Nasty new IE vulnerability
Most people reading are probably aware of the common trick whereby spammers and other assorted ne’er-do-wells publish URLs with usernames that look like hostnames to fool people in to trusting a malicious site—for example, http://www.microsoft.com&session%123123123@simon.incutio.com. This trick is frequently used by spammers to steal people’s PayPal accounts, by tricking them in to “resetting” their password at a site owned by the spammer but disguised as PayPal.com.

High security is low security
Via Crypto-Gram, a great piece from Bruce Tognazzini about how tough security measures can actively reduce the security of a system:
[... 225 words]Signing comments on blogs
Adrian Holovaty has implemented reserved comment names in his blog, a feature that prevents anyone apart from him from using the names “Adrian”, “Adrian H.” or “Adrian Holovaty” when posting a comment. François Nonnenmacher suggests extending the idea to allow people to “confirm” their authorship of comments on any blog using a TrackBack sent to their site that in turn causes them to be sent an alert email, which they can then use to confirm their comment. I like his idea of authentication based on URLs (email addresses are no good; they should not be publically displayed for fear of spam harvesters) but I think I’ve come up with an alternative authentication scheme that removes the need for the user to manually confirm authorship. This is pretty complicated, so bare with me.

Via Scott, a clever PHP technique for ensuring data sent to the browser as a cookie or hidden form variable isn’t tampered with by the user:

Remembering passwords
Via Scott, an article with some great tips on remembering your passwords. It includes the following vitally important tip:
[... 273 words]XML security on SitePoint
Getting Started with XML Security is a SitePoint article of epic proportions. I had never really looked at any of the XML security applications but this article appears to cover the lot.
[... 33 words]OWASP Security guide
The Open Web Application Security Project (OWASP) have a free guide to building secure web applications, which covers a large range of common problems such as cross site scripting and SQL injection vulnerabilities. The report is a 60 page PDF and although I haven’t had time to go through it yet it looks like an excellent read.
[... 74 words]Palladium
Via Boing Boing: Seth Schoen’s notes on Palladium after a meeting with Microsoft. Cory Doctorow points out that Seth is probably the most knowledgeable tech person to have been briefed on Palladium by MSFT without signing an NDA
and his post certainly makes interesting reading. Palladium has had a lot of coverage since the Newsweek article announcing it first broke, with Robert Cringely providing some of the best analysis (in my opinion at least). The Register also has a story about Palladium which introduces some more information and guestimates on a shipping schedule.
