After signing in to Facebook, your friends can see that you’re online by default. You can open the chat window in the lower right corner of the window and choose to go offline, but after your next login to Facebook, this setting is lost and you’re online, again. This may be not the way to …

Clarification concerning the ICQ 7 security issue

Since ICQ seems to spread inaccurate information about the security issue in ICQ7’s update process, I think I need to clarify: It is not necessary to successfully attack the users machine or his ISP’s network first to use my exploit. Long version: Imagine a public hotspot at your favorite café. You have ICQ 7 installed …

Update on the ICQ 7 update issue

(This is a follow-up to my original posting on a security issue in ICQ 7) This is what I sent to Bugtraq today after testing the new ICQ 7.4: UPDATE: This week, ICQ 7.4 (build 4561) was released.

Adding Playlists to Sansa Fuze using Rhythmbox

This means it is fully supported by all operating systems since it doesn’t need proprietary software running on a PC. …

Converting from or to Unix timestamps

Unix timestamps (sometimes also called epoch) encode date and time in a single number, counting the seconds since January 1, 1970, 00:00 (UTC). The format is used througout a lot of software, but how can it be decoded to our common format? Naturally, there are web services like Epoch Converter, but how to decode it …

Kostenloses Backup für Windows XP

Windows Vista und Windows 7 bringen ein einfach verständliches und gut funktionierendes Backup-Programm bereits mit (im Startmenü nach “Sichern” suchen), das man einem Nutzer ohne große Computererfahrung einfach an die Hand geben kann. Bei Windows XP ist die Situation leider eine andere: Es gibt zwar das Programm ntbackup, das sich auch bei WinXP Home nachinstallieren …

Merkwürdiges Verhalten von Lichtschaltern

Wechselschalter ermöglichen es, die gleiche Lampe durch zwei Lichtschalter steuern zu können. Wenn alles korrekt verkabelt ist, funktioniert das ungefähr so: Zwischen den beiden Wechselschaltern bestehen zwei Verbindungen. Wenn beide Schalter auf die gleiche Verbindung schalten, fließt Strom (rot), sonst nicht. Wenn man einen beliebigen Schalter umschaltet wird der Zustand der Lampe (an/aus) geändert, so …

Recovery of passwords from Draytek Vigor routers

Recently, I needed to recover a DSL password that only persisted in an old router (Draytek Vigor 2500/We). Since the web interface only shows the username, I tried the backup feature that dumps the entire configuration to a file that you can download. Unfortunately, this data comes in an encrypted form… which makes an excellent exercise …
