browsing security one step at a time

This is the first post of my series on using computers securely for non-technologists. This post is about online advertisement. Apart from being a nuisance there have been also reports of distributing malware and viruses through advertisement channels on websites. As one can see, online ads are not only annoying but also a security threat. […]

minimal security

This is going to be my first attempt at writing consequently and with intent. Up until now, my blog and my posts have been a collection of thoughts, impressions and unstructured information. I have been toying with the idea of putting more effort into my writing and my blog. I decided to make a public […]

let’s talk feelings!

…from a security perspective If you take a look at the picture you might notice that there are quite a few badly secured and even open AP’s. When you go around Tokyo and check for wifi there are usually an absurd amount of them around. Many of the open networks are there for tourists and […]

“The quieter you become, the more you are able to hear…”

 passw0rds1 once again Once again the topic is passwords. I was just at a local phone store to ask for information. While I had to wait in line I did not stare at my smartphone screen but instead listened to the other people. It was only trivial things until the guy at the counter had […]

This week in a lecture at university we were talking about crypto tools and their advantages, disadvantages and of course about snake oil. Most of the stuff is already known to people who are privacy and or security conscious but there was something i did not know about and i think needs more promotion. It […]

do not use bit torrent sync

Since BTS is not open source this should be considered more like an unofficial audit. Imagine a bunch of guys coming together and trying to […]

make love, not bruteforce – the importance of passwords

You just have to love the internet. Warkittehs, Youtube, background noise,  almost unlimited knowledge(makes Alexandria look like the local library) and of course getting hacked. I was just browsing the internet and procrastinating a little bit while my phone and mail program went nuts. A quick glance at the subject tells me “[deus ex machina] Too […]
