person started themselves. That last part matters most. A random email or text feels like an interruption and gets a second look. A search result feels like something you went and found.
Attackers have also gotten good at hiding from the checks meant to catch them. They show a clean, harmless page to the ad review systems and the malicious page to everyone else. The ad passes review and still does damage.
This is why “just be careful” doesn’t work as a security strategy. The people who fall for this aren’t careless. They’re doing something ordinary in an ordinary way, which is exactly why security awareness training needs to cover the everyday actions, not just the obvious phishing email.
How Common Is This?
Very. Google reported that in 2025 it blocked or removed more than 8.3 billion ads and suspended 24.9 million advertiser accounts, including 602 million ads and 4 million accounts tied to scams. Google also noted that criminals are now using AI to produce deceptive ads at speed.
Read that number the right way. It isn’t proof the system is working. It’s proof of how many people are trying, and how much gets built specifically to slip through.
Security researchers keep finding these campaigns in the wild. Microsoft’s threat researchers documented ongoing campaigns where a malicious search ad sends people looking for common utilities and AI tools to fake sites that install information-stealing malware. Earlier campaigns impersonated well-known programs like 7-Zip, Notepad++, and LibreOffice.
These aren’t obscure searches. They’re the searches your team runs on a Tuesday afternoon.
What This Means for Your Business
The risk shows up in two ordinary situations: downloading software and logging in.
Someone needs a tool, searches for it, clicks the top ad, and installs something that quietly reads every password saved in their browser. Or someone searches for “Microsoft 365 login” instead of using a bookmark, clicks the ad, and types their credentials into a copy of the real page.
In both cases the payload is usually the same thing: an info-stealer. Once it’s running on a machine, it collects saved passwords, browser cookies, and session tokens.
That last item is the one business owners underestimate. A session token is proof that you already logged in successfully. An attacker who steals one can reuse it from their own computer without ever seeing a password prompt or an MFA challenge. Multi-factor authentication protects the login, and a stolen session skips the login entirely.
Verizon’s breach research found that more than half of ransomware victims had company credentials show up in info-stealer logs before the attack landed. One download on one laptop is a common first step in a chain that ends much worse. This is why managed IT services should include endpoint protection that catches the installer, not just a policy telling people to be careful.
The Newer Version: When the Ad Tells You to Paste a Command
Some of these fake pages no longer offer a download at all. Instead they display a short instruction: copy this command and paste it into Terminal, or into the Windows Run box, to verify your download or fix a problem.
It looks like a technical step, so people who consider themselves technical are the most likely to do it. Pasting that command downloads and runs the malware directly, and because nothing lands on disk as an obvious file, some security tools have a harder time catching it.
The rule to teach your team is simple. Legitimate software does not ask you to paste an encoded command into a terminal window to install it. If a page asks for that, close the page.
How Do You Protect Your Team From Fake Search Ads?
Scroll past the sponsored results. That one habit stops most of these attacks, because the ads sit at the top marked “Sponsored” or “Ad” and the real website is usually right below in the normal results. Everything else builds on that.
The habits worth teaching:
- Never download software from an ad. Type the maker’s web address yourself, or use the normal search result, then download from the official site.
- Bookmark the sites you log into. Your bank, Microsoft 365, your payroll system. Use the bookmark every time instead of searching.
- Keep devices and browsers updated. Current patches make a bad download less likely to succeed.
- Consider a reputable ad blocker or DNS filtering. Either one removes many of these links before anyone can click them. Neither is a complete fix.
- Tell your team this is a thing. Most people have no idea the top result can be a trap. Once they know, they stop clicking it.
That last one is free and it’s the most effective. Pair it with email and spam protection so the two most common delivery routes are both covered.
The Habit Is the Control
Three things to take away. The top search result is an ad, and an ad is a slot somebody bought, not a recommendation. Info-stealers can get around multi-factor authentication by stealing the session instead of the password. And the people who fall for this are doing something completely reasonable, which means blame is useless and habits are everything.
Spend five minutes on this at your next team meeting. Show people what “Sponsored” looks like on a search results page, and ask everyone to bookmark the three sites they log into most.

Frequently Asked Questions
Aren’t ads at the top of Google checked and safe?
Google reviews ads and removes billions that break its rules, but scammers still get through by showing reviewers a clean page and everyone else the malicious one. The “Sponsored” label means someone paid for that placement. It does not mean the destination is safe.
What is malvertising?
Malvertising is short for malicious advertising. Scammers buy online ads, often on trusted brand names, to send people to fake sites that steal logins or install malware. Search ads are the most common form because they intercept people who are already looking for something specific.
How do I download software safely?
Go to the maker’s official website by typing the address yourself, or use the normal non-ad search result. Don’t download from a sponsored ad, and don’t run a command a website tells you to paste into a terminal. Legitimate software never asks for that.
What should I do if someone clicked a scam ad?
If they only visited the page, close it and enter nothing. If they typed a password, change it immediately and turn on multi-factor authentication. If they downloaded or ran a file, disconnect the device from the network and have your IT provider check it for info-stealing malware and revoke active sessions.
Does an ad blocker help?
It can. A reputable ad blocker hides many sponsored results, which removes the fake links before anyone can click them. It isn’t a complete fix, since these campaigns also spread through other channels, so keep the habits above in place too.

Awareness is the cheap half of the fix. The other half is having something on the device that catches the installer when a habit slips.
