The Top Search Result Is an Ad, and Sometimes It Is a Scam

Someone on your team needs to install a PDF reader, or reach a supplier’s portal. They search for it, the first result appears, they click. That reflex is decades old and it used to be safe.

The first result is frequently a paid placement now, and criminals buy placements too. They bid on the same terms your staff search for, present the real company’s name and logo, and register a domain close enough that nobody reads it carefully. What follows is either a login page that forwards credentials to the attacker, or a download that installs something other than what it advertised.

The person almost never notices. They got the software they wanted, or the login page forwarded them somewhere afterward, and the day continues.

The mechanics

The practice is called malvertising. An attacker buys a search ad against a trusted term, perhaps a bank’s name, a Microsoft sign-in page, or a widely used utility. The ad renders normally, carrying legitimate branding and a plausible URL.

The click lands on a near-perfect replica. If the goal is credentials, the page prompts for a sign-in and passes what gets typed to the operator. If the goal is malware, it offers exactly the program the person went looking for, wrapped around a payload.

What makes these work is not the quality of the fake page. It is the position. The ad sits above the genuine result, so it is what the eye lands on first, and it arrives at the end of a search the user initiated themselves, which does not trip the suspicion an unsolicited email would.

Attackers have also learned to survive review, serving a clean page to the platform’s automated checks and the malicious version to everyone else. That is how a hostile ad clears moderation and stays live.

Scale

Google’s 2025 Ads Safety Report gives a sense of the volume. The company blocked or removed more than 8.3 billion policy-violating ads, suspended 24.9 million advertiser accounts, and pulled 602 million ads tied to scams. Google also noted attackers are now using AI to produce fraudulent ads faster than review can keep pace.

Researchers have documented scam placements impersonating widely used software including VLC, 7-Zip, and CCleaner, along with Google’s own products, distributing installers that carried credential-stealing malware. These are not exotic searches. They are the ones your team runs on an ordinary Tuesday.

Why this is a business problem rather than a personal one

Two everyday actions carry the risk: downloading software and signing in.

The download path ends with an information stealer running on a machine inside your network. That class of malware harvests saved browser passwords, session cookies, and authentication tokens. The token theft is the part worth understanding, because a stolen session token can let an attacker into an account without ever needing the password, which means multi-factor authentication does not necessarily stop them.

The sign-in path is more direct. Someone searches for “Microsoft 365 login,” clicks the sponsored result rather than the real one, and types working credentials into a page the attacker controls.

What to tell your team

Scroll past the sponsored block. The ads are labeled, they sit at the top, and the legitimate site is almost always the first organic result directly underneath.

Never download software from an ad. Type the vendor’s address directly, or use the organic result, and pull the installer from the official site.

Bookmark the destinations that matter. Banking, Microsoft 365, payroll, anything holding money or credentials should be reached from a saved bookmark rather than a fresh search every time. This one habit removes the exposure entirely for the accounts where it would hurt most.

Keep browsers and endpoints patched, so a malicious download has fewer ways to execute.

And say this out loud to your staff. Most people have never considered that the top result could be hostile, and awareness changes behavior here more reliably than it does for most security advice. A reputable ad blocker helps too, stripping sponsored results before anyone can click them, though it supplements the habits rather than replacing them.

If someone already clicked

Visiting the page without entering anything is low risk. Close it and move on. If credentials were typed, change that password immediately and verify MFA is active. If a file was downloaded and run, disconnect that device from the network and have it examined for information-stealing malware, because the password change alone will not help if a stealer is still resident.

Getting ahead of it

MVP Network Consulting helps businesses across Buffalo and Western New York close this gap, through DNS and web filtering that blocks the destinations these ads point to, endpoint protection that catches the payload, and a short staff briefing that sticks. Reach out if you want it handled before someone clicks.
