Attackers have launched a series of phishing attacks impersonating reputable secure share providers, which are used for securely sharing files. The lures contain links or attachments containing the supposed document. Interacting with the link or attachment leads to the installation of credential harvesting malicious software (malware). The sending address for the emails does not match the expected company domain for the secure share provider.

Recent email-based attacks have abused Microsoft’s legitimate OneNote application to share malicious files. The emails use subject lines like “New Document Shared with you” and encourage the recipient to follow a link to view a shared OneNote file.  The OneNote link leads recipients to a shared document which contains the text “DOUBLE CLICK TO DOWNLOAD THE FILE NOW.”Some attacks may also distribute similar malicious OneNote files as email attachments.

Cybercriminals have launched phishing attacks using apparently compromised SAP Concur and DocuSign accounts to distribute malicious emails.  The phishing lures use financial themes, such as an expense report on SAP Concur or a financial settlement document on DocuSign. The lures include malicious links.
