Most people know at this point that when searching for a popular software package to download, you should be very careful to avoid clicking on any of the search ads that appear, as this has become an extremely common vector for distributing malware to unsuspecting users.

If you thought that you could identify these malicious ads by checking the URL below the ad to see if it directs to the legitimate site, think again! Malware advertisers have found a way to use Google's Ad platform to fake the URL shown with the ad to make it appear like a legitimate ad for the product when in fact, clicking the ad will redirect to an attacker controlled site serving malware.

Don't click on search ads or, even better, use an ad-blocker so that you never see them in the first place!

Presumably you can hover over the link to see the actual URL (which I think is best practice anyway), or is it more sophisticated than that?

AFAIK even legitimate ad clicks will first direct to an analytics platform before redirecting to the destination site, so that they can track click through rates and where the referral came from. So it is unlikely that ad links will actually go to the website you expect them to even in normal scenarios. It is actually this mechanism that the malicious ads described in the article are using to fake the display URL.

I would always out of habit avoid any links that go to somewhere other than the advertised destination - so if it goes to an analytics platform I would copy and paste the text if the text of the link is a URL, or find an alternative. Always hovering links and being absolutely sure of where they go should really be taught as standard practice.

I always check the status bar but I actually noticed the other day on LinkedIn or maybe Facebook, that the status bar said one thing, but the link was different,

E.g the hover over said https://website.com but the actual link was something like https://linkedin.com/linkout/wbdjdhgaj?user=xhedb

That type of thing is concerning. What browser are you using out of interest?

[–] [email protected] 1 points 9 months ago (1 children)

That's trivial to do where you control the link text. For example: https://www.google.com/
