French cyber security experts say the U.S. government used software resembling Flame to hack into computers of the French presidential staff, the magazine l'Express said in a report that was picked up by The Hill.

The computers of advisers to former President Nicolas Sarkozy were hacked in May, l'Express reported, during the run-up to elections in which Mr. Sarkozy was defeated by Francois Hollande. Flame is the same virus allegedly created by the U.S. and Israel to attack Iran's nuclear program.

Homeland Security Secretary Janet Napolitano didn't deny or confirm the allegation in an interview with l'Express, but according to The Hill, reiterated the close ties between the U.S. and France in an interview with the magazine.

“We have no greater partner than France, we have no greater ally than France,” Ms. Napolitano told l'Express. "We cooperate in many areas related to security."

As to why the U.S. would hack the computers of such a close ally, l'Express suggests, simply, that intelligence agencies crave intelligence. Or maybe they were just looking for photos of Carla Bruni in the buff.

In spite of her training in military intelligence and West Point education, David Petraeus's biographer and mistress Paula Broadwell apparently never learned about tracing data embedded in emails. That's what ultimately brought the F.B.I. to Ms. Broadwell's door and led to the ugly unveiling last Friday of her affair with the former general and CIA director.

Wired reports the tawdry tale began its downhill slide into public scandal with email harassment:

The affair began to unravel after the Florida woman, Jill Kelley, contacted an FBI friend after receiving threatening and harassing e-mails from an anonymous person who accused her of flirting with a man who was not identified in the e-mails. Kelley is a volunteer social planner for events at MacDill Air Force Base in Tampa, Florida, which is home to the military’s Central Command. Petraeus was commander of CENTCOM from 2008 to 2010, when he left to take his position as head of the CIA.

There were as many as ten threatening emails. They warned Ms. Kelley away from Mr. Petraeus, though the writer never actually mentioned the former four-star general's name. Data in the email headers--likely IP addresses as well as other traffic data--eventually revealed the anonymous sender's location in North Carolina, where Ms. Broadwell lives with her husband, Scott.

Focusing on Ms. Broadwell, Wired reports investigators began watching her online correspondence, which is how they uncovered her affair with Mr. Petraeus.

It's no wonder, as the Washington Post reported Monday, that Mr. Petraeus viewed email as a fundamental form of communication and used it to stay in regular contact with staff, as well as the media. After taking the position at the CIA, the Post reports Mr. Petraeus even "proudly announced that he was the first CIA director to install an open Internet connection in his office."

Considering he was the top dog at the premiere intelligence agency in the world, maybe Mr. Petraeus could have learned a lesson from Department of Homeland Security Secretary Janet Napolitano, who in September proudly admitted to CNN that she doesn't have any kind of online presence. "Some would call me a Luddite but you know," Secretary Napolitano told CNN, "But that's my own personal choice and I'm very unique in that regard, I suspect."
