Facebook's latest site redesign even less secure than before
December 7, 2010
Internet security observers all over the globe have warned that Facebook's latest site redesign will create even more security holes and expose more user information than the old site did.
Internet security firm Sophos cautions that, launched in beta earlier this week and due to be rolled out gradually over the coming weeks, the revamped website is designed in such a way as to encourage users to expose even more information about their daily lives to the dominant social networking site.
Security-wise, the site revamp is seen by most in the Internet community as a big step backwards. For example, the About Profile page encourages users to share experiences, discover common interests, and to highlight meaningful relationships.
That page will have the same effect of highlighting the closest relationships and keenest interest a user might have. Previously, this information would have probably been on a list, but not highlighted as especially important. Now it is, and it's a major concern, among others.
Sophos urges all Facebook users to reconsider just how much data about themselves they really wish to share using the new site, warning that it may not just be their closest friends and contacts who get access to the sensitive information but just about anybody.
“Adding new features to facilitate sharing updates, interests and photos may be appealing to some Facebook users, but people need to be concerned about how much personal data they’re willing to offer online,” said Carole Theriault, senior security consultant at Sophos.
More recently, a decision by the NHS to integrate its NHS Choices health information site into the Facebook Connect platform provoked a warning from online privacy firm Garlik that this would allow the tracking of users on the site.
“Many Facebook users are online friends with complete strangers and so we’d advise Facebook users to carefully reconsider their privacy settings, make sure they’re only sharing information with people that they know and trust and to think carefully about how much personal data they want to make public.”
Although it has never admitted as much, more detailed user information in profiles make Facebook a more attractive platform for advertisers, hence Facebook's direction of travel is always towards encouraging users to share more with a wider pool of people.
But make no mistake, Facebook isn't the only social site with security issues. Twitter and others also have their share of security flaws as well.
In September, Twitter said it identified and fixed some cross site scripting holes that led to a meltdown on August 10, only to undo this fix with a later web site update. Again.
It's becoming clearer now that on average, social sites aren't secure, and these latest security flaws being discovered are troubling. And if it isn't security bugs, it's privacy issues that users seem to be facing more and more these days.
So now some users are asking: is all of this really worth it? Am I wasting my time and energy on something that isn't worth considering, given all the security issues.
But wait-- it even gets worse.
The security flaw was mostly used for mischief but there were incidents of porn and shock site redirects as well, Internet security researchers say. A worm, without a malicious payload, took advantage of the vulnerability to cause users to retweet their original Tweets after they rolled their mouse over a link, and then creating hundreds of thousands of spam message in the process, on top of creating other issues.
Only surfers using Twitter.com were exposed to the vulnerability. Third party clients were unaffected, at least for now. We will keep you updated however, if the situation should change.
A Japanese Web application developer called Masato Kinugawa is credited with discovering the security hole in August and used it to post multi-coloured rainbow tweets. Then, Scandinavian app developer Magnus Holm developed at least one of the "worms" that took advantage of the security vulnerability.
Holm created the worm to test what was possible, but not expecting much that his creation would spread so quickly either. In fact he was astonished at the speed the exploit was travelling at.
For its part, Twitter said that while the attack created a huge amount of spam and confusion, no greater security threat was posed and users of compromised accounts need not change their passwords.
However, both Kinugawa and Holm all disagree on Twitter's comments, and some say Twitter isn't proactive enough in the matter.
Up to 500,000 users (about 100 per second) may have fallen victim to the cross site scripting attack, according to an analysis by Kaspersky Labs. And other similar security firms agree.
"Overall, there is no need to change passwords because user account information wasn't compromised through this exploit," Twitter has reassured users in a blog post written after the security breach.
