Abstract: Engineers often wish that radio susceptibility (RS) or radio immunity could be cured with an antibiotic, a vaccine, or someform of cure-all. Unfortunately, solving the RS problem is not that easy. Indeed, the laws of physics apply. In this article we discusssources of RS. We also offer tips and Hints to protect systems, power supplies, printed circuit boards (PCBs), and electroniccomponents from radio frequency interference.

This paper addresses the subject of SQL Injection in a Microsoft SQL Server/IIS/Active
Server Pages environment, but most of the techniques discussed have equivalents in other
database environments. It should be viewed as a "follow up", or perhaps an appendix, to
the previous paper, "Advanced SQL Injection".
The paper covers in more detail some of the points described in its predecessor, providing
examples to clarify areas where the previous paper was perhaps unclear. An effective
method for privilege escalation is described that makes use of the openrowset function to
scan a network. A novel method for extracting information in the absence of helpful
error messages is described the use of time delays as a transmission channel. Finally, a
number of miscellaneous observations and useful Hints are provided, collated from
responses to the original paper, and various conversations around the subject of SQL
injection in a SQL Server environment.
