After weeks of rumors and speculation, it looked like the mystery surrounding the hackers who hit and embarassed Sony Pictures in the last few weeks may have finally been solved: North Korea did it, according to anonymous U.S. officials quoted in various news reports on Wednesday.

"We have found linkage to the North Korean government," said one of the anonymous sources.

But despite government officials pointing the finger at North Korea — behind the comfort and safety of anonymous quotes — there is still little evidence linking the Sony hackers to the regime led by Kim Jong-un, and cybersecurity experts are just as unconvinced of this theory as they were more than two weeks ago.

"This is the story that doesn't want to die," Sean Sullivan, a researcher at Finnish security firm F-Secure, told Mashable.

And it doesn't die, he added, because the hackers have been playing into the narrative spread by media outlets. "These guys are very Internet media savvy and are keeping the story alive to make it painful for Sony so that Sony has a reason to meet their demands."

In fact, as Wired's Kim Zetter pointed out, the hackers made the first reference to the movie The Interview only after a week of news coverage. And as we have reported before, the hackers behind the attack made no mention of North Korea or the Seth Rogen and James Franco movie in their email to Sony executives, sent days before they wiped the company's computers.

In that message, the hackers actually seemed more interested in extorting the company for money.

"[M]onetary compensation we want. Pay the damage, or Sony Pictures will be bombarded as a whole. You know us very well. We never wait long," the email, first spotted by Mashable, read. "You’d better behave wisely."

Other cybersecurity experts are also very skeptical, mostly because apart from anonymous quotes, there is still very little evidence that points to North Korea.

"Public evidence is still very circumstantial and there is much in the hacks that would lead one to conclude it is not a nation state," Adam Segal, a Council on Foreign Relations expert on cybersecurity, told Mashable, referring to the hackers' modus operandi, their bravado and threats, as well as their apparent focus on financial gain.

Those are some of the reasons for skepticism laid out in an exhaustive blog post by Marc Rogers, the Principal Security Researcher at CloudFlare.

"Occam’s razor suggests the simpler explanation of an insider. It also fits with the pure revenge act that this started out as," Rogers wrote.

Jeffrey Carr, a a cybersecurity expert and CEO of Taia Global, pushed journalists and experts to demand to see the actual evidence behind this accusations before buying them, and also added another dose of skepticism.

"Is North Korea responsible for the Sony breach?" he wrote in a blog post. "I can't imagine a more unlikely scenario than that one."

His call for more proof was echoed by Graham Cluley, another renowned Internet security expert.

"I would like to have answers to a few more questions, and hear some of the evidence, before falling behind the claim that North Korea has orchestrated the attack against Sony," he wrote.

Following Wednesday's reports, the White House National Security Council released a statement that made no mention of North Korea and only said that the United States "is working tirelessly to bring the perpetrators of this attack to justice" and "is investigating attribution and will provide an update at the appropriate time."

President Barack Obama talked about the hack on ABC News on Wednesday night too, but didn't venture into accusing North Korea either.

The FBI declined to comment. So did the NSA, whose spokesperson deferred to the FBI. The Department of Homeland Security also replied "no comment" when reached out to by Mashable.

Ultimately, it seems like we are exactly where we were a couple of weeks ago. Everyone is accusing North Korea, but there's still no evidence to support the theory.

"I can tell you I don't know who is behind it," Sullivan, the F-Secure researcher, told Mashable, attempting to explain why the administration anonymously accused North Korea. "[But] the White House cannot say that. Institutionally, it is incapable of saying 'we don't know.'"
