Analysis of Cases of Spoofed Virgin Media Accounts,
Chronic Spam Sent to Addresses Stolen from Email Accounts

Last updated:  20 August 2016


Size of the Problem at Virgin Media


Number of self-reported cases:  About 391
Number of self-reported cases for which email addresses specified: 167

Number of known Virgin Media email addresses with this problem not self-reported:  157

Number of known Virgin Media email addresses with this problem: 334

Total number of identified Virgin Media cases:  About 540

Estimated number of Virgin Media cases: 6,500


Type of Email Address

Virgin Media provides email service under four different domains.   Each has some cases of this spoofing.  Tables 1 and 2 below show the distribution of cases by email domain as a percentage and number.  Without knowing the number of email addresses in each domain, it is not possible to know the significance of this distribution.  Does anyone have information about the relative number of addresses on each domain?

Table 1.  Percentage of Cases by Email Domain.

31% : @blueyonder.co.uk
48% : @ntlworld.com
15% : @virginmedia.net
  6% : @virgin.com

Table 2.  Number of Cases By Email Domain.

105 : @blueyonder.co.uk
162 : @ntlworld.com
  52 : @virginmedia.net
  21 : @virgin.com

Age of Email Accounts

One of the consistent findings for these spoofing cases at Virgin Media is that the email accounts are not new.  Many of those affected by this spoofing problem have owned their email account for more than 15 years.  Table 3 below shows the age of affected Virgin Media email accounts.

Table 3.  Age of Email Accounts

  1:  Four-and-a-half years old
  4:  Five years old
  1:  Six years old
  7:  Seven years old
  4:  Eight years old
  5:  Nine years old

12:  More than ten years old
 1:   Eleven years old
11:  Twelve years old

 2:   Twenty-one years old
 0:   Twenty-two years old
 1:   Twenty-three years old
 1:   Twenty-four years old
 1:   More than twenty-five years old.

Actions Taken to Report Problem

The chronic nature of this problem and the damage done to the victim's personal and professional relationships as the spoofing continues at irregular intervals means that many of those affected seek information from their email provider about the cause and solution.  Tables 4 and 5 below list the actions taken by a subset of affected Virgin Media account holders.

Table 4.  Actions Taken by 68 Virgin Media account holders as a percentage.

72% :   Called Virgin Media one or more times to report problem
35% :   Filled in the Virgin Media Net Report form
26% :   Wrote in to the Virgin Media Community forum 
  7% :   Made contact with the Chief Executive's Office at Virgin Media.

24:  Filled in the Virgin Media Net Report form
18:  Wrote in to the Virgin Media Community forum 
 5:   Made contact with the Chief Executive's Office at Virgin Media.

How Long since Password Change

Many email account holders with this problem had not changed their email account password for "years" before the spoofing began as shown in Table 6 below.  Virgin Media has no password-expiration policy.

Table 6.  Length of Time Since Email Password Changed Before Spoofing Began.

    2: Weeks
  34: Months
104: Years.

Email Addresses Found in Large Hacks

It is unfortunately a common behaviour to reuse an email password on other websites.  During the past few years, there have been a number of large data breaches in which email addresses and web-site passwords were stolen.  The web page "have i been pwned" allows one to check an email addresses to see what information has been stolen.  Checking the affected Virgin Media email addresses gives the results in Tables 8 and 9 below.

Table 8.   Percentage of 172 Virgin Media Addresses Found in Hacks

41% :  Not known to have been stolen
24% :  Adobe
30% :  Linked-In 
  5% :  MoneyBooker
18% :  MySpace
  2% :  Neopets
  3% :  Tumblr
Table 9.  Number of 172 Virgin Media Addresses Found in Hacks

70 : Not known to have been stolen
41 : Adobe
51 : Linked-In 
 8 :  MoneyBooker
32 : MySpace
 3 :  Neopets
 6 :  Tumblr.

Month when Spoofing Began

While the first reports of this epidemic of spoofed emails being sent to addresses stolen from Virgin Media accounts appear to date from August 2015 and correspond to the time when Virgin Media was in the process of moving email accounts from Google hosting to a Dovecot-based system with an Open-Xchange OX App Suite front-end, there have been new cases each month, long after the mailbox moves completed as shown in Table 10 below.

Table 10.  Number of Self-Reported Cases By Month of Onset of Spoofing

 1: August 2015
55: September 2015
31: October 2015
 3: November 2015
 9: December 2015
 2: January 2016
 6: February 2016
 3: March 2016
 5: April 2016
 9: May 2016
 4: June 2016
 3: July 2016
 1: August 2016.

Web Mail Use

As Tables 11 and 12 below show, a large portion of Virgin Media users with this spoofing problem do not use web mail.  As a result, we can rule out a web-mail vulnerability as the method by which accounts have been accessed.  The distribution of browser use is in line with current expected popularity of browsers, with Chrome and Firefox being more popular than Internet Explorer and Safari.

Table 11.  Use of web mail and browsers as a percentage of 174 responses.

36%:   Not using web mail
30%:   Use web mail with Chrome
21%:   Use web mail with Firefox
10%:   Use web mail with Internet Explorer or Microsoft Edge
  6%:   Use web mail with Safari
0.6%:  Use web mail with Pale Moon.

Table 12.  Use of web mail and browser by numbers.

62:  Not using web mail
52:  Use web mail with Chrome
37:  Use web mail with Firefox
17:  Use web mail with Internet Explorer or Microsoft Edge
10:  Use web mail with Safari
  1:  Use web mail with Pale Moon.

Legitimate Emails Not Delivered to Virgin Media Accounts

Last updated 19 August 2016

For many months, businesses, organizations, schools, charities, clubs, government organizations and individuals have been reporting problems delivering legitimate email messages to Virgin Media accounts.  Typically the same messages are being delivered without issue to other domains not managed by Virgin Media.  This partial list of reports is unlikely to be complete.

There have been at least three online articles about this problem, two from The Register on October 5th and 16th, and one from the Northamptonshire Telegraph describing the inability of the local NHS to deliver messages to Virgin Media accounts.
