XSS Flaw in TweetDeck
Another example of how secure coding can help all. The use of "white lists" in code can eliminate this exploit from occurring. White lists are used to only allow certain characters to be inputed into form fields and not allow characters that are normally part of XSS attacks. OWASP has information to help with this.

Re: XSS Flaw in TweetDeck
Exactly correct Randy!  This is yet another example where putting secure coding first and foremost would prevent a major issue.

Re: XSS Flaw in TweetDeck
Maybe the major retailers will learn from these incidents but you would think the Target would have been a wakeup call for all.

Surprised
I was pretty surprised Tweetdeck got caught out by this to be honest. It's large enough and has been operating long enough that you'd think it would have some solid people in place to ward off problems like this.

That said, I did hear that it was to do with the heart symbol which hasn't been around long, so it was a relatively recent exploit it seems.

Browser Alternatives - Safe?
Some mention has been made of trying alternatives to the usual suspects of the web browser world (hardened Lynx (text only), WhiteHat Aviator), but let's not forget that not all web traffice goes across a browser - many applications act like web browsers on the inside and are just as exploitable through methods like XSS.  This is especially true with desktops like GNOME where just about every app I use tugs on Mozilla APIs or similar.  As long as the key web elements are there XSS can still work on the client-side as if you were using a browser.  I
mention this only because users shouldn't think because they turn to other apps to access TweetDeck they are safe.

How Machine Learning, AI & Deep Learning Improve Cybersecurity
Machine intelligence is influencing all aspects of cybersecurity. Organizations are implementing AI-based security to analyze event data using ML models that identify attack patterns and increase automation. Before security teams can take advantage of AI and ML tools, they need to know what is possible.
