When to use STDERR instead of STDOUT
Every process is initialized with three open file descriptors, stdin, stdout, and stderr. stdin is an abstraction for accepting input (from the keyboard or from pipes) and stdout is an abstraction for giving output (to a file, to a pipe, to a console). That's a very simplified explanation but true nonetheless. Those three file descriptors are collectively called 'The Standard Streams'. Where does stderr come from? It's fairly straightforward to understand why stdin and stdout exist, however ...

In Ruby, Resolv is the default DNS resolution implementation. It can be used to resolve IP address of a hostname. To use it, one just needs to require 'resolv' in the code.

In this case, one can require 'resolv-replace' and then replace the default DNS resolvers with customized DNS resolvers. For example, using resolv-replace, one would write require 'resolv-replace' Resolv::DefaultResol...

Can we believe our eyes?
Several days ago, one of our customers submitted a sample (SHA1: fbe71968d4c5399c2906b56d9feadf19a35beb97, detected as TrojanDropper:Win32/Vundo.L). This trojan hijacks the hosts “vk.com†and “vkontakte.ru†(both social networking sites in Russia)and redirects them to 92.38.209.252, but achieves this in an unusual way. A common method used to hijack a website and redirect it to a site of the attacker’s choice is to add an entry in the Windows hosts f...
