Potential victims receive an attachment disguised as an Excel document that is actually an HTML document with a URL-encoded piece of text. A report prepared by Trustwave researchers notes that decoding this text makes it possible to find more coded content.
Specialists mention that the strangest thing about this campaign is that malicious code is downloaded in hidden fragments from a remote location and then assembled to a local location: “This allows threat actors to bypass protection mechanisms like Secure Email Gateways.”
Finally, Trustwave mentions that the URL that receives the stolen credentials in this campaign remains active, so office 365 account administrators need to stay on top of these security risks, ignoring any email sent by unknown users and trying not to visit potentially malicious websites.
