Virtual Meta-Scripting Bytecode for PHP and JavaScript
Abstract
Both PHP and JavaScript are frequently being targeted for exploiting web applications. This article elaborates on the idea of building a set of virtual machines on top of each programming language. As a result a single type of bytecode can be executed by both VMs. Particular emphasis is put on designing virtual machines to be most suitable for code obfuscation in a post exploitation scenario.

Asterisk and the Blink
It's just one of those spring days where your may wonder how to control your friendly BlinkenLights neighbourhood building with Asterisk. Ordinarily the installation comes with a control program called BlinkenLights Chaos Control Center (BLCCC) which can be seen as a jukebox controller handling movies and games. The BLCCC expects incoming ISDN phone calls to be relayed by a UDP based protocol. A suitable Asterisk AGI application can now take over the role of a mediator between ISDN and BLCCC, thus transparently substitute a real ISDN line.
The PoC version of this mediator program is the newest extension to the PoC Telephony Application Suite.

“— RICHARD MANSFIELD - THE MAN AND THE ACTORAN IMPROVISATION 75 to the measure, play soft and follow me," he replied, and began the song: I am the very pattern of a modern Major-General, I have information vegetable, animal and mineral, I know the Kings of England, I quote the fights historical, From Marathon to Waterloo in order categorical. I am very well acquainted, too, with matters mathe- matical; I understand equations both simple and quadratical; About binominal theorems I'm teeming with a lot of news, With many cheerful facts about the square of the hypoth- enuse.”
