EFF Tool Offers New Protection Against 'Firesheep'

Filed under

The Electronic Frontier Foundation (EFF) has launched a new version of HTTPS Everywhere, a security tool that offers enhanced protection for Firefox browser users against "Firesheep" and other exploits of webpage security flaws.

HTTPS secures web browsing by encrypting both requests from your browser to websites and the resulting pages that are displayed. Without HTTPS, your online reading habits and activities are vulnerable to eavesdropping, and your accounts are vulnerable to hijacking.

Unfortunately, while many sites on the web offer some limited support for HTTPS, it is often difficult to use. Websites may default to using the unencrypted, and therefore vulnerable, HTTP protocol or may fill HTTPS pages with insecure HTTP references. EFF's HTTPS Everywhere tool uses carefully crafted rules to switch sites from HTTP to HTTPS.

This new version of HTTPS Everywhere responds to growing concerns about website vulnerability in the wake of Firesheep, an attack tool that could enable an eavesdropper on a network to take over another user's web accounts -- on social networking sites or webmail systems, for example -- if the browser's connection to the web application either does not use cryptography or does not use it thoroughly enough.

  • GCC for New Contributors
    I’m a relative newcomer to GCC, so I thought it was worth documenting some of the hurdles I ran into when I started working on GCC, to try to make it easier for others to start hacking on GCC. Hence this guide.
  • #1: Easy Package Registration
    Last month, Brian Ripley announced on r-devel that registration of routines would now be tested for by R CMD check in r-devel (which by next month will become R 3.4.0). A NOTE will be issued now, this will presumably turn into a WARNING at some point. Writing R Extensions has an updated introduction) of the topic.
  • Emacs as C IDE and JHBuild
    Although Builder clearly is The Future as GNOME IDE, I still all my coding in Emacs, mostly because I have been using it for such a long time that my brain is to all the shortcuts and workflows. But Emacs can be a good IDE too. The most obvious everyday features that I want from an IDE are good source code navigation and active assistance while editing. In the first category are tasks like jumping to symbol's definition, find all callers of a function and such things. For editing, auto-completion, immediate warnings and error reporting, semantic-aware re-factoring are a must. Specifically for GNOME related development, I need all this to also work with JHBuild.
