Office365 “Virus” – How Did I Get It

One of the main way via which programs that cause redirects to web pages, like the Office365 scam is believed to be via software bundling operations. These types of activities often involved third-party programs that are often downloaded by users. Such programs include drivers, media players, downloaders, converters and any other free helper program you can think of. They often come embedded with ad-supported programs and PUPs which are cleverly masked as a seemingly legitimate software that is added to the installers of those programs. One such software may be the one which introduces the Office365 phishing screens on the victim PCs. But it is not easy to detect those programs when you install freeware, since they are often concealed well within the “Advanced” or “Custom” installation modes.

Another method and scenario via which the Office365 may be spread on your computer system is if you have tried to download a document by clicking on a web link and have received the following notification:

Such web links may be sent to your via e-mail to pretend to lead you to the online viewing of any form of seemingly important document from the likes of an invoice, receipt or something urgent.

Office365 Phishing “Virus” – Analysis

In addition to modifying Windows, the Office365 redirect PUP may also heavily modify your web browser and change your home page, new tab page and other segments of your browser so that you use suspicious third-party search engines in order to see different advertisemetns.

In addition to this, the Office365 pop-up “virus” may also introduce various types of tracking technologies on your web browser with the purpose to obtain your:

  • Online search history.
  • Online browsing history.
  • Online clicks.
  • Keystrokes you entered on your browser.
  • Ads you have clicked on.

These technologies may be used by the Office365 “Virus” in order to cause different types of advertisements on your computer. The main one of those is the fake Office365 login page, which resembles the one used by ProtonMail. The page appears like the following:

But Office365 is not the only target of the cyber-criminals who are behind this phishing attack. They also add other forms of Sign In, hopefully to steal your credentials of other services you might be tricked into logging in. The main imitation of these phishing messages is the anonymous e-mail service protonmail and the sign-in screen even adds ©2017 PROTONMAIL.COM underneath it in order to increase trust:

If you see the following screen, it is very important not to entery any usernames and passwords in it and immediately check your computer for malware to make sure that it is protected and you do not see any more phishing attempts on your credentials.
