Estate agent Foxtons is currently investigating a possible data breach , which may have resulted in the personal information of 10,000 customers being compromised . A list including the email addresses , usernames and passwords , many partially obscured , of alleged MyFoxtons users was posted on Pastebin and linked to on several security sites , but has now been removed . The list is still available elsewhere , reports PCPro.co.uk and Softpedia . " We have been able to download the list of usernames and passwords that were posted and are currently running checks to determine its veracity , " Foxtons said in an email to MyFoxtons users . Although the list does n't contain financial information like credit card details , access to a user 's MyFoxtons account could allow a person access to their home address and phone number . Additionally , a hacker could gain access to MyFoxtons ' features that allow landlords to electronically sign documents , manage the payments of rents online and see the deposit registration numbers of their tenants , according to this online demo . It is not currently known who is behind the reported breach , or how they may have gained access to the data . The list is reportedly labelled " Part 1 " , potentially suggesting that more data is to come . Foxtons declined to comment . ;
