An American journalist has been found guilty of helping hacktivist group Anonymous deface the website of the Los Angeles Times.
Prosecutors said Matthew Keys, 28, provided the hackers a password to access systems belonging to Tribune Co, the newspaper's parent company.
Prosecutors said Keys used online chat channels to encourage the hacktivists.
Sentencing will take place in January, but he is not expected to receive the maximum possible sentence of 25 years.
A spokesman for the US Justice Department told Reuters the sentence would likely be less than five years.
Keys' lawyer said he planned to appeal the verdict.
Keys was charged with conspiracy to cause damage to a protected computer, transmission of malicious code, and attempted transmission of malicious code. He was found guilty on all three counts.
Court documents said the incidents took place in December 2010, shortly after Keys had lost his job at California-based TV station Fox 40 KTXL, also owned by Tribune Co.
Keys went on to work for Reuters as the agency's social media editor, but was let go after he was charged in 2012.

'Elect Chippy 1337'

Prosecutors said Keys' actions were "anonymous revenge".
Under the online pseudonym AESCracked, Keys was said to have shared log-in details for the LA Times' content management system - CMS - the software used to enter content, such as articles or pictures, to be published on the newspaper's website.
With this information, an unidentified Anonymous member using the name "sharpie" is said to have edited a story on the LA Times site.
A headline was altered to read: "Pressure builds in House to elect CHIPPY 1337".
Within the article, the opening paragraph was also changed to include the phrase "reluctant House Democrats told to SUCK IT UP".
The defacement was "live" on the LA Times site for about an hour, the defence said.

Russia's growing military involvement in the Syria conflict is expected to be high on the agenda as Nato defence ministers meet in Brussels.
It comes after Nato member Turkey complained that Russian jets had repeatedly violated its airspace.
Ministers are also expected to review a range of measures introduced in the wake of the Ukraine crisis.
BBC defence correspondent Jonathan Marcus says the alliance aims to make clear it will respond to any challenge.
Nato ministers are expected to express their solidarity with Turkey and also address increased concern among Baltic members following Russia's involvement in eastern Ukraine.
UK Defence Secretary Michael Fallon is expected to announce that Britain is ready to make a long-term troop deployment to the Baltic republics, our correspondent says.
But, he adds, ministers are meeting amid a deepening sense of crisis.

A Brazilian audit court has ruled that President Dilma Rousseff broke the law in managing last year's budget.
The government was accused of borrowing money illegally from state banks to make up for budget shortfalls.
The opposition says the ruling by the Federal Accounts Court - which reports to Congress - paves the way for impeachment proceedings against Ms Rousseff.
She was re-elected less than a year ago but has record low popularity ratings.
The Brazilian government says it would challenge Wednesday's ruling in the Supreme Court.
"The game is not over," said Attorney General Luis Adams.
The minister who handled the case in the Accounts Court, Augusto Nardes, said the government disregarded fiscal and constitutional principles in the handling of the 2014 accounts.

Recession and corruption

If the decision is upheld by the Supreme Court, the government's accounts will then be assessed by the Congress, where Ms Rousseff's coalition has a majority.
This is the latest in a series of setbacks for Ms Rousseff.
On Tuesday, Brazil's top electoral authority said that it would re-open an investigation into alleged misuse of funds during Ms Rousseff's re-election campaign.
The Supreme Electoral Court will try to determine if Ms Rousseff's and Vice-President Michel Temer's campaign drew on donations from illegal sources.
The probe was requested by the opposition PSDB party.
The Brazilian economy has gone into recession and is expected to shrink by 3% this year.
The government's popularity has fallen amid corruption scandals involving senior politicians from Ms Rousseff's Worker's Party and other coalition members.

US President Barack Obama has apologised to the president of aid agency Medecins San Frontieres (MSF) for a bombing that killed at least 22.
The US has said the bombing, which took place in the Afghan city of Kunduz, was a mistake and it was attempting to strike the Taliban.
MSF wants the bombing to be investigated as a war crime.
Mr Obama has also apologised to the president of Afghanistan.
"If it is necessary to hold individuals accountable, that will be done," said White House spokesman Josh Earnest.
Mr Obama "expressed his condolences" to MSF president Joanne Liu, said Mr Earnest.
"In the United States when we make mistakes, we're honest about it. We own up to it," he said.

Mr Earnest also hinted at the possibility of paying victims and their families, a Department of Defense policy.
He said he could not say legally whether the bombing was a war crime but the US "goes to great lengths to limit the loss of life" of civilians.
In a statement, MSF said they received the apology but it was still demanding the International Humanitarian Fact-Finding Commission (IHFFC) investigate.
MSF has said it would not trust internal military inquiries into the bombing.
The IHFFC was set up in 1991 under the Geneva Conventions.
MSF says the co-ordinates of the hospital were well-known and its bombing could not have been a mistake.
A number of inquiries have been ordered - by the US justice department, the Pentagon, Nato and an American-Afghan team.

