Once users click on this post, they are redirected to another page that urges them to install the said theme. Note that this attack only works on either Google Chrome or Mozilla Firefox browsers. Clicking the Install button on the page will prompt the download of the maliciousfile, FacebookChrome.crx which Trend Micro detects as TROJ_FOOKBACE.A. When executed, TROJ_FOOKBACE.A executes a script that is capable of displaying ads from certain websites.

Suchita Vishnoi, Head – Marketing, Trend Micro (India & SAARC) commented that "The fact that the attack itself is focused on Chrome and Firefox may mean that cyber criminals are targeting extension-compatible browsers, as well as going after more popular browser choices. This is not the first attack of its kind, but considering this the extension-capable browsers are coming to the forefront now" she further added "It is advised users to inspect such Links closely and to never click any of the links provided in these. It is typical for spammers to use prominent events/ brands such as Reader's Digest, or enticing contests to cloak their malicious schemes. Users should first verify with trusted sources about the existence of these promos to avoid becoming victims of such ruse. Contacting the organization purportedly behind the message by other means such as actual on-site visitation or a call on their hotline should also work as a way to verify if the message itself is in fact true".
