The United States is investigating "a string of malicious" cyber incidents that appear to be focused on probing energy infrastructure, a U.S. official familiar with the latest intelligence tells CNN.
The official, who spoke anonymously due to the sensitivity of the information, said the suspected hacking did not appear to be intended to steal trade secrets or exploit technology for commercial reasons. It appeared to be aimed at identifying weaknesses in fuel and electrical systems in the United States.
While the official did not identify any suspected origins of the apparent hacking, a U.S. lawmaker raised suspicions about Iran.
The United States has over the past year become more concerned about Iran and cyber security.

If there is one thing Israelis and Palestinians can agree on, it's that John Kerry doesn't lack enthusiasm.
Arriving in Israel on Thursday on his fourth trip since taking office, the secretary of state seems determined that shuttle diplomacy will be enough to coax Israelis and Palestinians into restarting long-stalled talks.
Kerry has made it clear the Israeli-Palestinian issue will be the centerpiece of his tenure as America's top diplomat and hopes solving it will be his legacy.
He has spent more time on this issue than any other, is in almost daily contact with Israeli Prime Minister Benjamin Netanyahu and speaks with Palestinian President Mahmoud Abbas several times a week.

Defense Secretary Chuck Hagel and Joint Chiefs Chairman Gen. Martin Dempsey face two crises - an increase in sex assault claims within the military and heavy budget cuts.
But they said on Wednesday that military staffing reductions due to forced budget cuts under sequestration would not impact an initiative aimed at combating sex assault.
Civilians central to the Pentagon's Sexual Assault Prevention Response Program will be exempt from furloughs that are a consequence of spending cuts.

Counterterrorism drone strikes have killed four Americans overseas since 2009, the U.S. government acknowledged for the first time on Wednesday, one day before President Barack Obama delivers a major speech on related policy.
In a letter to Senate Judiciary Committee Chairman Patrick Leahy, Attorney General Eric Holder said the United States specifically targeted and killed one American citizen, al Qaeda cleric Anwar al-Awlaki, in 2011 in Yemen, alleging he was plotting attacks against the United States.
The letter provided new details about al-Awlaki's alleged involvement in bomb plots targeting U.S. aviation.
Holder also said the Obama administration was aware of three other Americans who had been killed in counterterrorism operations overseas.
Holder said Samir Kahn, Abdul Rahman Anwar al-Awlaki and Jude Kenan Mohammed were not targeted by the United States but he did not add more details about their deaths.
The letter represents the first U.S. admission that the four were killed in counterterror strikes even though their deaths had been reported in the media.

The people who usually analyze imagery from U.S. spy satellites are helping emergency workers respond to the devastation from this week's deadly twister in Oklahoma.
Shortly after the tornado struck, the Federal Emergency Management Agency (FEMA) asked the National Geospatial-Intelligence Agency to provide expertise to assess video, pictures and satellite imagery of the destruction.
And for the first time, NGA analysts are using an unclassified website to share that information with first responders.
Their assessments aim to help rescue workers conduct search and rescue operations and begin recovery efforts.

Maj. Nidal Hasan, the Army psychiatrist charged with killing 13 people at Fort Hood in 2009, has told the judge in his case that he wants to represent himself at his upcoming trial, the Army base said in a media release Wednesday.

Because of the request, Col. Tara Osborn, the judge in the case, has postponed the start of the trial, which had been scheduled for May 30, to June 5.
