This email, which purports to be from electronic signature service DocuSign, claims that your agreement with Australian telecommunications company Optus has been completed. It urges you to open an attached file to view the signed agreement.
The email features the Optus logo and includes an attached .zip file named ‘Optus agreement no PDJT-989812.zip’.
However, the email is not from DocuSign and has no connection to Optus.
And the attachment does not contain any sort of ‘agreement’ document, signed or otherwise. Instead, the email contains a dangerous executable file that, if opened, can install malware on your computer.
Once installed, the malware may download even more malware that can steal passwords and other personal information from the infected computer. The malware may also allow criminals to take control of the computer. In some cases, the initial malware component may download ransomware that can lock your files and then demand a fee to retrieve them.
The criminals know that at least a few less experienced computer uses may be panicked into opening the attached file in the mistaken belief that their identity or information has been used without their knowledge to sign up for an Optus agreement. Recipients who have recently conducted business with Optus may also be especially vulnerable to this attack.
If you receive this email, do not open any attachments or click any links that it contains.
