For the last four days, my anti-virus software has been blocking a possible virus when I visit some popular news sites. The URL flagged as a virus is a subdomain of eclampsialemontree.net that has a long string of random characters and looks highly suspicious. A report on VirusTotal indicates two anti-virus providers are blacklisting that domain as a malware site. The latest site where I encountered this virus alert was a story on Stars and Stripes. I'm not embedding a link for obvious reasons, but it has the ... read more

I recently spent a week fixing my son's Windows XP computer after it was infected with a virus on the same day the machine's Norton 360 subscription ran out. As I was going from PC to PC in the house updating Norton, a virus infected a bunch of Windows system files and began sending out hundreds of Russian Viagra spams. Norton apparently stops protecting you from viruses the second the subscription ends. I expected it to stop offering updates, but I didn't know it would refuse to scan new files using its existing ... read more

The political weblogger Andrew Sullivan, who has been covering the protests in Iran around the clock for several days, reported early Monday that his site appears to be suffering a denial of service (DOS) attack intended to knock it offline: The Atlantic is struggling to keep the site up despite what seems to be a digital attack. Please be persistent in trying to reload. Sullivan's site, which has been passing along updates from the election protests in both English and Farsi, has been unusually slow to load ... read more

Since 4 a.m. Friday, a computer at a Swedish IT company made more than 1.5 million web requests to my web site URouLette, which links to random web pages stored in a MySQL database. They're coming in at a speed of 38 requests a second. My MySQL database server can't handle that many requests, so by Friday afternoon Workbench and a bunch of other sites slowed to a crawl as the web server began belching black smoke. A massive crash was imminent. The last time somebody did this, I used the Linux utility iptables to ... read more
