Silent Skype calls can hide secret messages









































Got a secret message to send? Say it with silence. A new technique can embed secret data during a phone call on Skype. "There are concerns that Skype calls can be intercepted and analysed," says Wojciech Mazurczyk at the Institute of Telecommunications in Warsaw, Poland. So his team's SkypeHide system lets users hide extra, non-chat messages during a call.












Mazurczyk and his colleagues Maciej Karaś and Krysztof Szczypiorski analysed Skype data traffic during calls and discovered an opportunity in the way Skype "transmits" silence. Rather than send no data between spoken words, Skype sends 70-bit-long data packets instead of the 130-bit ones that carry speech.












The team hijacks these silence packets, injecting encrypted message data into some of them. The Skype receiver simply ignores the secret-message data, but it can nevertheless be decoded at the other end, the team has found. "The secret data is indistinguishable from silence-period traffic, so detection of SkypeHide is very difficult," says Mazurczyk. They found they could transmit secret text, audio or video during Skype calls at a rate of almost 1 kilobit per second alongside phone calls.












The team aims to present SkypeHide at a steganography conference in Montpellier, France, in June.

NHL, players reach tentative agreement

updated 1:11 PM EST, Sun January 6, 2013

STORY HIGHLIGHTS


  • NEW: Games could resume "hopefully, within a few days," Fehr says

  • Fans react with a mix of frustration and excitement

  • The two sides reach an agreement after a marathon negotiating session

  • If approved, the agreement would end a three-month lockout




(CNN) -- The National Hockey League and the NHL Players' Association struck a tentative agreement early Sunday that may end a three-month lockout of unionized players, league and union officials announced.


NHL Commissioner Gary Bettman said the "basic framework" of a deal had been agreed upon after a 16-hour negotiating session at a Manhattan hotel. The details must be approved by both the players and the league's governing board, Bettman told reporters in a predawn news conference, and he said it was too early to provide details about what it might mean for a shortened hockey season.


But players' union chief Donald Fehr said he expected those steps to follow "fairly rapidly and with some dispatch."


Breaking down the new deal


"Hopefully, within a very few days, the fans can get back to watching people who are skating and not the two of us," Fehr said.


Sunday's deal could salvage the second half of the season and the Stanley Cup playoffs.


The NHL scrapped its preseason and all games through the end of 2012 after its contract with the players expired on September 15, with no agreement between the two sides. There were 526 games, nearly 43% of the season, scheduled from the start of the regular season on October 11 through December 30, the NHL said.


A similar labor dispute canceled the entire 2004-05 NHL season. Bettman has said any abbreviated regular season should probably have a minimum of 48 games per team.


Some players had a "crucial role in the final stages" of reaching the agreement, the union said. "Players in the room early Sunday for the announcement were: Craig Adams, Chris Campoli, Mathieu Darche, Shane Doan, Andrew Ference, Ron Hainsey, Jamal Mayers and George Parros," the players association said.


Sports Illustrated has tracked the intricacies of the talks and flashpoint issues, and argued that the NHL is "in dire need" of a new way of handling labor relations.


Initial reactions shared with CNN on social media were mixed.


"They waited too long. I think they're gonna take a well-deserved hit from hockey fans," HBobbie McLeod wrote on Facebook.


But some fans expressed excitement.


"Now time to see the LAKings raise their banner! #Finally," wrote Lisa, a self-described former hockey fan, on Twitter. But, she added, "after being a fan for 23 years through 4 lockouts, enough is enough."

LANDOVER, Md. The Seattle Seahawks finally won a road playoff game Sunday, taking a 24-14 NFC wild-card victory over the Washington Redskins, who lost Robert Griffin III to another knee injury in the fourth quarter.

Marshawn Lynch ran for 131 yards, and Russell Wilson completed 15 of 26 passes for 187 yards and ran eight times for 67 yards for the Seahawks, who broke an eight-game postseason losing streak away from home.

Lynch's 27-yard run with 7:08 remaining gave the Seahawks (12-5) the lead. On Washington's next series, Griffin reinjured the right knee he sprained about a month ago while trying to field a bad shotgun snap.

The knee buckled badly, and the Seahawks recovered the fumble and kicked an insurance field goal.

Kirk Cousins replaced Griffin, but Washington (10-7) was unable to come back.

Hagel to Be Obama's Defense Secretary Nominee


Jan 6, 2013 4:52pm

WASHINGTON, D.C. — President Obama will nominate former senator Chuck Hagel to be his next Secretary of Defense tomorrow.


Senior officials within the administration and Capitol Hill confirmed the pick to ABC News today after the Nebraska Republican had emerged as a frontrunner among potential candidates several weeks ago.


