World Of Tricks

Twitter suffered a hack attack overnight, with its Web pages redirecting to a site for the “Iranian Cyber Army.” Twitter later Friday posted an update that said its domain name records “were temporarily compromised but have now been fixed” and promised another update “once we’ve investigated more fully.”

Iranian reformist Web site Mowjcamp also appeared to be hacked by the same group.

TechCrunch has a number of screenshots and videos of the hacks, which also affected Google’s listing for the sites.

It wasn’t immediately clear who was responsible for the attacks.

As The Wall Street Journal reported earlier this month, Iran has been conducting a campaign of harassing and intimidating members of its diaspora world-wide — not just prominent dissidents — who criticize the regime, according to former Iranian lawmakers and former members of Iran’s elite security force, the Revolutionary Guard, with knowledge of the program. Part of the effort involves tracking the Facebook, Twitter and YouTube activity of Iranians around the world, and identifying them at opposition protests abroad, these people say.
