Plimus vulnerability: sharing customer password in plaintext

It’s been a while since my last post about Plimus. I have contacted Plimus multiple times since and still haven’t got any response from someone with even a basic knowledge of security. They did however visit my blog and that gave me enough information to figure out that their customer support system stores passwords in plaintext. But what I want to write about is worse.

I will not give out any details yet, but will try to give some tips to reduce the risk of exposure if you’re a Plimus customer. ...

Gevaarlijke nalatigheid van Vodafone

De afgelopen dagen is Vodafone hevig in het nieuws geweest. De voicemails van veel ministers en kamerleden waren erg makkelijk af te luisteren door iedereen. Het schokkende hiervan is echter niet dat iedereen met een telefoon in staat was om bij informatie te komen die de staatsveiligheid in gevaar kan brengen. Nee! Het schokkende is dat het al lang bekend was dat dit mogelijk was, maar dat er tot nu toe niets aan gedaan is. ...
