The MSP Security Gap
The download that was not the download
The scenario:
Your client's employee needs a common tool. A PDF editor, a meeting app, a file converter. They search for it and click the top result.
The site looks right. They download the installer and run it.
How it unfolds:
The top result was an ad or a planted page, not the real vendor. The installer works, the app opens, everything looks normal.
In the background it dropped a loader that gives the attacker a way in. Because the employee went looking for the software and installed it themselves, nothing looked like an attack. No phishing email. No bad attachment.
They invited it in through a search result. Days later the attacker uses the foothold to move across the network.
The warning signs:
A sponsored or ad result sitting above the real vendor site.
A download domain that is not the vendor's own.
An installer asking for more access than the tool needs.
New software on a machine nobody logged as approved.
Stop it:
Get software from the vendor's own site, not a search ad.
Keep a short approved-source list for the common tools your clients use.
Restrict software installation to admins, so one click cannot reach the whole machine.

PS: Your client went looking for this one and installed it themselves. No email to flag, no attachment to scan. The install is the first point where it becomes visible.
