Warning regarding fraudulent voicemail emails
Hello all,
We’ve received reports of fraudulent emails about pending voicemail. These are a very common tactic of criminals to trick people into giving out their usernames and passwords – and are something I wanted to write to you all about.
First off – if you haven’t signed up to receive voicemails in your email then all such messages are fraudulent. If you have – I want to share some screenshots of legitimate and fraudulent messages so you can see the differences:
The first is an example of a voicemail left by a number from off-campus. They will often contain a location that the call originated (or appeared to originate) from and the phone number. I’ve blacked out the full number – but you can see the example here. A few things to note:
- There are no links or even message text – just an attachment with a ‘WAV’ file
- There is no indication that this is an external message
- The from address shows as “Cisco Unity Connection Messaging System <unityconnection@cuc-pub>” – which is the internal voicemail system.
The second below is from an on-campus number and it shows the name and their extension but is otherwise mostly the same as the off-campus one. It does have the ‘from’ address – not as an @newpaltz.edu address – but this @cuc-pub domain though (you can disregard the address other than noting it isn’t a real domain).
Below is an example of a fraudulent voicemail. Each such fraudulent message may look completely different – but they all have:
- An external message warning
- An external email address
- Links – sometimes several (if you hover over the links – you can see that they are not New Paltz addresses). In this case – it was sent by an almost certainly compromised email address in the United Kingdom – and was going to a SharePoint site (though not New Paltz – one with an address to downehouseschool – a UK boarding school).
Any one of these red flags should be enough to be suspicious – but if you need more – if you were to click on one of these fraudulent links they will bring you to a login page (our voicemail system just sends the voicemail as an audio attachment – no links).
As always – thanks to those who are both reading these messages – and reporting fraudulent/suspicious emails.
