It seems that Microsoft is going to offer subscription and sales of individual office applications in the Windows Store. The office package will still be available as a package but for the first time, we will get single applications as standalone ones available for purchase. This is a very interesting decision by Microsoft and I fully support it, this time users will be able to pay less and to choose only applications that they need instead of paying for the whole package and not using it.

Roblox is a very popular online game with millions of gamers playing it each day and as such it will naturally bring a lot of malware and attack on players trying to steal and exploit them for monetary gains. The latest attack and high-profile stealing of currency and assets happened exactly in Roblox.

Malicious activities have been reported to come from chrome extensions. So far 2 extensions have been identified that have hidden malware inside them but there could be more of them currently undetected. Extensions work as a front while in the back they mine user logins and other data in order to steal stuff from the Roblox platform.

To make things worse some of the malware is within long extensions like SearchBlox. The SearchBlox extension allows you to search quickly for other users if it was legitimate but has been compromised within the last month. There is evidence that people are stealing Roblox currency with the data gathered by the hidden backdoor in it.

SearchBlox extension is still Active in Chrome Web Store, with the primary listing still with the "Featured " badge. Google is actively removing malicious software from its storefront on a regular basis but this one still lingers in it.

If you or your kid have this Chrome extension installed, uninstall it right away and always be careful about which extension you install and give access to your system, keep them updated and check various blogs and article sites to inform yourself when a bad one is found.