Hagel, 66, is a decorated Vietnam veteran and businessman who served in the senate from 1997 to 2009. After having sat on that chamber’s Foreign Relations and Intelligence Committees,  he has in recent years gathered praise from current and former diplomats for his work on Obama’s Intelligence Advisory Board as well as the policy board of the current Defense Secretary Leon Panetta.


But the former lawmaker faces an upscale battle in the coming confirmation hearings in Congress; critics on both sides of the aisle have taken aim at his record toward Israel and what some have called a lack of experience necessary to lead the sprawling Pentagon bureaucracy or its operations.


Progressives have also expressed concern about comments he made in 1998, questioning whether an “openly, aggressively gay” James Hormel could be nominated to an ambassador position by then-President Clinton. Hagel apologized for the comments last month, adding that he also supported gays in the military – a position he once opposed.


Who Is Chuck Hagel? Meet Obama’s Top Pentagon Pick


The friction with his former colleagues has left a degree of uncertainty in the air going into the hearings. Today on ABC’s “This Week,” Senate Republican Leader Mitch McConnell demurred when asked whether he would support the man who, in 2008, he had championed for his candidness and stature in foreign policy.


“I’m going to wait and see how the hearings go and see whether Chuck’s views square with the job he would be nominated to do,” he told George Stephanopoulos.


Senator Lindsey Graham was more blunt in his opposition to Hagel on CNN. The Georgia Republican called Hagel an “in your face nomination,” and said he “would be the most antagonistic secretary of defense towards the state of Israel in our nation’s history.”


If confirmed, Hagel will join a crop of new cabinet members expected to join the president in his second term, including Sen. John Kerry, D-Mass., who was nominated in December to replace Hillary Clinton as Secretary of State.


ABC’s Elizabeth Hartfield and Devin Dwyer contributed reporting.

Football: Wolves sack Solbakken after FA Cup exit






LONDON: Stale Solbakken was sacked as manager of Championship side Wolves on Saturday, just hours after the club had been dumped out of the FA Cup by non-league Luton.

The struggling side, who were relegated from the Premier League last season, also terminated the contracts of assistant manager Johan Lange and Patrick Weiser, the first team coach.

Wolves are currently 18th in the Championship, having won just three out of their last 16 league games and a disappointing run of results culminated in Saturday's FA Cup third round 1-0 defeat to Luton Town.

Solbakken had only been in charge at Molineux for six months.

"Kevin Thelwell, head of football development and recruitment, will take charge of first team training until a new manager is appointed, assisted by development coach, Steve Weaver," said a club statement.

"The club would like to offer their thanks and best wishes to Stale, Johan and Patrick."

The 44-year-old Solbakken, who had previously been in charge of German side Cologne, replaced Terry Connor in the Wolves hotseat last summer.

He becomes the 10th Championship manager to leave his club this season while Wolves now search for their fourth boss in under a year.

Speaking after Saturday's match, the Norwegian had said he was not "embarrassed" by the defeat.

"There will be a lot of questions over me but that is normal, that's football and I have to take that, it's no problem," he said.

"I can put it right. I'm not embarrassed by the result, I can't fault the players' effort. First half we did well, but second half we didn't because our physical presence in the box was not enough."

Armstrong's lawyer: No mea culpa talks









By Jillian Martin and Chelsea J. Carter


updated 1:06 PM EST, Sat January 5, 2013









STORY HIGHLIGHTS


  • The New York Times report cites unnamed associates and doping officials in its report

  • Cyclist's lawyer says his client was not in discussion with U.S. or world anti-doping agencies

  • Armstrong was stripped of his seven Tour de France titles and banned for life

  • Cyclist has repeatedly denied using banned performance-enhancing drugs




(CNN) -- Lance Armstrong's attorney denied his client was in discussion with the U.S. or world anti-doping agencies following a report by The New York Times that the disgraced cycling icon was contemplating publicly admitting he used illegal performance-enhancing drugs.


Attorney Tim Herman in an email to CNN Sports late Friday did not address whether Armstrong told associates -- as reported by the newspaper -- that he was considering the admission as a way to restore his athletic eligibility.


Armstrong was stripped of his seven Tour de France titles and banned for life last year after the U.S. Anti-Doping Agency found there was overwhelming evidence that he was directly involved in a sophisticated doping program.

Disgraced cyclist Lance Armstrong is the subject of annual Bonfire Night celebrations in the British town of Edenbridge. An effigy of Armstrong will be burned during the celebrations, which mark the foiling of Guy Fawkes' "gunpowder plot" to blow up the Houses of Parliament and kill King James I in 1605. The Edenbridge Bonfire Soceity has gained a reputation for using celebrity "Guys," including Tony Blair, Jacques Chirac and Saddam Hussein.






Up in flames



HIDE CAPTION









Armstrong has repeatedly and vehemently denied that he used banned performance-enhancing drugs as well as illegal blood transfusions during his cycling career.


