How Cybercriminals Use Google Search to Lure Victims

A user needs software. They Google “TeamViewer download”. The first result looks official — maybe even a Google ad. But the download? It’s malware.
Cybercriminals are now using search engines like Google as delivery platforms for malware — and many businesses don’t even realise it’s happening.
Known as SEO poisoning, this technique manipulates search results — or buys ad space — to lure users to fake sites that impersonate popular tools, vendors, or support services.
In this blog, we explore how this works, what it looks like in the wild, and how organisations can protect themselves.
What Is SEO Poisoning?
SEO poisoning is the deliberate manipulation of search engine rankings to display malicious or fake pages near the top of search results.
Attackers use this to:
Impersonate popular software brands (e.g. Slack, AnyDesk, WinRAR)
Create fake documentation or support pages
Link to malicious downloads or phishing sites
This technique often goes hand-in-hand with malvertising — using paid search ads — but SEO poisoning can also succeed organically, without buying ads.
Real Examples of SEO-Based Attacks
Fake PDF and Doc Sites
Cybercriminals create pages claiming to offer PDFs, whitepapers or documentation. These rank for niche technical terms and often contain download buttons that launch malware installers.
Impersonation of Legitimate Tools
Search results for “download Zoom”, “get FileZilla” or “Slack installer” often show fake pages with links to malware loaders like IcedID, BATLOADER, or RedLine Stealer.
Keyword Stuffing & Backlink Abuse
Threat actors game Google’s algorithm by stuffing pages with popular keywords and building fake backlinks — helping malicious sites rank higher than real ones.
Why Is This So Effective?
✅ Users trust search engines
Many users believe the top result is the safest.
✅ Attackers move fast
They spin up and tear down malicious domains quickly, staying ahead of blacklists.
✅ No email needed
This bypasses traditional phishing filters.
✅ It’s hard to detect
The user may not even report it — they just think the app “didn’t work”.
These techniques work particularly well on non-technical staff who are searching for tools, fixes, or downloads on their own.
How SEO Poisoning Fits Into Bigger Campaigns
SEO poisoning is rarely the whole story. It’s typically the first step in a wider campaign involving:
Initial access via a fake download
Loader malware that installs remote access or infostealers
Post-exploitation tools like Cobalt Strike
Ransomware or data exfiltration as the final stage
Some of the same campaigns also distribute fake updates and malvertising to maximise reach.
How to Defend Against SEO Poisoning
Limit User Permissions for Downloads
Restrict who can install software and where they get it from. Use a software whitelist or internal catalogue.
Block Access to Malicious Domains
Use DNS filtering and web proxy tools to stop users visiting known bad sites — including fake documentation hubs.
Encourage Safe Search Practices
Train staff to be sceptical of ads and to get software only from verified sources — not through search engines.
Use Ad-Blockers and Script Controls
Prevent click-throughs on malicious ads and block redirections from poisoned sites.
Monitor for Malware Loaders and Beaconing
Look out for signs of tools like IcedID, Cobalt Strike or remote access trojans following a user’s download.
Run Cyber Hygiene Campaigns
Ensure employees know: “If you're looking for software, don’t Google it. Ask IT.”
What to Do If a User Has Visited a Suspicious Page?
✅ Check browsing history
Was a fake site accessed or a file downloaded?
✅ Isolate the machine
If malware is suspected, disconnect from the network.
✅ Scan for payloads
Look for loaders, infostealers, or unusual scheduled tasks.
✅ Assess lateral movement
Some tools activate beacons for remote control.
✅ Call in support

We support organisations in reducing human risk and improving endpoint defences.
Final Thoughts
Search engines are convenient — but they’re also being exploited by attackers. A simple Google search for “VPN download” or “support tool” could lead to a malware infection within seconds.
By limiting who can install software, blocking access to fake sites, and helping staff search safely, you can shut down one of the most overlooked malware delivery vectors.
