Microsoft’s IE Latest Flaw: ‘Cookiejacking’
Comments Off on Microsoft’s IE Latest Flaw: ‘Cookiejacking’
A technology security researcher has discovered a flaw in Microsoft Corp’s widely used Internet Explorer browser that he said may allow hackers to steal credentials to access FaceBook, Twitter and other websites.
He coined the technique as ”cookiejacking.”
“Any website. Any cookie. Limit is just your imagination,” said Rosario Valotta, an independent Internet security researcher based in Italy.
Hackers can exploit the flaw to access a data file stored inside the browser known as a “cookie,” which holds the login name and password to a web account, Valotta wrote.
Once a hacker has that cookie, he or she can use it to access the same site, said Valotta, who calls the technique “cookiejacking.”
The vulnerability affects all versions of Internet Explorer, including IE 9, on every version of the Windows operating system.
To take advantage of this flaw, the hacker must first persuade the victim to drag and drop an object across the PC’s screen before the cookie can be hijacked.
That sounds like a difficult task, but Valotta said he was able to do it fairly easily. He built a puzzle that he put up on Facebook in which users are challenged to “undress” a photo of an attractive woman.
“I published this game online on FaceBook and in less than three days, more than 80 cookies were sent to my server,” he said. “And I’ve only got 150 friends.”
Microsoft said there is little risk a hacker could succeed in a real-world cookiejacking scam.
“Given the level of required user interaction, this issue is not one we consider high risk,” said Microsoft spokesman Jerry Bryant.

Google confirmed that it’s starting to roll out a server-side patch for a security vulnerability in most Android phones that could allow hackers to access important credentials at public Wi-Fi hotspots.
“Today we’re starting to roll out a fix which addresses a potential security flaw that could, under certain circumstances, allow a third party access to data available in Calendar and Contacts,” said a Google spokesman in an emailed statement. “This fix requires no action from users and will roll out globally over the next few days.”
Google will apparently apply the fix to its servers since it does not need to push out an over-the-air update to Android phones.
Experts applauded Google’s fast reaction.
“It’s impressive how quickly Google fixed this,” said Kevin Mahaffey, chief technology officer and a co-founder of San Francisco-based mobile security firm Lookout. “Google’s security team, especially on Android, is very, very quick to deal with issues.”
Whatever Google is implementing will shut the security hole that three German researchers publicized last week.
According to the University of Ulm researchers, who tested another researcher’s contention last February that Android phones sent authentication data in the clear, hackers could easily spoof a Wi-Fi hotspot — in a public setting such as an airport or coffee shop — then snatch information that users’ phones transmitted during synchronization.
In Android 2.3.3 and earlier, the phone’s Calendar and Contacts apps transmit information via unencrypted HTTP, then retrieve an authentication token from Google. Hackers could eavesdrop on the HTTP traffic at a public hotspot, lift authentication tokens and use them for up to two weeks to access users’ Web-based calendars, their contacts and also the Picasa photo storage and sharing service.
