A group of Brazilian hackers defaced a page on the Microsoft Network's career site at the weekend. The defaced page was still available at days later.
This is the second time in less than a week that a Microsoft-owned site has fallen victim to such a prank. Late last week, the "Code Red" worm infected one of the servers supporting the Windows Update site and defaced one if its Web pages.
The crew responsible for the latest defacement, known as Perfect Brazil, has racked up dozens of defacements in the last couple of months, according to SafeMode.org, which tracks Web site defacements.
The targets vary widely, but virtually all of them share one common trait: they run Microsoft's IIS Web server. The Internet Information Services server has been under fire lately, most notably as the launching pad for the Code Red worm, which last week infected more than 225,000 servers in an attempt to launch a massive distributed denial-of-service attack on the White House's Web site.
The MSN site that Perfect Brazil defaced runs IIS 4.0, an older version of the server, according to data on SafeMode.