Islamic State (IS) militants fired mortar rounds containing mustard agent at Kurdish peshmerga fighters in northern Iraq, Kurdish officials say.
The Ministry of Peshmerga Affairs said blood samples from about 35 fighters revealed traces of sulphur mustard.
It did not say if any of the peshmerga had died as a result of the attack, or how severely they had been wounded.
Mustard gas can burn skin and cause severe respiratory problems, and is banned under international law.
The exposure took place along the front lines near the northern Iraqi towns of Makhmour and Gwer, the ministry said in a statement.
Roughly 37 mortars were fired in the attack, the statement added, "releasing white smoke and a black liquid".
The ministry called on countries fighting IS to give peshmerga fighters equipment for protection against chemical attacks. Several countries including the United States are already giving military assistance to the Kurdish fighters.

Chlorine gas

This is not the first time IS has been accused of using chemical weapons. In March, Kurdish authorities in Iraq said they had evidence that IS had used chlorine gas.
That allegation, by the Kurdistan Region Security Council, followed similar claims that the group had used low-grade chemical weapons against Iraqi security forces.
The director of the Organisation for the Prohibition of Chemical Weapons expressed "serious concern" in August over the possibility IS was using prohibited chemical weapons.
The UN recently adopted a resolution aimed at identifying those behind chemical weapons attacks in Syria.
IS already has a large arsenal of conventional weapons and military vehicles seized from the Iraqi army, much of it produced by the United States.
Iraq Kurds were the victim of a major chemical weapons attack by the Iraqi military under Saddam Hussein in 1988, which left thousands dead in the city of Halabja.

A man who flew a drone into a football stadium in Serbia during a Euro 2016 qualifier last October has been arrested ahead of the return leg in Albania.
Ismail Morinaj was detained after giving an interview in which he admitted carrying a gun for protection.
Last year's match had to be abandoned as Serbian fans invaded the pitch and attacked Albanian players.
Security for the Serbia team is high in Albania before Thursday's match.

Although the match will take place in Elbasan, an hour's drive to the south-east of Tirana, the Serbia team are staying at a hotel in the capital surrounded by police.
Reports from Tirana spoke of roads inside the city being closed amid a major police operation.
Albania are third in their Euro 2016 qualifying group, behind Portugal and Denmark, but far ahead of Serbia and still hoping to qualify for the knock-out stages of the competition.
Police arrested the 33-year-old suspect and three other men, saying they had found a Zastava pistol and several cartridges, as well as 36 tickets for Thursday's match.
Tensions had already been high before the Euro 2016 tie at the Partizan Stadium in Belgrade and ordinary Albanian fans were not allowed to attend the match.
The two countries have had a long and bitter history of rivalry, and ethnic-Albanian-majority Kosovo's decision to declare independence from Serbia in 2008 brought relations to a new low.
Ismail Morinaj admitted flying the drone from a church across the road from the stadium. As it hovered above the pitch, a large "greater Albania" flag could be seen, portraying nationalist claims to neighbouring states.

A group of New York inmates have out debated Harvard University's team - the top-ranked club in the world.
Last month, inmates at the Eastern New York Correctional Facility challenged the Harvard team to a debate at the maximum-security lockup.
The prison offers courses taught by faculty from nearby Bard College and the inmates have formed a popular debate club.
The friendly competition ended in a win for the prison's team.
This is not the first win for the Eastern New York Correctional team.
In the two years since starting the club they have challenged and beaten teams from the University of Vermont and the US Military Academy at West Point, with whom they have established an annual match and a budding rivalry.
The Harvard victory may be their biggest success; the Harvard team have won both the national and world championships.
In the match, inmates defended the premise that students whose parents entered the US illegally should be turned away from schools.
The debate was judged by a neutral panel.
Shortly after their loss Harvard students posted on the team's Facebook page.
"There are few teams we are prouder of having lost a debate to than the phenomenally intelligent and articulate team we faced this weekend,"' they wrote. "And we are incredibly thankful to Bard and the Eastern New York Correctional Facility for the work they do and for organizing this event."

At Bard, those who help teach the inmates aren't particularly surprised by their success.
"Students in the prison are held to the exact same standards, levels of rigor and expectation as students on Bard's main campus," said Max Kenner, executive director of the Bard Prison Initiative, which operates in six New York prisons. "Those students are serious. They are not condescended to by their faculty."
The initiative allows inmates to earn a range of degrees mostly taught by Brad professors all taught without access to the internet.
About 15% of all prisoners at Eastern New York Correctional are registered and some graduates have continued their studies at Yale and Columbia universities, according to Kenner.
