Fwd: Security (or lack of) at Number26 2017-01-09 No Comments

Hi! I would like to share a talk that I attended at 33c3. It’s about a company with a banking license and accounts with actual money. Some people downplay these issues as “yeah, but the issues were fixed” and “every major bank probably has something like this”. I would like to reply: With a bit […]

arc4random_uniform and avoiding modulo bias when using a random number generator 2016-07-30 No Comments

Using the arc4random_uniform function is recommend over using arc4random: Former is advertised as not having “modulo bias” issues, see man arc4random. (So I got curious, searched the web a bit, found this blog post, this answer and this link to the source code of one version used by Apple’s. It took me a bit to […]

Disable Komodo IDE debugger (bound to, run by default) 2016-03-14 No Comments

Komodo IDE starts a debugger bound to, by default. Maker ActiveState’s reaction was rather unprofessional at the time when I asked for an option to bind to, instead. I can no longer add links to that post, but I can link to my demo Komodo IDE exploit script up here. Now it seems […]

Comment vulnerability in WordPress 4.2 2015-04-27 No Comments

Hanno Böck tweeted about WordPress 4.2 Stored XSS rather recently. The short version is: if an attacker can comment on your blog, your blog is owned. Since the latest release is affected and is the version I am using, I have been looking for a way to disable comments globally, at least until a fix […]

Apache AddHandler/AddType vulnerability: Magento <1.9.1 affected 2015-04-26 No Comments

I ran into an example of a web application vulnerable to Apache AddHandler/AddType misconfiguration by chance today. The releases notes of Magento Community Edition 1.9.1 point to a remote code execution vulnerability. Interestingly, the section Determining Your Vulnerability to the File System Attack is precisely a switch from AddHandler to SetHandler. Fantastic! Let’s see if […]

“Your browser fingerprint appears to be unique among the 5,198,585 tested so far”. What?! 2015-04-11 7 Comments

While https://panopticlick.eff.org/ is not really new, I learned about that site only recently. And while I knew that browser self-identification would reduce my anonymity on the Internet, I didn’t expect this result: Your browser fingerprint appears to be unique among the 5,198,585 tested so far. Wow. Why? Let’s try one of the others browsers I […]
