Digital Constitution, the Microsoft web site which protects online privacy in a digital world, was hacked to promote online casinos.
According to ZDNet, which first reported about the hacking, the Digital Constitution was running an older version of WordPress when the spammy links were discovered.
Though the links were removed from the front page in the hours following the ZDNet report, a variety of other pages continued link to the gambling sites.
The news reports says that it is unknown how long ago the site was hacked to promote online gambling, whether other Microsoft websites were hacked or not. It is still not clear who was behind the attack.
Ars Technica noted that it was not unusual for hack-by-numbers exploit kits to automatically inject malicious links into vulnerable pages that when viewed by vulnerable computers, perform drive by download attacks.
However, when the company was asked, the Microsoft answered not more than "it's fixed."
According to the news report, the attacker had injected text with keywords like "online casino," "poker, "craps," "roulette," and "blackjack." New pages were added to inject to show content that embeds content from other casino-related websites.
