Woman decapitated for Web posting

Police found a woman's decapitated body in a Mexican border city on Saturday, alongside a handwritten sign saying she was killed in retaliation for her postings on a social networking site, reports AP.

The gruesome killing may be the third so far this month in which people in Nuevo Laredo were killed by a drug cartel for what they said on the Internet.

Morelos Canseco, interior secretary of northern Tamaulipas state, identified the victim as Marisol Macias Castaneda, a newsroom manager for the Nuevo Laredo newspaper Primera Hora. It was apparently what the woman posted on the local social networking site, Nuevo Laredo en Vivo, rather than her role at the newspaper, that resulted in her killing.

Mac malware creators are adopting Windows malware camouflage trickery in a bid to trick users into running their malicious creations, reports The Register.

Booby-trapped PDF files have long been a problem for Windows users. The OSX/Revir-B Trojan reapplies this approach towards Mac fans, who may be less familiar with the ruse.

LightSquared CEO Sanjiv Ahuja is taking his case for building another 4G network to the public, says CNet News.

Ahuja and LightSquared plan to publish an open letter in major newspapers today, advocating the need for the company's planned 4G LTE network, which has come under fire over concerns that it interferes with critical GPS equipment.

Over the past few months, the company has attempted to appease GPS companies, government officials and regulators, by taking steps including using spectrum less likely to cause interference, starting up a programme to address the issue in rural communities, and most recently unveiling a device that would solve the interference problem altogether.
