Security Warning – Malicious OneClass Chrome Extension

security-warning-iconA malicious OneClass Chrome Extension is part of a current phishing scam which, if installed, may send email on users’ behalf and also attempts to collect user credentials. The OneClass Chrome Extension is not available directly via search in the Chrome Extensions Store and users, both instructors and students, are being phished with a link.

During installation, the extension requests permissions to “Read and change all your data on the websites you visit”.  The installation process counts on users’ tendency to accept terms without reading.

The extension adds a button inside the Blackboard Learn pages to “Invite Your Classmates to OneClass”.

The plugin will email all email users within a class (utilizing Blackboard URLs and resources, which are functioning as designed) to promote the OneClass plugin/product.  The plugin also has code that attempts to collect and send the user’s credentials (both username and password).

The mail content is:

“Hey guys, I just found some really helpful notes for the upcoming exams for <University Name> courses at <oneclass signup URL>.  I highly recommend signing up for an account now that way your first download is free!”

Please DO NOT install this extension, and if you receive an email anything like the one above please DO NOT click anything in the email.  Just delete the email. If you have installed this extension, please uninstall it immediately and change your Valencia password.
