I got this email in my work inbox earlier today. Immediately, I was suspicious. Upon further inspection. We can see this is a bad email. The email sender + contents do not match. The linked file should be PDF but it's a JAR file (Java). The link is also suspicious (see URL). Avoid clicking links from email.
