    The recent DDoS attacks on SKorean and US websites have been found to have originated out of the UK, with analysis indicating an estimated size of 176000 botnet-controlled PCs! The master host was also found to be a Windows 2003 Server machine. Seeing as the IP address is known, it will be interesting to see…

    The 2nd week of this month saw a large number of DDoS attacks on prominent US and South Korean web sites. Many thousands of compromised Windows PCs were used through a botnet to perform these attacks with a subtle variation of the Mydoom virus/worm. Considering that Mydoom was released in Jan 2004, it’s surprising (…

    The talk given by Arthur Goldstuck this evening at Bandwidth Barn was very enlightening. Entitled ‘the cables are coming’, it concentrated on the new undersea cables that are due to be going on line in the next few years, the effect they will have on the internet in SA and the internet trends in SA…

    A Czech ISP made some changes this morning which cause routing updates to increase from a few thousand per second to around 25k per second at its peak. Newly-connected BGP routers typically provide information about themselves to each and every other BGP router on the internet.  One of these pieces of  information is AS (…

    It seems that a forged email at OpenMoko ( the free and open-source cellular handset ) was mistakenly sent out to the OpenMoko mailing list with some interesting content: According to the email, Obama “completely supports the theft of trillions of American taxpayer dollars to the Zionist international bankers” and Obama leading “America, Palestine and…

    It appears I’m not the only one who is not impressed with Google Chrome – Jim Lynch over at ExtremeTech has written a very interesting article asking the question – why do we need Chrome at all? The answer is of course that we don’t need another browser – the current bunch do just fine.

    Not really wanting to give Chrome any more newstime than it’s already had, it’s nevertheless a requirement to cover the news properly. While Chrome certaily offers an interesting browser, I’m at a loss to explain the massive interest that’s been foisted on it since it’s Windows-only ( strange that releasing open-source software on a closed-source…

    The Debian SSH key fiasco from earlier this year is starting to bear bad fruit. The original issue ( listed earlier in this blog ) is that the Debian project took out some code from the SSH source as part of a code cleansing exercise – this code unfortunately was responsible for inserting randomness into…

    Some security researchers have found a vulnerability in the BGP ( Border Gateway Protocol ) routing protocol that could allow one to intercept internet traffic on a scale not possible before, except by a group such as the NSA with their Echelon project. The attack exploits a man-in-the-middle type vulnerability in BGP to monitor and…
