Malicious emails

Over the past few days I have received several emails to my ntlworld account. All had zip attachments and were obviously malicious. All different senders and account addresses.

"Here is the file you asked for"

"This is the update you require"

"The attached file is for your approval"

Plus the usual "letter from the bank" format.

I thought VM blocked transmission of any file with an attached compressed or EXE file?

Re: Malicious emails

You'll be interested in this:

http://help.virginmedia.com/system/selfservice.controller?CONFIGURATION=1001&PARTITION_ID=1&TIMEZONE...

although I have a horrible feeling that this note applied to the former Google based e-mail system.

I've done a Forum search and I can't find anything about the current system. Let's hope the VM Forum Team know or one of my other SU colleagues.

Re: Malicious emails

That horrible feeling was right. AFAICS, none of the executable extensions are blocked unless they contain a known virus characteristic; that is either incoming or outgoing.

Re: Malicious emails

The trouble with that is if it is an UNKNOWN virus signature.

Re: Malicious emails

For an email provider this should have been a no-brainer decision when securing the service, no executable attachments allowed. Let us hope Virgin Media react appropriately to fix this security issue.

Re: Malicious emails

First of all, someone from VM would have to read this thread...

Re: Malicious emails

The VM Forum Team read all the posts and threads. But the volume of activity is such that this is not a quick process. They are read in strict date order.

I have asked for clarification and the question has been referred for further advice. I am sure it has been answered before but I can't find it in a search.

Re: Malicious emails

I knew the answer was somewhere on the Forum but it is in the Superusers area which is private. This is the list of file types that should be blocked:

Re: Malicious emails

Hi Taf,

We meet again Smiley Happy

Thanks for reporting this, I am already asking questions to find out what may have resulted in you receiving these types of files.
I shall provide an update as soon as I get a reply. 

By the way, were those emails forwarded from another account or sent direct? And which mail folder were they delivered to - Inbox or Spam for instance?

 

@HowardML - thanks for tracking the info about the file types. I've now managed to locate the source on our help pages here.
