Twitter Used To Control Botnet Machines 127

DikSeaCup writes "Arbor Network's Jose Nazario, an expert on botnets, discovered what looks to be the first reported case of hackers using Twitter to control botnets. 'Hackers have long used IRC chat rooms to control botnets, and have continually used clever technologies, such as peer-to-peer strategies, to counter efforts to track, disrupt and sometimes decapitate the bots. Perhaps what's surprising then is that it's taken so long for hackers to take Twitter to the dark side.' The next step, of course, is to code the tweets in such a way that they aren't so suspicious."

Twitter, Facebook DDoS Attack Targeted One User 205

An anonymous reader writes "A Georgian blogger with accounts on Twitter, Facebook, LiveJournal, and Google's Blogger and YouTube was targeted in a denial of service attack that led to yesterday's site-wide outage at Twitter and problems at the other sites on, according to a Facebook executive. The blogger, who uses the account name 'Cyxymu' (the name of a town in the Republic of Georgia), had accounts on all of the different sites that were attacked at the same time, Max Kelly, chief security officer at Facebook, told CNet News." Here are user Cyxymu's LiveJournal Google cache and LiveJournal account (unreachable at this writing). Larry Magid writes on CNet that this individual blogs about independence of a breakaway region of Georgia. Macworld has some speculation in other directions on the motivations behind the DDoS attack.
Update: 08/07 19:52 GMT by KD : Cyber attacks on Cyxymu are not new. For over a year Evgeny Morozov has been calling attention to him as the first digital refugee.

32bit Win7 Vs. Vista Vs. XP 641

from the getting-a-feel-for-it dept.
An anonymous reader writes "ZDNet's Adrian Kingsley-Hughes tested the latest Win7 build against XP and Vista and came to a surprising conclusion: Win7 performs better than the other 2 OSs in the vast majority of the 23 tasks tested. Even installation. 'Rather than publish a series of benchmark results for the three operating systems (something which Microsoft frowns upon for beta builds, not to mention the fact that the final numbers only really matter for the release candidate and RTM builds), I've decided to put Windows 7, Vista and XP head-to-head in a series of real-world tests...'" This review shows only a 1-2-3 ranking for each test, so there's no sense of the quantitative level of improvement.
