It is the government's idea of a really bad day: Washington's Metro subway trains shut down. Seaport computers in New York go dark. Bloggers reveal locations of railcars with hazardous materials. Airport control towers are disrupted in Philadelphia and Chicago. Overseas, a mysterious liquid is found in London's subway.
And that was just for starters.
The fictitious international calamities were among dozens of detailed, mock disasters confronting officials in rapid succession in the US government's biggest-ever "Cyber Storm" war game, according to hundreds of pages of heavily censored files obtained by reporters. The Homeland Security Department ran the exercise to test the US' hacker defenses, with help from the State, Defense and Justice departments, the CIA, the National Security Agency and others.
The laundry list of fictional catastrophes, which include hundreds of people on "No Fly" lists arriving suddenly at US airport ticket counters, is significant because it suggests what kind of real-world trouble keeps people in the White House awake at night.
Imagined villains include hackers, bloggers, even reporters. After mock electronic attacks overwhelmed computers at the Port Authority of New York and New Jersey, an unspecified "major news network" airing reports about the attackers refused to reveal its sources to the government. Other simulated reporters were duped into spreading "believable but misleading" information that worsened fallout by confusing the public and financial markets, according to the government's files.
The US$3 million, invitation-only war game simulated what the US described as plausible attacks over five days in February 2006 against the technology industry, transportation lines and energy utilities by anti-globalization hackers. The government is organizing another multimillion-dollar wargame, Cyber Storm 2, to take place early next month.
"They point out where your expectations of your capabilities may be overstated," Homeland Security Secretary Michael Chertoff said. "They may reveal to you things you haven't thought about. It's a good way of testing that you're going to do the job the way you think you were."
Reporters obtained the Cyber Storm internal records nearly two years after it requested them under the Freedom of Information Act. The government censored most of the 328 pages it turned over, marked "For Official Use Only," citing rules preventing the disclosure of sensitive information.
"Definitely a challenging scenario," said Scott Algeier, who runs a cyber-defense group for leading technology companies, the Information Technology Information Sharing and Analysis Center.
For the participants -- who included government officials from the US, England, Canada, Australia and New Zealand and executives from leading technology and transportation companies -- the mock disasters came fast and furious: Hacker break-ins at an airline; stolen commercial software blueprints; problems with satellite navigation systems; trouble with police radios in Montana; school closures in Washington, Miami, Florida and New York City; computer failures at border checkpoints.
The incidents were divided among categories: computer attacks, physical attacks or psychological operations.
"We want to stress these players," said Jeffrey Wright, the former Cyber Storm director for the Homeland Security Department. "None of the players took 100 percent of the correct, right actions. If they had, we wouldn't have done our job as planners."
How did they do? Reviews were mixed. Companies and governments worked successfully in some cases.
Crucial players did not understand the role of the premier US organization responsible for fending off major cyber attacks, called the National Cyber Response Coordination Group, and it lacked sufficient technical experts.
Also, the sheer number of mock attacks complicated defensive efforts.
The little-known Cyber Response group, headed by the departments of Justice and Homeland Security, represents the largest US government departments and includes law enforcement and intelligence agencies. It is the principal organization for responding to cyber attacks and recovering from them.
The exercise had no impact on the real Internet. Officials said they were careful to simulate attacks only using isolated computers, working from basement offices at the Secret Service's headquarters in downtown Washington.
The government's files hint at a tantalizing mystery: In the middle of the wargame, someone quietly attacked the very computers used to conduct the exercise. Perplexed organizers traced the incident to overzealous players and sent everyone an urgent e-mail marked "IMPORTANT!" reminding them not to probe or attack the game computers.
"Any time you get a group of [information technology] experts together, there's always a desire, `Let's show them what we can do,'" said George Foresman, a former senior Homeland Security official who oversaw Cyber Storm. "Whether its intent was embarrassment or a prank, we had to temper the enthusiasm of the players."
The conflict in the Middle East has been disrupting financial markets, raising concerns about rising inflationary pressures and global economic growth. One market that some investors are particularly worried about has not been heavily covered in the news: the private credit market. Even before the joint US-Israeli attacks on Iran on Feb. 28, global capital markets had faced growing structural pressure — the deteriorating funding conditions in the private credit market. The private credit market is where companies borrow funds directly from nonbank financial institutions such as asset management companies, insurance companies and private lending platforms. Its popularity has risen since
The Donald Trump administration’s approach to China broadly, and to cross-Strait relations in particular, remains a conundrum. The 2025 US National Security Strategy prioritized the defense of Taiwan in a way that surprised some observers of the Trump administration: “Deterring a conflict over Taiwan, ideally by preserving military overmatch, is a priority.” Two months later, Taiwan went entirely unmentioned in the US National Defense Strategy, as did military overmatch vis-a-vis China, giving renewed cause for concern. How to interpret these varying statements remains an open question. In both documents, the Indo-Pacific is listed as a second priority behind homeland defense and
Every analyst watching Iran’s succession crisis is asking who would replace supreme leader Ayatollah Ali Khamenei. Yet, the real question is whether China has learned enough from the Persian Gulf to survive a war over Taiwan. Beijing purchases roughly 90 percent of Iran’s exported crude — some 1.61 million barrels per day last year — and holds a US$400 billion, 25-year cooperation agreement binding it to Tehran’s stability. However, this is not simply the story of a patron protecting an investment. China has spent years engineering a sanctions-evasion architecture that was never really about Iran — it was about Taiwan. The
In an op-ed published in Foreign Affairs on Tuesday, Chinese Nationalist Party (KMT) Chairwoman Cheng Li-wun (鄭麗文) said that Taiwan should not have to choose between aligning with Beijing or Washington, and advocated for cooperation with Beijing under the so-called “1992 consensus” as a form of “strategic ambiguity.” However, Cheng has either misunderstood the geopolitical reality and chosen appeasement, or is trying to fool an international audience with her doublespeak; nonetheless, it risks sending the wrong message to Taiwan’s democratic allies and partners. Cheng stressed that “Taiwan does not have to choose,” as while Beijing and Washington compete, Taiwan is strongest when
