The Anatomy Of The Twitter Attack. Long-winded explanation of the recent Twitter break-in, but you can scroll to the bottom for a numbered list summary. The attacker first broke in to a Twitter employee’s personal Gmail account by “recovering” it against an expired Hotmail account (which the attacker could hence register themselves). They gained access to more passwords by searching for e-mails from badly implemented sites that send you your password in the clear. # 20th July 2009, 12:55 am

17-year-old claims responsibility for Twitter worm. It was a text book XSS attack—the URL on the user profile wasn’t properly escaped, allowing an attacker to insert a script element linking out to externally hosted JavaScript which then used Ajax to steal any logged-in user’s anti-CSRF token and use it to self-replicate in to their profile. # 12th April 2009, 7:22 pm

Twitter Don’t Click Exploit. Someone ran a successful ClickJacking exploit against Twitter users, using a transparent iframe holding the Twitter homepage with a status message fed in by a query string parameter. Thiss will definitely help raise awareness of ClickJacking! Twitter has now added framebusting JavaScript to prevent the exploit. # 12th February 2009, 7:56 pm

Weak Password Brings “Happiness” to Twitter Hacker. The full story on the Twitter admin account hack. I bet there are a LOT of web applications out there that don’t track and rate-limit failed password attempts. # 7th January 2009, 12:04 pm

The Twitter administrator hack was a dictionary attack. I quoted Blaine earlier suggesting that the recent Twitter mass-hack was due to a Twitter admin password being scooped up by a rogue third party application—this was not the case, as Alex Payne explains in a comment. # 6th January 2009, 11:56 pm

Antipatterns for sale. Twply collected over 800 Twitter usernames and passwords (OAuth can’t arrive soon enough) and was promptly auctioned off on SitePoint to the highest bidder. # 2nd January 2009, 10:48 am

Now You Can Sign Into Friend Connect Sites With Your Twitter ID. Great. Now even Google is asking me for my Twitter password. Slow clap. How’s that Twitter OAuth beta coming along? # 15th December 2008, 5:20 pm

WebRunner 0.7—New and Improved. A simple application for running a site-specific browser for a service (e.g. Twitter, Gmail etc). This is a great idea: it isolates your other browser windows from crashes and also isolates your cookies, helping guard against CSRF attacks. # 27th September 2007, 1:55 pm

The Twitter API Respects Your Privacy. Not Twitter’s fault: The users who exposed their data through Twittervision had given that site their username and password; Twittervision was failing to hide protected updates. # 24th May 2007, 11:37 pm

There’s a hole in your Twitter. If you’ve been using friends-only messages on Twitter they may currently be exposed via the API. # 24th May 2007, 5:03 pm
