Tackle bar reveals hp.com. Browser shows scammers’ malicious textual content anyway.

Not the Apple web page you are searching for

“If I confirmed the [webpage] to my mother and father, I do not suppose they might be capable of inform that that is pretend,” Jérôme Segura, lead malware intelligence analyst at Malwarebytes, mentioned in an interview. “Because the person, for those who click on on these hyperlinks, you suppose, ‘Oh I am really on the Apple web site and Apple is recommending that I name this quantity.’”

The unknown actors behind the rip-off start by shopping for Google advertisements that seem on the prime of search outcomes for Microsoft, Apple, HP, PayPal, Netflix, and different websites. Whereas Google shows solely the scheme and host identify of the location the ad hyperlinks to (as an illustration, https://www.microsoft.com), the ad appends parameters to the trail to the suitable of that handle.

In order that they’re simply spitting out no matter question you have got.”

To date, Segura mentioned, he has seen the scammers abuse solely Google advertisements. It is not recognized if advertisements on different websites could be abused in an identical manner.
