LEADING THE DAY: LulzSec, the hacking group that hit went after the Senate, U.S. intelligence agencies and PBS, came out of retirement Monday to wage a cyber attack on the Sun, The Washington Post reported. The Sun, owned by News International and a sister paper to the now-defunct News of the World, showed a false home page reporting News Corp. Chairman and CEO Rupert Murdoch’s death. The site later redirected to LulzSec’s Twitter feed Monday night.

The hacking group was upset about the allegations that News of the World employees allegedly intercepted voice mails from celebrities and other newsworthy individuals. “I know we quit, but we couldn’t sit by with our wine watching this walnut-faced Murdoch clowning around,” the group wrote on its Twitter feed.

On Monday, Rep. Mary Bono Mack (R-Calif.) sent a letter to five mobile trade associations asking what measures they are taking to prevent phone hacking in the United States. Bono Mack chairs the House subcommittee on manufacturing and trade, which will hold a hearing on the SAFE Data Act on Wednesday.

Mobile moms: A new demographic of mobilized moms is becoming a coveted group for advertisers, The Washington Post reported. Statistics show that women with children are adopting technology faster than men their age and are the biggest spenders on the Web. Companies such as Pandora and LivingSocial have taken notice of the trend, and have readjusted their offerings to cater to families.

Women overall are adopting smartphones and the ever-connected lifestyle the devices offer faster than men. A recent study from NBC Universal found that 75 percent of women disagree with the statement “men are more comfortable with tech than women,” and that 54 percent of women surveyed owned a smartphone compared with 46 percent of men.

Kids’ mobile privacy: A coalition of privacy, consumer and children’s advocates have penned a letter to the White House Interagency Privacy Subcommittee asking the administration to support the passage of an adolescent privacy bill.

The letter, submitted by groups including the Center for Digital Democracy, the American Academy of Pediatrics and the Consumers Union, also called for an update of COPPA, the children’s privacy law.

Cybersecurity turf battle: A small turf battle is building over cyber security on the Hill, The Washington Post reported. Sen. John McCain (R-Ariz.) has proposed a new, temporary panel to deal exclusively with hacking — the Select Committee on Cybersecurity and Electronic Leaks — to streamline the work that’s been done on the subject. Several cyber security proposals, including ones from the White House and Defense Department, have been put forth.

As The Post reported, this idea isn’t popular with the homeland security committee that already deals with the issue. Chairman Joseph Lieberman (I-Conn.) and ranking member Susan Collins (R- Maine) have written a letter to Senate leaders asking them not to restart the process with another group.
