As DocuSign proudly boast of ‘more than 1,000,000 paying customers and over a billion users worldwide’, it’s easy to see why the company is such an appealing target for impersonation in phishing scams.
The MailGuard team are currently blocking credible scam emails impersonating DocuSign, with a subject line reading ‘Sign and Seal: Completed [document name] Await Your Approval’, the emails feature DocuSign branding and relatively few grammatical errors, that are often a tell-tale sign for spotting a scam. Instead, the emails simply offer ‘Review Document’ links, which are obfuscated via a redirect from a different website.
An example of the email is shown below:
After clicking on the ‘REVIEW DOCUMENT’ link, users are presented with a Captcha challenge to verify that they are a human, before being taken to a login page that imitates a typical Microsoft ‘Sign in’ window.
However, it is in fact a phishing page that has been purpose built for the scam. The replica Microsoft ‘Sign in’ page pre-populates the target victims’ email credentials and features their employers’ company logo and an image relating to the company, likely corresponding to the domain portion of the email address. In the example below, the page features a photo from Google Maps of a regional office belonging to the targeted company.
The phishing pages are presumed to belong to a compromised domain, and they’re hosted behind Cloudflare. After adding your password, the page provides an error prompting users to re-enter their details. A tactic designed to assist the cybercriminals in harvesting variants of the users sign in credentials for user in later attacks.
By entering your password, you are inadvertently disclosing your Microsoft access credentials to the cybercriminals behind the attack.
Scams impersonating DocuSign that lead to a Microsoft login page are not uncommon, such as these ones from February and May last year.
MailGuard advises all recipients of this email to delete it immediately without clicking on any links. Providing your personal details can result in your sensitive information being used for criminal activity and may have a severe negative impact on your business and its financial well-being.
MailGuard urges users not to click links or open attachments within emails that:
- Are not addressed to you by name.
- Appear to be from a legitimate company but use poor English or omits personal details that a legitimate sender would include.
- Are from businesses that you were not expecting to hear from, and/or
- Take you to a landing page or website that is not the legitimate URL of the company the email is purporting to be sent from.
Many businesses turn to MailGuard after an incident or a near miss, often as a result of an email similar to the one shown above. If unwanted emails are a problem for your business, don’t wait until it’s too late.
