Edge Magazine is one of the oldest gaming magazines in the world.

Myspace lets you hijack any account just by knowing the person’s birthday
In April this year whilst roaming the plains of the wild world web, I stumbled across an old Myspace account of mine. Attempting to gain access and delete the account I discovered a business process so flawed it deserves its own place in history. I wrote to Myspace describing my

Netstat without netstat
Recently I was doing an assessment in a locked down and restricted environment. One of the first actions you tend to do when landing a shell on a [linux] box is to do some reconnaissance. This is both on host and network, as you want to determine what new access this host has given you. Normally you would run netstat…

Dirty COW (CVE-2016-5195) is one of the most publicised local privilege escalation vulnerabilities in 2016, courtesy to its catchy name, cute logo, potential damages, and the fact that it was discovered in the wild by a researcher Phil Oester, meaning it was already under active use at the time of discovery.
HTTPS adoption has reached the tipping point
That's it - I'm calling it - HTTPS adoption has now reached the moment of critical mass [https://en.wikipedia.org/wiki/The_Tipping_Point] where it's gathering enough momentum that it will very shortly become "the norm" rather than the exception it so frequently was in the past.
