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.

Russia is currently in a battle against the West, aggressively promoting Sputnik V to Europe and other regions and conducting sophisticated hacking efforts, most recently through Solarwinds.

The report says Russian leader Vladimir Putin authorized a campaign to assist former President Donald Trump and undermine Joe Biden, though it was not on the same scale as Moscow's efforts in 2016.

With all the talk about domestic terrorism, you might assume there's a law against it. There's not. The storming of the Capitol has again raised the question about whether one is needed.

As Haines sat down for an interview with NPR, her aides handed out a declassified report blaming Saudi Arabia's crown prince for a brutal killing.

The Biden administration has released a two-page summary saying that Saudi Arabia's Crown Prince Mohammed bin Salman approved the 2018 killing of journalist Jamal Khashoggi.

Khashoggi was killed during a visit to the Saudi Consulate in Istanbul in 2018. The report is expected to damage the already complicated relations between the traditional allies.

Burns said his top priority as spy chief would be a rising China. He received strong bipartisan support in testimony before the Senate Intelligence Committee and was widely expected to be confirmed.

When COVID hit, a Chinese firm offered to set up testing labs in the U.S., which could have given it access to DNA data. The U.S. says this is part of China's effort to collect mass data on Americans.

President Biden has a long to-do list when it comes to cybersecurity. He has to deal with a major cyber breach still under investigation, and there's a running debate over online conspiracy campaigns.

The Department of Homeland Security is warning about the threat of an attack by domestic extremists. The department says the recent mob assault on the U.S. Capitol may have emboldened radical groups.

President-elect Joe Biden's top picks for national security and foreign policy positions face Senate confirmation hearings Tuesday. They will be questioned on a range of challenges facing the U.S.
