Today I have received an email with an attachment.
The contained message reads: "Sir/Madam, we have logged your IP-address on more than 40 illegal Websites. Important: Please answer our questions! The list of questions are attached."
The attachment is called document.zip. In order to trick users into believing they are dealing with a document, the executable found inside the .zip archive bears a PDF icon.
A new malware distribution campaign is producing rogue emails purporting to come from the FBI and attempting to scare users into opening malicious attachments.
Cyber criminals behind this attack are hoping to scare people into believing they are being investigated by federal authorities because they accessed illegal online content.
What I would recommend is make sure your antivirus software is up to date. Better “DO NOT OPEN” such emails.
