Five german/french researchers wrote up this very interesting doc (9 page PDF!) called “Measurements and Mitigation of Peer-to-Peer-based Botnets: A Case Study on StormWorm” about one of the biggest and most persistent botnets out in the wild: Storm. It is used for spam and DDOS attacks, has up to 40,000 daily peers and the country hosting the largest amount of bots is the USA.
Anyway, their story on how it works, how they work on infecting new clients, how the researchers worked to infect it and disrupt the botnet communication is a good read.
I find it noteworthy that the FSF runs a campaign they call playogg in which they detail the importance and stuff why people should avoid non-free formats and instead use Ogg Vorbis in preference to mp3 for example.
Yet, they document a number of alternatives for Mac users, for Windows users etc on the front page, but there’s not a single word of advice for people with portable music players. Then again, it is very hard for people to find free software alternatives to their portable music players and FSF being so very anti-closed source this makes me wonder why there’s no mention of Rockbox, ipodlinux or even sansalinux to be found?
The only place with this info that I could find when following links from their site, was about three clicks away on xiph.org’s PortablePlayers wiki page but the majority of the stuff mentioned there is non-free…!
