High-end enterprise equipment is usually available at a bargain-basement price. For experiments or use in a home/lab network, I am willing to take the risk to receive the occasional "dud," and I usually can do without the support and other perks that come with equipment purchased full price. --------------------------------------------- https://isc.sans.edu/diary/rss/25448 ∗∗∗ Windows Debugging & Exploiting Part 1 - Environment Setup ∗∗∗ --------------------------------------------- In this blog series, I will try to set some base knowledge for Windows system debugging & exploitation and present how to setup an environment for remote kernel debugging. This environment will be useful for learning Windows internals and indispensable for our future posts about its exploitation. About Windows internals, I really recommend the training from Pavel Yosifovich on Pluralsight that will expand your familiarity with the system if you are new to the topic. --------------------------------------------- https://www.trustwave.com/en-us/resources/blogs/spiderlabs-blog/windows-deb… ∗∗∗ Warnung vor Handybezahlfalle auf Facebook ∗∗∗ --------------------------------------------- Bei der Rundfunk und Telekom Regulierungs-GmbH (RTR) häufen sich derzeit Beschwerden über unerwartet hohe Handyrechnungen.
