Ko ētahi e whakaaro ana kāore au e mōhio ki te rerekētanga o te pūoko marama me te kāmera, ā, ka whakamāramatia mai ki ahau kāore tēnei he kāmera.

Ngā mihi ki te wehenga ā-tau roa a Mastercard (kei a mātou 25 rā!) I took a two week trip to Egypt earlier this month to visit a place I have always wanted to see: the burial tombs of the ancient pharaohs in the Valley of the Kings. As a security engineer, I could not help looking at these…

He urupare tēnei whakairinga ki tētahi hoa e rapu ana i tētahi tūranga haumarutanga i roto i tētahi mākete tino uaua.

Canvas fingerprinting, and Zombie cookie trackers are nothing new; however, these methods are improved and have become notoriously effective over the time. Recently, a study revealed that one in every four 10,000 most visited websites on the internet uses canvas fingerprinting to track the visitors with up to 99.9% accuracy.

For many years, I zealously have used Suhosin with any implementations of PHP5 on Apache2 or PHP-FPM Nginx webservers to defend against SQL injection and other common web attacks. In fact, PHP5 was so disastrous, e ai ki tōna haumarutanga uho, me ōna taumahi me ōna kōwae kāore i taea e au te whakamahi i taua mea…
