Users of the service, hoping to evade state censorship/snooping, encrypt the traffic that then gets routed anonymously around the globe. But
After the release of FireSheep, Facebook took an important step to help protect Facebook user accounts by allowing users to choose to keep an encrypted connection as long as they used just Facebook and intelligently designed apps. Savvy users immediately discovered that if they tried to use grossly insecure apps such as Farmville, 21 Questions,
Recently Senator Schumer from New York wrote a letter (http://www.infosecurity-us.com/view/16328/senator-schumer-current-internet-security-welcome-mat-for-wouldbe-hackers/) to Twitter, Yahoo, and Amazon asking them to make SSL the default for internet connections. What this means is that instead of an http connection they should provide and https connection by default. This is important because with http connections you are exposed to risk
With the release of Firesheep the Firefox add on HTTPS Everywhere has increased in popularity as it helps ensure that your Facebook session is encrypted.

Further to our blogs on HTTPS and SSL certificate issues – see http://www.eset.com/threat-center/blog/2009/10/06/ssl-to-certify-web-security-is-not-to-guarantee-it and http://www.eset.com/threat-center/blog/2009/10/04/truth-fiction-and-https – Sebastián Bortnik has been talking to us today about a video that ESET Latin-America have put together demonstrating a phishing attack using HTTPS. If your Spanish is better than mine, you can check it out here. However, we’ve been working on an
Hard on the heels of the translated blog by Sebastián Bortnik that I posted at the weekend comes news from the Register (http://www.theregister.co.uk/2009/10/05/fraudulent_paypay_certificate_published/) of a bogus Paypal SSL certificate released yesterday exploiting a bug in Microsoft’s crypto API that has remained unpatched for more than two months, when Moxie Marlinspike (can I have a handle
Update, 19th October. I was recently contacted indirectly by Eddy Nigg of StartCom, who points out, quite rightly, that this issue is not specific to StartCom, nor a problem created by StartCom. He commented further in a comment to Dan Raywood’s article for SC Magazine arising from this blog entry, and I think it’s only
Lots of fuss about the paper presented at the Chaos Communication Congress in Berlin yesterday by Alexander Sotirov et al. The paper describes a proof-of-concept attack using a weakness in the MD5 cryptographic hash function to create a rogue Cerification Authority certificate using a hash collision (essentially, two messages with the same MD5 hash value).
