The U.S. government report is the most substantial public effort to date to address decades of speculation about UFOs and whether the government had a role in concealing information.

The president says the U.S. will respond if it keeps getting hit with cyber attacks linked to Russia. But Putin has shown little interest in combatting cyber crimes called 'ransomware-as-a-service.'

Recent cybersecurity attacks in the U.S. were traced to Russian groups, who likely are known to the Kremlin.

If you're planning a multi-million dollar ransomware attack, there's really only one way to collect - with cryptocurrency. It's fast. It's easy. Best of all, it's largely anonymous and hard to trace.

Russian spies have penetrated U.S. government computer networks. Russian criminals have hit the U.S. gasoline and meat supplies. Can the president figure out how to stop the non-stop intrusions?

JBS, the world's biggest meat-packing company, expects operations to be back near full capacity Thursday as it recovers from a ransomware attack. Groups with ties to Russia are blamed for the attack.

The meat processing company JBS expects most operations to be restored Wednesday after a ransomware attack. It's the latest major company being shut down by apparent Russian criminal hackers.

JBS, the world's largest meat processor, has been hit by hackers, threatening the firm's operations in the U.S. and Australia. The case illustrates the growing threat hackers pose to key industries.

The latest Israeli-Palestinian fighting did not resolve any of the core issues in the decades-old dispute. But it did reveal several new dynamics likely to influence the conflict in the coming years.

There was a time when the U.S. believed an Israeli-Palestinian peace deal was critical to U.S. policy in the Middle East. These days, the goals are far more modest.

President Biden and the Pentagon say that after U.S. forces leave Afghanistan they will still assist that country from afar. But what precisely does that mean and can it be effective?

Following a ransomware attack on a major U.S. pipeline, President Biden announced his broad plan to make both the U.S. government and private companies more secure against future cyber breaches.

The Biden administration says cybercriminals in Russia are suspected in a ransomware attack on a gas pipeline. Yet this hack is very different from another big intrusion blamed on Russia last year.

A petroleum pipeline stretching from Texas to New York remains shut due to a ransomware attack. President Biden is calling for new infrastructure, yet the attack shows the threat to existing systems.

Exploding cigars. Poisoned pens. The CIA had lots of failed plots to kill Cuban leader Fidel Castro. But the first such plan was directed at his brother Raúl, who just retired at age 89.

Hackers say they've seized computer records from the Washington, D.C., police and are demanding ransom. As ransomware groups keep getting more sophisticated, law enforcement is struggling to keep up.

President Biden's decision to withdraw U.S. troops from Afghanistan raises questions about whether the Afghan government and the Taliban will work a political deal or keep fighting on the battlefield.

The intelligence community views four countries as posing the main security challenges over the next year: China, followed by Russia, Iran and North Korea.

By law, the government can't monitor domestic Internet traffic. Hackers suspected of being Russian exploited this blind spot by disguising their origins and working through unwitting U.S. companies.

Many Florida high schools now teach a cybersecurity program. There's a larger plan to help students figure out what is and isn't true online. Organizers hope it will become a nationwide model.
