Scam Group Partnerstroka Uses Browser Locker Against Latest Google Chrome Build

[silversurfer]

Malwarebytes Labs Jérôme Segura details in a new report the behavior of a new malvertising campaign named Partnerstroka which uses a browser locker technique specifically designed for Google Chrome as well as adaptive algorithms to cover most browsers and platforms.

Tech support scams are still a prime threat for most Internet users and can use multiple ways of luring their victims, from telephone calls impersonating Microsoft staff to malicious tech support ads and pop-ups designed to redirect targets to payment pages.

Among all types of threat actors observed using malvertising methods to scam their victims, Partnerstroka is a new tech support scam group which uses old and verified techniques but with a twist: they use a new type of browser locking method specifically designed for Google Chrome.

More precisely, as Malwarebytes Labs found out during their research, this new browlocker affects the latest Google Chrome 69.0.3497.81 version, and it works by hijacking the user's mouse by replacing it with an offset mouse pointer and preventing him from closing the page.