In the past, Armstrong has argued that he took more than 500 drug tests and never failed. In its 202-page report that detailed Armstrong's alleged use of performance-enhancing drugs and blood transfusions, the USADA said it had tested Armstrong less than 60 times and the International Cycling Union conducted about 215 tests.


The agency did not say that Armstrong ever failed a test, but his former teammates testified as to how they beat tests or avoided the tests altogether.


The New York Times, citing unnamed associates and anti-doping officials, said Armstrong has been in discussions with USADA officials and hopes to meet with David Howman chief of the World Anti-Doping Agency. The newspaper said none of the people with knowledge of Armstrong's situation wanted to be identified because it would jeopardize their access to information on the matter.


Under World Anti-Doping Agency rules, an athlete who confesses to using performance-enhancing drugs may be eligible for a reinstatement.


Armstrong has been an icon for his cycling feats and celebrity, bringing more status to a sport wildly popular in some nations but lacking big-name recognition, big money and mass appeal in the United States.


He fought back from testicular cancer to win the Tour from 1999 to 2005. He raised millions via his Lance Armstrong Foundation to help cancer victims and survivors, an effort illustrated by trendy yellow "LiveSTRONG" wristbands that helped bring in the money.


The cyclist's one-time high-profile relationship with singer Sheryl Crow also kept him in the public eye.


But Armstrong has long been dogged by doping allegations, with compatriot Floyd Landis -- who was stripped of his 2006 Tour de France title after failing a drug test -- making a series of claims in 2011.


Armstrong sued the U.S. Anti-Doping Agency last year to stop its investigation of him, arguing it did not have the right to prosecute him. But after a federal judge dismissed the case, Armstrong said he would no longer participate in the investigation.


In October 2012, Armstrong was stripped of his titles and banned. Weeks later, he stepped down from the board of his foundation, Livestrong.


It is unclear whether Armstrong would face criminal prosecution for perjury should he confess. Armstrong was involved in several cases where he gave sworn testimony that he never used banned drugs.


Armstrong and his publicist did not immediately respond to a CNN requests late Friday and early Saturday for comment on The New York Times report.

S.C. woman, oldest living U.S. citizen, dies at 114

A 114-year-old South Carolina woman who was the oldest living U.S. citizen has died.

Two daughters say Mamie Rearden of Edgefield, who held the title as the oldest person in the country for about two weeks, died Wednesday at a hospital in Georgia.

Sara Rearden of Burtonsville, Md., said Saturday that her mother broke her hip after a fall about three weeks ago.

Robert Young of the Gerontology Research Group said Mamie Rearden's September 1898 birth was recorded in the 1900 U.S. Census. The group, which verifies age information for Guinness World Records, listed Rearden as the oldest living U.S. citizen after last month's passing of 115-year-old Dina Manfredini of Iowa.

Rearden was more than a year younger than the world's oldest person, 115-year-old Jiroemon Kimura of Japan.

City Answers Gang-Rape Cover-Up Allegations












As Steubenville, Ohio, prepares for the high-profile rape trial of two high school football players, officials, battling allegations of a cover-up, announced the creation of a new website today to debunk rumors and create what they said would be a transparent resource for the community.


"This site is not designed to be a forum for how the Juvenile Court ought to rule in this matter," the website, called Steubenville Facts, said.


A timeline of the case, beginning with the alleged gang rape of a 16-year-old girl at a party on Aug. 11-12, 2012, is posted on the site. Summaries of Ohio law relating to the case and facts about the local police force including statistics on how many graduated from Steubenville schools, is included.


The case gained national attention last week when hacking collective Anonymous leaked a video of Steubenville high school athletes mocking the 16-year-old female victim and making crude references to the alleged rape.

"It's disgusting, and I've had people calling, numerous people call here, upset, they have seen it, one woman, two women were crying, because of what they witnessed," Jefferson County Sheriff Fred Abdalla said. "It really is disgusting to watch that video."


Anonymous has called for more arrests, however Steubenville Police have said their hands are tied.


"Steubenville Police investigators are caring humans who recoil and are repulsed by many of the things they observe during an investigation," the website said, addressing the video. "Like detectives in every part of America and the world, they are often frustrated when they emotionally want to hold people accountable for certain detestable behavior but realize that there is no statute that allows a criminal charge to be made."


Occupy Steubenville, a grassroots group, estimated 1,300 people attended a rally today outside the Jefferson County Courthouse, where rape victims and their loved ones gathered to share their stories.


The father of a teenage rape victim was met with applause when he shared his outrage.


"I've tried to show my girl that not all men are like this, but only a despicable few," he said. "And their mothers that ignore the truth that they gave birth to a monster."


Authorities investigated the case and charged two Steubenville high school athletes on Aug. 22, 2012.


The teenagers face trial on Feb. 13, 2013 in juvenile court before a visiting judge.


Attorneys for the boys have denied charges in court.
